A description of the integrating model for photovoltaic venture analysis is given; input assumptions for the model are described; and the integrating model program listing is given. The integrating model is an explicit representation of the interactions between photovoltaic markets and supply under alternative sets of assumptions. It provides a consistent way of assembling and integrating the various assumptions, data, and information that have been obtained on photovoltaic systems supply and demand factors. Secondly, it provides a mechanism for understanding the implications of all the interacting assumptions. By representing the assumptions in a common, explicit framework, much more complex interactions can be considered than are possible intuitively. The integrating model therefore provides a way of examining the relative importance of different assumptions, parameters, and inputs through sensitivity analysis. Also, detailed results of model sensitivity analysis and detailed market and systems information are presented. (WHK)

This document tries to study the development and evolution of the photovoltaic market at a national land international scale, and to analyse its current status at the end of 2001. The paper broaches the study from different points of view. At the first step, the actual great expansion of the global market is analysed by means of the data for international sales and shipments of photovoltaic modules which are completed with figures of the main countries and manufacturing companies involved in the market, the end-use applications, the installed power per country, the technologies used and the evolution of the cost of the modules. By using the same kind of parameters, the particular conditions of the Spanish market is then analysed, and the current national norms and plans for promotion and their short-term perspectives are reviewed and discussed. As a complementary/aspect , a simple cost analysis of the main components of a photovoltaic system in the Spanish market is carried out, together with the costs of complete installations. The average values for components and systems are obtained and are compared with those from preceding years. These data allow evaluating in practice how the global situations is reflected in the final cost of the photovoltaic devices for consumers. (Author) 56 refs.

Residential solar photovoltaic market stimulation: Japanese and Australian lessons for Canada

International Nuclear Information System (INIS)

Parker, Paul

2008-01-01

Canada is a leading electricity consumer, yet lags behind other industrial countries (14th out of 20 reporting IEA countries) in the installation of solar photovoltaic systems. The factors (environmental benefits, health benefits, network benefits, need for new production capacity, etc.) promoting solar or other renewable sources of electricity in other countries are also present in Canada, but effective policy mechanisms to stimulate Canada's photovoltaic industry are only starting to appear. Discussions of policy options focused initially on renewable portfolio standards and then on feed-in tariffs. This paper reviews the Japanese and Australian experience with capital incentives to stimulate the residential market for photovoltaics. It demonstrates the ability of a market-sensitive program to stimulate industrial growth, achieve unit cost reductions and shift the market to include a large grid-tied share. Residential respondents to surveys report high costs as their primary barrier to installing photovoltaic systems and state a strong preference for capital incentives to reduce their investment costs. The Canadian government needs a market stimulation policy if it is to join those countries where a decentralized photovoltaic generation system strengthens the electricity supply system. A balanced solar energy market stimulation program is proposed that combines a feed-in tariff with a declining capital incentive. (author)

The european photovoltaic market once again reached the heights in 2006, thanks to the dynamism of the German market. White paper objectives have thus been fulfilled four years ahead of schedule. The european photovoltaic sector remains however very heterogeneous with both an ultra-dominant German market (estimated at 1150 MWp in 2006) and other countries of the European Union that vary from a few kWP to a few dozen MWp. This analysis provides statistical data on the market, the capacity installed during 2005 and 2006, the photovoltaic parks and the evolution of the photovoltaic cell production. (A.L.B.)

Ragsdale, C.; Quashie, P.

1980-01-01

The potential market of photovoltaic systems in remote village applications in developing countries is assessed. It is indicated that photovoltaic technology is cost-competitive with diesel generators in many remote village applications. The major barriers to development of this market are the limited financial resources on the part of developing countries, and lack of awareness of photovoltaics as a viable option in rural electrification. A comprehensive information, education and demonstration program should be established as soon as possible to convince the potential customer countries and the various financial institutions of the viability of photovoltaics as an electricity option for developing countries.

The German Market for photovoltaic (solar-produced electricity)

International Nuclear Information System (INIS)

1999-06-01

In preparation for reducing the CO2 emission and in so living up to the Kyoto-protocol with the succeeding changes, renewable energy has - including photovoltaic - got an increasing importance in the world over - especially in Germany. If the technical potentials in Germany are utilized optimally, then 75% of the total German electricity production with photovoltaic are covered. At the moment it is only about 1 per thousand. There is a political will to promote photovoltaic in Germany, which results in high account prices and different plant supporting programmes. In the coming 6 years the official aim is that a minimum of 100.000 photovoltaic power plants are installed with an average capacitate for 3 kWp. The competition for the market is hard. There are many national and international suppliers, so the co-operations between the large German producers seem to be obvious. (EHS)

Economic analysis of photovoltaic systems for the residential market under China's new regulation

International Nuclear Information System (INIS)

Rodrigues, Sandy; Chen, Xiaoju; Morgado-Dias, F.

2017-01-01

China has recently changed its regulation for producing energy from photovoltaic solar panels in order to encourage the use of the solar resource. This new regulation started with offering subsidies at a national level and this was later followed by local subsidies in addition to the national one. Being a large country, China has regions with good solar exposure and others with poor exposure. Each region has a different electricity price and the energy is purchased based on the Grid Coal Power electricity price that also varies throughout the country. In this work we analyze the economic profitability of different regions considering the solar radiation levels, savings in self-consumption, cash flows from injecting power into the grid and local prices for installations to show that the best return is obtained in the places with better solar radiation or where the electricity price is higher. The regional Feed-In tariffs help to compensate for lower radiation levels but do not make these regions very attractive from an investment perspective. - Highlights: • Summarizes national and local feed in tariffs for China for the residential market. • Provides average local prices for 1 kW, 3 kW and 5 kW photovoltaic installations. • Selects city with best IRR, NPV and DPBP based on prices, subsidies and radiation. • Performs sensitivity analysis to check which parameter has more effect on results.

In 2009, the photovoltaic (PV) industry expanded greatly in China. Developing PV technology is both necessary and urgent, as China is a large country, which consumes huge amounts of energy. In addition, because China has a natural advantage of excellent solar resources, its government has provided significant support in this field. In order to motivate the PV industry, the Ministries of Finance and Construction established coordinated policies to offer financial inducements. The government will implement the Jintaiyang project in the near future: 15 billion US dollars will be invested and 294 demonstration projects will be built. The developing Chinese PV market holds great promise. The aim of this paper is to analyze the present status of the Chinese PV market, discuss the opportunities available, and the potential challenges anticipated in the developing process including some engineering roadblocks encountered in the PV system, and to outline possible future scenarios in this field. - Research highlights: → In 2009, the photovoltaic (PV) industry expanded greatly in China. → The price of electricity generated by PV will be gradually reduced. → A photovoltaic industrial chain in China has already formed. → Research on PV systems will also promote the development of improved technologies.

Sandia National Laboratories, working with Energy Sense Finance developed the proof-ofconcept PV Valueª tool in 2011 to provide real estate appraisers a tool that can be used to develop the market value and fair market value of a solar photovoltaic system. PV Valueª moved from a proof-of-concept spreadsheet to a commercial web-based tool developed and operated exclusively by Energy Sense Finance in June 2014. This paper presents the results of a survey aimed at different user categories in order to measure how the tool is being used in the marketplace as well as elicit information that can be used to improve the tools effectiveness.

PV Status Report 2009. Research, Solar Cell Production and Market Implementation of Photovoltaics

Jaeger-Waldau, A.

2009-08-01

Photovoltaics is a key technology option to realise the shift to a decarbonised energy supply. The solar resources in Europe and world wide are abundant and cannot be monopolised by one country. Regardless for what reasons and how fast the oil price and energy prices increase in the future, Photovoltaics and other renewable energies are the only ones to offer a reduction of prices rather than an increase in the future. As a response to the economic crisis, most of the G20 countries have designed economic recovery packages which include 'green stimulus' measures. However, compared to the new Chinese Energy Revitalisation Plan under discussion, the pledged investments in green energy are marginal. If no changes are made, China which now strongly supports its renewable energy industry, will emerge even stronger after the current financial crisis. In 2008, the Photovoltaic industry production almost doubled and reached a world-wide production volume of 7.3 GWp of Photovoltaic modules. Yearly growth rates over the last decade were in average more than 40%, which makes Photovoltaics one of the fastest growing industries at present. Business analysts predict the market volume to increase to 40 billion euros in 2010 and expect lower prices for consumers. The trend that thin-film Photovoltaics grew faster than the overall PV market continued in 2008. The Eighth Edition of the 'PV Status Report' tries to give an overview about the current activities regarding Research, Manufacturing and Market Implementation.

Photovoltaic marketing in developing countries

Photovoltaic (PV) insolation-harnessing is acknowledged as the most practical economic solution to meet the requirements of one hundred million people without electricity in the developing countries. Industrialised countries in particular, have been active in utilising such technologies because they can afford the current peak watt prices of US $3-15 for such systems. The market in those countries will soon be close to saturation and attention by suppliers will have to be shifted to the already established larger market in less developed countries (LDCs). PV marketing in these developing countries, i.e. ability to penetrate the potential market, is facing tremendous hurdles. This paper reviews the present status and future directions of the PV market in developing countries as well as discusses the current technical, social, financial or geopolitical barriers and constraints, which are in line with the trends in the world. The paper concludes by making a global policy package proposal, in terms of an appeal on the global community concerned with PV to propagate proposal, in terms of an appeal on the global community concerned with PV to propagate this proposal more convincingly, perhaps to emanate from an internationally recognised 'forum', like a PV conference and exhibition, with cooperation and participation of PV manufacturers, suppliers, industrialised countries, NGOs, financial institutions and developing countries.

Photovoltaics for Buildings: Key Issues in Pursuit of Market Readiness

International Nuclear Information System (INIS)

Sheila, J.; Hayter, P.E.

1998-01-01

The photovoltaic (PV) industry is rapidly beginning to recognize the market potential of the buildings sector. New PV-for-buildings products have recently become commercially available, and numerous products that are under development will be introduced within the next 5 years. To ensure that these new products will be adopted and used in common building practices, the PV industry should recognize and address important buildings industry issues. These issues include building codes and standards, after-market servicing, education, and warranties and insurance policies. Photovoltaic systems are also still very expensive. The simplest method for increasing their value for a building is to decrease the building's electrical loads through energy efficiency and conservation. Meeting these goals can only be accomplished through partnerships with the U.S. Department of Energy (DOE), private industry, and public institutions

The high cost of power from solar photovoltaic (PV) panels has been a major deterrent to the technology’s market penetration. Proponents have argued, however, that typical analyses overlook many of the benefits of solar PV. Some of those benefits are in the realm of environmental and security externalities, but others occur within the electricity markets. In this paper, I attempt to do a more complete market valuation of solar PV. I incorporate the fact that power from solar PV panels is gene...

Photovoltaic module quality in the Kenyan solar home systems market

International Nuclear Information System (INIS)

Duke, R.D.; Jacobson, A.; Kammen, D.M.

2002-01-01

As one of the largest unsubsidized markets for solar home systems (SHSs) in the world, Kenya represents a promising model for rural electrification based on private purchases of clean decentralized photovoltaic technologies. Small amorphous-silicon modules dominate the market and most brands provide high quality and affordable service. Product quality varies widely, however, and the public has limited capacity to distinguish among competing brands. This imposes direct hardships on households with the misfortune to purchase low-quality equipment, and it constrains sales as some customers refrain from purchasing solar equipment due to the associated performance uncertainty. This article analyzes market failure associated with photovoltaic module quality in the Kenyan SHS market and develops strategies to address the problem - emphasizing that similar quality problems may exist for other SHS components and in other markets. The principal conclusion is that domestic product testing with public disclosure represents an inexpensive low-risk strategy, but it may prove inadequate. Mandatory product quality standards based on international testing regimes (e.g. IEC standards), augmented with a basic domestic testing option, would provide stronger assurance, but the risks associated with this intervention suggest caution. An emerging multilateral SHS market support effort (PVMTI) should ensure quality for the credit-based sales it promotes in Kenya; however, the long-term impact of this approach is not yet clear and it is unlikely to address quality problems associated with the unsubsidized sales-based markets for SHSs. Finally, fee-for-service models would decisively address quality problems, but launching this model in the Kenyan market would likely require large subsidies. (author)

Market assessment of photovoltaic power systems for agricultural applications in Morocco

Science.gov (United States)

Steingass, H.; Asmon, I.

1981-01-01

Results of a month-long study in Morocco aimed at assessing the market potential for stand-alone photovoltaic systems in agriculture and rural service applications are presented. The following applications, requiring less than 15 kW of power, are described: irrigation, cattle watering, refrigeration, crop processing, potable water and educational TV. Telecommunications and transportation signalling applications, descriptions of power and energy use profiles, assessments of business environment, government and private sector attitudes towards photovoltaics, and financing were also considered. The Moroccan market presents both advantages and disadvantages for American PV manufacturers. The principle advantages of the Moroccan market are: a limited grid, interest in and present use of PV in communications applications, attractive investment incentives, and a stated policy favoring American investment. Disadvantages include: lack of government incentives for PV use, general unfamiliarity with PV technology, high first cost of PV, a well-established market network for diesel generators, and difficulty with financing. The market for PV in Morocco (1981-1986), will be relatively small, about 340 kwp. The market for PV is likely to be more favorable in telecommunications, transport signalling and some rural services. The primary market appears to be in the public (i.e., government) rather than private sector, due to financial constraints and the high price of PV relative to conventional power sector.

New Markets for Solar Photovoltaic Power Systems

Over the past five years solar photovoltaic (PV) power supply systems have matured and are now being deployed on a much larger scale. The traditional small-scale remote area power supply systems are still important and village electrification is also a large and growing market but large scale, grid-connected systems and building integrated systems are now being deployed in many countries. This growth has been aided by imaginative government policies in several countries and the overall result is a growth rate of over 40% per annum in the sales of PV systems. Optimistic forecasts are being made about the future of PV power as a major source of sustainable energy. Plans are now being formulated by the IEA for very large-scale PV installations of more than 100 MW peak output. The Australian Government has announced a subsidy for a large solar photovoltaic power station of 154 MW in Victoria, based on the concentrator technology developed in Australia. In Western Australia a proposal has been submitted to the State Government for a 2 MW photovoltaic power system to provide fringe of grid support at Perenjori. This paper outlines the technologies, designs, management and policies that underpin these exciting developments in solar PV power.

2008-09-01

Photovoltaics is a solar power technology to generate electricity using semiconductor devices, known as solar cells. A number of solar cells form a solar 'Module' or 'Panel', which can then be combined to solar systems, ranging from a few Watts of electricity output to multi Megawatt power stations. The unique format of the Photovoltaic Status Report is to combine international up-to-date information about Research Activities with Manufacturing and Market Implementation data of Photovoltaics. These data are collected on a regular basis from public and commercial studies and cross-checked with personal communications. Regular fact-finding missions with company visits, as well as meetings with officials from funding organisations and policy makers, complete the picture. Growth in the solar Photovoltaic sector has been robust. Yearly growth rates over the last five years were on average more than 40%, thus making Photovoltaics one of the fastest growing industries at present. Business analysts predict that the market volume will increase to 40 billion euros in 2010 and expect rising profit margins and lower prices for consumers at the same time. The PV Status Report provides comprehensive and relevant information on this dynamic sector for the public interested, as well as decision-makers in policy and industry.

For the second year in a row the photovoltaic market is in sharp decline in France, it dropped by 37% between 2011 and 2012 and the situation for 2013 is expected to be even worse. The last emergency measures taken by the government have been useless. The syndicate of renewable energies (SER) and the 'Europe Ecologie les Verts' party urge the government to take efficient emergency measures like for instance the implementation of local purchase tariffs instead of the present bidding process or to keep the obligation of the integration to the building only for new constructions. The only good piece of news is that photovoltaic power is getting more and more competitive. France has to reconsider its energy policy and its regulatory framework in order to benefit from it.

Zhang, Fang; Deng, Hao; Margolis, Robert; Su, Jun

2015-01-01

Beginning in 2013, China's photovoltaic (PV) market-development strategy witnessed a series of policy changes aimed at making distributed-generation PV (DG PV) development an equal priority with large-scale PV development. This article reviews the DG PV policy changes since 2013 and examines their effect on China's domestic DG PV market. Based on a 2014 survey of DG PV market and policy participants, we present cost and time breakdowns for installing DG PV projects in China, and we identify the main barriers to DG PV installation. We also use a cash flow model to determine the relative economic attractiveness of DG PV in several eastern provinces in China. The main factors constraining DG PV deployment in China include financial barriers resulting from the structure of the self-consumption feed-in tariff (FIT), ambivalence about DG PV within grid companies, complicated ownership structures for buildings/rooftops/businesses, and the inherent time lag in policy implementation from the central government to provincial and local governments. We conclude with policy implications and suggestions in the context of DG PV policy changes the Chinese government implemented in September 2014. -- Highlights: •We review China's distributed PV market development and policy changes since 2013. •We present cost and time requirements for installing distributed PV in China. •We conduct IRR analysis of distributed PV under different policy frameworks. •We identify barriers to China's distributed PV, especially feed-in tariff barriers

The global solar photovoltaic market enjoyed a strong revival in 2013. Preliminary estimates put it in excess of 37 GWp, compared to 30 GWp in 2012 and 2011. The solar photovoltaic sector led the annual installed capacity ratings for renewable energies, taking worldwide capacity up to 137 GWp by the end of the year which means a 35% year-on-year increase. At global level the high growth markets - China, Japan and America - contrast sharply with the contracting European Union market. The strong recovery of the global photovoltaic market is due to the drop in module prices which in some zones has dropped below the conventional electricity price. In the E.U, in 2013 the photovoltaic electricity reached 80.2 TWh while the capacity connected during this year was 9922.2 MWp. Concerning the capacity connected in 2013 the 2 main contributors in Europe are Germany (3310.0 MWc) and Italy (1462.0 MWc). These 2 countries represent also 68% of the cumulated and connected capacity in Europe. All along the article various charts and tables give the figures of the photovoltaic capacity per inhabitant for each E.U country in 2013, the electricity production from photovoltaic power for each E.U country, and the main photovoltaic module manufacturers in 2013 worldwide reporting production and turnover

This paper presents an optimal bid submission in a day-ahead electricity market for the problem of joint operation of wind with photovoltaic power systems having an energy storage device. Uncertainty not only due to the electricity market price, but also due to wind and photovoltaic powers is one of the main characteristics of this submission. The problem is formulated as a two-stage stochastic programming problem. The optimal bids and the energy flow in the batteries are the first-stage variables and the energy deviation is the second stage variable of the problem. Energy storage is a way to harness renewable energy conversion, allowing the store and discharge of energy at conveniently market prices. A case study with data from the Iberian day-ahead electricity market is presented and a comparison between joint and disjoint operations is discussed. - • Joint wind and PV systems with energy storage. • Electricity markets. • Stochastic optimization. • Day-ahead market.

spain and Germany set the pace for the world photovoltaic market in 2008, which grew to more than twice its 2007 size. The European Union continued to drive photocell installation with an additional 4 592.3 MWp in 2008, or 151.6% growth over 2007. However, European growth prospects for the photovoltaic market in 2009 are being dampened by the global financial crisis and the scheduled slow-down of the Spanish market. (author)

Thin Film Photovoltaics

Energy Technology Data Exchange (ETDEWEB)

Zweibel, K.

1998-11-19

The motivation to develop thin film technologies dates back to the inception of photovoltaics. It is an idea based on achieving truly low-cost photovoltaics appropriate for mass production and energy significant markets. The key to the idea is the use of pennies worth of active materials. Since sunlight carries relatively little energy in comparison with combustion-based energy sources, photovoltaic (PV) modules must be cheap to produce energy that can be competitive. Thin films are presumed to be the answer to that low-cost requirement. But how cheap do they have to be? The following is an oversimplified analysis that allows some insight into this question.

Household photovoltaic market in Xining, Qingha province, China: the role of local PV business

International Nuclear Information System (INIS)

Ling, S.; Boardman, B.

2002-01-01

This paper assesses the present and future market for household photovoltaic (PV) systems in rural Northwest China, especially from the PV commerce at Xining, Qinghai Province. This unsubsidised free market is now met by the emerging PV industry in China, which includes cell and module manufacturers, and PV system distributors and assemblers. For widespread deployment of such a renewable energy technology, the development of a local free market seems more successful than donor- or 'government subsidy'-driven programmes. Presently, there is a thriving infant PV industry in Northwest China, mostly centred in Xining. Xining-based PV sales companies have extensive networks for selling, marketing and servicing household PV systems for rural farmers and nomads. Small systems are now ordinary items on sale in local shops. Based on interviews and fieldwork observations with seven major PV sales companies in Xining, the household PV market is assessed from the present business operations of these companies. Detail of primary sources is given with the aim of archiving seminal progress in the history of photovoltaic power. The results suggest that although the household PV market will continue to grow, current government and international sponsored PV programmes can create both opportunities and barriers for the infant PV market an industry in China.

PV Status Report 2010. Research, Solar Cell Production and Market Implementation of Photovoltaics

International Nuclear Information System (INIS)

Jaeger-Waldau, A.

2010-08-01

Photovoltaics is a solar power technology to generate Electricity using semiconductor devices, known as solar cells. A number of solar cells form a solar 'Module' or 'Panel', which can then be combined to solar systems, ranging from a few Watts of electricity output to multi Megawatt power stations. The unique format of the Photovoltaic Status Report combines international up-to-date information about Research Activities with Manufacturing and Market Implementation data of Photovoltaics. These data are collected on a regular basis from public and commercial studies and cross-checked with personal communications. Regular fact finding missions with company visits, as well as meetings with officials from funding organisations and policy makers, complete the picture. Growth in the solar Photovoltaic sector has been robust. Yearly growth rates over the last decade were on average more than 40 %, thus making Photovoltaics one of the fastest growing industries at present. The PV Status Report provides comprehensive and relevant information on this dynamic sector for the public interested, as well as decision-makers in policy and industry.

Projected photovoltaic energy impacts on US CO2 emissions: an integrated energy environmental-economic analysis

Lee, J.C.; Fthenakis, V.M.; Morris, S.C.; Goldstein, G.A.; Moskowitz, P.D.

1997-01-01

The potential role of photovoltaic technologies in reducing carbon dioxide (CO 2 ) emissions in the USA was evaluated using an energy-environment-economic systems model. With a range of assumptions about future scenarios up to 2030, the model results provide an objective quantitative assessment of the prospects for photovoltaics in a competitive market. With the projected improvements in cost and efficiency, photovoltaics will compete favourably as a general source of electricity supply to the grid by about 2010 in southwestern USA. This analysis indicates that photovoltaics has the potential to reach a total installed capacity of 140 GW by the year 2030, and to displace a cumulative 450 million metric tons of carbon emissions from 1995 to 2030. At the projected 2030 capacity, photovoltaics could displace over 64 million metric tons of carbon emissions a year. Under constraints on carbon emissions, photovoltaics becomes more cost effective and would further reduce carbon emissions from the US energy system. (author)

Exergy analysis of photovoltaic solar collector

International Nuclear Information System (INIS)

Sopian, K.; Othman, M.Y.Hj.

1998-01-01

The exergy analysis (availability or second law analysis) is applied to the photovoltaic thermal solar collector. Photovoltaic thermal collector is a special type of solar collector where electricity and heat are produced simultaneously. The electricity produced from the photovoltaic thermal collector is all converted into useful work. The available quantity of the heat collected can readily be determined by taking into account both the quantity (heat quantity) and quality ( a function of temperature) of the thermal energy. Therefore, using the concept of exergy allows heat produced from the thermal collector and the electricity generated from the photovoltaic cells to be compared or to be evaluated on the basis of a common measure such as the effectiveness on solar energy collection or the total amount of available energy. In this paper, the effectiveness of solar energy collection is called combined photovoltaic thermal exergy efficiency. An experimental setup of a double pas photovoltaic thermal solar collector has been deigned, fabricated and tested. (author)

The infrastructure path to a sustainable world market for photovoltaics

International Nuclear Information System (INIS)

Fitzgerald, M.C.; Mrohs, M.

1997-01-01

As the markets for photovoltaics grow and become more main stream, customers and financing institutions will increasingly require assurances of design, installation, and maintenance competency and professionalism. This can either evolve as a large number of uncoordinated and dissimilar local and regional regulations, or may be developed within a common framework that ensures quality, continuity, and transportability, reducing the ultimate burden of compliance on designers and installers. This paper is a summary of the issues confronting efforts to develop industry standards, current efforts to develop global standards for systems hardware and training, and projections for the phased development of these quality programs for the photovoltaics industry. The paper also discusses the impact of such a standardization program on access to financing and the impact on the creation of local, sustainable jobs

This annual evaluation is a synthesis of works published in 2006. Comparisons are presented between the wind power performances and European Commission White Paper and Biomass action plan objectives. The european Union photovoltaic market reached the limits of the sector supply capacity for the first time. Meanwhile the prospects of growth in the photovoltaic market are still just as good as before. Silicon producers have finally responded to the expectations of the photovoltaic industry by announcing new production capacities. These extensions led to massively investing in new production capacities, in phase with ever greater demand. This increase in demand remains, however dependent upon the energy policy. (A.L.B.)

The european market showed all of its strength and soundness in 2005. The 2005 installed cells growth could have been even greater if the market had not been continually curbed by a lack of raw materials. Germany remained the leading photovoltaic market in the world in 2005, positioned far ahead of Japan and the USA. This unabashed success inspired both Spain and Italy, which set up conditions in order to rapidly develop their photovoltaic sectors. (A.L.B.)

Analysis of diffusion paths for photovoltaic technology based on experience curves

International Nuclear Information System (INIS)

Poponi, Daniele

2003-04-01

This paper assesses the prospects for diffusion of photovoltaic (PV) technology for electricity generation in grid-connected systems. The analysis begins with the calculation of the break-even price of PV systems and modules, which is the price that can assure commercial viability without incentives or subsidies. The calculated average break-even price of PV systems for building-integrated applications is about US dollars 3.2/W p but can go up to about US dollars 4.5/W p in areas with very good solar irradiation and if a low real discount rate is applied. These are higher values than the break-even prices estimated in the literature to date. PV system break-even prices for intermediate load generation in utility-owned systems are also calculated, their average being about US dollars 1/W p The methodology of experience curves is used to predict what would be the different levels of cumulative world PV shipments required to reach the calculated break-even prices of PV systems, assuming different trends in the relationship between price and the increase in cumulative shipments. The years in which the break-even levels of cumulative shipments could be theoretically obtained are then calculated by considering different market growth rates. Photovoltaics could enter the niche of building-integrated applications without incentives in the first years of the next decade, provided that the PR is 80% and the average annual world market growth rate is at least 15%. The final part of the paper analyzes the niche markets or applications that seem promising for the diffusion of photovoltaics in the next few years (Author)

2014-09-01

Subnational policies pertaining to photovoltaic (PV) systems have increased in volume in recent years and federal incentives are set to be phased out over the next few. Understanding how subnational policies function within and across jurisdictions, thereby impacting PV market development, informs policy decision making. This report was developed for subnational policy-makers and researchers in order to aid the analysis on the function of PV system incentives within the emerging PV deployment market. The analysis presented is based on a 'logic engine,' a database tool using existing state, utility, and local incentives allowing users to see the interrelationships between PV system incentives and parameters, such as geographic location, technology specifications, and financial factors. Depending on how it is queried, the database can yield insights into which combinations of incentives are available and most advantageous to the PV system owner or developer under particular circumstances. This is useful both for individual system developers to identify the most advantageous incentive packages that they qualify for as well as for researchers and policymakers to better understand the patch work of incentives nationwide as well as how they drive the market.

The value of price transparency in residential solar photovoltaic markets

Energy Technology Data Exchange (ETDEWEB)

O’Shaughnessy, Eric; Margolis, Robert

2018-06-01

Installed prices for residential solar photovoltaic (PV) systems have declined significantly in recent years. However price dispersion and limited customer access to PV quotes prevents some prospective customers from obtaining low price offers. This study shows that improved customer access to prices - also known as price transparency - is a potential policy lever for further PV price reductions. We use customer search and strategic pricing theory to show that PV installation companies face incentives to offer lower prices in markets with more price transparency. We test this theoretical framework using a unique residential PV quote dataset. Our results show that installers offer lower prices to customers that are expected to receive more quotes. Our study provides a rationale for policies to improve price transparency in residential PV markets.

For alternative energy technologies like photovoltaics (PV), the analysis of Research and Development (R and D) expenses is important to observe and understand market dynamics. This is, in turn, essential for policymakers. However, the quantitative evaluation of global corporate R and D investments is a challenging task due to unavailability or high scatter of precise data. Here we present a top-down approach to estimate the current and global historic cumulated PV R and D investments based on international PV patent applications. High growth rates of PV-related patents and R and D headcount accompany growth and development of the PV market and are an excellent indicator to analyze R and D investments. With this approach, current annual corporate PV R and D investments are found to be about 6000 m€ and show a rapidly increasing trend on a global scale. - Highlights: • Global corporate and public photovoltaic R and D spendings are presented and quantified. • Instead of company reports or governmental reports, alternative metrics are developed. • Basis for quantification are photovoltaic patent applications and research headcounts. • Patents are analyzed regarding their country of origin, year of filing, type of technology. • Ethical and political implications of energy R and D are discussed

Retrospective modeling of the merit-order effect on wholesale electricity prices from distributed photovoltaic generation in the Australian National Electricity Market

International Nuclear Information System (INIS)

McConnell, Dylan; Hearps, Patrick; Eales, Dominic; Sandiford, Mike; Dunn, Rebecca; Wright, Matthew; Bateman, Lachlan

2013-01-01

In electricity markets that use a merit order dispatch system, generation capacity is ranked by the price that it is bid into the market. Demand is then met by dispatching electricity according to this rank, from the lowest to the highest bid. The last capacity dispatched sets the price received by all generation, ensuring the lowest cost provision of electricity. A consequence of this system is that significant deployments of low marginal cost electricity generators, including renewables, can reduce the spot price of electricity. In Australia, this prospect has been recognized in concern expressed by some coal-fired generators that delivering too much renewable generation would reduce wholesale electricity prices. In this analysis we calculate the likely reduction of wholesale prices through this merit order effect on the Australian National Electricity Market. We calculate that for 5 GW of capacity, comparable to the present per capita installation of photovoltaics in Germany, the reduction in wholesale prices would have been worth in excess of A$1.8 billion over 2009 and 2010, all other factors being equal. We explore the implications of our findings for feed-in tariff policies, and find that they could deliver savings to consumers, contrary to prevailing criticisms that they are a regressive form of taxation. - Highlights: ► We model the impact of photovoltaic generation on the Australian electricity market. ► Photovoltaic generation depresses electricity prices, particularly in summer peaks. ► Over the course of a year, the depression in wholesale prices has significant value. ► 5 GW of solar generation would have saved $1.8 billion in the market over two years. ► The depression of wholesale prices offsets the cost of support mechanisms

The market potential in the Philippines for stand alone photovoltaic (P/V) systems in agriculture was assessed. Applications include: irrigation, postharvest operation, food and fiber processing and storage, and livestock and fisheries operations. Power and energy use profiles for many applications as well as assessments of business, government and financial climate for P/V sales are described. Many characteristics of the Philippine agriculture and energy sector favorably influence the use of P/V systems. However, serious and significant barriers prevent achieving the technically feasible, cost competitive market for P/V systems in the agricultural sector. The reason for the small market is the limited availability capital for financing P/V systems. It is suggested that innovative financing schemes and promotional campaigns should be devised.

Combined photovoltaic and solar-thermal systems: overcoming barriers to market acceptance

International Nuclear Information System (INIS)

Collins, M.R.

2005-01-01

Combined Photovoltaic and Solar-Thermal Systems (PV/T Systems) combine Photovoltaic (PV) and solar thermal technologies into one system with both electrical and thermal energy output. PV/T systems have several perceived advantages to stand-alone PV or solar-thermal systems. The increased efficiency and dual nature of the systems make suitable for situations where installation space is limited, and for homeowners who are forced to decide between meeting thermal or electrical needs. The financial benefit of the combined system is also significant, as the long payback of PV systems is joined with a relatively short payback of solar thermal systems. A background of PV/T was presented, with details of classifications and the International Energy Association's program to evaluate the technical status of PV/T systems and formulate a roadmap for future development. It was noted that input from the Solar Heating and Cooling Program (SHCP) is needed to help identify market barriers in PV/T systems. This paper reviewed existing and potential PV/T systems and their technical status, and reported on the methodology established by IEA group 35. The systems were grouped according to thermal collector types of unglazed water collectors, glazed water collectors, unglazed air collectors, glazed air collectors, air-flow windows, and concentrating collectors. It was noted that a number of new systems are currently being developed, including concentrating collectors with water and air heating, unglazed air heating systems, and unglazed water heating systems. It was noted that apart from technical barriers, efficient design and performance prediction are also problematic, as tools for predicting performance do not exist. The same tools will be used to optimize PV/T system designs. It was suggested that standardized reporting methods, simulation and sizing tools and demonstration products need to be created and that regional certification issues need to be identified.

Cucchiella, Federica; D’Adamo, Idiano; Gastaldi, Massimo

2016-01-01

Highlights: • Net Present Value varies from 437 to 624 € per kW installed. • Discounted Payback Time ranges from 4 years to 6 years. • Reduction of emissions of 21 tCO 2 eq for each kW installed during the 20 years. • Break-even point of increase of self-consumption varies from 6% to 13%. • The opportunity to keep a 50% of fiscal deduction for 5 years. - Abstract: The installation of photovoltaic power plants in 2015 compared to 2014 registered a growth of 25.6%, reaching a cumulative power equal to 229 GW. In developed solar markets, as many European countries, the sector is pushed by the alignment between the electric power demanded and the one offered. Consequently, self-consumption makes consumers active players of the energy transition. Italy is evaluated as a case study in this paper, in fact is the first country in the world where solar energy contributes largely to the national energetic demand. This paper aims to evaluate photovoltaic systems in residential sector without subsidies. Economic and environmental results are proposed and the indicators used are Net Present Value, Discounted Payback Time and Reduction in the Emissions of Carbon Dioxide. Three sizes (3 kW, 6 kW and 20 kW) are evaluated. In addition, a sensitivity analysis of critical variables (investment cost, annual electricity purchase price, annual electricity sales price, opportunity cost, tax deduction unitary, period of fiscal deduction, average annual insolation and percentage of energy self-consumption) demonstrates the robustness of the economic results. Also for environmental evaluation, alternative scenarios are proposed varying the value of emissions released by source energy analysed (photovoltaic, coal, oil and gas). Economic and environmental results suggest that small-scale photovoltaic systems can support the transition towards a sustainable energy mix.

Highlights of NASA/DOE photovoltaic market assessment visit to Morocco

Science.gov (United States)

1981-01-01

A broad range of agricultural, rural development, and other power applications in various regions of Morocco were examined to determine the potential market for photovoltaic products in Moroccan development. The primary focus of the study was the agriculture sector which accounts for approximately 17% of the country's GNP. The country has a clear need for reliable remote power systems, but does not have the financial resources to invest in the relatively high capital cost PV equipment. A modest potential for PV use was identified in nonagricultural rural services, such as refrigerators for rural clinics and rural radio-telephones. The main potential for PV in Morocco in the next five years lies mainly in the telecommunications sector. Applications include rural TV sets, TV repeater stations, microwave relay stations, and railroad, marine, and airline signalling. Market size estimates were derived from development and expansion plans. At an average customer cost for complete installed systems from $18/Wp to $30/Wp the total potential market value is estimated in the range of $6.6 to $11 million over the 1981-1986 period.

Solar Photovoltaics (PV) are solid state semiconductor electronic devices that transform infrared, visible, or ultraviolet light energy from the sun directly into electrical energy. Selenium was used to create the first solar cell in 1883. In 1954, Bell Laboratories developed the modern day silicon solar cell, whereby impurities were added to silicon through a process called doping. Silicon doped with boron results in a positive electrical charge, while silicon doped with phosphorous results in a negative electrical charge. The atom collision from photons in sunlight provides the necessary energy to free a trapped electron in the doped silicon, which then may flow through a wire creating an electric current. Many different materials besides silicon are used to create solar cells, such as plastics, organic compounds, and theoretically even special paints, while other doping agents besides boron and phosphorous are also used, such as arsenic and gallium. This paper provided an introduction to solar PV and world solar PV growth and markets. A review of solar PV economics was also included. In 2008, the total installed costs of solar photovoltaic cells were in the range of 7 to 10 Canadian dollars. In addition, the advantages and disadvantages of solar PV were presented. Solar technologies under research and development were also discussed and assessed. It was concluded that although solar PV was one of the most expensive forms of renewable generation, there is great potential for solar PV to gain broader based application as costs continue to drop. 11 refs., 1 tab., 1 fig.

The report provides a picture of the photovoltaic industry and its applications in France covering the years 1992 to end 2002. The main stream of photovoltaic (PV) activity in France is that of off-grid power systems. Nevertheless, the ADEME and other public authority partners decided in 1999 to contribute to the funding of grid-connected distributed photovoltaic power systems. During the year 2002, 3,4 MW of photovoltaic power systems were installed in France and its overseas departments. The annual off-grid PV power system market remains stable at around 2,4 MW per year and that of grid-connected distributed power systems reached almost 1 MW in 2002. The total cumulative installed PV power in France is 17 MW of which 15 MW are off-grid systems and 2 MW are grid-connected distributed PV power systems. This installed capacity represents the annual production of 15 GWh of electricity. The PV cell/module industry remains very active. The annual production of photovoltaic multi-crystalline silicon cells increased by 25 % during the year 2002 to reach 17 MW while the production of amorphous silicon thin film modules increased slightly to go over half a megawatt. Two French companies started introducing on the market photovoltaic modules specifically designed for building integration. Price of photovoltaic power systems is decreasing towards 20 euros per watt for off-grid systems under public funding and turnkey prices for grid-connected distributed PV power systems vary from 6 to 8 euros per watt according to the level of building integration. Business turnover of main companies covering the whole field of cell/module manufacturing and PV power system developers/installers, increased 18 % in 2002 to reach 130 million euros. Due to a Governmental decision taken in 1998, the ADEME increased its annual public budget for the promotion of PV in France to reach around 10 MEUR per year. This new measure allowed a) to reactivate the ADEME's research and technological

The global photovoltaic market expanded again in 2009. Germany set a new system installation record while the capacity build-up of the major solar photovoltaic markets contained the fallout generated by the Iberian market derailment. The European Union has the highest photovoltaic plant capacity, with almost 5.5 GWp installed in 2009. Italy is the third European Union country to pass the symbolic 1000 MWp installed mark, following Germany and Spain. France ranks 6 with 185 MWp installed in 2009. The decrease in the price of silicon reached 80% in 2009. The industry is facing a coming-of-age crisis with prices falling and over-production. Most of the major cell manufacturers are located in Asia. The European industry is still well represented with Q-Cells, the German leading cell manufacturer in addition with hefty industry players.

Meyer, Tim; Luther, Joachim

2004-01-01

Discussions about market introduction of grid connected photovoltaics (PV) and its costs usually concentrate only on the gross energy produced without taking the time dependency of electricity prices and, thus, the time dependency of the value of PV electricity into account. To make a first approximation of what the effect of the time variance of electricity cost on the value of PV electricity is, the correlation with spot market prices is analysed in this paper. PV is not dispatchable by nature, but is relatively well predictable in the range of one day, if the average of spatially dispersed systems is considered. Thus, this correlation gives a good indication for the additional value of PV electricity

The increasing demand for photovoltaic devices leads to the search for new developments with respect to material use and consumption, device design and production technologies, as well as new concepts to increase the overall efficiency. At present solar cell manufacturing is based on single junction device silicon wafer technology with close to 90% market share. Consistent with the time needed for any major change in the energy infrastructure, another 20 to 30 years of sustained and aggressive growth will be required for photovoltaic to substitute a significant share of the conventional energy sources. This growth will be possible if a continuous introduction of new technologies takes place, made possible by sound fundamental research. In October 2004 the Russian Duma ratified the Kyoto Protocol and it can be expected that the Protocol will now be set into force by the beginning of 2005. This recent development will definitively have an impact on the further implementation of renewable energies and photovoltaic is a prime source to deliver it. The Third Edition of the PV Status Report will widen its view to the enlarged European Union as well as the new player China and tries to give an overview about the current activities regarding Research, Manufacturing and Market Implementation. The opinion given in this report is based on the current information available to the author, and does not reflect the opinion of the European Commission. (author)

The author points out that although photovoltaics can be used for generating electricity for the same applications as many other means of generation, they really come into their own where disadvantages associated with an intermittent unpredictable supply are not severe. The paper discusses the advantages and disadvantages to be taken into account when considering a photovoltaic power system. Five main applications, based on the system features, are listed and explained. They are: consumer, professional, rural electrification, building-integrated, centralised grid connected and space power. A brief history of the applications of photovoltaics is presented with statistical data on the growth of installed capacity since 1992. The developing market for photovoltaics is discussed together with how environmental issues have become a driver for development of building-integrated photovoltaics

Full Text Available Solar energy is the most abundant, useful, efficient, and environmentally friendly source of renewable energy. In addition, in recent years, the capacity of photovoltaic electricity generation systems has increased exponentially throughout the world given an increase in the economic viability and reliability of photovoltaic systems. Moreover, many studies state that photovoltaic power systems will play a key role in electricity generation in the future. When first produced, photovoltaic systems had short lifetimes. Currently, through development, the technology lifecycle of photovoltaic systems has increased to 20–25 years. Studies showed that photovoltaic systems would be broadly used in the future, a conclusion reached by considering the rapidly decreasing cost of photovoltaic systems. Because price analysis is very important for energy marketing, in this study, a review of the cost potential factors on photovoltaic panels is realized and the expected cost potential of photovoltaic systems is examined considering numerous studies.

Recent developments in photovoltaics

Green, M.A.

The photovoltaic market is booming with over 30% per annum compounded growth over the last five years. The government-subsidised urban-residential use of photovoltaics, particularly in Germany and Japan, is driving this sustained growth. Most of the solar cells being supplied to this market are 'first generation' devices based on crystalline or multi-crystalline silicon wafers. 'Second generation' thin-film solar cells based on amorphous silicon/hydrogen alloys or polycrystalline compound semiconductors are starting to appear on the market in increasing volume. Australian contributions in this area are the thin-film polycrystalline silicon-on-glass technology developed by Pacific Solar and the dye sensitised nanocrystalline titanium cells developed by Sustainable Technologies International. In these thin-film approaches, the major material cost component is usually the glass sheet onto which the film is deposited. After reviewing the present state of development of both cell and application technologies, the likely future development of photovoltaics is outlined. (author)

Photovoltaics in Canada

Energy Technology Data Exchange (ETDEWEB)

Bolcso, S L

1983-06-01

A literature review was carried out for the purpose of summarizing the current conditions existing and affecting photovoltaics (PV) technology in a Canadian context. Information is presented concerning: PV device materials and efficiencies; PV cell manufacturing techniques; other materials/device designs; photovoltaic costs, markets, and research and development; PV and microelectronics; and Canadian strengths and opportunities. It was concluded that PV's simplicity, amenability to mass production and environmentally benign nature will likely assure it a faster and eventually greater market penetration than any other renewable energy form (and possibly some conventional forms). It is recommended that the Ministry of State, Science and Technology coordinate a joint microelectronics-photovoltaic research effort, by: indentifying areas where joint efforts would be mutually beneficial; identifying the strategic value of PV; identifying a set of goals for Canadian programs; coordinating efforts between government, universities and industry; developing supporting strategies for the mining and smelting of indigenous semiconducting materials; determining the economic support required to develop a silicon processing plant for the production of microelectronic chips and PV cells; developing Canadian expertise in providing complete PV systems competitive in world markets; and developing a marketing strategy for a coordinated PV/microelectronics effort. 60 refs., 17 figs., 12 tabs.

The photovoltaic industry has been growing with astonishing rates over the past years. The supply of silicon to the wafer-based industry has recently become a problem. This paper presents a thorough analysis of the PV industry and quantifies the silicon shortage. It is expected that this leads to a decrease in production in 2006 rather than the usual increase. Due to a mismatch in expansion plans of silicon feedstock manufacturers and solar cell manufacturers, a large cell overcapacity will persist up to 2010. The thin-film PV market is expected to profit from the silicon shortage problem; its market share may substantially increase to about 25% in 2010

Today, the silicon feedstock for photovoltaic cells comes from processes which were originally developed for the microelectronic industry. It covers almost 90% of the photovoltaic market, with mass production volume at least one order of magnitude larger than those devoted to microelectronics. However, it is hard to imagine that this kind of feedstock (extremely pure but heavily penalized by its high energy cost) could remain the only source of silicon for a photovoltaic market which is in continuous expansion, and which has a cumulative growth rate in excess of 30% in the last few years.

Japanese manufacturers' cost-performance marketing strategy for the delivery of solar photovoltaic homes

International Nuclear Information System (INIS)

Noguchi, M.

2005-02-01

Japanese manufacturers have been gaining a global reputation for their design approaches to industrialized housing, which is often equipped with PV systems. Homes are produced on a cost performance marketing strategy. In 2004, 13.7 per cent of the 1,160,083 houses built in Japan were pre-fabricated. The pre-fabricated housing industry has been given considerable government support. In response to growing demands for sustainable housing, the government has implemented promotional programs aiming to support the installations of photovoltaic systems. Details of various programs were presented, including: value-added production; housing sustainability; PV rooftop systems; and a mass custom design approach. It was concluded that the cost performance marketing strategy has a significant impact on production and design approaches. However, quality-oriented production may also result in successful commercialization of innovative housing. The Japanese marketing approach allows consumers to understand the added value of packaged innovations rather than the cost. It was suggested that this marketing strategy should be examined further, when considering approaches to innovative housing in other countries. 38 refs., 3 figs

Photovoltaic technology diffusion. Contact and interact

How can the diffusion of photovoltaic technologies be advanced? Photovoltaics convert light into electrical energy. They are environmentally friendly, reliable and have minimal maintenance requirements. Up to now, their introduction into the electricity market has been dominated by a technology push perspective. However, this has not yet resulted in a large-scale implementation. This thesis describes a network approach to advance photovoltaic diffusion and presents four guiding principles intended for the parties concerned: those who supply the photovoltaic technologies (e.g., developers of photovoltaic cells); those who integrate photovoltaic technologies into (new) product systems (e.g., engineering firms); the users of photovoltaic systems (e.g., housing corporations); and those who stimulate the use of photovoltaics (e.g., policymakers, subsidisers, branch organisations, financial institutes, and NGOs). refs

Combined photovoltaic and solar-thermal systems: overcoming barriers to market acceptance. Paper no. IGEC-1-136

In 1997, the International Energy Association's (IEA) Photovoltaic Power Systems Program (PVSP) initiated IEA Task 7 to evaluate the technical status of combined Photovoltaic and Solar-Thermal systems (PV/T), and to formulate a roadmap for future development. Because the Task was initiated by the PVSP, however, individuals from the Solar Heating and Cooling Program (SHCP) were not invited to participate, and the Task Group lacked any significant expertise with solar-thermal systems. When the Task submitted its final report in 2002, it consisted of an accounting of existing systems and a list of the perceived market barriers. Without input from the SHCP, however, no move could be made to actually address those barriers. IEA Task 7, however, did recognize that the participation of the SHCP was needed, and in 1999 made an effort to initiate some discussion between the PVSP and the SHCP. The result was IEA Task 35 - PV/T Systems, which met for the first time in January of 2005. The new group intends to reevaluate the findings of Task 7, and to develop the means by which these market barriers can be overcome. The current discussion will provide an overview of existing and potential PV/T systems and their technical status. Further, it will report on the methodology established by the Task 35 work group to overcome the aforementioned market barriers. (author)

Malaysia has identified photovoltaic systems as one of the most promising renewable sources. A great deal of efforts has been undertaken to promote the wide applications of PV systems. With the recent launch of a PV market induction programme known as SURIA 1000 in conjunction with other relevant activities undertaken under the national project of Malaysia Building Integrated Photovoltaic (MBIPV), the market of PV systems begins to be stimulated in the country. As a result, a wide range of technical, environmental and economic issues with regard to the connection of PV systems to local distribution networks becomes apparent. Numerous studies were therefore carried out in collaboration with Malaysian Energy Centre to address a number of those important issues. The findings of the studies are presented in the paper and can be served as supplementary information to parties who are directly and indirectly involved in the PV sector in Malaysia. (author)

This report examines the opportunities that will arise for the Australian photovoltaic industry if external costs of energy conversion are internalized. Such external costs include local pollution, resource depletion and the emission of greenhouse gases. Generation of electricity from photovoltaic (PV) modules is now a widely accepted environmentally friendly energy conversion technology. At present, high capital costs restricts its use to the provision of small amounts of power in remote areas, where it successfully competes against small diesel generators. However, as costs continue to decline, photovoltaic systems will compete successfully with progressively larger diesel-electric systems in Australia, in a market worth more than a billion dollars. Direct competition with electricity generated by conventional means for state grids is possible after the turn of the century. The present Australian photovoltaic industry is export oriented. The market for PV systems in poor rural areas in Asia is potentially very large. The cost of supplying small quantities of electricity to millions of rural households is high, making photovoltaics a competitive option. It is concluded that the Australian photovoltaic industry is in a good position to participate in the growth in this market sector. 48 refs., 28 tabs., 18 figs., ills

Japan has re-emerged in 2013 as one of the world's fastest-growing and largest photovoltaic (PV) markets (Renewable Energy World 2013). Year-over-year growth in Japanese installed capacity in the first half of 2013 was about 270%. Japan's PV market was on pace to triple in 2013 compared with 2012, with approximately 2.7 GW installed during the first half of 2013 (compared to about 1.6 GW in the United States). This places Japan's market among the world's largest PV markets, along with China, Germany, and the United States. This report explores details of the rapidly changing Japanese market, and similarities and differences between the Japanese and U.S. markets. We collected data from a diverse group of Japanese PV installers, and we gathered additional Japanese and U.S. data from published sources as well as internal analyses.

Japanese manufacturers' cost-performance marketing strategy for the delivery of solar photovoltaic homes

Energy Technology Data Exchange (ETDEWEB)

Noguchi, M.

2005-02-01

Japanese manufacturers have been gaining a global reputation for their design approaches to industrialized housing, which is often equipped with PV systems. Homes are produced on a cost performance marketing strategy. In 2004, 13.7 per cent of the 1,160,083 houses built in Japan were pre-fabricated. The pre-fabricated housing industry has been given considerable government support. In response to growing demands for sustainable housing, the government has implemented promotional programs aiming to support the installations of photovoltaic systems. Details of various programs were presented, including: value-added production; housing sustainability; PV rooftop systems; and a mass custom design approach. It was concluded that the cost performance marketing strategy has a significant impact on production and design approaches. However, quality-oriented production may also result in successful commercialization of innovative housing. The Japanese marketing approach allows consumers to understand the added value of packaged innovations rather than the cost. It was suggested that this marketing strategy should be examined further, when considering approaches to innovative housing in other countries. 38 refs., 3 figs.

The present commercial photovoltaic solar cells (PV) converts solar energy into electricity with a relatively low efficiency, less than 20%. More than 80% of the absorbed solar energy is dumped to the surroundings again after photovoltaic conversion. Hybrid PV/T systems consist of PV modules coupled with the heat extraction devices. The PV/T collectors generate electric power and heat simultaneously. Stabilizing temperature of photovoltaic modules at low level is highly desirable to obtain efficiency increase. The total efficiency of 60-80% can be achieved with the whole PV/T system provided that the T system is operated near ambient temperature. The value of the low-T heat energy is typically much smaller than the value of the PV electricity. The PV/T systems can exist in many designs, but the most common models are with the use of water or air as a working fuid. Efficiency is the most valuable parameter for the economic analysis. It has substantial meaning in the case of installations with great nominal power, as air-cooled Building Integrated Photovoltaic Systems (BIPV). In this paper the performance analysis of a hybrid PV/T system is presented: an energetic analysis as well as an exergetic analysis. Exergy is always destroyed when a process involves a temperature change. This destruction is proportional to the entropy increase of the system together with its surroundings the destroyed exergy has been called energy. Exergy analysis identifies the location, the magnitude, and the sources of thermodynamic inefficiencies in a system. This information, which cannot be provided by other means (e.g., an energy analysis), is very useful for the improvement and cost-effectiveness of the system. Calculations were carried out for the tested water-cooled ASE-100-DGL-SM Solar watt module.

Laborde, E.

The French photovoltaic industry counts two major players: Photowatt and Tenesol (formerly Total-energy). Specialized in distribution networks and systems engineering, Tenesol has recently become involved in assembling photovoltaic panels; it holds a strong position in its historical markets (France's overseas territories and departments). Photowatt, now celebrating its 30. birthday, is the only French manufacturer of solar wafers, cells and modules. It represents the core of France's photovoltaic industry. Although some small businesses are emerging in this sector, very few of them are involved in technological activities capable of achieving an industrial scale. For a long time, Photowatt has been leading the market and has even risen to number five worldwide. It is thriving thanks to niche markets (isolated sites, solar pumps) with public funding (national or international). (author)

Photovoltaic prospects in Europe

Science.gov (United States)

Starr, M. R.

The economics of solar cells is reviewed with an eye to potential cost reductions in processing, and potential markets are explored. Current solar cell systems costs are noted to be on the road to achieving the U.S. DoE goals of $0.40/kWp by 1990. Continued progress will depend on technical developments in cheaper materials and processes, scaling up production, and the success of sales programs. Various consumer and professional markets are outlined, with a prediction that a 12 MWp deman will be reached as a steady state by 1995. Photovoltaic panels may conceivably replace conventional roofing materials, resulting in the projection that, if grid-supplied power continues to inflate in price, then all new European homes would be equipped with photovoltaics by the year 2000. Further, accomplishment of the cost goals could generate a 1 GWp/yr industrial market at the same time.

Yin, Ershuai; Li, Qiang; Xuan, Yimin

2017-01-01

Highlights: • A detailed thermal resistance analysis of the PV-TE hybrid system is proposed. • c-Si PV and p-Si PV cells are proved to be inapplicable for the PV-TE hybrid system. • Some criteria for selecting coupling devices and optimal design are obtained. • A detailed process of designing the practical PV-TE hybrid system is provided. - Abstract: The thermal resistance theory is introduced into the theoretical model of the photovoltaic-thermoelectric (PV-TE) hybrid system. A detailed thermal resistance analysis is proposed to optimize the design of the coupled system in terms of optimal total conversion efficiency. Systems using four types of photovoltaic cells are investigated, including monocrystalline silicon photovoltaic cell, polycrystalline silicon photovoltaic cell, amorphous silicon photovoltaic cell and polymer photovoltaic cell. Three cooling methods, including natural cooling, forced air cooling and water cooling, are compared, which demonstrates a significant superiority of water cooling for the concentrating photovoltaic-thermoelectric hybrid system. Influences of the optical concentrating ratio and velocity of water are studied together and the optimal values are revealed. The impacts of the thermal resistances of the contact surface, TE generator and the upper heat loss thermal resistance on the property of the coupled system are investigated, respectively. The results indicate that amorphous silicon PV cell and polymer PV cell are more appropriate for the concentrating hybrid system. Enlarging the thermal resistance of the thermoelectric generator can significantly increase the performance of the coupled system using amorphous silicon PV cell or polymer PV cell.

Solar energy is an inexhaustible, clean, renewable energy source. Photovoltaic cells are a key component in solar power generation, so thorough research on output characteristics is of far-reaching importance. In this paper, an illumination model and a photovoltaic power station output power model were established, and simulation analysis was conducted using Matlab and other software. The analysis evaluated the condition of solar energy resources in the Baicheng region in the western part of Jilin province, China. The characteristic curve of the power output from a photovoltaic power station was obtained by simulation calculation. It was shown that the monthly average output power of the photovoltaic power station is affected by seasonal changes; the output power is higher in summer and autumn, and lower in spring and winter.

The global photovoltaic market expanded again in 2009. Germany set a new system installation record while the capacity build-up of the major solar photovoltaic markets contained the fallout generated by the Iberian market derailment. The European Union has the highest photovoltaic plant capacity, with almost 5.5 GWp installed in 2009. Italy is the third European Union country to pass the symbolic 1000 MWp installed mark, following Germany and Spain. France ranks 6 with 185 MWp installed in 2009. The decrease in the price of silicon reached 80% in 2009. The industry is facing a coming-of-age crisis with prices falling and over-production. Most of the major cell manufacturers are located in Asia. The European industry is still well represented with Q-Cells, the German leading cell manufacturer in addition with hefty industry players.

Photovoltaic policy is questioned

The French government has decided a freeze and a reassessment of the measures taken to support the photovoltaic sector. Only the installations with a power output over 3 kWc are concerned so the market of solar roofs for homes is spared. The main reasons for this reversal is the quick and chaotic development of photovoltaic projects, a lot of projects are only motivated by the lure of high purchase prices of the electricity produced imposed by the law on EDF. Another reason is that 90% of the solar panels installed in France come from China, the photovoltaic sector retorts that 75% of the price of a complete installation pays for services produced in France.

Solar photovoltaic (PV) system prices in the United States display considerable heterogeneity both across geographic locations and within a given location. Such heterogeneity may arise due to state and federal policies, differences in market structure, and other factors that influence demand and costs. This paper examines the relative importance of such factors on equilibrium solar PV system prices in the United States using a detailed dataset of roughly 100,000 recent residential and small commercial installations. As expected, we find that PV system prices differ based on characteristics of the systems. More interestingly, we find evidence suggesting that search costs and imperfect competition affect solar PV pricing. Installer density substantially lowers prices, while regions with relatively generous financial incentives for solar PV are associated with higher prices.

Algieri, Bernardina; Aquino, Antonio; Succurro, Marianna

2011-01-01

The present study aims at providing a comprehensive analysis of trade flows and the domestic value creation of the major solar photovoltaic industry at the world level. Solar technologies convert light and heat from the sun into useful energy. The use of the sun's energy can not only reduce the consumption of conventional fuels, thus reducing the emission of detrimental greenhouse gases, but it can also enable a gain in enhanced fuel and energy security along with lessening costs. In addition, green technologies and industries can promote economic growth and international competitiveness, and can offer new business and employment opportunities. It becomes, therefore, extremely important to deeply explore the dynamics of the solar photovoltaic sector. Specifically, the present work analyses the main global trends of this sector and sketches the key players on the world market, including producers, installers, and top traders. Based on an analysis of trade flows at the 6-digit level, the international specialisation patterns are investigated, and the role of various market and trade drivers, including subsidies in the uptake of solar technologies, is identified and examined. - Highlights: → Trade specialisation in solar photovoltaics is examined using an index analysis. → Trade of the US, UK and Germany has an intra-industry nature. → Trade of Italy, Greece and Japan is more inter-industry oriented. → There is a long-run relationship between PV exports, foreign income and prices.

Sizing and economic analysis of stand alone photovoltaic system with hydrogen storage

Science.gov (United States)

Nordin, N. D.; Rahman, H. A.

2017-11-01

This paper proposes a design steps in sizing of standalone photovoltaic system with hydrogen storage using intuitive method. The main advantage of this method is it uses a direct mathematical approach to find system’s size based on daily load consumption and average irradiation data. The keys of system design are to satisfy a pre-determined load requirement and maintain hydrogen storage’s state of charge during low solar irradiation period. To test the effectiveness of the proposed method, a case study is conducted using Kuala Lumpur’s generated meteorological data and rural area’s typical daily load profile of 2.215 kWh. In addition, an economic analysis is performed to appraise the proposed system feasibility. The finding shows that the levelized cost of energy for proposed system is RM 1.98 kWh. However, based on sizing results obtained using a published method with AGM battery as back-up supply, the system cost is lower and more economically viable. The feasibility of PV system with hydrogen storage can be improved if the efficiency of hydrogen storage technologies significantly increases in the future. Hence, a sensitivity analysis is performed to verify the effect of electrolyzer and fuel cell efficiencies towards levelized cost of energy. Efficiencies of electrolyzer and fuel cell available in current market are validated using laboratory’s experimental data. This finding is needed to envisage the applicability of photovoltaic system with hydrogen storage as a future power supply source in Malaysia.

A study was conducted to address the following strategic issues regarding the market development of photovoltaics (PV) in Canada: (1) to which type of market should PV products and services be promoted, (2) what is the level of demand for the various PV applications, (3) what constitutes quality and value to the users, (4) what barriers exist with respect to the use of PV technology, (5) which applications and product areas should be emphasized in the development, (6) what would be the best pricing strategy, (7) what types of financial incentives should be offered, and (8) what would be an effective promotional strategy. Information was collected via telephone discussions and was then transferred to an electronic database. The types of market that were included in this survey were remote homes and cottages, telecommunications, broadcasting, parks, and the oil and gas industry. The findings of the key applications for each of these market sectors were then presented. The applications varied from back-up power systems for houses, main household power systems for water pumping, lights and telephones, power supply at construction sites, and power supply for camping. The types of units available include stand-alone PV systems as well as PV-hybrid generators including PV-gas, or PV-diesel. A majority of participants in the survey suggested they would be willing to trade their existing generators for a PV or PV-hybrid system if it were offered at a reasonable price. PV/PV-hybrid systems are reliable, technologically proven, environmentally friendly, and offer a cost-effective fuel supply. tabs., figs.

An analysis of the technical exigencies and CE marking relative to low voltage (less than 5 kW) photovoltaic inverters marketed in Spain

Salas, V.; Olias, E.

2009-01-01

The objective of this article is to analyse the standards relative to technical exigencies and CE marking that correspond to photovoltaic inverters of low voltage (less than 5 kW) as marketed in Spain. For this study, around 400 different models of inverters from the European market were compiled. Twelve of them, 50 Hz single phase, were chosen, made up of different brands and options of transformer below 5 kW. For these inverters, regulations for each model were examined according to their data sheet specifications, manual and EC Declarations of Conformity. Heterogeneity in compliance to the standards was found. In addition, in view of results obtained it is possible to conclude that it would be wise to establish a common set of standards for every country in the world (or at least a common European normalization) according to PV grid inverters. It would enable all grid inverters to be commercialised in compliance with the same standards everywhere. (author)

Full Text Available There is no natural inertia in a photovoltaic (PV generator and changes in irradiation can be seen immediately at the output power. Moving cloud shadows are the dominant reason for fast PV power fluctuations taking place typically within a minute between 20 to 100% of the clear sky value roughly 100 times a day, on average. Therefore, operating a utility scale grid connected PV power plant is challenging. Currently, in many regions, renewable energy sources such as solar and wind receive feed-in tariffs that ensure a certain price for the energy. On the other hand, electricity markets operate on a supply-demand principle and a typical imbalance settlement period is one hour. This paper presents the energy, power and corresponding requirements for an energy storage system in a solar PV power plant to feed the power to the grid meeting the electricity spot markets practices. An ideal PV energy production forecast is assumed to be available to define reference powers of the system for the studied imbalance settlement periods. The analysis is done for three different PV system sizes using the existing irradiance measurements of the Tampere University of Technology solar PV power station research plant.

All of this activity is happening in the context of a new administration which supports accelerated development of environmental technologies. The DOE is committed to keeping this momentum alive to ensure US leadership in the growing photovoltaic market. The purpose of this paper is to give an update of the exciting progress and discuss ways to build on this momentum

Photovoltaics for Buildings Cutting-Edge PV

International Nuclear Information System (INIS)

Hayter, S. J.; Martin, R. L.

1998-01-01

Photovoltaic (PV) technology development for building-integrated applications (commonly called PV for Buildings) is one of the fastest growing areas in the PV industry. Buildings represent a huge potential market for photovoltaics because they consume approximately two-thirds of the electricity consumed in the US. The PV and buildings industries are beginning to work together to address issues including building codes and standards, integration, after-market servicing, education, and building energy efficiency. One of the most notable programs to encourage development of new PV-for-buildings products is the PV:BONUS program, supported by the US Department of Energy. Demand for these products from building designers has escalated since the program was initiated in 1993. This paper presents a range of PV-for-buildings issues and products that are currently influencing today's PV and buildings markets

Thin Films in the Photovoltaic Industry

International Nuclear Information System (INIS)

Jaeger-Waldau, A.

2008-03-01

In the past years, the yearly world market growth rate for Photovoltaics was an average of more than 40%, which makes it one of the fastest growing industries at present. Business analysts predict the market volume to increase to 40 billion euros in 2010 and expect rising profit margins and lower prices for consumers at the same time. Today PV is still dominated by wafer based Crystalline Silicon Technology as the 'working horse' in the global market, but thin films are gaining market shares. For 2007 around 12% are expected. The current silicon shortage and high demand has kept prices higher than anticipated from the learning curve experience and has widened the windows of opportunities for thin film solar modules. Current production capacity estimates for thin films vary between 3 and 6 GW in 2010, representing a 20% market share for these technologies. Despite the higher growth rates for thin film technologies compared with the industry average, Thin Film Photovoltaic Technologies are still facing a number of challenges to maintain this growth and increase market shares. The four main topics which were discussed during the workshop were: Potential for cost reduction; Standardization; Recycling; Performance over the lifetime.

In this article, our aim is to estimate the number of rural houses to be supplied with electricity by photovoltaic systems, using data from the national electric company in Tunisia (STEG) and the 1994 General Census. We also intent to estimate the electric consumption of three categories of houses, depending on the electrical appliances they own and on the annual hours of sunshine of the part of the country where they are situated. The estimated of the needed peak power is 15525 kWp to electrify 114,323 houses. (author)

Difficult marketing; Schwierige Vermarktung

Energy Technology Data Exchange (ETDEWEB)

Rentzing, Sascha

2013-02-15

With the new edition of the Renewable Energy Law (EEG) at 1st January 2012, the market premium model becomes effective in order to implement the green electricity into the electricity market better. With this, the operators of photovoltaic power plants switched from the fixed EEG compensation for electricity to direct marketing. The market premium model provides that only 90% of the power generated by large photovoltaic power plants on roofs of buildings are compensated via EEG corresponding to 0.15 Euro/kWh. The remaining 10% is compensated only with 0.045 Euro/kWh which complies with the actual stock exchange value. If one is not very happy with this solution, one has to consume the excess power by its own or to sell the excess power to third parties. The own consumption would be the easier solution. But the own consumption is usually not possible because the most large photovoltaic power plants are installed on roofs of commercial and public buildings. Consequently, the operators of these photovoltaic power plants have to sell the excess power to third parties. This is associated with many imponderables and additional costs.

Dupin, L.

2011-01-01

As the French government decided to reduce its financial support to photovoltaic energy, a first article identifies and comments the issues to be addressed to have a competitive French photovoltaic industry: to bet on second generation arrays (thin layer arrays), to have higher yearly objectives in terms of installed power (800 MW or 1 GW instead of 500 MW, in order to create a reference market), to redefine the financing and the electricity purchase scheme, to promote self consumption, to support exportation. The second article presents the first French photovoltaic test and certification centre, located near Chambery, where solar arrays are inspected and where their ageing is simulated through thermal fatigue and impact testing

1979-12-01

The International Photovoltaics Program Plan is in direct response to the Solar Photovoltaic Energy Research, Development, and Demonstration Act of 1978 (PL 95-590). As stated in the Act, the primary objective of the plan is to accelerate the widespread use of photovoltaic systems in international markets. Benefits which could result from increased international sales by US companies include: stabilization and expansion of the US photovoltaic industry, preparing the industry for supplying future domestic needs; contribution to the economic and social advancement of developing countries; reduced world demand for oil; and improvements in the US balance of trade. The plan outlines programs for photovoltaic demonstrations, systems developments, supplier assistance, information dissemination/purchaser assistance, and an informaion clearinghouse. Each program element includes tactical objectives and summaries of approaches. A program management office will be established to coordinate and manage the program plan. Although the US Department of Energy (DOE) had the lead responsibility for preparing and implementing the plan, numerous federal organizations and agencies (US Departments of Commerce, Justice, State, Treasury; Agency for International Development; ACTION; Export/Import Bank; Federal Trade Commission; Small Business Administration) were involved in the plan's preparation and implementation.

Perspectives of photovoltaic conversion development in the world

International Nuclear Information System (INIS)

Chiron, P.

2007-01-01

The present day economical context is favourable to the development of renewable energy sources: high fossil fuel prices, public awareness about environmental problems, etc. The incentive measures implemented by public authorities (regulation, repurchase tariff, tax credits etc.) have permitted to overcome the competitiveness handicap. This favorable framework should last long thanks to the strong support of the European Union. This market study deals with the photovoltaic conversion industry and answers the following questions: what is the world market growth of photovoltaic conversion? What are the most flourishing applications? What are the best oriented markets? How heavy is the world market? What is the degree of competitiveness of this industry? What is the development potential of this market? Who are the best-positioned groups to profit of it? What is the progress of the sector structuration? What is the future of pure players? (J.S.)

Drury, Easan; Miller, Mackay; Macal, Charles M.; Graziano, Diane J.; Heimiller, Donna; Ozik, Jonathan; Perry IV, Thomas D.

2012-01-01

Third-party photovoltaics (PV) ownership is a rapidly growing market trend, where commercial companies own and operate customer-sited PV systems and lease PV equipment or sell PV electricity to the building occupant. Third-party PV companies can reduce or eliminate up-front adoption costs, reduce technology risk and complexity by monitoring system performance, and can repackage the PV value proposition by showing cost savings in the first month of ownership rather than payback times on the order of a decade. We find that the entrance of third-party business models in southern California residential PV markets has enticed a new demographic to adopt PV systems that is more highly correlated to younger, less affluent, and less educated populations than the demographics correlated to purchasing PV systems. By enticing new demographics to adopt PV, we find that third-party PV products are likely increasing total PV demand rather than gaining market share entirely at the expense of existing customer owned PV demand. We also find that mean population demographics are good predictors of third-party and customer owned PV adoption, and mean voting trends on California carbon policy (Proposition 23) are poor predictors of PV adoption. - Highlights: ► Third-party PV products increased residential PV demand in southern CA. ► Third-party PV products entice new demographic groups to adopt PV. ► Regional demographics are good predictors of PV demand. ► Regional voting trends on carbon policy are poor predictors of PV demand.

Photovoltaic research and development in Japan

Science.gov (United States)

Shimada, K.

1983-01-01

The status of the Japanese photovoltaic (PV) R&D activities was surveyed through literature searches, private communications, and site visits in 1982. The results show that the Japanese photovoltaic technology is maturing rapidly, consistent with the steady government funding under the Sunshine Project. Two main thrusts of the Project are: (1) completion of the solar panel production pilot plants using cast ingot and sheet silicon materials, and (2) development of large area amorphous silicon solar cells with acceptable efficiency (10 to 12%). An experimental automated solar panel production plant rated at 500 kW/yr is currently under construction for the Sunshine Project for completion in March 1983. Efficiencies demonstrated by experimental large are amorphous silicon solar cells are approaching 8%. Small area amorphous silicon solar cells are, however, currently being mass produced and marketed by several companies at an equivalent annual rate of 2 MW/yr for consumer electronic applications. There is no evidence of an immediate move by the Japanese PV industry to enter extensively into the photovoltaic power market, domestic or otherwise. However, the photovoltaic technology itself could become ready for such an entry in the very near future, especially by making use of advanced process automation technologies.

Analysis of financial support for photovoltaic system installation with the economic simulation model

International Nuclear Information System (INIS)

Imamura, E.; Uchiyama, Y.

1994-01-01

The authors developed a penetration method of dispersed generation technologies and tried to investigate economic simulation on photovoltaic systems. The model is composed of several analysis modules; a technology application module, a regional meteorology module, cost modules such as capital cost, power generation cost, marginal cost and avoided cost, and a logistic penetration module. The database management system of application forms, meteorological data, energy demand and equipment costs is also developed to support the model. The main purpose of the study is to make clear impacts to the power supply configuration and cost/benefit effects when PV systems are installed into several different sectors in Japan. The ultimate potential of PV system is 235, 103MWp and its market potential is 15,172 MWp in Japan. Market penetration highly depends on cost learning factors of several components of PV system. The installed capacity with 50% subsidy is 5 times larger than that with 67%. In conclusion, it is feasible for government or utilities to financially support the promotion and installation of PV systems as the electricity supply system

Frantzis, L.; Hill, S.; Teagan, P.; Friedman, D.

1994-01-01

Arthur D Little, Inc., in conjunction with Solar Design Associates, conducted a study for the US Department of Energy (DOE), Office of Building Technologies (OBT) to determine the market potential for building-integrated photovoltaics (BIPV). This study defines BIPV as two types of applications: (1) where the PV modules are an integral part of the building, often serving as the exterior weathering skin, and (2) the PV modules are mounted on the existing building exterior. Both of these systems are fully integrated with the energy usage of the building and have potential for significant market penetration in the US

The internal rate of return of photovoltaic grid-connected systems. A comprehensive sensitivity analysis

International Nuclear Information System (INIS)

Talavera, D.L.; Nofuentes, G.; Aguilera, J.

2010-01-01

At present, photovoltaic grid-connected systems (PVGCS) are experiencing a formidable market growth. This is mainly due to a continuous downward trend in PV cost together with some government support programmes launched by many developed countries. However, government bodies and prospective owners/investors are concerned with how changes in existing economic factors - financial incentives and main economic parameters of the PVGCS - that configure a given scenario may affect the profitability of the investment in these systems. Consequently, not only is a mere estimate of the economic profitability in a specific moment required, but also how this profitability may vary according to changes in the existing scenario. In order to enlighten decision-makers and prospective owners/investors of PVGCS, a sensitivity analysis of the internal rate of return (IRR) to some economic factors has been carried out. Three different scenarios have been assumed to represent the three top geographical markets for PV: the Euro area, the USA and Japan. The results obtained in this analysis provide clear evidence that annual loan interest, normalised initial investment subsidy, normalised annual PV electricity yield, PV electricity unitary price and normalised initial investment are ordered from the lowest to the highest impact on the IRR. A short and broad analysis concerning the taxation impact is also provided. (author)

Building integrated concentrating photovoltaics: A review

International Nuclear Information System (INIS)

Chemisana, Daniel

2011-01-01

For building integration, Concentrating Photovoltaic (CPV) systems can offer a host of advantages over conventional flat panel devices, the most notable being: a higher electrical conversion efficiency in the PV cells, better use of space, ease of recycling of constituent materials, and reduced use of toxic products involved in the PV cells' production process. However, the viability of Building-Integrated Concentrating PV (BICPV) systems is dependent on their ability to offer a comparative economic advantage over flat panel photovoltaic technologies whose market prices are decreasing from day to day and which offer other advantages such as ease of replacement of structural elements. A comparative analysis is presented of the main existing CPV systems' suitability for use in buildings, in which the different challenges specific to integration of each system are discussed. The systems are categorized by type of concentration technology and concentration factor. (author)

Summary of third international executive conference on photovoltaic power systems

Energy Technology Data Exchange (ETDEWEB)

Gillett, W.

2001-07-01

In December 1990, the International Energy Agency (IEA) invited photovoltaic manufacturers, electrical utilities, and government leaders to a groundbreaking First Congress of Executives conference in Taormina, Italy. The purpose was to develop a strategic approach to PV market development. The Taormina Congress focused on the diffusion of applications based on cost-effectiveness. A second IEA International Conference was held in Sun Valley, Idaho, in September 1995, focusing on the implementation of physical markets based on profit opportunities. Discussions in Sun Valley included the integration of utility and PV businesses into new partnerships in the developing world. By 1995, the strategic interaction of utility activity with photovoltaic technology was recognised and a number of new business opportunities were identified in both industrialised and developing countries. The November 1999 conference, held in Venice, Italy, has taken things a step further. It focused on communicating the 'value of the sun', as well as bringing in the developing business interests and expanding roles of the building construction industries and finance institutions. This theme was considered as being the most important issue of the conference and led to the conclusion that just selling kilowatt-hours is not enough, as the market needs complete products and better concepts. Further, all of the relevant stakeholders, including PV industry, project developers, architects, local, regional and national governments, and the IEA should collaborate in a world-wide effort to accelerate the growth of markets for photovoltaic electricity. The conference was designed to provide a unique forum for senior executives from the energy and building sectors, the photovoltaic industry, financial institutions and governments. The aim was to discuss and jointly develop strategic business opportunities for photovoltaics in a rapidly changing energy market and to take the growing movement

International Nuclear Information System (INIS)

Serfass, J.A.; Wills, B.N.

1995-01-01

The Utility PhotoVoltaic Group (UPVG) was formed in October of 1992 with a mission to accelerate the use of cost-effective small-scale and emerging grid-connected applications of photovoltaics for the benefit of electric utilities and their customers. The UPVG is now implementing a program to install up to 50 megawatts of photovoltaics in small-scale and grid-connected applications. This program, called TEAM-UP, is a partnership of the US electric utility industry and the US Department of Energy to help develop utility PV markets. TEAM-UP is a utility-directed program to significantly increase utility PV experience by promoting installations of utility PV systems. Two primary program areas are proposed for TEAM-UP: (1) Small-Scale Applications (SSA)--an initiative to aggregate utility purchases of small-scale, grid-independent applications; and (2) Grid-Connected Applications (GCA)--an initiative to identify and competitively award cost-sharing contracts for grid-connected PV systems with high market growth potential, or collective purchase programs involving multiple buyers. This paper describes these programs and outlines the schedule, the procurement status, and the results of the TEAM-UP process

Moreira, J.G. de; Peri, G.

1990-01-01

The solar photovoltaic policy is taken into account in the great international market. Applying this high-technology, France encourages its industrial potentialities due to its former colonies closed market. This policy is enforced by CEE aids. The Paomia photovoltaic plant - 44 K W p - is the french CEE project. It is the principal European photovoltaic R and D programme. This plant originally unadapted to users' needs is now under used: on one side, because of its operational cost and on the other side, because of the arrival of the grid in this utilization area. Customers prefer at last the use of the conventional electricity for convenience sake. (author)

Smith, J. L.

1981-01-01

The federal government has sponsored a program of research and development on terrestrial photovoltaic systems that is designed to reduce the costs of such systems through technological advances. There are many potential paths to lower system costs, and successful developments have led to increased private investment in photovoltaics. The prices for photovoltaic collectors and systems that appear to be achievable within this decade offer hope that the systems will soon be attractive in utility applications within the United States. Most of the advances achieved will also be directly applicable to the remote markets in which photovoltaic systems are now commercially successful

Photovoltaic energy potential of Quebec

International Nuclear Information System (INIS)

Royer, J.; Thomas, R.

1993-01-01

Results are presented from a study concerning the potential of photovoltaic (PV) energy in Quebec to the year 2010. The different PV applications which are or will be economically viable in Quebec for the study period are identified and evaluated in comparison with the conventional energy sources used for these applications. Two penetration scenarios are proposed. One considers little change at the level of policies established for commercialization of PV sources, and the other considers certain measures which accelerate the implementation of PV technology in certain niches. While the off-grid market is already motivated to adopt PV technology for economic reasons, it is forecast that all encouragement from lowering costs would accelerate PV sales, offering a larger purchasing power to all interested parties. Above all, lowered PV costs would open up the network market. Photovoltaics would have access to a much larger market, which will accelerate changes in the very nature of the industry and bring with it new reductions in the costs of producing PV systems. 5 refs., 1 fig., 7 tabs

2003-01-01

Worldwide photovoltaic cell production increased 33.3% in 2002, and the European Union's installed capacity grew by 37.7% to reach 392 MWp. This dynamism remains however fragile, because the market, at least for a few more years, is still very closely linked to national programmes of grid-connected photovoltaic systems. Current hesitations in launching ambitious new programmes could seriously harm this industry, whose competitiveness is continually improving. (author)

1992-01-01

The Canadian Photovoltaic Industries Association (CPIA) conducted a survey among 65 Canadian firms involved in the photovoltaic industry and technology to determine the degree of commercial activity. Overall revenue for these firms in 1989 increased nearly 15% to ca $15 million. Actual reported sales of photovoltaic (PV) modules totalled 400 kW for use in Canada and abroad, of which communications applications accounted for ca 40% of these sales. Export sales were significant, with 59% of reported sales sold as packages being exported. Sales of systems within Canada were fairly evenly distributed between Quebec, Ontario, the Prairies, and British Columbia. The private sector share of reported sales was 42% or greater in terms of both dollar or peak wattage. Residential-use and water-pumping segments of the market reported increased activity. Internationally, annual PV module sales in 1989 were reported to be 42 MW peak, a 20% increase from 1988. The USA has the world market share with 36%, followed by Japan at 30%. Survey respondents made suggestions for more equitable tax treatment for PV products, and saw environmental issues as having a major impact on marketing strategies. 27 refs., 11 tabs

Almonacid, G.; Luque, A.; Molledo, A. G.

1984-12-01

Ray tracing is the basis of the present analysis of truncated bifacial compound parabolic concentrators filled with a dielectric substance, which are of interest in photovoltaic applications where the bifacial cells allow higher static concentrations to be achieved. Among the figures of merit for this type of concentrator, the directional intercept factor plays a major role and is defined as the ratio of the power of the collector to that at the entry aperture, in a lossless concentrator illuminated by light arriving from a given direction. A procedure for measuring outdoor, full size panels has been developed, and a correction method for avoiding the effect of unwanted diffuse radiation during the measurements is presented.

2009-01-01

This paper presents the possibility of using one of the renewable energy resources in agriculture. Specifically, the paper shows the possibility of converting solar energy into electricity through photovoltaic panels. The paper includes the analysis of the energy potential of solar radiation in the AP Vojvodina (Serbia). The results of the analysis can be used for the design of photovoltaic energy systems. The amount of solar energy on the territory of the province is compared with the same data from some European countries, in order to obtain a clear picture of the possibilities of utilization of this type of renewable sources. Three examples of possible application of photovoltaic systems are presented. The first relates to the consumer who is away from the electric distribution network - photovoltaic system in island mode. The remaining two examples relate to the application of photovoltaic power sources in manufacturing plants, flowers or vegetables. Applying photovoltaic source of electrical energy to power pumps for irrigation is highlighted

Based on an empirical analysis of different German wind power profiles from 2007 to mid-2012, we are able to show that the profitability significantly depends on the correlation of the wind power portfolio with the overall wind power feed-in and prediction error in Germany. Significant differences between the wind forecast errors clearing cost of the analyzed portfolios can be identified. Our analysis shows that a wind power operator would profit in most cases from a reduced forecast error, which could be achieved through an improved forecast model and an increased share of the intraday cleared error. Furthermore significant locational portfolio advantages and disadvantages can be identified when comparing the different market values. In general, the empirical analysis shows that a premium of 3.5 €/MWh is suitable to cover the cost of an imperfect forecast. Taking further into account that for 2012 a premium of 12 €/MWh was granted; the direct marketing option can be evaluated as highly attractive, which is furthermore indicated by the rapid increase of the directly marketed wind power and photovoltaic generation. - Highlights: • Wind power operator profitability in the German market premium model is analyzed. • Correlation with the overall wind power feed-in and prediction error is crucial. • Wind forecast error clearing cost of the analyzed portfolios show clear differences. • The direct marketing option of wind power can be evaluated as attractive.

The article discusses the reasons for the slow growth of the photovoltaic industry in Indonesia where more than 100 million people have no access to electricity, but there is an abundance of solar power. There should be considerable scope for solar home systems in particular. Barriers to expansion of the PV market have included the devaluation of the rupee and the failure of many government-initiated projects. It is concluded that at present, the purchasing power of individuals is insufficient for the potential PV market to expand

This review-paper focuses on the latest development of inverters for photovoltaic AC-Modules. The power range for these inverters is usually within 90 Watt to 500 Watt, which covers the most commercial photovoltaic-modules. Self-commutated inverters have replaced the grid-commutated ones. The same...... is true for the bulky low-frequency transformers versus the high-frequency transformers, which are used to adapt the voltage level. The AC-Module provides a modular design and a flexible behaviour in various grid conditions. It hereby opens the market for photovoltaic-power for everyone at a low cost due...

Photovoltaic energy systems have historically been treated as a bulk power generation source for the future. However, utilities and other agencies involved with electrification throughout the world are beginning to find photovoltaics a least-cost option to meet specific loads both for themselves and their customers, in both off-grid and grid-connected applications. These expanding markets offer the potential of hundreds of megawatts of sales in the coming decade, but a strategy addressing both industrial growth and user acceptance is necessary to capitalize on this opportunity. 11 refs

The most important assets of photovoltaic energy for sustainable development are its simplicity (no need for complicated thermodynamical cycles) and the universal availability of the sun which explains its great popularity. The main restraint to its full development is the high cost of the technologies used. The silicon technology is the historical technology, it has high conversion rates but is expensive because of high fabrication costs. This technology represents 80% of the market. On the other hand the thin film technology with CdTe, CIS or CIGS is promising in terms of costs but requires research works to increase its conversion rate. Japan and Germany are the leader countries in terms of photovoltaic for research, industrial fabrication or state support, they are followed by Spain, Usa, and China. (A.C.)

Photovoltaics is already a billion dollar industry. It is experiencing rapid growth as concerns over fuel supplies and carbon emissions mean that governments and individuals are increasingly prepared to ignore its current high costs. It will become truly mainstream when its costs are comparable to other energy sources. At the moment, it is around four times too expensive for competitive commercial production. Three generations of photovoltaics have been envisaged that will take solar power into the mainstream. Currently, photovoltaic production is 90% first-generation and is based on silicon wafers. These devices are reliable and durable, but half of the cost is the silicon wafer and efficiencies are limited to around 20%. A second generation of solar cells would use cheap semiconductor thin films deposited on low-cost substrates to produce devices of slightly lower efficiency. A number of thin-film device technologies account for around 5-6% of the current market. As second-generation technology reduces the cost of active material, the substrate will eventually be the cost limit and higher efficiency will be needed to maintain the cost-reduction trend. Third-generation devices will use new technologies to produce high-efficiency devices. Advances in nanotechnology, photonics, optical metamaterials, plasmonics and semiconducting polymer sciences offer the prospect of cost-competitive photovoltaics. It is reasonable to expect that cost reductions, a move to second-generation technologies and the implementation of new technologies and third-generation concepts can lead to fully cost-competitive solar energy in 10-15 years.

Accelerating residential PV expansion: demand analysis for competitive electricity markets

International Nuclear Information System (INIS)

Duke, Richard; Williams, Robert; Payne, Adam

2005-01-01

This article quantifies the potential market for grid-connected, residential photovoltaic (PV) electricity integrated into new homes built in the US. It complements an earlier supply-side analysis by the authors that demonstrates the potential to reduce PV module prices below $1.5/W p by scaling up existing thin-film technology in 100 MW p /yr manufacturing facilities. The present article demonstrates that, at that price, PV modules may be cost effective in 125,000 new home installations per year (0.5 GW p /yr). While this market is large enough to support multiple scaled up thin-film PV factories, inefficient energy pricing and demand-side market failures will inhibit prospective PV consumers without strong public policy support. Net metering rules, already implemented in many states to encourage PV market launch, represent a crude but reasonable surrogate for efficient electricity pricing mechanisms that may ultimately emerge to internalize the externality benefits of PV. These public benefits include reduced air pollution damages (estimated costs of damage to human health from fossil fuel power plants are presented in Appendix A), deferral of transmission and distribution capital expenditures, reduced exposure to fossil fuel price risks, and increased electricity system reliability for end users. Thus, net metering for PV ought to be implemented as broadly as possible and sustained until efficient pricing is in place. Complementary PV 'buydowns' (e.g., a renewable portfolio standard with a specific PV requirement) are needed to jumpstart regional PV markets

Community-scale solar photovoltaics: housing and public development examples

2008-03-15

This report for the International Energy Agency (IEA) made by Task 10 of the Photovoltaic Power Systems (PVPS) programme takes a look at community-scale photovoltaics. The mission of the Photovoltaic Power Systems Programme is to enhance the international collaboration efforts which accelerate the development and deployment of photovoltaic solar energy. The aim of Task 10 is stated as being to enhance the opportunities for wide-scale, solution-oriented application of photovoltaics in the urban environment. This report provides examples of housing developments and incorporated townships that have integrated multiple stakeholder values into business solutions. The authors are of the opinion that builders, developers, architects and engineers need to consider orientation, aesthetics, load diversity, energy efficiency, grid infrastructure and end use. Residential and commercial building owners or occupants need to consider the design of electric services relative to loads, green image, and economic opportunities such as feed-in tariffs. Local government should give preference to granting permission to high-performance building projects. It is suggested that the finance and insurance sector consider the operational savings in overall debt allowances. System manufacturers and integrators should develop standardised systems. In the emerging PV community market, utilities are quickly gaining awareness of business opportunities. The need for professionals and skilled labour is quoted as having grown as drastically as the PV market itself.

The global photovoltaic market has continued expanding despite the economic and financial crisis. Capacity in excess of 29000 MWp was connected in 2011 in the world, which is roughly 12200 MWp more than in 2010. The European Union (E.U.) is still the main hive of installation activity. It added more than 21500 additional MWp of capacity to the grid las year, and the 4 most important contributors to this added capacity are Italy with 9280 MWp, Germany with 7505 MWp, France with 1634 MWp and United Kingdom with 937 MWp. Outside the E.U., the surging Chinese, American and Japanese markets vouch for the enormous growth potential offered by solar power worldwide. When considering the photovoltaic power per inhabitant for each E.U. member in 2011, Germany ranks first with 304 Wp/inhabitant, Italy second with 210 Wp/inhabitant, Czech Republic third with 186 Wp/inhabitant, Belgium fourth with 165 Wp/inhabitant, the other countries are below 100 Wp/inhabitant. The sharp drop in the price of photovoltaic modules has led to a new rush on installations and most European countries reviewed their incentive system during first half 2012 in order to regain very firm control of the market. The price war started by Chinese and Taiwanese manufacturers may have delighted developers and investors, but it has sent the global photovoltaic industry into a self-destructive spiral. (A.C.)

Supply risks associated with CdTe and CIGS thin-film photovoltaics

Highlights: • Supply risks associated with thin film photovoltaic technologies are considered. • Eleven supply risk indicators are used to evaluate Cd, Te, Cu, In, Ga, Se and Mo. • Indicator weighting based on peer assessment and an Analytic Hierarchy Process. • Various possibilities for the aggregation of elemental supply risks discussed. • Aggregated results show a marginally lower supply risk for CdTe than for CIGS. - Abstract: As a result of the global warming potential of fossil fuels there has been a rapid growth in the installation of photovoltaic generating capacity in the last decade. While this market is dominated by crystalline silicon, thin-film photovoltaics are still expected to make a substantial contribution to global electricity supply in future, due both to lower production costs and to recent increases in conversion efficiency. At present, cadmium telluride (CdTe) and copper-indium-gallium diselenide (CuIn_xGa_1_−_xSe_2) seem to be the most promising materials and currently have a share of ≈9% of the photovoltaic market. An expected stronger market penetration by these thin-film technologies raises the question as to the supply risks associated with the constituent elements. Against this background, we report here a semi-quantitative, relative assessment of mid- to long-term supply risk associated with the elements Cd, Te, Cu, In, Ga, Se and Mo. In this approach, the supply risk is measured using 11 indicators in the four categories “Risk of Supply Reduction”, “Risk of Demand Increase”, “Concentration Risk” and “Political Risk”. In a second step, the single indicator values, which are derived from publicly accessible databases, are weighted relative to each other specifically for the case of thin film photovoltaics. For this purpose, a survey among colleagues and an Analytic Hierarchy Process (AHP) approach are used, in order to obtain a relative, element-specific value for the supply risk. The aggregation of these

China produces and exports about half of the photovoltaic cells made in the world. About 1000 Chinese enterprises work in the photovoltaic sector and the offer grows too fast to allow some enterprises to cope with lower and lower production costs. Research activities are a key element for the reduction of production costs but small companies can not usually sustain sufficient research. Economists foresee a strong reorganization of the sector: some enterprises will cease their photovoltaic activities, others will face financial difficulties, others will merge to make bigger companies. To make the demand bigger Chinese authorities are taking steps to develop the photovoltaic home market. The installed capacity of photovoltaic plants in China is expected to be somewhere between 11 GWc and 18 GWc in 2015, figures to be compared with only 0.9 GWc in 2010. (A.C.)

The spectacular growth of solar power based on solid industrial bases, makes photovoltaic one of the mainstays of global energy transition. In 2017, roughly 100 GW was installed worldwide, and just over half of that in China. The global market amounted to slightly less than half the European Union's installed base. The EU ended the year at 106.6 GW, i.e. 5.6 GW more than in 2016. While at just over 2% in 2017 solar photovoltaic output may still seem negligible on a global level, photovoltaic already supplies about 6% of the electricity mix in Japan, and more than 7% in Germany and Italy

Seawater pumping as an electricity storage solution for photovoltaic energy systems

Manfrida, Giampaolo; Secchi, Riccardo

2014-01-01

The stochastic nature of several renewable energy sources has raised the problem of designing and building storage facilities, which can help the electricity grid to sustain larger and larger contribution of renewable energy. Seawater pumped electricity storage is proposed as a good option for PV (Photovoltaic) or solar thermal power plants, located in suitable places close to the coast line. Solar radiation has a natural daily cycle, and storage reservoirs of limited capacity can substantially reduce the load to the electricity grid. Different modes of pump operation (fixed or variable speed) are considered, the preliminary sizing of the PV field and seawater reservoir is performed, and the results are comparatively assessed over a year-long simulated operation. The results show that PV pumped storage, even if not profitable in the present situation of the renewable energy Italian electricity market, is effective in decreasing the load on the transmission grid, and would possibly be attractive in the future, also in the light of developing off-grid applications. - Highlights: • A grid-connected seawater pumping system using photovoltaic power is proposed and its performance analyzed. • Year-round simulations are run with different sizes of photovoltaic field and reservoir. • An analysis is run about the profitability of the storage system, examining performance indexes and the cost of plant. • The system proposed appears near to attract the interest of the market

2010-01-01

Today, photovoltaic (PV) attracts considerable interest in relation to renewable energy technologies, because of its potential to contribute significantly to the future of renewable energy. However, PV market development is related strongly to the support policies introduced by national governments, defined in national laws. The modification or fading out of such incentive schemes can strongly influence the development of the PV market in any given country. In this paper, after a brief review of national support policies in PV technology in eastern European Union (EU) countries, the authors perform an economic analysis of the main support mechanisms that are implemented in these countries. The comparative analysis is based on the calculation of the cash flow, the Net Present Value (NPV) and the Internal Rate of Return (IRR) indices. The analysis shows that in some situations, support policies can be inconvenient for the owner of the PV system and that, in many cases, the differences between the implementation of the same support policy in different countries, can give rise to significantly different results.

The photovoltaic industry between growth and difficulties

International Nuclear Information System (INIS)

2013-01-01

This article proposes an overview of the situation and trends of the photovoltaic industry sector. If half of the market was shared among few German, Chinese and American companies in 2010, it appears that half of photovoltaic cells and arrays were designed and manufactured in China in 2013. The European Union and the USA therefore introduced taxes on these products. As this sector appears to be a strategic one, this resulted in a new support for this industry by the Chinese government. The article then comments the French market: slow development in terms of energy production as well as in terms of equipment manufacturing. Thus, measures taken by the French government resulted in a diversification of products, but cost of production of electricity remains high. Perspectives are finally evoked, notably in Japan after the Fukushima accident

According to a report by the French Renewable Energy Syndicate (SER), France had an installed photovoltaic fleet of 180 MW in late 2008, a substantial increase from 2007 (75 MW). This growth is largely due to the government's market-supporting policy that implemented a tax and tariff policy which encourages individuals to invest in so-called 'building integrated' systems; the goal of this policy is to bring together innovation in the building industry and the development of renewable energy among the French energy mix. The key event for the future of renewable energy and the photovoltaic sector in France was the 'Grenelle of the Environment'. This government initiative, launched in late 2007, became the subject of public debate and afterwards led to a bill which set the conditions under which France wishes to grow solar power's share of its energy mix. Working committees that bring together representatives from government authorities and industrial and public renewable energy stakeholders have proposed benchmarks. A few proposals with particular significance for photovoltaic power have been adopted by the government: - objectives for PV cumulative installed capacity in France of 1 100 MW in 2012 and 5 400 MW in 2020; - confirmation until 2012 of the current feed-in tariffs and the creation of an additional one targeting installations on large buildings such as commercial and industrial sheds. This tariff shall be set approximately at 0,45 EUR per kWh; - a call for tenders for the construction by 2011 of at least one solar photovoltaic power plant in each French region, for a total installed capacity of 300 MW. The nationally initiated actions for growing the market are heavily relayed by public assistance to regional councils, general councils, communities of communes and communes themselves, in accordance with their own particular specifications. The incentive to purchase electricity produced by built-in installations has caused a

Added values of photovoltaic power systems

International Nuclear Information System (INIS)

2001-03-01

The structure, ownership and operation of electricity systems around the world are changing in response to industry restructuring, the availability of new technologies and increasing environmental awareness. At the same time, many countries have yet to provide basic energy services for their populations, particularly in areas not served by the electricity grid. Large-scale, central power generation and distribution which characterized the electricity industry for much of the 20 th century is being challenged by new technologies, which are cleaner, faster to deploy and better matched to local requirements.

The structure, ownership and operation of electricity systems around the world are changing in response to industry restructuring, the availability of new technologies and increasing environmental awareness. At the same time, many countries have yet to provide basic energy services for their populations, particularly in areas not served by the electricity grid. Large-scale, central power generation and distribution which characterized the electricity industry for much of the 20{sup th} century is being challenged by new technologies, which are cleaner, faster to deploy and better matched to local requirements. Higher values are being placed on ancillary services, such as power system reliability and voltage stability, so that a simple comparison of energy cost is no longer appropriate as a measure of competitiveness. Solar photovoltaic electricity is unique amongst the new energy sources for the wide range of energy and non-energy benefits which can be provided, while the use of photovoltaic power systems as an integral part of a building provides the greatest opportunity for exploiting non-energy benefits and for adding value to the photovoltaic power system. This report documents the potential added values or non-energy benefits photovoltaic power systems can provide, the current state of market development and the key barriers faced by renewable energy technologies generally and photovoltaic power systems in particular. Means by which non-energy benefits may be used to overcome barriers to the use of photovoltaic power systems are then discussed, with specific attention to the use of building integrated photovoltaics.

Bidding Strategy of Virtual Power Plant with Energy Storage Power Station and Photovoltaic and Wind Power

Directory of Open Access Journals (Sweden)

Zhongfu Tan

2018-01-01

Full Text Available For the virtual power plants containing energy storage power stations and photovoltaic and wind power, the output of PV and wind power is uncertain and virtual power plants must consider this uncertainty when they participate in the auction in the electricity market. In this context, this paper studies the bidding strategy of the virtual power plant with photovoltaic and wind power. Assuming that the upper and lower limits of the combined output of photovoltaic and wind power are stochastically variable, the fluctuation range of the day-ahead energy market and capacity price is stochastically variable. If the capacity of the storage station is large enough to stabilize the fluctuation of the output of the wind and photovoltaic power, virtual power plants can participate in the electricity market bidding. This paper constructs a robust optimization model of virtual power plant bidding strategy in the electricity market, which considers the cost of charge and discharge of energy storage power station and transmission congestion. The model proposed in this paper is solved by CPLEX; the example results show that the model is reasonable and the method is valid.

2010-01-01

Within various renewable energy technologies, photovoltaics (PV) today attracts considerable attention due to its potential to contribute a major share of renewable energy in the future. However, PV market development is, undoubtedly, dependent on the political support of any given country. In this paper, after a brief analysis of national support policies in PV technology in western European Union (EU) countries, the authors perform an economic analysis of the main support mechanisms as implemented in the same countries, based on the calculation of the cash flow, the Net Present Value (NPV) and the Internal Rate of Return (IRR) indices. The analysis shows that in some situations support policies can be inconvenient for the owner of the PV-based generation system and that, in many cases, the differences between the implementation of the same support policy in different countries, can give rise to significantly different results. The analysis carried out in this work could help: ·to assess the impact of PV energy policies in different western European member states; ·renewable energy companies to identify potential PV markets and investigate the policy landscape across western EU countries.

SHADOW EFFECT ON PHOTOVOLTAIC POTENTIALITY ANALYSIS USING 3D CITY MODELS

Directory of Open Access Journals (Sweden)

N. Alam

2012-07-01

Full Text Available Due to global warming, green-house effect and various other drawbacks of existing energy sources, renewable energy like Photovoltaic system is being popular for energy production. The result of photovoltaic potentiality analysis depends on data quality and parameters. Shadow rapidly decreases performance of the Photovoltaic system and it always changes due to the movement of the sun. Solar radiation incident on earth's atmosphere is relatively constant but the radiation at earth's surface varies due to absorption, scattering, reflection, change in spectral content, diffuse component, water vapor, clouds and pollution etc. In this research, it is being investigated that how efficiently real-time shadow can be detected for both direct and diffuse radiation considering reflection and other factors in contrast with the existing shadow detection methods using latest technologies and what is the minimum quality of data required for this purpose. Of course, geometric details of the building geometry and surroundings directly affect the calculation of shadows. In principle, 3D city models or point clouds, which contain roof structure, vegetation, thematically differentiated surface and texture, are suitable to simulate exact real-time shadow. This research would develop an automated procedure to measure exact shadow effect from the 3D city models and a long-term simulation model to determine the produced energy from the photovoltaic system. In this paper, a developed method for detecting shadow for direct radiation has been discussed with its result using a 3D city model to perform a solar energy potentiality analysis.

Analysis of Electrical Characteristics of Thin Film Photovoltaic Cells

Solar energy is the most abundant form of energy in many terrestrial and extraterrestrial environments. Often in extraterrestrial environments sunlight is the only readily available form of energy. Thus the ability to efficiently harness solar energy is one of the ultimate goals in the design of space power systems. The essential component that converts solar energy into electrical energy in a solar energy based power system is the photovoltaic cell. Traditionally, photovoltaic cells are based on a single crystal silicon absorber. While silicon is a well understood technology and yields high efficiency, there are inherent disadvantages to using single crystal materials. The requirements of weight, large planar surfaces, and high manufacturing costs make large silicon cells prohibitively expensive for use in certain applications. Because of silicon s disadvantages, there is considerable ongoing research into alternative photovoltaic technologies. In particular, thin film photovoltaic technologies exhibit a promising future in space power systems. While they are less mature than silicon, the better radiation hardness, reduced weight, ease of manufacturing, low material cost, and the ability to use virtually any exposed surface as a substrate makes thin film technologies very attractive for space applications. The research group lead by Dr. Hepp has spent several years researching copper indium disulfide as an absorber material for use in thin film photovoltaic cells. While the group has succeeded in developing a single source precursor for CuInS2 as well as a unique method of aerosol assisted chemical vapor deposition, the resulting cells have not achieved adequate efficiencies. While efficiencies of 11 % have been demonstrated with CuInS2 based cells, the cells produced by this group have shown efficiencies of approximately 1 %. Thus, current research efforts are turning towards the analysis of the individual layers of these cells, as well as the junctions between

The sensitivity of the National Photovoltaic Research Program goals to changes in individual photovoltaic system parameters is explored. Using the relationship between lifetime cost and system performance parameters, tests were made to see how overall photovoltaic system energy costs are affected by changes in the goals set for module cost and efficiency, system component costs and efficiencies, operation and maintenance costs, and indirect costs. The results are presented in tables and figures for easy reference.

Built-in future: integration, technical and market-development issues for PV

International Nuclear Information System (INIS)

Nordmann, T.

2005-01-01

Although large ground-mounted multi-megawatt photovoltaic plants have become common, it is argued that integration of photovoltaics into the fabric of buildings is their optimum use. In Germany, with its well-established grid network, there is a marked imbalance in the deployment of photovoltaics and only 1% are integrated into the roofs or facades of buildings. A similar pattern is found in most other countries in central Europe and the article seeks to discover the reasons for this. The situation in Japan is different in that the relatively high cost of electricity has encouraged a robust market for domestic photovoltaics. It is argued that the market for building-integrated photovoltaics in Europe has massive potential

This paper contributes a critical view of the development of grid-connected photovoltaic systems (GCPVS) in Spain during the period 1998-2008 by looking into the different actions that were intended to promote this technology. The Spanish photovoltaic (PV) sector has undergone bullish development in the recent years, but its underlying factors still lack systematic identification and analysis. Accordingly, this paper collects and presents detailed data for describing this evolution. It also makes a special case of the particular promotion of PV systems on roof and goes further to analyze how these actions have affected GCPVS evolution as well as the magnitude of their impact on its performance. The exponential growth of installed cumulative PV power at the end of this period, which largely exceeded the target set for 2008, is canvassed by building an analogy with feedback control systems. In this approach, market response or the PV power attained is considered as the system output, while the different regulation changes are regarded as control actions aimed at enabling GCPVS to hit the energy target. Such an analysis allows determining the most significant delays and control actions that explain the system's performance. Hence, this study suggests an alternative framework to support the formulation and assessment of energy policy as it puts the emphasis not only on the evolution of the system per se but rather on the performance of the system against the energy target. In this regard, it might contribute to enhance the promotion mechanisms of green technologies. (author)

Integration of Photovoltaics in Buildings—Support Policies Addressing Technical and Formal Aspects

Directory of Open Access Journals (Sweden)

Thorsten Schuetze

2013-06-01

Full Text Available The integration of photovoltaic (PV generators in the envelope of a building by means of building-integrated photovoltaics (BIPV offers an immense potential, both in market development and the production of renewable electric energy that is close to the point of electricity consumption. In Germany, for example, by integrating photovoltaics in buildings up to 50% of the electricity demand can be covered. The political support of BIPV would contribute to the development and installation of BIPV components and therefore also promote the development of new business areas for industries dealing with components used in building envelopes and photovoltaic generators. BIPV can be separated into three different integration types: “technical”, “formal” and “technical & formal”. Political instruments for the support of PV-installations, particularly BIPV are discussed in this paper using Germany and France as examples. Due to successful financial support policies, PV became the most powerful electricity production technology in Germany. In France, the unique financial support of BIPV is resulting in an exemplary development and growth of certified BIPV components available on the market and, from a technical, aesthetic architectural and legal certainty point of view, facilitating the easy and widespread integration of photovoltaic generators in buildings.

Photovoltaic (PV) technology is now sufficiently advanced that market support mechanisms such as net metering plus a renewable portfolio standard (RPS) could induce rapid PV market growth in grid-connected applications. With such support mechanisms, markets would be sufficiently large that manufacturers could profitably build and operate 100 MW p /yr PV module factories, and electricity costs for residential rooftop PV systems would compare favorably with residential electricity prices in certain areas (e.g., California and the greater New York region in the US). This prospect is illustrated by economic and market analyses for one promising technology (amorphous silicon thin-film PV) from the perspectives of both module manufacturers and buyers of new homes with rooftop PV systems. With public policies that reflect the distributed and environmental benefits offered by PV-and that can sustain domestic PV market demand growth at three times the historical growth rate for a period of the order of two decades - PV could provide 3% of total US electricity supply by 2025.

The overall power of installed PV systems in France in 2007 was 31,3 MW which represents a significant growth compared to 2006. This increase is mainly due to the national fiscal measures (new feed-in tariff and tax credit) launched in 2006. The implemented feed-in tariff model application supports building integration of photovoltaic generators with a much higher financial incentive than other type of photovoltaic installations. In the same way, local authorities like regional councils and departmental councils developed new policies to promote photovoltaics through specific grants. As the building integration of photovoltaic generators is encouraged by a feed-in tariff bonus, innovative products are appearing on the market or are under development. In parallel, actors like architects, designers, engineers are now paying attention to building integration of photovoltaic components (BIPV). New actors such as financial institutions, energy operators, and private investors have developed ambitious projects. With the increase of the market, new firms have been created including engineering, consultancies, electricity producers, PV products distributors and retailers, installation and maintenance companies. Photovoltaic industrial sector is getting stronger and large investments have been undertaken in order to develop a vertical integration of the photovoltaic value chain, from feedstock silicon production to final photovoltaic products. A new private-public consortium called 'PV Alliance Lab Fab' has been set up and an important R and D project under the name of 'Solar Nano Crystal' should start by the end of 2008. At the same time, R and D activities focus on photovoltaic silicon cells/modules conversion efficiency and long term reliability, production costs, new materials and device design, yield, environmental impact of industrial processes and optimisation of control and monitoring of photovoltaic systems.

Concentrated photovoltaic (PV) technology represents a growing market in the field of terrestrial solar energy production. As the demand for renewable energy technologies increases, further importance is placed upon the modeling, design, and simulation of these systems. Given the U.S. Air Force cultural shift towards energy awareness and conservation, several concentrated PV systems have been installed on Air Force installations across the country. However, there has been a dearth of research within the Air Force devoted to understanding these systems in order to possibly improve the existing technologies. This research presents a new model for a simple concentrated PV system. This model accurately determines the steady state operating temperature as a function of the concentration factor for the optical part of the concentrated PV system, in order to calculate the optimum concentration that maximizes power output and efficiency. The dynamic thermal model derived is validated experimentally using a commercial polysilicon solar cell, and is shown to accurately predict the steady state temperature and ideal concentration factor.

The French photovoltaic industry counts two major players: Photowatt and Tenesol (formerly Total-energy). Specialized in distribution networks and systems engineering, Tenesol has recently become involved in assembling photovoltaic panels; it holds a strong position in its historical markets (France's overseas territories and departments). Photowatt, now celebrating its 30. birthday, is the only French manufacturer of solar wafers, cells and modules. It represents the core of France's photovoltaic industry. Although some small businesses are emerging in this sector, very few of them are involved in technological activities capable of achieving an industrial scale. For a long time, Photowatt has been leading the market and has even risen to number five worldwide. It is thriving thanks to niche markets (isolated sites, solar pumps) with public funding (national or international). (author)

This comprehensive description and discussion of photovoltaics (PV) is presented at a level that makes it accessible to the interested academic. Starting with an historical overview, the text outlines the relevance of photovoltaics today and in the future. Then follows an introduction to the physical background of solar cells and the most important materials and technologies, with particular emphasis placed on future developments and prospects. The book goes beyond technology by also describing the path from the cell to the module to the system, proceeding to important applications, such as grid-connected and stand-alone systems. The composition and development of the markets and the role of PV in future energy systems are also considered. Finally, the discussion turns to the future structure of energy supplies, expected to comprise more distributed generation, and addresses synergies and competition from other carbon-free energy sources.

Sevilla-Camacho, P.Y.; Robles-Ocampo, J.B.; Zuñiga-Reyes, Marco A.

2017-01-01

This research work presents a method to detect the number of short circuit faulted solar photovoltaic modules in strings of a photovoltaic system by taking into account speed, safety, and non-use of sensors and specialized and expensive equipment. The method consists on apply the spectral analysis and statistical techniques to the alternating current output voltage of a string and detect the number of failed modules through the changes in the amplitude of the component frequency of 12 kHz. For that, the analyzed string is disconnected of the array; and a small pulsed voltage signal of frequency of 12 kHz introduces him under dark condition and controlled temperature. Previous to the analysis, the signal is analogic filtered in order to reduce the direct current signal component. The spectral analysis technique used is the Fast Fourier Transform. The obtained experimental results were validated through simulation of the alternating current equivalent circuit of a solar cell. In all experimental and simulated test, the method allowed to identify correctly the number of photovoltaic modules with short circuit in the analyzed string. (author)

Full Text Available Sun is the most important source of renewable source of energy. During the past few decades there has been an ever-increasing interest in Photovoltaic (PV cells as it directly converts solar radiation into electricity. This paper involves the performance study of photovoltaic system under concentrated solar radiation. The main problem with the concentration solar energy is the drastic increase in temperature of the photovoltaic module resulting in a decrease in performance efficiency of the system. This problem of overheating of the system can be overcome by providing cooling which would ensure operation of the module in the optimal temperature range. Hence, the setup would function as a hybrid model serving the dual purpose of power generation while also utilizing the waste heat for water heating applications. The experimental set up consist of a novel arrangement of concentrator and reflector and the cooling system. The Hybrid Photovoltaic System was repeatedly tested under real time conditions on several days. A comparison was drawn between the results obtained from direct exposure of a standard photovoltaic module to that obtained from the hybrid system in order to better understand the improvement in performance parameters. The study shown a significant improvement of output of standard photovoltaic module under the concentrated solar radiation.

McConnell, R.; Symko-Davies, M.

2006-05-01

Multijunction solar cells provide high-performance technology pathways leading to potentially low-cost electricity generated from concentrated sunlight. The National Center for Photovoltaics at the National Renewable Energy Laboratory has funded different III-V multijunction solar cell technologies and various solar concentration approaches. Within this group of projects, III-V solar cell efficiencies of 41% are close at hand and will likely be reported in these conference proceedings. Companies with well-developed solar concentrator structures foresee installed system costs of $3/watt--half of today's costs--within the next 2 to 5 years as these high-efficiency photovoltaic technologies are incorporated into their concentrator photovoltaic systems. These technology improvements are timely as new large-scale multi-megawatt markets, appropriate for high performance PV concentrators, open around the world.

International Nuclear Information System (INIS)

Sivaraman, Deepak; Horne, Ralph E.

2011-01-01

The last decade has seen significant innovation and change in regulatory incentives to support photovoltaic deployment globally. With high fossil fuel dependency and abundant solar resource availability in Australia, grid connected photovoltaics are a viable low carbon technology option in existing electricity grids. Drawing on international examples, the potential to increase grid PV deployment through government response and regulation is explored. For each renewable energy certificate (REC) earned by small scale photovoltaics until 2012, the market provides four additional certificates under the current banded renewable targets. Our analysis indicates that REC eligibility is not accurately estimated currently, and an energy model is developed to calculate the variance. The energy model estimates as much as 26% additional REC's to be obtained by a 3 kWp PV system, when compared to the currently used regulatory method. Moreover, the provision of REC's increases benefits to PV technologies, in the process distorting CO 2 abatement (0.21 tonne/REC) by 68%, when PV displaces peaking natural gas plants. Consideration of the secondary effects of a banded structure on emissions trading market is important in the context of designing a range of initiatives intended to support a transition to a low carbon electricity sector. - Research Highlights: →Grid connected photovoltaics hedge spikes in peak demand summer electricity prices. →Nationwide feed in tariff and new building regulations needed to increase PV deployment. →Australia has transitioned from a solar rebate to a banded solar credit structure. →The currently used regulatory deeming method underestimates REC eligibility by 27%. →The banded structure can potentially distort CO 2 abatement by as much as 68%.

This report for the International Energy Agency (IEA) made by Task 10 of the Photovoltaic Power Systems (PVPS) programme takes a look at urban photovoltaic electricity policies. The mission of the Photovoltaic Power Systems Programme is to enhance the international collaboration efforts which accelerate the development and deployment of photovoltaic solar energy as a significant and sustainable renewable energy option. The objective of Task 10 is stated as being to enhance the opportunities for wide-scale, solution-oriented application of photovoltaics in the urban environment. The goal of the study presented was to evaluate a standardised basis for urban policies regarding photovoltaic integration in a set of cities in the countries participating in the IEA's Task 10, Urban Scale PV. The investigation was focused on three topics: the present state of the policies, the prospects for future policies fostering photovoltaic deployment and the prospects for future policies to cope with large-scale photovoltaic integration. The first section analyses the state of the policies; this analysis is then confirmed in section 2, which deals with present obstacles to PV deployment and solutions to overcome them. The third section investigates future prospects for PV deployment with the question of mastering large scale integration. The report concludes that cities could formulate urban solutions by developing integrated, specific provisions for PV deployment in their urban infrastructure planning.

Everybody agrees that there is a bright future for solar energy. After two decades of research and development, the market introduction of solar hot water systems is now taking off. In several countries, including the Netherlands, preparations are also underway for the large-scale introduction of photovoltaic systems. Although the share of thermal and photovoltaic solar energy in the energy supply sector in the Netherlands is very small (0.1 PJ) there are signs of imminent change. According to the Follow-up Policy Document on Energy Conservation, the share of solar energy should increase to 7 PJ by the year 2010. After years of concentrating on research and development, it is now generally recognised that it is time to introduce these technologies onto the market in order to realize the long-term objectives. In this respect, thermal solar energy is ahead of photovoltaics. 4 ills

1994-12-01

Energy is a critical factor which determines the progress of rural development. Energy is therefore an area of concern. The quality, availability and cost of conventional energies, plus the associated environmental effects are a growing problem - not only for the health infrastructure but also for agriculture and domestic life. This is true not only in developing countries where the fast growing industries and urban populations demand a soaring proportion of available energy at the expense of the rural communities, but also in the poorest countries with weak energy infrastructure. Renewable energies, much studied in the last 20 years, can meet the needs of rural health and education services and communities by providing high quality, low cost, non-polluting energy. Solar energy, in particular, has the flexibility to produce electricity, heat and cooling. Solar technologies, furthermore, are backed by an established and experienced industry. This report proposes to meet the energy needs for health and education in rural communities. This report analyses the need and market for photovoltaic Mini Power Plants in the 1-20 kW size. According to WHO and UNESCO such plants will be able to fulfill the requirements in rural community villages, health centres and education centres and be economically feasible. (au)

Can photovoltaic replace nuclear?

International Nuclear Information System (INIS)

2017-01-01

As the French law on energy transition for a green growth predicts that one third of nuclear energy production is to be replaced by renewable energies (wind and solar) by 2025, and while the ADEME proposes a 100 per cent renewable scenario for 2050, this paper proposes a brief analysis of the replacement of nuclear energy by solar photovoltaic energy. It presents and discusses some characteristics of photovoltaic production: production level during a typical day for each month (a noticeable lower production in December), evolution of monthly production during a year, evolution of the rate between nuclear and photovoltaic production. A cost assessment is then proposed for energy storage and for energy production, and a minimum cost of replacement of nuclear by photovoltaic is assessed. The seasonal effect is outlined, as well as the latitude effect. Finally, the authors outline the huge cost of such a replacement, and consider that public support to new photovoltaic installations without an at least daily storage mean should be cancelled

The French government has decided a freeze and a reassessment of the measures taken to support the photovoltaic sector. Only the installations with a power output over 3 kWc are concerned so the market of solar roofs for homes is spared. The main reasons for this reversal is the quick and chaotic development of photovoltaic projects, a lot of projects are only motivated by the lure of high purchase prices of the electricity produced imposed by the law on EDF. Another reason is that 90% of the solar panels installed in France come from China, the photovoltaic sector retorts that 75% of the price of a complete installation pays for services produced in France.

Development of a general method for photovoltaic system analysis

Energy Technology Data Exchange (ETDEWEB)

Nolay, P

1987-01-01

The photovoltaic conversion for energetic applications is now widely used, but its development still needs the resolution of many problems for the sizing and for the real working of the installations. The precise analysis of the components and whole system behaviour has led to the development of accurate models for the simulation of such systems. From this modelling phase, a simulation code has been built. The validation of this software has been achieved from experimental test measurements. Since the quality of the software depends on the precision of the input data, an original method of determination of component characteristics, by means of model identification, has been developed. These tools permit the prediction of system behaviour and the dynamic simulation of systems under real conditions. Used for the study of photovoltaic system sizing, this software has allowed the definition of new concepts which will serve as a basis for the development of a sizing method.

International collaboration can be leveraged to accelerate the innovation and diffusion of low carbon technologies required to realize the shift to a low carbon trajectory. A collaborative approach to innovation has the potential to capture several benefits, including: pooling risks and achieving scale; knowledge sharing that accommodates competition and cooperation; the creation of a global market; facilitation of policy learning and exchange; and the alignment of technology, finance and policy. International Collaboration: the Virtuous Cycle of Low Carbon Innovation and Diffusion An Analysis of Solar Photovoltaic, Concentrating Solar Power and Carbon Capture and Storage A range of obstacles to the diffusion of low carbon technologies provides ample opportunity for international collaboration in global market creation and capacity building, expanding beyond conventional modes of technology transfer. Current collaborative efforts for carbon capture and storage, solar photovoltaic and concentrating solar power technologies are active in all stages of innovation and diffusion and involve a wide range of actors. Yet, current efforts are not sufficient to achieve the necessary level of emission mitigation at the pace required to avoid catastrophic levels of atmospheric destabilization. This analysis sets forth recommendation to scale up current endeavors and create new ones. The analysis begins by describing the fundamental characteristics of innovation and diffusion processes that create opportunities for international collaboration. It then illustrates a broad array of on-going collaborative activities, depicting how these efforts contribute to innovation and diffusion. Finally, highlighting the gap between the current level of collaborative activities and technology targets deemed critical for emission mitigation, the report sets forth several recommendations to build on current efforts and construct new endeavors

The massive growth of photovoltaics (PV) challenges the German electricity supply system. It is necessary to adjust the generation of electricity from PV to the demand, to prevent power grid overloads due to solar electricity and to integrate the electricity into the market. This thesis examines, how decentralised energy storage devices can contribute to overcome these challenges and to what extent this approach is promoted by the current legal framework. It shows, that decentralised energy storage devices could contribute to the system und market inte-gration of PV, but the legal incentives are insufficient to realise this potential.

The significant research interest in the engineering of photovoltaic (PV) structures at the nanoscale is directed toward enabling reductions in PV module fabrication and installation costs as well as improving cell power conversion efficiency (PCE). With the emergence of a multitude of nanostructured photovoltaic (nano-PV) device architectures, the question has arisen of where both the practical and the fundamental limits of performance reside in these new systems. Here, the former is addressed a posteriori. The specific challenges associated with improving the electrical power conversion efficiency of various nano-PV technologies are discussed and several approaches to reduce their thermal losses beyond the single bandgap limit are reviewed. Critical considerations related to the module lifetime and cost that are unique to nano-PV architectures are also addressed. The analysis suggests that a practical single-junction laboratory power conversion efficiency limit of 17% and a two-cell tandem power conversion efficiency limit of 24% are possible for nano-PVs, which, when combined with operating lifetimes of 10 to 15 years, could position them as a transformational technology for solar energy markets.

Applicable uses and the market size for photovoltaic (PV) systems were investigated taking into consideration the features and economics of such systems. As a result of computing representative usage examples together with the extent of potential demand for PV, 238 GW for the power source in private homes, 76 GW for green houses, 126 GW for sewage water treatment plants, 4 GW for schools and universities and others were estimated. For the greater number of PV systems already in actual use, non-cost factors acted as major determining factors when deciding on implementation. Promising uses (applicable ideas) seen from the standpoint of non-cost factors were studied in order to develop the PV system market and gain breakthrough for lowering future costs and increasing proliferation for such systems. When it comes to simultaneously decreasing costs and increasing demand for solar batteries in the coming days, it will be impossible to make an immediate transition from the present state of demand for public use and for special use to the final goal of demand as a power source in the home. There is a need for an intermediate demand that can bridge this gap. (13 figs, 9 tabs)

Electrical Rating of Concentrated Photovoltaic (CPV) Systems: Long-Term Performance Analysis and Comparison to Conventional PV Systems

2016-02-29

The dynamic nature of meteorological data and the commercial availability of diverse photovoltaic systems, ranging from single-junction silicon-based PV panels to concentrated photovoltaic (CPV) systems utilizing multi-junction solar cells and a two-axis solar tracker, demand a simple but accurate methodology for energy planners and PV system designers to understand the economic feasibility of photovoltaic or renewable energy systems. In this paper, an electrical rating methodology is proposed that provides a common playing field for planners, consumers and PV manufacturers to evaluate the long-term performance of photovoltaic systems, as long-term electricity rating is deemed to be a quick and accurate method to evaluate economic viability and determine plant sizes and photovoltaic system power production. A long-term performance analysis based on monthly and electrical ratings (in kWh/m2/year) of two developed CPV prototypes, the Cassegrain mini dish and Fresnel lens CPVs with triple-junction solar cells operating under the meteorological conditions of Singapore, is presented in this paper. Performances are compared to other conventional photovoltaic systems.

The National Photovoltaic Program supports efforts to make PV an important part of the US economy through three main program elements: Research and Development, Technology Development, and Systems Engineering and Applications. (1) Research and Development activities generate new ideas, test the latest scientific theories, and push the limits of PV efficiencies in laboratory and prototype materials and devices. (2) Technology Development activities apply laboratory innovations to products to improve PV technology and the manufacturing techniques used to produce PV systems for the market. (3) Systems Engineering and Applications activities help improve PV systems and validate these improvements through tests, measurements, and deployment of prototypes. In addition, applications research validates, sales, maintenance, and financing mechanisms worldwide. (4) Environmental, Health, Safety and Resource Characterization activities help to define environmental, health and safety issues for those facilities engaged in the manufacture of PV products and organizations engaged in PV research and development. All PV Program activities are planned and executed in close collaboration and partnership with the U.S. PV industry. The overall PV Program is planned to be a balanced effort of research, manufacturing development, and market development. Critical to the success of this strategy is the National Photovoltaic Program`s effort to reduce the cost of electricity generated by photovoltaic. The program is doing this in three primary ways: by making devices more efficient, by making PV systems less expensive, and by validating the technology through measurements, tests, and prototypes.

Analysis of internal shading degree to a prototype of dynamics photovoltaic greenhouse through simulation software

Directory of Open Access Journals (Sweden)

Alvaro Marucci

2015-12-01

Full Text Available In recent years the use of photovoltaic panels as cover materials for greenhouses developed a great interest due to the state’s incentives obtainable by such applications. Shading caused by these elements inside the structure appears to be often too much for the normal development of agricultural activity. In this study it was analyzed the behaviour of shading caused by the photovoltaic panels inside a prototype of dynamic photovoltaic greenhouse whose particularity lies in the possibility of rotation of the panels along the longitudinal axis. The panels’ rotation allows varying shading degree in function of some parameters such as latitude and the different solar angles. In order to avoid any reflection losses due to imperfect inclination of the photovoltaic panels, 24 highly reflective aluminium mirrors were prepared with the objective of recovering the portion of solar radiation otherwise lost by reflection. For the study it was used the simulation software Autodesk® Ecotect® Analysis which allows to analyse the path of the shadows during the day and throughout the year for any latitude considered. For this study it was analyzed shading with the panels in a horizontal position. It was also analyzed the evolution of the percentage of shading simulating different latitudes. The results obtained show a great variation of the shading degree inside the structure during a single day and during the year. We can conclude that integrating this analysis with the energy balance it is possible to study the behaviour of photovoltaic greenhouses in order to integrate the energy production from renewable energy sources and agricultural production.

Over the last several years, solar energy technologies have been, or are in the process of being, deployed at unprecedented levels. A critical recent development, resulting from the massive scale of projects in progress or recently completed, is having the power sold directly to electric utilities. Such 'utility-scale' systems offer the opportunity to deploy solar technologies far faster than the traditional 'behind-the-meter' projects designed to offset retail load. Moreover, these systems have employed significant economies of scale during construction and operation, attracting financial capital, which in turn can reduce the delivered cost of power. This report is a summary of the current U.S. utility-scale solar state-of-the-market and development pipeline. Utility-scale solar energy systems are generally categorized as one of two basic designs: concentrating solar power (CSP) and photovoltaic (PV). CSP systems can be further delineated into four commercially available technologies: parabolic trough, central receiver (CR), parabolic dish, and linear Fresnel reflector. CSP systems can also be categorized as hybrid, which combine a solar-based system (generally parabolic trough, CR, or linear Fresnel) and a fossil fuel energy system to produce electric power or steam.

As the French government decided to reduce its financial support to photovoltaic energy, a first article identifies and comments the issues to be addressed to have a competitive French photovoltaic industry: to bet on second generation arrays (thin layer arrays), to have higher yearly objectives in terms of installed power (800 MW or 1 GW instead of 500 MW, in order to create a reference market), to redefine the financing and the electricity purchase scheme, to promote self consumption, to support exportation. The second article presents the first French photovoltaic test and certification centre, located near Chambery, where solar arrays are inspected and where their ageing is simulated through thermal fatigue and impact testing

A feasibility study has been carried out to assess the options to apply photovoltaic/thermal panels (PVT-panels) in collective solar thermal systems in urban areas in the Netherlands. The study was focused on the technical (architecture and installations) and the economical feasibility of collective PVT-systems in comparison with conventional solar thermal systems and combinations of photovoltaic (PV) panels and solar collectors. The results of the study also give insight into cost and the market for PVT-panels. Three case studies in which collective solar collector systems were applied are analyzed again by simulating the installation of a PVT-panels system and a separate solar thermal PV system [nl

Distributed solar photovoltaic (PV) markets are relatively non-transparent: PV price and product information is not readily available, searching for this information is costly (in terms of time and effort), and customers are mostly unfamiliar with the new technology. Quote aggregation, where third-party companies collect PV quotes on behalf of customers, may be one way to increase PV market transparency. In this paper, quote aggregation data are analyzed to study the value of transparency for distributed solar PV markets. The results suggest that easier access to more quotes results in lower prices. We find that installers tend to offer lower prices in more competitive market environments. We supplement the empirical analysis with key findings from interviews of residential PV installers.

With the introduction of a cost recovering energy feeding law, new possibilities open up for the building integration of photovoltaics and for the solar power generation at the ''Point of sale ''. Still, the appropriate Swiss market is marginal. Not all legal, technical and financial hurdles are removed. Here the photovoltaics with its building integration is in touch with an emotional factor of revaluation: An integration of photovoltaics adresses the building owner beyond their technical-economic value at a culturally abstract level - a wing of a butterfly oscillating in the sunlight also touches on a completely different level. Exactly the same the integration of photovoltaics makes the building to a unique piece of jewellery. In the pioneer phase of the photovoltaics market, architectonically successful integrations of photovoltaics succeeded in a break-through of the solar power generation. Photovoltaics at building coverings is more than a ''fashion '': it becomes a lever arm, with which the solarization of our society transports significant values. Apart from rational-technical considerations this effect has to be used to favour a broad application of photovoltaics with the building integration more purposefully.

Highlights: •A modular photovoltaic-thermochemical hybrid system prototype is proposed. •Net solar-electric efficiency up to 41% is achievable. •Stable solar power supply is achievable via convenient energy storage. •The modular design facilitates the scalability of the hybrid system. -- Abstract: A solar photovoltaic (PV) thermochemical hybrid system consisting of a point-focus Fresnel concentrator, a PV cell and a methanol thermochemical reactor is proposed. In particular, a reactor capable of operating under high solar concentration is designed, manufactured and tested. Studies on both kinetic and thermodynamic characteristics of the reactor and the system are performed. Analysis of numerical and experimental results shows that with cascaded solar energy utilization and synergy among different forms of energy, the hybrid system has the advantages of high net solar-electric efficiency (up to 41%), stable solar energy power supply, solar energy storage (via syngas) and flexibility in application scale. The hybrid system proposed in this work provides a potential solution to some key challenges of current solar energy utilization technologies.

Economic performance and policies for grid-connected residential solar photovoltaic systems in Brazil

International Nuclear Information System (INIS)

Mitscher, Martin; Rüther, Ricardo

2012-01-01

We analyze the economic competitiveness of grid-connected, distributed solar photovoltaic generation through small-scale rooftop installations in five Brazilian state-capitals. The locations represent a comprehensive set of the two essential parameters for the economic viability of PV—solar irradiation and local electricity tariffs. Levelized electricity costs (LEC) for PV generation and net present values (NPV) for a specific PV system are presented. The analysis comprises three different interest rate scenarios reflecting different conditions for capital acquisition to finance the generators; subsidized, mature market and country-specific risk-adjusted interest. In the NPV analysis, revenue flow is modeled by the sale of PV electricity at current residential tariffs assuming net metering. Using subsidized interest rates, the analysis shows that solar PV electricity is already competitive in Brazil, while in the country-specific risk-adjusted rate, the declining, but still high capital costs of PV make it economically unfeasible. At a mature market interest rate, PV competitiveness is largely dependent on the residential tariff. Economic competitiveness in this scenario is given for locations with high residential tariffs. We demonstrate the high potential of distributed generation with photovoltaic installations in Brazil, and show that under certain conditions, grid-connected PV can be economically competitive in a developing country. - Highlights: ► Debt financed grid-connected PV on Brazilian rooftops can be economically feasible since 2011. ► The cost of capital in Brazil is the decisive parameter in PV competitiveness with conventional generation sources. ► Low-cost, long-term financing is an essential requirement for PV to become an economically justifiable generation alternative. ► The Brazilian market holds huge potential for distributed, residential rooftop PV systems of small size.

To shed light on the movement of sustainable technologies from basic science to widespread use, this chapter describes key aspects of the quite different paths followed by two important examples—photovoltaics (a product) and passive-house buildings (a standard). Discussion of photovoltaics includes the experience curve concept, the increasing significance of balance-of-system costs, and the importance of market heterogeneity (niches and sub-national markets) to the long-term trajectory of major cost reductions. Discussion of passive-houses highlights the array of technical developments needed for present-day energy efficient houses, and the relevance of "stretch" standards to the development of a market for very high-performance houses.

Holdermann, Claudius; Kissel, Johannes; Beigel, Jürgen

2014-01-01

This paper examines the economic viability of small-scale, grid-connected photovoltaics in the Brazilian residential and commercial sectors after the introduction of the net metering regulation in April 2012. This study uses the discounted cash flow method to calculate the specific investment costs that are necessary for photovoltaic systems to be economically viable for each of the 63 distribution networks in Brazil. We compare these values to the system costs that are estimated in the comprehensive study on photovoltaics that was developed by the Brazilian Association of Electric and Electronic Industries (ABINEE). In our calculation, we utilize the current electricity tariffs, including fees and taxes, which we obtained through telephone interviews and publicly available information. We obtained a second important parameter by simulating PV-systems with the program PV ⁎ Sol at the distribution company headquarters' locations. In our base case scenario that reflects the current situation, in none of the distribution networks photovoltaics is economically viable in either the commercial or residential sectors. We improved the environment for grid-connected photovoltaics in our scenarios by assuming both lower PV-system costs and a lower discount rate to determine the effect on photovoltaics viability. - Highlights: • We calculate the economic viability of photovoltaics in the residential and commercial sectors in Brazil. • The PV ⁎ Sol simulations are carried out at the headquarter locations for the 63 distribution companies. • Currently in none of the distribution networks, photovoltaics is economically viable in either the commercial or residential sectors. • We analyze how the variation of the specific investment costs and of the discount rate affects the economic viability

2017-02-01

Full Text Available In this paper, an exergy analysis of building integrated semitransparent photovoltaic thermal (BiSPVT system has been carried out. In the proposed system, the room below building integrated semitransparent photovoltaic thermal system has been considered as an air-conditioned (constant room temperature. Energy balance equation for each components namely semitransparent photovoltaic roof, floor and room air have been given. Based on energy balance, an analytical expression for room air, solar cell and room floor temperatures have been derived along with solar cell electrical efficiency. Further by considering the day lighting parameters, an overall exergy of the proposed system has been derived for different number of air change between the room and ambient air. It has been observed that there is reduction in room air and solar cell temperatures with an increase of number of air changes. However, solar cell electrical efficiency increases with decrease in temperature of solar cell. Further, it is found that an electrical power and illumination inside the room are more dominating in comparison with thermal exergy. An increase of 1.15% in an overall exergy is observed for the number of air changes varies from 0 to 4. Experimental validation of theoretical model has also been carried out.

The aim of the paper is to present the influence of the solar radiation variation on the performances of a stand alone photovoltaic pumping system which consists of photovoltaic generator, dc-dc converter, dc-ac inverter, an immersed group motor-pump and a storage tank that serves a similar purpose to battery storage. Hence a theoretical analysis (modelling and control) of the system is needed. Attention has been paid to the command of the power converters using MPPT and variable V/f laws. The MPPT control allows the extraction of the maximal output power delivered by the PV generator. The inverter ensures the PWM control of the asynchronous motor and a sine wave form of output signals. From the obtained simulation results, we will show that the decrease of the solar radiation degrades performances (the global efficiency and the flow rate) of the PV pumping system. The analysis is validated by simulation and experimental results. (author)

A photovoltaic module includes colorized reflective photovoltaic cells that act as pixels. The colorized reflective photovoltaic cells are arranged so that reflections from the photovoltaic cells or pixels visually combine into an image on the photovoltaic module. The colorized photovoltaic cell or pixel is composed of a set of 100 to 256 base color sub-pixel reflective segments or sub-pixels. The color of each pixel is determined by the combination of base color sub-pixels forming the pixel. As a result, each pixel can have a wide variety of colors using a set of base colors, which are created, from sub-pixel reflective segments having standard film thicknesses.

As a market segment for solar photovoltaic (PV) adoption, new homes have a number of attractive attributes. Homebuyers can easily roll the cost of the PV system into their tax-deductible home mortgage and, with rebates and other financial incentives, potentially achieve an immediate net-positive cash flow from the investment. New homes are amenable to building-integrated photovoltaics (BIPV), which are less susceptible to aesthetic concerns than traditional, rack-mounted systems. The performance of PV systems can be optimized on new homes by taking roof orientation and shading into account when designing the home. Perhaps most importantly, subdivisions with PV systems installed on a large number of homes offer potential cost savings from volume purchases of modules and inverters and from scale economies in system design and installation. Finally, the ability of builders to install PV as a standard feature on multiple homes in new subdivisions offers an opportunity to circumvent the high transaction costs and information-related market barriers typically confronted when each individual homeowner must make a decision about installing PV. Builders may benefit in several ways from incorporating PV into new homes. Builders may gain greater market differentiation, enhanced media exposure, and less community or political opposition to development projects. Additionally, if homebuyers place a high value on PV, builders may be able to earn additional profits, just as they would on granite countertops or other high-value home features. Although the impact of PV on the original sale price of new homes has not yet been rigorously examined, some limited empirical evidence does suggest that PV and energy efficient features may have a positive effect on resale value. Along with its unique advantages, residential new construction also faces unique barriers to PV adoption. Most fundamentally, perhaps, is the general aversion to technology risk within the building industry

Photovoltaic power in France, a declining sector

Figures from 2011 show an exceptional year in terms of grid connection and a poor year for business because the moratory on photovoltaic power decided end 2010 gave its full effect. The grid connections realized in 2011 resulted from installations decided before the moratory. The situation shows some inconsistencies: the household sector was not concerned by the moratory and nevertheless the drop of sales was sharp and even if the purchase price of the photovoltaic electricity was reduced from 0.58 to 0.35 euro/kWh it stays high when compared to 0.18 euro/kWh in Germany or 0.20 euro/kWh in Italy. The depressed nature of the market seems to go on in 2012. (A.C.)

Spatial lifecycles of cleantech industries – The global development history of solar photovoltaics

International Nuclear Information System (INIS)

Binz, Christian; Tang, Tian; Huenteler, Joern

2017-01-01

New industries develop in increasingly globalized networks, whose dynamics are not well understood by academia and policy making. Solar photovoltaics (PV) are a case in point for an industry that experienced several shifts in its spatial organization over a short period of time. A lively debate has recently emerged on whether the spatial dynamics in new cleantech sectors are in line with existing industry lifecycle models or whether globalization created new lifecycle patterns that are not fully explained in the literature. This paper addresses this question based on an extensive analysis of quantitative data in the solar PV sector. Comprehensive global databases containing 86,000 patents as well as manufacturing and sales records are used to analyze geographic shifts in the PV sector’s innovation, manufacturing and market deployment activities between 1990 and 2012. The analysis reveals spatial lifecycle patterns with lower-than-expected first mover advantages in manufacturing and market activities and an earlier entry of firms from emerging economies in manufacturing and knowledge creation. We discuss implications of these findings for the competitive positions of companies in developed and emerging economies, derive new stylized hypotheses for industry lifecycle theories, and sketch policy approaches that are reflexive of global interdependencies in emerging cleantech industries. - Highlights: • The global spatial lifecycle of the solar photovoltaic (PV) industry is analyzed. • Our data partly contradicts existing industry lifecycle theories. • Latecomers in China started manufacturing and deployment earlier than expected. • Pioneers in the US and EU retained significant first-mover advantages in patenting. • Industry lifecycle theory needs updates in the production and market dimensions.

On the use of hourly pricing in techno-economic analyses for solar photovoltaic systems

Highlights: • The typical price year (TPY) method is described. • The impact of pricing simplification models on revenues and NPV are tested. • The TPY is shown to be a good long-term price curve for techno-economic studies. • A static mean annual price can replace hourly in the Swedish market with minimal error. - Abstract: The use of hourly prices in distributed photovoltaic (PV) techno-economic analysis is rare, but may become necessary as time-of-day retail pricing becomes more common. A methodology is presented for selecting an hourly price curve suitable for long-term analysis, called the typical price year (TPY), which is based on the methodology for TMY weather data. Using a techno-economic analysis with annual revenues and net present value as indicators, a TPY curve for the Swedish market is validated and then compared to 18 price simplification methods to determine the error introduced by the use of non-hourly prices. Results show that the TPY method produces a curve which accurately represents long term pricing trends, but using a static annual mean introduces minor revenue errors of 1.3%. This suggests the TPY may not be necessary in the Swedish market, but further analysis of the method is suggested for other markets

A process including forming a photovoltaic solar cell on a substrate, the photovoltaic solar cell comprising an anchor positioned between the photovoltaic solar cell and the substrate to suspend the photovoltaic solar cell from the substrate. A surface of the photovoltaic solar cell opposite the substrate is attached to a receiving substrate. The receiving substrate may be bonded to the photovoltaic solar cell using an adhesive force or a metal connecting member. The photovoltaic solar cell is then detached from the substrate by lifting the receiving substrate having the photovoltaic solar cell attached thereto and severing the anchor connecting the photovoltaic solar cell to the substrate. Depending upon the type of receiving substrate used, the photovoltaic solar cell may be removed from the receiving substrate or remain on the receiving substrate for use in the final product.

Italian programs and goals for developing a photovoltaic (PV) industry and market are outlined. It is suggested that only a few megawatts of PVs will be produced for domestic consumption in the next few years, while the largest market is for developing nations where costly diesel-fueled generators are used. The installation of PV systems in developing areas will permit testing and scaling up of production capacities from several MW to several hundred MW and then to GW annual production. Approximately 55,000,000 was devoted to government research in PV in 1982 and a PV research laboratory is being built near Naples.

Photovoltaic (PV) systems (cells and arrays) for spacecraft power have become an international market. This market demands accurate prediction of the solar array power output in space throughout the mission life of the spacecraft. Since the beginning of space flight, space-faring nations have independently developed methods to calibrate solar cells for power output in low Earth orbit (LEO). These methods rely on terrestrial, laboratory, or extraterrestrial light sources to simulate or approximate the air mass zero (AM0) solar intensity and spectrum.

Prospects for concentrating photovoltaic (CPV) power are growing as the market increasingly values high power conversion efficiency to leverage now-dominant balance of system and soft costs. This trend is particularly acute for rooftop photovoltaic power, where delivering the high efficiency of traditional CPV in the form factor of a standard rooftop photovoltaic panel could be transformative. Here, we demonstrate a fully automated planar microtracking CPV system 660× concentration ratio over a 140∘ full field of view. In outdoor testing over the course of two sunny days, the system operates automatically from sunrise to sunset, outperforming a 17%-efficient commercial silicon solar cell by generating >50% more energy per unit area per day in a direct head-to-head competition. These results support the technical feasibility of planar microtracking CPV to deliver a step change in the efficiency of rooftop solar panels at a commercially relevant concentration ratio.

The use of photovoltaic (PV) technology in countries that do not presently have high technology industrial capacity was investigated. The relative cost of integrating indigenous labor (and manufacturing where available) into the balance of the system industry of seven countries (Egypt, Haiti, the Ivory Coast, Kenya, Mexico, Nepal, and the Phillipines) was determined. The results were then generalized to other countries, at most levels of development. The results of the study imply several conclusions: (1) the cost of installing and maintaining comparable photovoltaic systems in developing countries is less than in the United States; (2) skills and some materials are available in the seven subject countries that may be applied to constructing and maintaining PV systems; (3) there is an interest in foreign countries in photovoltaics; and (4) conversations with foreign nationals suggest that photovoltaics must be introduced in foreign markets as an appropriate technology with high technology components rather than as a high technology system.

Analysis of Selected Photovoltaic Panels Operating Parameters as a Function of Partial Shading and Intensity of Reflected Radiation

Directory of Open Access Journals (Sweden)

2018-03-01

Full Text Available Due to expansion of utilisation of photovoltaics in ordinary households, the question arises how this phenomenon affects the electric power of photovoltaic modules. The article deals with the electric power analysis of photovoltaic modules as a function of two very important factors. The first examined factor was partial shading, and the second factor was the intensity of reflected radiation. In order to determine the dependence of module power on the aforementioned parameters, a measurement system under laboratory conditions has been prepared. For identification of the reflected radiation effect on the power of the photovoltaic module, a series of measurements was performed on 7 different surfaces with the same radiation source. It is evident from obtained experimental result that the ratio of reflected irradiation on the solar module power is 1.29%. By simulation of partial shading of photovoltaic module, the decrease of 86.15% in its output power was identified.

The paper presents the most representative - from the three-year measurement time period - characteristics of daily and monthly electricity production from a photovoltaic conversion using modules installed in a fixed and 2-axis tracking construction. Results are presented for selected summer, autumn, spring and winter days. Analyzed measuring stand is located on the roof of the Faculty of Electrical Engineering Poznan University of Technology building. The basic parameters of the statistical analysis like mean value, standard deviation, skewness, kurtosis, median, range, or coefficient of variation were used. It was found that the asymmetry factor can be useful in the analysis of the daily electricity production from a photovoltaic conversion. In order to determine the repeatability of monthly electricity production, occurring between the summer, and summer and winter months, a non-parametric Mann-Whitney U test was used as a statistical solution. In order to analyze the repeatability of daily peak hours, describing the largest value of the hourly electricity production, a non-parametric Kruskal-Wallis test was applied as an extension of the Mann-Whitney U test. Based on the analysis of the electric energy distribution from a prepared monitoring system it was found that traditional forecasting methods of the electricity production from a photovoltaic conversion, like multiple regression models, should not be the preferred methods of the analysis.

The efficiency of the photovoltaic reduces when the photovoltaic cell temperature increased due to solar irradiance. One solution is come up with the cooling system photovoltaic system. This combination is forming the photovoltaic-thermal (PV/T) system. Not only will it generate electricity also heat at the same time. The aim of this research is to focus on the modeling and simulation of photovoltaic (PV) and photovoltaic-thermal (PV/T) electrical performance by using single-diode equivalent circuit model. Both PV and PV/T models are developed in Matlab/Simulink. By providing the cooling system in PV/T, the efficiency of the system can be increased by decreasing the PV cell temperature. The maximum thermal, electrical and total efficiency values of PV/T in the present research are 35.18%, 15.56% and 50.74% at solar irradiance of 400 W/m2, mass flow rate of 0.05kgs-1 and inlet temperature of 25 °C respectively has been obtained. The photovoltaic-thermal shows that the higher efficiency performance compared to the photovoltaic system.

The photovoltaic sector in France Year 2009

Durand, Yvonnick; Jacquin, Philippe

2010-01-01

According to statistics drawn up in 2009 by the Syndicat des Energies Renouvelables (SER, France's professional association of bodies involved in renewable energies), 250 MW of generating capacity were added during the year. This brings France's total installed photovoltaic capacity up to 430 MW. France's photovoltaic market grew from the world's 12. largest in terms of market size to 7. The broad guidelines which followed on from the legislation that emerged from the 'Grenelle of the Environment' are influencing the ways in which the market is to grow over the next few years: largest by the end of 2009. This was due to growth that was sustained by high feed-in tariffs and a drop in the price of equipment. - a target of 1100 MW of photovoltaic installed capacity by 2012, reaching 5 400 MW by 2020; - confirmation that tariff incentives will remain in place until 2012 and creation of an additional tariff for photovoltaic installations in large-sized buildings, such as commercial premises and industrial warehouses. This tariff has been fixed at 0,45 EUR per kWh; however, adjustment measures were announced at the end of 2009 to reduce a speculative approach that could ultimately lead to an hardening of access conditions to the higher tariffs. - the issuing of an invitation to tender for the construction of a least one photovoltaic power plant per region in France by 2011, providing a total of 300 MW of power. 2009 was mainly marked by an increase in the number of medium- and high-power plants, together with the emergence of a number of new organizations in the photovoltaic sector. The market continues to be strongly influenced by the priorities given to the integration of photovoltaics into buildings. The effects of the incentive measures that have been in place since 2006 (feed-in tariffs and fiscal measures) are still being felt. They continue to stimulate investment - both from private individuals and manufacturing organizations. In

Photovoltaic and photoelectrochemical conversion of solar energy.

2007-04-15

The Sun provides approximately 100,000 terawatts to the Earth which is about 10000 times more than the present rate of the world's present energy consumption. Photovoltaic cells are being increasingly used to tap into this huge resource and will play a key role in future sustainable energy systems. So far, solid-state junction devices, usually made of silicon, crystalline or amorphous, and profiting from the experience and material availability resulting from the semiconductor industry, have dominated photovoltaic solar energy converters. These systems have by now attained a mature state serving a rapidly growing market, expected to rise to 300 GW by 2030. However, the cost of photovoltaic electricity production is still too high to be competitive with nuclear or fossil energy. Thin film photovoltaic cells made of CuInSe or CdTe are being increasingly employed along with amorphous silicon. The recently discovered cells based on mesoscopic inorganic or organic semiconductors commonly referred to as 'bulk' junctions due to their three-dimensional structure are very attractive alternatives which offer the prospect of very low cost fabrication. The prototype of this family of devices is the dye-sensitized solar cell (DSC), which accomplishes the optical absorption and the charge separation processes by the association of a sensitizer as light-absorbing material with a wide band gap semiconductor of mesoporous or nanocrystalline morphology. Research is booming also in the area of third generation photovoltaic cells where multi-junction devices and a recent breakthrough concerning multiple carrier generation in quantum dot absorbers offer promising perspectives.

2016-10-01

Many new photovoltaic (PV) applications, such as the concentrating PV (CPV) systems, are appearing on the market. The main characteristic of CPV systems is to concentrate sunlight on a receiver by means of optical devices and to decrease the solar cells area required. A low CPV (LCPV) system allows optimizing the PV effect with high increase of generated electric power as well as decrease of active surface area. In this paper, an economic analysis and a life cycle assessment (LCA) study of a particular LCPV scheme is presented and its environmental impacts are compared with those of a PV traditional system. The LCA study was performed with the software tool SimaPro 8.0.2, using the Econinvent 3.1 database. A functional unit of 1 kWh of electricity produced was chosen. Carbon Footprint, Ecological Footprint and ReCiPe 2008 were the methods used to assess the environmental impacts of the LCPV plant compared with a corresponding traditional system. All the methods demonstrated the environmental convenience of the LCPV system. The innovative system allowed saving 16.9% of CO2 equivalent in comparison with the traditional PV plant. The environmental impacts saving was 17% in terms of Ecological Footprint, and, finally, 15.8% with the ReCiPe method.

Podder, A; Kapner, M

1981-02-01

An evaluation of 11 types of secondary batteries for energy storage in photovoltaic electric power systems is given. The evaluation was based on six specific application scenarios which were selected to represent the diverse requirements of various photovoltaic systems. Electrical load characteristics and solar insulation data were first obtained for each application scenario. A computer-based simulation program, SOLSIM, was then developed to determine optimal sizes for battery, solar array, and power conditioning systems. Projected service lives and battery costs were used to estimate life-cycle costs for each candidate battery type. The evaluation considered battery life-cycle cost, safety and health effects associated with battery operation, and reliability/maintainability. The 11 battery types were: lead-acid, nickel-zinc, nickel-iron, nickel-hydrogen, lithium-iron sulfide, calcium-iron sulfide, sodium-sulfur, zinc-chlorine, zinc-bromine, Redox, and zinc-ferricyanide. The six application scenarios were: (1) a single-family house in Denver, Colorado (photovoltaic system connected to the utility line); (2) a remote village in equatorial Africa (stand-alone power system); (3) a dairy farm in Howard County, Maryland (onsite generator for backup power); (4) a 50,000 square foot office building in Washington, DC (onsite generator backup); (5) a community in central Arizona with a population of 10,000 (battery to be used for dedicated energy storage for a utility grid-connected photovoltaic power plant); and (6) a military field telephone office with a constant 300 W load (trailer-mounted auxiliary generator backup). Recommendations for a research and development program on battery energy storage for photovoltaic applications are given, and a discussion of electrical interfacing problems for utility line-connected photovoltaic power systems is included.

The largest part of the market for autonomous photovoltaic cells consists of public lighting systems. In the Netherlands are circa 400 solar light lampposts. Suppliers of lampposts believe that the potential of that market is much larger. However, sales figures show that the market has come to a halt. It is the opinion of the suppliers that some prejudices exist with respect to usage aspects (e.g., high cost for purchase and maintenance, low reliability of the systems and sensitive for hooliganism). The (non)-existence of those prejudices is subject of this study

Consumer loss in Czech photovoltaic power plants in 2010–2011

International Nuclear Information System (INIS)

Průša, Jan; Klimešova, Andrea; Janda, Karel

2013-01-01

This paper provides a financial survey of a small sample of Czech photovoltaic (PV) plants. To evaluate the extent of market losses, we calculate the shadow market price of solar electricity. From the profit and loss accounts of the PV plants and the shadow market price we estimate the total economic loss generated by PV electricity sector in the Czech Republic. The presented microeconomic approach has two main advantages: firstly, we work with real observed data, which offsets the drawback of a limited sample. Secondly, the profit accounting calculation enables sensitivity analysis with respect to key variables of the plants. We show that money invested in PV plants would generate an annual loss of 8%. Given the estimated solar assets of CZK 165.6 billion (EUR 6.6 billion) as of December 2011, this translates in at least CZK 12.6 billion lost in the Czech solar sector in 2012. About 43% of this loss is due to high technology costs and corresponds to pure dead weight loss, while the remaining 57% constitute the redistributive profit component of subsidies. Finally, we calculate that unless electricity prices increase or technology costs decrease approximately sevenfold, PV plants will remain loss making. - Highlights: • We calculate economic losses generated by Czech photovoltaic power plants. • Without subsidies estimated loss is CZK 12.6 billion in 2012 (8% of invested assets). • 43% is the dead weight loss due to high technology costs. • 57% is the profit redistributed out of subsidies as interest payments to banks. • Only a 7-fold change in parameters of the model would make PV plants profitable

The figures collected for the first semester of 2015 show that the 2014 growth of photovoltaic energy is keeping on. In june 2015 the cumulated installed power reached 6046 MWc. The next challenge is the implementation in january 2016 of a new financial support mechanism based on additional income instead of an EDF's obligation to purchase at fixed tariffs. The additional income is due to be paid with regular periodicity rather than as a whole at the beginning of the project. The amount of the additional income will be calculated as a difference between a maximum target price and the average market price of electricity. This new financial support mechanism shows that the photovoltaic sector is entering a maturity phase. (A.C.)

Bower, Ward

1999-01-01

The International Energy Agency (IEA) is an energy forum for 24 industrialized countries and was established in 1974 as an autonomous body within the Organization for Economic Cooperation and Development (OECD). The IEA Photovoltaic Power Systems (PVPS) program implementing agreement was signed in 1993, and renewed for another five years in 1998. Twenty-two countries are collaborating under the auspices of the IEA in the PVPS to address common technical and informational barriers that often limit the rate at which photovoltaic technologies advance into the markets. Task V of the IEA PVPS is entitled ''Grid Interconnection of Building-Integrated and Other Dispersed Photovoltaic Power Systems.'' The task sponsored a workshop in September 1997 on grid-interconnection of photovoltaic systems and is planning a second workshop to address impacts of more penetration of dispersed systems into the utility grid. This paper will summarize the accomplishments of Task V over the last five years and will detail the planned work for the next three years

Multiphysics modelling and experimental validation of high concentration photovoltaic modules

2017-01-01

Highlights: • A multiphysics modelling approach for concentrating photovoltaics was developed. • An experimental campaign was conducted to validate the models. • The experimental results were in good agreement with the models. • The multiphysics modelling allows the concentrator’s optimisation. - Abstract: High concentration photovoltaics, equipped with high efficiency multijunction solar cells, have great potential in achieving cost-effective and clean electricity generation at utility scale. Such systems are more complex compared to conventional photovoltaics because of the multiphysics effect that is present. Modelling the power output of such systems is therefore crucial for their further market penetration. Following this line, a multiphysics modelling procedure for high concentration photovoltaics is presented in this work. It combines an open source spectral model, a single diode electrical model and a three-dimensional finite element thermal model. In order to validate the models and the multiphysics modelling procedure against actual data, an outdoor experimental campaign was conducted in Albuquerque, New Mexico using a high concentration photovoltaic monomodule that is thoroughly described in terms of its geometry and materials. The experimental results were in good agreement (within 2.7%) with the predicted maximum power point. This multiphysics approach is relatively more complex when compared to empirical models, but besides the overall performance prediction it can also provide better understanding of the physics involved in the conversion of solar irradiance into electricity. It can therefore be used for the design and optimisation of high concentration photovoltaic modules.

The claim that the use of solar energy through photovoltaic (PV) panels is a clean energy source is based, in most cases, considering only the generation of electricity by the group after manufacture and installation. Without considering the process of manufacture, neither more nor less CO2 emissions are produced, and other degradation environment, which vary according to the country's energy matrix in which these activities develop. This article uses analysis tools to study the impacts of life cycle environment that have passed since the exploitation of mineral deposits used in the manufacture of major components for the manufacture of the panel. In this study adds to quantify the emissions of various gases, emitted in the manufacturing process of photovoltaic modules, expressed in equivalent tons of CO2, resulting from the process and depending on the country in which the panel is manufactured and the depreciation of environmental liabilities, to allow life determination (author)

Material flows and emissions in all the stages of production of zinc, copper, aluminum, cadmium, indium, germanium, gallium, selenium, tellurium, and molybdenum were investigated. These metals are used selectively in the manufacture of solar cells, and emission and energy factors in their production are used in the Life Cycle Analysis (LCA) of photovoltaics. Significant changes have occurred in the production and associated emissions for these metals over the last 10 years, which are not described in the LCA databases. Furthermore, emission and energy factors for several of the by-products of the base metal production were lacking. This report aims in updating the life-cycle inventories associated with the production of the base metals (Zn, Cu, Al, Mo) and in defining the emission and energy allocations for the minor metals (Cd, In, Ge, Se, Te and Ga) used in photovoltaics.

Hong, Sungjun; Chung, Yanghon; Woo, Chungwon

2015-01-01

South Korea, as the 9th largest energy consuming in 2013 and the 7th largest greenhouse gas emitting country in 2011, established ‘Low Carbon Green Growth’ as the national vision in 2008, and is announcing various active energy policies that are set to gain the attention of the world. In this paper, we estimated the decrease of photovoltaic power generation cost in Korea based on the learning curve theory. Photovoltaic energy is one of the leading renewable energy sources, and countries all over the world are currently expanding R and D, demonstration and deployment of photovoltaic technology. In order to estimate the learning rate of photovoltaic energy in Korea, both conventional 1FLC (one-factor learning curve), which considers only the cumulative power generation, and 2FLC, which also considers R and D investment were applied. The 1FLC analysis showed that the cost of power generation decreased by 3.1% as the cumulative power generation doubled. The 2FCL analysis presented that the cost decreases by 2.33% every time the cumulative photovoltaic power generation is doubled and by 5.13% every time R and D investment is doubled. Moreover, the effect of R and D investment on photovoltaic technology took after around 3 years, and the depreciation rate of R and D investment was around 20%. - Highlights: • We analyze the learning effects of photovoltaic energy technology in Korea. • In order to calculate the learning rate, we use 1FLC (one-factor learning curve) and 2FLC methods, respectively. • 1FLC method considers only the cumulative power generation. • 2FLC method considers both cumulative power generation and knowledge stock. • We analyze a variety of scenarios by time lag and depreciation rate of R and D investment

Three essays on regulated markets. Renewable energies, hospital competition and health insurance

Unfried, Matthias

2012-11-15

This doctoral thesis presents an analysis of regulated markets especially focusing on the behavior of the actors, the effects of regulatory interventions on market outcome, and the necessity of the regulation itself. With respect to the particular characteristics, three different markets are analyzed: the German market for photovoltaic capacity, the German hospital sector, and the market for health insurance with respect to outpatient care. Chapter two provides an analysis of the German system of feed-in tariffs for photovoltaic power with respect to effectiveness and efficiency. To ensure a certain volume of investment in photovoltaic capacity investors receive fixed feed-in tariffs for 20 years for each unit of energy they feed into the grid. This remuneration is reduced according to a certain cut-off scheme for devices which will be installed in the future. In the past view years, an enormous volume of photovoltaic devices has been installed, especially in the weeks before the cut-offs. To analyze the efficiency and the effectiveness of the German feed-in tariff system, first, the determinants of such investment are analyzed by estimating an Error Correction model. The results of the estimation are used to simulate alternative mechanisms of adjusting the feed-in tariffs and compare them to the current regime in terms of target achievement and social costs. One of the key results is that the current system causes early investments, but does not induce over-investment. Moreover, it is shown that a system of continuously adjusted feed-in tariffs could be more appropriate than the current regime and that the adjustment should be related to the investment costs. In chapter three, the German hospital market which is characterized by regulated treatment fees and several different ownership types is analyzed. This part of the thesis tries to answer the question how the existence of non-profit hospitals influences market outcome and welfare compared to a market where

This article gives an overview of the marketing options available to operators of photovoltaic and wind power plants today. These include in particular the marketing channels specified in the newly incorporated Part 3a of the 2012 Renewable Energy Law (EEG), the use of the market premium and the green electricity privilege. Under certain conditions there is also some scope today for developing marketing models outside the purview of the EEG. Within this category the article takes a look at the options of self-supply and direct supply. In this context it also describes and assesses the market integration model that was newly introduced to the EEG in August 2012 through what has come to be known as the PV Amendment.

Economic Analysis of Photovoltaics versus Traditional Energy Sources: Where are We Now and Where Might We Be in the Near Future? (Presentation)

A precipitous drop in the price of the crystalline silicon solar photovoltaic (PV) modules typically employed for residential applications has recently been observed: The typical sales price for modules was around $4/WP DC in 2008 but could easily approach $1.50/W WP DC by the end of this year. As module price declines continue, and as gains are also realized in balance-of-system costs, the economics of PV systems for power generation become increasingly competitive. In this presentation, we will examine whether solar will reach grid parity in the United States if monocrystalline silicon modules achieve an optimistic-case scenario in efficiency and cost. The analysis suggests that PV systems are already economically viable in select markets, but further cost reductions and efficiency improvements above and beyond the monocrystalline optimistic-case scenarios are necessary in order to be competitive against incumbent electricity production in most markets across the United States. In this presentation we also provide an initial overview of cost considerations for electric vehicle charging with PV.

As consequence of Europe's climate and energy agenda, the European Union will generate some 50 percent of its electricity from renewables by 2030. By 2050, the EU's power system will have to be completely carbon-free. Solar photovoltaics and wind power - driven by significant cost reductions - will almost certainly contribute the biggest share of the zero-carbon technologies. Given the specific characteristics of wind power and photovoltaics (intermittent generation, high capital costs, very low variable costs), they will fundamentally change both market operations and the market design framework. Decarbonisation rests on continuous investments in these technologies. Usually it is expected that the energy market will deliver these investments, in combination with the emissions trading system. But is this view, based on simple textbook economics, enough to enable the required investments under real world conditions? In this paper, we argue that this rather theoretical view to power market design is not the way forward. Instead, a more pragmatic approach is needed, that takes into account the complex practical, political, and economic challenges of the transition towards a carbon-free power system. Thus, we propose to think of the future European market design as a Power Market Pentagon.

2016-01-01

As it seems there is a market for small size solar kits (or 'pico-photovoltaic' devices) in Sub-Saharan Africa (between 2012 and 2014, the number of people having a better access to energy thanks to these devices increased from 4 millions to 35 millions), this paper aims at assessing the economic viability of these devices, at seeing how to give access to these products for rural and disadvantaged populations. It highlights innovations implemented by actors of this sector in terms of business models, technologies, distribution channels, or partnerships. Thus, the authors propose an overview of the situation of solar energy in Africa, outline that pico photovoltaic could help to overcome a poor electrification. They discuss the specificities of these devices and present some examples of solar lamps. They analyse the economic, medical, environmental, and educative impacts of these devices as well as their impact on well-being and safety. They briefly indicate the main actors of off-grid solar energy and micro-grid solar energy. They discuss the issue of financing, that of distribution, credit possibilities (pay-as-you-go, micro-credit), and finally propose an overview of the African market, with notably the example of solar pico-lamps

Measuring market performance in restructured electricity markets: An empirical analysis of the PJM energy market

Science.gov (United States)

Tucker, Russell Jay

2002-09-01

Today the electric industry in the U.S. is transitioning to competitive markets for wholesale electricity. Independent system operators (ISOs) now manage broad regional markets for electrical energy in several areas of the U.S. A recent rulemaking by the Federal Energy Regulatory Commission (FERC) encourages the development of regional transmission organizations (RTOs) and restructured competitive wholesale electricity markets nationwide. To date, the transition to competitive wholesale markets has not been easy. The increased reliance on market forces coupled with unusually high electricity demand for some periods have created conditions amenable to market power abuse in many regions throughout the U.S. In the summer of 1999, hot and humid summer conditions in Pennsylvania, New Jersey, Maryland, Delaware, and the District of Columbia pushed peak demand in the PJM Interconnection to record levels. These demand conditions coincided with the introduction of market-based pricing in the wholesale electricity market. Prices for electricity increased on average by 55 percent, and reached the $1,000/MWh range. This study examines the extent to which generator market power raised prices above competitive levels in the PJM Interconnection during the summer of 1999. It simulates hourly market-clearing prices assuming competitive market behavior and compares these prices with observed market prices in computing price markups over the April 1-August 31, 1999 period. The results of the simulation analysis are supported with an examination of actual generator bid data of incumbent generators. Price markups averaged 14.7 percent above expected marginal cost over the 5-month period for all non-transmission-constrained hours. The evidence presented suggests that the June and July monthly markups were strongly influenced by generator market power as price inelastic peak demand approached the electricity generation capacity constraint of the market. While this analysis of the

Global PV Market Development

The dawn of 2009 saw several events which caused major turbulence in the global photovoltaic industry. In 2008 the Spanish PV market grew beyond all expectations and even outranked Germany as the world's number one market. However, the promotion scheme was modified and a market cap was introduced in 2009, cutting back the maximum capacity to be installed to about the level of 2007. In addition, the industry is facing an oversupply of PV modules and a harsh recession which is significantly affecting the traditionally strong PV markets. International photovoltaic companies are challenged by a changing market situation: all of a sudden, competition has increased significantly, pushing the customer to the fore. As a result, a consolidation process is expected within the PV industry worldwide. However, the story is not all negative. In the U.S., the election of Barack Obama may be seen as the starting signal for a massive expansion in PV, likely to bring the country to first place globally within the next five years. Furthermore, different markets and market segments are being opened up - especially in Europe - thanks to the gradual arrival of generation parity and new PV support mechanisms. EuPD Research has observed and studied international PV markets since its foundation. The information included in the presentation is based on a wide range of quantitative and qualitative studies that EuPD Research has conducted in the key markets since 2002. Florian Schmidt, EuPD Research's Head of Product Management, will give an overview of the global PV market and how it is developing in this crucial year 2009. Aspects such as technology development, production capacities and the demand side will be included, with a special emphasis on the European PV markets. So far Chinese PV companies have often benefited from the booming PV markets in Europe, above all Germany and Spain. Due to the lack of domestic market, the Chinese industry strongly depends on the export and is

Analysis on PV system sales price and subsidy through buy-back which make photovoltaics cost-competitive by 2030 in Japan

International Nuclear Information System (INIS)

Endo, E.; Ichinohe, M.

2004-01-01

The purpose of this paper is to analyze PV system sales price and subsidy through buy-back which make photovoltaics cost-competitive against other energy technologies and make the target for PV capacity achievable by 2030 in Japan under expected carbon tax. For the analysis energy system of Japan is modeled by using MARKAL. According to the results of analysis, under 6000 JPY/t-C carbon tax, photovoltaics needs subsidy for a while even if we taking both fuel savings and Green Credit into account. For attaining the national target for PV capacity in 2010, photovoltaics needs more expensive buy-back than that in present, but after 2010 necessary buy-back decreases gradually. If 120 JPY/W PV system sales price is attained by 2030, photovoltaics becomes cost-competitive without any supports. Subsidy through buy-back becomes almost need not in 2030, if we can reduce it less than 170 JPY/W. The total subsidy meets peak in 2025. It is much more than ongoing subsidy to capital cost of PV systems, but annual revenue of the assumed carbon tax can afford enough the annual total subsidy. This means if photovoltaics can attain the PV system sales price, we should support it for a while by spending carbon tax revenue effectively and efficiently. (authors)

Recent research shows significant differences in the levelised photovoltaics (PV) electricity cost calculations. The present paper points out that no unique or absolute cost figure can be justified, the correct solution is to use a range of cost figures that is determined in a dynamic power portfolio interaction within the financial scheme, support mechanism and industry cost reduction. The paper draws attention to the increasing role of financial investors in the PV segment of the renewable energy market and the importance they attribute to the risks of all options in the power generation portfolio. Based on these trends, a former version of a financing model is adapted to project the energy mix changes in the EU electricity market due to investors behaviour with different risk tolerance/aversion. The dynamic process of translating these risks into the return expectation in the financial appraisal and investment decision making is also introduced. By doing so, the paper sets up a potential electricity market trend with the associated risk perception and classification. The necessary risk mitigation tasks for all stakeholders in the PV market are summarised which aims to avoid the burden of excessive risk premiums in this market segment. (author)

Electricity production from small solar photovoltaic systems in Spain obtains a premium pnce of 0,36 ε/kWh over the electricity market price or a fix price of 0,40 ε/kWh. The development of these small systems in Spain clearly demonstrates that the established prime is not sufficient in the majority of locations. On the other hand, the prime revision set up by the RD 2818/98, considering the profitability of the renewable installations, demand a regional analysis of small PV systems profitability necessary in Spain. The accomplished results permit to conclude that the amount of the current prime is by itself insufficient to make profitable the small grid-connected PV systems in anywhere of the national geography. To guarantee the profitability of these systems it should be necessary to place the fix price at around 0,93 ε/kWh. However, if the duplication of the current price obtained by these installations was considered, this could ensure the profitability of these small systems in at least the 77% of the land.

Full Text Available The photovoltaic facility agriculture is developing rapidly in recent years, but there are many problems brought out, even in some important demonstration projects, due to the lack of standards. In order to solve some of these problems, we set up a photovoltaic facilities agricultural system in Guilinyang University City, Haikou, China and make an in-depth study on the photovoltaic facility agricultural system and its related problems. In this paper we disclose some of the experimental results. We plant corianders under two kinds of solar cell panels and general double glass assembly already sold on the market. Experiments showed that the square format cell panels are much better than row type, and the next one is general double glass assembly sold on the market, the last is the case without any shelter. 30 days after planting, the height of coriander plants are 50mm, 30mm, 23mm and 20mm correspondingly. The two typical solar cell panels have gaps between cells, and can save much more energy and improve power generation efficiency, we arrange the panels at optimum tilted angle, and design the system as open structure to save more energy. The photovoltaic facilities agricultural system we set up in Guilinyang University City can achieve much high solar energy efficiency than others and has broad application prospects.

Tour, Arnaud de la; Glachant, Matthieu; Meniere, Yann

2011-01-01

China is the largest solar photovoltaic cell producer in the world, with more than one third of worldwide production in 2008, exporting more than 95 percent of what it produces. The purpose of this paper is to understand the drivers of this success and its limits, with a particular emphasis on the role of technology transfers and innovation. Our analysis combines a review of international patent data at a detailed technology level with field interviews of ten Chinese PV companies. We show that Chinese producers have acquired the technologies and skills necessary to produce PV products through two main channels: the purchasing of manufacturing equipment in a competitive international market and the recruitment of skilled executives from the Chinese diaspora who built pioneer PV firms. The success of these firms in their market is, however, not reflected in their performance in terms of innovation. Rather, patent data highlight a policy-driven effort to catch up in critical technological areas. - Research Highlights: →China has become the world leader in the production of PV cells and modules, but remains far behind industrialized countries in the more upstream segments of the photovoltaic industry. →International technology transfers from industrialized countries to China have taken place through two main channels: the competitive market of manufacturing equipments, and labour mobility. →Fierce competition between equipment manufacturers and public availability of core technology have prevented intellectual property rights from hindering technology transfers towards China. →As compared with their foreign competitors, Chinese firms file many patents, but of low technical and commercial value. →Chinese firms' innovation is focused on process rather than on products.

The most important assets of photovoltaic energy for sustainable development are its simplicity (no need for complicated thermodynamical cycles) and the universal availability of the sun which explains its great popularity. The main restraint to its full development is the high cost of the technologies used. The silicon technology is the historical technology, it has high conversion rates but is expensive because of high fabrication costs. This technology represents 80% of the market. On the other hand the thin film technology with CdTe, CIS or CIGS is promising in terms of costs but requires research works to increase its conversion rate. Japan and Germany are the leader countries in terms of photovoltaic for research, industrial fabrication or state support, they are followed by Spain, Usa, and China. (A.C.)

Highlights: • Performance analysis of 3.2 kW_P CdTe PV system has been carried out. • Performance ratio and thermodynamic efficiencies have been determined. • Electrical parameters have been assessed at alternative reporting conditions. • Exergy analysis of the system has been carried out. • Degradation rate of the system has been calculated to be 0.18%/year. - Abstract: The solar photovoltaic (PV) technology market has increased rapidly with the continuously increasing electricity demand and climate concerns. With the increased PV installed capacity, the performance analysis of these systems has become critically important in order to ensure its reliable operation for a long lifetime, monetary payback and to identify the scope of improvement. The well-established conventional energetic performance analysis techniques are quantitative approaches based on energy conservation while the exergetic performance analysis is the qualitative method which is based on second law of thermodynamics. In this paper, an approach for energetic and exergetic performance analysis has been developed so as to determine the long term performance of PV systems in real operating conditions. A methodology has been proposed for utilizing the long term time series outdoor data in order to assess the performance of PV system statistically and to determine the system degradation rate. The degradation rate of 3.2 kW_P CdTe PV system is found to be 0.18% per year after 23 months of operation in composite climate which is lower than the reported degradation rate of earlier CdTe technology. The average performance ratio (PR), energetic and exergetic efficiency of the system is found to be 0.89%, 9.84% and 10.62% respectively. The average exergetic efficiency is found to be increased by 12% by utilizing the recoverable thermal exergy loss in photovoltaic-thermal system. The instantaneous PR of 93.5% of the per minute data is found to be in the range of 0.84–0.95. Additionally, the

Here, we discuss the local photovoltaic characteristics of a structured bulk heterojunction, organic photovoltaic devices fabricated with a liquid carbazole, and a fullerene derivative based on analysis by scanning kelvin probe force microscopy (KPFM). Periodic photopolymerization induced by an interference pattern from two laser beams formed surface relief gratings (SRG) in the structured films. The surface potential distribution in the SRGs indicates the formation of donor and acceptor spatial distribution. Under illumination, the surface potential reversibly changed because of the generation of fullerene anions and hole transport from the films to substrates, which indicates that we successfully imaged the local photovoltaic characteristics of the structured photovoltaic devices. Using atomic force microscopy, we confirmed the formation of the SRG because of the material migration to the photopolymerized region of the films, which was induced by light exposure through photomasks. The structuring technique allows for the direct fabrication and the control of donor and acceptor spatial distribution in organic photonic and electronic devices with minimized material consumption. This in situ KPFM technique is indispensable to the fabrication of nanoscale electron donor and electron acceptor spatial distribution in the devices.

Solar energy is the most promising and powerful energy source among renewable energies. Photovoltaic electricity is obtained by direct transformation of the sunlight into electricity by means of photovoltaic cells. The objective of this work is to develop photovoltaic cells with back inter-digitated contacts.

The distribution of the photovoltaic systems is faced with technological and economic problems, and the businesses and corporations feel burdened by the photovoltaic system's dubious economic value and high construction costs. Thus, not too many enterprises or private citizens have been participating in the business of installing photovoltaic systems. Moreover, because of lack of skills in integrating engineering and architectural design, they are experiencing difficulties even in using the technologies that have already been developed and available for application. To provide the basic information and specific data required for making the guidelines for developing photovoltaic technologies, this paper evaluates the system types, the actual state of operation, and performance of the two photovoltaic systems that are installed in Kiemyung University's Osan Building and Dongho Elementary School in Daegu Metropolitan City

Energy analysis of solar photovoltaic module production in India

Prakash, R.; Bansal, N.K.

1995-01-01

The objective of this article is to evaluate the energy consumption in solar photovoltaic (SPV) module production in India and examine its implications for large-scale introduction of SPV plants in the country. Data on energy used in SPV production were collected from existing manufacturing facilities in the country. The energy payback period turns out to be approximately 4 years. This is comparable to energy payback periods of similar modules produced internationally. However, if an ambitious program of introducing SPV power production is undertaken to contribute substantially to the power scenario in the country, an annual growth rate beyond 21% will render the program an energy sink rather than an energy source, as borne out by dynamic energy analysis. Policy implications are also discussed in light of this analysis

Performance Analysis of Photovoltaic Water Heating System

Directory of Open Access Journals (Sweden)

Tomas Matuska

2017-01-01

Full Text Available Performance of solar photovoltaic water heating systems with direct coupling of PV array to DC resistive heating elements has been studied and compared with solar photothermal systems. An analysis of optimum fixed load resistance for different climate conditions has been performed for simple PV heating systems. The optimum value of the fixed load resistance depends on the climate, especially on annual solar irradiation level. Use of maximum power point tracking compared to fixed optimized load resistance increases the annual yield by 20 to 35%. While total annual efficiency of the PV water heating systems in Europe ranges from 10% for PV systems without MPP tracking up to 15% for system with advanced MPP trackers, the efficiency of solar photothermal system for identical hot water load and climate conditions is more than 3 times higher.

Interface chemistry can control the performance and operational lifetime of solar cells, especially thin-film, polycrystalline devices. The composition and elemental integrity of device surfaces, internal junctions, layer and defect interfces can be related to and dominate the electroptical characteristics of the materials/ devices. This paper examines the compositional properties of external and internal surfaces in polycrystaline solar cells, utilizing high-resolution, complementary surface analysis techniques. The electronic properties of these same regions are evaluated using microelectrical characterization methods. Cell performance, in turn, is explained in terms of these relation-ships. Specifically, two solar cell types are used as examples: (1) the polycrystalline Si homojunction and (2) the (Cd Zn)S/CuInSe 2 heterojunction. Throughout these investigations of photovoltaic devices, the limitations and strengths of the surface and electrical microanalyses techniques are emphasized and discussed. (Author) [pt

Heidenreich, M.

2002-01-01

Photovoltaics is the sector of the future in this millennium. The process of human urbanization has led to a high demand for electricity; at the same time high-density urban settlement offers an enormous surface area that could be used for photovoltaic equipment. Such surfaces include rooftops, building facades, parking lots for automobiles, train stations and solar soundproofing walls. According to conservative estimates, Austria has sufficient surface area for a peak solar output of 4,000 MW. This would be sufficient to supply some 1.6 million households with electricity from unlimited solar energy. However, a tremendous marketing effort will be required in order to achieve generation on such a scale. (author)

New Best-Practices Guide for Photovoltaic System Operations and Maintenance

2017-05-24

Fact sheet summarizing technical report TP-7A40-67553. As solar photovoltaic (PV) systems have continued their transition from niche applications into large, mature markets in the United States, their potential as financial investments has risen accordingly. Mainstream investors, however, need to feel confident about the risk and return of solar photovoltaic (PV) systems before committing funds. A major influence on risk and return for PV is operations and maintenance (O&M) - but O&M practices and costs vary widely across the United States, making these variables difficult for investors to predict. To address this barrier to continued PV investment, the PV O&M Working Group has developed a new best-practices guide for PV O&M.

Hybrid photovoltaic-diesel-battery systems for remote energy supply

Photovoltaic solar generators combined with diesel engines and battery energy storage are powering isolated mountain lodges, information centres in nature parks, isolated farms or dwellings all over Europe. A total of 300000 buildings in Europe are estimated to be not connected to the public grid. This represents a major market potential for photovoltaics, as often photovoltaic power generation is less expensive than a connection to the electric utility. The Fraunhofer Institute for Solar Energy Systems ISE has planned, realized and monitored about 30 hybrid remote energy supply systems with PV generators typically around 5 kW for loads typically around 20 kWh per day. More than one hundred years of operational experience accumulated so far, are a sound foundation on which to draw an interim balance over problems solved and technical questions still under development. Room for further technical development is seen in the domain of system reliability and the reduction of operating costs as well as in the optimization of the utilisation of the electric energy produced by the PV generator.

This paper forecasts the photovoltaic (PV) market growth for the 1990s. Ten years of PV history are reviewed and used to establish market trends in terms of average selling price (ASP) and kilowatts shipped by market segment. The market is segmented into indoor consumer, stand-alone, and grid-connected applications. Indoor consumer presently represents a saturated market and is fairly predictable. The stand-alone market (i.e. not connected to the utility grid) is fairly stable and predictable. The utility PV market however is highly dependent on a number of market factors such as the cost of conventional energy the cost of PV systems utility acceptance of PV and regulatory controls. Government and institutional regulations, environmental issues, and OPEC and Middle East politics will have the greatest impact on the cost of conventional fuels. Private and federal investment in PV technology development could have a significant impact on the cost of PV systems. Forecasts are provided through the year 2000 for indoor consumer stand-alone and utility markets

Full Text Available This paper presents the design analysis of a photovoltaic (PV system to power the CAD/CAM Laboratory at the Department of Mechanical Engineering, University of Port Harcourt. Life cycle cost and break-even point analyses are also carried out to assess the economic viability of the system. The unit cost of electricity for the designed PV system is high compared to the current unit cost of the municipally supplied electricity, but will be competitive with lowering cost of PV system components and favourable government policies on renewable energy. The approach and data provided are useful for designing solar systems in the area. The automated MS Excel spreadsheet developed could be used for the design and economic analyses of PV system in any other geographical region once the input data are sorted. Since about 90% of businesses in Nigeria currently own diesel generators, it is expected that future work should be devoted to the optimum combination of PV-Battery-Diesel system in electricity generation for optimum economic benefits to the country.

The effects of the German renewable energy sources Act (EEG) on market, technical and industrial development

International Nuclear Information System (INIS)

Stryi-Hipp, G.

2004-01-01

Since 1999, the German photovoltaic market has been growing rapidly. In 2003, more than 130 MWp PV systems were installed in Germany; in 2004, more than 200 MWp are expected to be installed additionally. The main reason for this impressive market success has been the market stimulation policy of the German government. In January 1999, the 100.000 Roofs Programme for photovoltaic systems had started, offering interest-reduced loans for PV systems. In April 2000, it was backed by the Renewable Energy Sources Act (EEG), which considerably increased the feed-in tariff to 99 Pfennig (0.51 euros) per kWh. Since then, the PV market has boomed. In 2003, the 100,000 Roofs Programme (HTRP) ended successfully, after loans for more than 300 MWp PV systems had been granted. In order to fill the gap created by the termination of the programme, the government decided to increase the feed-in tariff provided by the EEG. Since January 2004, grid-connected PV systems on roofs and facades receive a tariff between 0,540 euros and 0,624 euros per kWh over 20 years. This improvement of the EEG further increased the interest in photovoltaics. The growth rate of the photovoltaic market, exceeding 50% in 2004, has led to the demand being higher than the available supply of PV systems. (author)

An Economic Analysis of Residential Photovoltaic Systems with and without Energy Storage

Science.gov (United States)

Kizito, Rodney

Residential photovoltaic (PV) systems serve as a source of electricity generation that is separate from the traditional utilities. Investor investment into residential PV systems provides several financial benefits such as federal tax credit incentives for installation, net metering credit from excess generated electricity added back to the grid, and savings in price per kilowatt-hour (kWh) from the PV system generation versus the increasing conventional utility price per kWh. As much benefit as stand-alone PV systems present, the incorporation of energy storage yields even greater benefits. Energy storage (ES) is capable of storing unused PV provided energy from daytime periods of high solar supply but low consumption. This allows the investor to use the stored energy when the cost of conventional utility power is high, while also allowing for excess stored energy to be sold back to the grid. This paper aims to investigate the overall returns for investor's investing in solely PV and ES-based PV systems by using a return of investment (ROI) economic analysis. The analysis is carried out over three scenarios: (1) residence without a PV system or ES, (2) residence with just a PV system, and (3) residence with both a PV system and ES. Due to the variation in solar exposure across the regions of the United States, this paper performs an analysis for eight of the top solar market states separately, accounting for the specific solar generation capabilities of each state. A Microsoft Excel tool is provided for computation of the ROI in scenario 2 and 3. A benefit-cost ration (BCR) is used to depict the annual economic performance of the PV system (scenario 2) and PV + ES system (scenario 3). The tool allows the user to adjust the variables and parameters to satisfy the users' specific investment situation.

Performance of photovoltaic (PV) module is greatly dependent on the solar irradiance, operating temperature, and shading. Solar irradiance can have a significant impact on power output of PV module and energy yield. In this paper, a maximum PV power which can be obtain in Ramadi city (100km west of Baghdad) is practically analyzed. The analysis is based on real irradiance values obtained as the first time by using Soly2 sun tracker device. Proper and adequate information on solar radiation and its components at a given location is very essential in the design of solar energy systems. The solar irradiance data in Ramadi city were analyzed based on the first three months of 2013. The solar irradiance data are measured on earth's surface in the campus area of Anbar University. Actual average data readings were taken from the data logger of sun tracker system, which sets to save the average readings for each two minutes and based on reading in each one second. The data are analyzed from January to the end of March-2013. Maximum daily readings and monthly average readings of solar irradiance have been analyzed to optimize the output of photovoltaic solar modules. The results show that the system sizing of PV can be reduced by 12.5% if a tracking system is used instead of fixed orientation of PV modules.

Carbon auctions, energy markets and market power: An experimental analysis

International Nuclear Information System (INIS)

Dormady, Noah C.

This paper provides an experimental analysis of a simultaneous energy-emissions market under conditions of market power. The experimental design employs real-world institutional features; including stochastic demand, permit banking, inter-temporal (multi-round) dynamics, a tightening cap, and resale. The results suggest that dominant firms can utilize energy-emissions market linkages to simultaneously inflate the price of energy and suppress the price of emissions allowances. Whereas under prior market designs, regulators were concerned with dominant firms exercising their market power over the emissions market to exclude rivals and manipulate the permit market by hoarding permits; the results of this paper suggest that this strategy is less profitable to dominant firms in contemporary auction-based markets than strategic capacity withholding in the energy market and associated demand reduction in the emissions market. - Highlights: • Laboratory simulation of joint energy-emissions market. • Evaluates market power under collusion and real-world institutional features. • Dominant firms can exercise market power to inflate energy prices. • Dominant firms can exercise market power to suppress emissions prices. • Supply withholding is an implicit demand reduction in the emissions market

Graphical abstract: - Highlights: • Initial growth mode of co-evaporated films was observed. • Balanced crystal growth leads to improvement of photovoltaic performance. • Crystal growth of fullerene during co-evaporation process was restricted. • The power conversion efficiency of 3% was obtained without electron blocking layer. - Abstract: Bulk heterojunction structures composed of electron donor and acceptor molecules for application in high-performance organic photovoltaics studied. To fabricate these structures, the co-evaporation method in vacuum is commonly applied; however, the details of the crystal growth process during co-evaporation have not yet been established. Here, we focused on structural analysis of blend films composed of phthalocyanine and fullerene based on initial growth stage. Similar crystal growth behavior to that typically observed in single-component molecules is obtained for the films. These results suggest that the competitive crystal growth between donors and acceptors occurs during co-evaporation process. The balance of thin film growth among donor and acceptor molecules can be related to improved photovoltaic performance. The homogeneous blend structure leads to improvement of the power conversion efficiency from 1.2% to 3.0%.

Evolution of consumer information preferences with market maturity in solar PV adoption

Science.gov (United States)

Cale Reeves, D.; Rai, Varun; Margolis, Robert

2017-07-01

Residential adoption of solar photovoltaics (PV) is spreading rapidly, supported by policy initiatives at the federal, state, and local levels. Potential adopters navigate increasingly complex decision-making landscapes in their path to adoption. Much is known about the individual-level drivers of solar PV diffusion that steer adopters through this process, but relatively little is known about the evolution of these drivers as solar PV markets mature. By understanding the evolution of emerging solar PV markets over time, stakeholders in the diffusion of solar PV can increase policy effectiveness and reduce costs. This analysis uses survey data to compare two adjacent markets across a range of relevant characteristics, then models changes in the importance of local vs cosmopolitan information sources by combining theory relating market maturity to adopter behavior with event-history techniques. In younger markets, earlier, innovative adoptions that are tied to a preference for cosmopolitan information sources are more prevalent than expected, suggesting a frustrated demand for solar PV that segues into adoptions fueled by local information preferences contemporary with similar adoptions in older markets. The analysis concludes with policy recommendations to leverage changing consumer information preferences as markets mature.

In this work we present an economic assessment photovoltaic systems using single axis and dual axis solar trackers. The analysis was carried out for the city of Sao Paulo and the results show that in comparison with fixed installations, the single axis system and the dual axis system produce respectively 19.6% and 24.7% more power. The power output of the dual axis system is 4.3% greater than the power output of the single axis system. Considering an annual discount rate of 12% and the equipment cost, the cost of the surplus energy due to the use of the single axis and the dual axis trackers was R$0.25/kWh and R$0.18/kWh. Because the average cost of electricity produced by photovoltaic modules is R$3/kWh, we recommend the installation of solar trackers. (author)

Highlights: • Application of RCM, based on FMEA, to photovoltaic systems. • MBS and FMEA determine RPN. • New maintenance plan aimed to reduce fixed RPN of criticalities. • Lower values of RPN by FMEA and major reliability of system obtained. - Abstract: There have been many scientific advances in the improvement of renewable energy systems. Recently, considerable interest has been given to their optimized management during their service life due to a large increase in the number of new renewable energy source power plants. High reliability levels are as important as high yields in order to maximize the useful green energy produced. Solar energy has been one of the most popular and exploited renewable sources in the market and therefore improvements in its efficiency and reliability have had a considerable impact. All energy systems require an increase in their conversion efficiency to reduce the consumption of primary energy. Moreover, the optimization of the performance of photovoltaic systems has increased their incidence as renewable sources in global power generation and has boosted their profitability. A failure of the components and sub-components of a working energy system cause two main issues; the first direct implication for the plant is the damage of the components and sub-components, and the second indirect implication is the consequent lack of energy production due to the plant being out of order. Furthermore, unforeseen failures of the components increase the uncontrollability of photovoltaic power systems, which worsens electric grid dispatching. The work presented here provides, for the first time, a complete and new assessment of Reliability Centered Maintenance carried out using a failure mode and effect analysis approach to photovoltaic systems. We use a large volume of data derived from a database of real maintenance activities carried out by a multinational company. These data were interpreted by the opinions of experts with specialist

Particle analysis and differentiation using a photovoltaic cell

Fu, Lung-Ming; Shu, Wei-En; Wang, Yao-Nan

2012-01-01

A method is proposed for the sizing and counting of fluorescent and non-fluorescent particles of various sizes on a poly-dimethylsiloxane microchip. In the proposed approach, the detection region of the microchip is illuminated by a laser, which is then incident on a power-free photovoltaic cell. As the particles (both fluorescent and non-fluorescent) pass through the detection region, they block the laser beam, causing a reduction in the output voltage of the cell. The voltage signal is interfaced to a PC and is used to determine both the size and the number of the particles. Meanwhile, the fluorescence signal generated by the fluorescent particles within the sample is detected by an avalanche photodetector and is used to differentiate between the fluorescent and non-fluorescent particles in the sample. The effectiveness of the proposed approach is demonstrated using fluorescent-labeled beads with means diameters of 5, 8 and 10 µm, respectively, and unlabeled beads with a mean diameter of 7.2 µm. The experimental results confirm that the forward scattered light signal generated by the photovoltaic cell enables both the size and the number of the particles to be reliably determined. Moreover, it is shown that the number of non-fluorescent particles within the sample can be easily determined by comparing the signals received from the photovoltaic cell and avalanche photodetector, respectively.

Price/efficiency correlations for 2004 photovoltaic modules

International Nuclear Information System (INIS)

Green, Martin A.

2005-01-01

The claim is often made that efficiency is a key factor in determining the marketability of photovoltaic products. If this is the case, a strong correlation between the price of modules and their efficiency might be expected. This relationship is investigated using module pricing data that have recently become available. Conclusions are that there is little correlation between module price and efficiency in this data set and that some thin-film modules currently appear to attract a pricing premium. (Author)

The business potential of polymer solar cells is reviewed and the market opportunities analyzed on the basis of the currently reported and projected performance and manufacturing cost of polymer solar cells. Possible new market areas are identified and described. An overview of the present patent and intellectual property situation is also given and a patent map of polymer solar cells is drawn in a European context. It is found that the business potential of polymer solar cells is large when taking the projections for future performance into account while the currently available performance and manufacturing cost leaves little room for competition on the thin film photovoltaic market. However, polymer solar cells do enable the competitive manufacture of low cost niche products and is viewed as financially viable in its currently available form in a large volume approximation. Finally, it is found that the polymer solar cell technology is very poorly protected in Europe with the central patents being valid in only France, Germany, the Netherlands and the United Kingdom. Several countries with a large potential for PV such as Portugal and Greece are completely open and have apparently no relevant patents. This is viewed as a great advantage for the possible commercialization of polymer solar cells in a European setting as the competition for the market will be based on the manufacturing performance rather than domination by a few patent stakeholders.

Highlights: • Two-stage objective function is proposed for optimization problem. • Hourly-based optimal contractual agreement is calculated. • Scenario-based stochastic optimization problem is solved. • Improvement of system frequency by utilizing PSH unit. - Abstract: This paper proposes the operating strategy of a micro grid connected wind farm, photovoltaic and pump-storage hybrid system. The strategy consists of two stages. In the first stage, the optimal hourly contractual agreement is determined. The second stage corresponds to maximizing its profit by adapting energy management strategy of wind and photovoltaic in coordination with optimum operating schedule of storage device under frequency based pricing for a day ahead electricity market. The pump-storage hydro plant is utilized to minimize unscheduled interchange flow and maximize the system benefit by participating in frequency control based on energy price. Because of uncertainties in power generation of renewable sources and market prices, generation scheduling is modeled by a stochastic optimization problem. Uncertainties of parameters are modeled by scenario generation and scenario reduction method. A powerful optimization algorithm is proposed using by General Algebraic Modeling System (GAMS)/CPLEX. In order to verify the efficiency of the method, the algorithm is applied to various scenarios with different wind and photovoltaic power productions in a day ahead electricity market. The numerical results demonstrate the effectiveness of the proposed approach.

This system breaks down products into each evaluation factor from psychological and physical viewpoints, and carries out various kinds of multivariate analysis, thereby making it easy to understand visually, for example, what evaluation factors decide relative positional relations between evaluation factors or between products as well as the position of a product in the whole. Further, more precise marketing analysis and prediction become possible by visually grasping blank areas of products, extent of competition, distribution of products, composition of product series, etc. (translated by NEDO)

Ground-Fault Characteristic Analysis of Grid-Connected Photovoltaic Stations with Neutral Grounding Resistance

Directory of Open Access Journals (Sweden)

Zheng Li

2017-11-01

Full Text Available A centralized grid-connected photovoltaic (PV station is a widely adopted method of neutral grounding using resistance, which can potentially make pre-existing protection systems invalid and threaten the safety of power grids. Therefore, studying the fault characteristics of grid-connected PV systems and their impact on power-grid protection is of great importance. Based on an analysis of the grid structure of a grid-connected PV system and of the low-voltage ride-through control characteristics of a photovoltaic power supply, this paper proposes a short-circuit calculation model and a fault-calculation method for this kind of system. With respect to the change of system parameters, particularly the resistance connected to the neutral point, and the possible impact on protective actions, this paper achieves the general rule of short-circuit current characteristics through a simulation, which provides a reference for devising protection configurations.

Electricity market models, implemented as dynamic programming problems, have been applied widely to identify possible pathways towards a cost-optimal and low carbon electricity system. However, the joint optimization of generation and transmission remains challenging, mainly due to the fact that different characteristics and rules apply to commercial and physical exchanges of electricity in meshed networks. This paper presents a methodology that allows to optimize power generation and transmission infrastructures jointly through an iterative approach based on power transfer distribution factors (PTDFs). As PTDFs are linear representations of the physical load flow equations, they can be implemented in a linear programming environment suitable for large scale problems such as the European power system. The algorithm iteratively updates PTDFs when grid infrastructures are modified due to cost-optimal extension and thus yields an optimal solution with a consistent representation of physical load flows. The method is demonstrated on a simplified three-node model where it is found to be stable and convergent. It is then scaled to the European level in order to find the optimal power system infrastructure development under the prescription of strongly decreasing CO{sub 2} emissions in Europe until 2050 with a specific focus on photovoltaic (PV) power.

Over the past decades, climate change has been a subject of serious international negotiations. Solar photovoltaic (PV) energy has caught the eyes of many governments as one of the front-runner technologies for the low carbon energy transition in the global community. Solar PV systems have experienced strong market growth over the last decade supported by favorable political reactions in the energy transition context. However, despite these favorable conditions, paradoxically, the global PV market recently went through a chaotic time encountering the overproduction issue, the industry crisis and the long-lasting trade disputes. Furthermore, as the level of PV penetration increases, many problematics started to appear with negative systemic impacts on the electricity sector. This thesis started from these problematics to understand the PV policy mechanisms and the context change. In order to define those issues, a systemic approach is taken to provide an accurate comprehension of the overall mechanisms of PV public policies. The concrete systemic vision of PV policy mechanisms is constructed based on theoretical and historical analysis by defining key variables and the context (Part I). A retrospective analysis using the proposed mapping tools is conducted to understand critical limits and challenges of PV development and to identify risks factors in the sector (Part II). This thesis also demonstrates how the nature of policy context changes in combined with the dynamic features of the PV sector. This helps anticipate possible risks of PV development in the future. The thesis highlights the nationwide PV policy dynamics was broken with the arrival of China in the PV sector. Taken the defined critical limits and challenges into account, this thesis eventually proposes strategic orientations of PV development at the two dimensions from both national and international perspectives (Part III). At the national level, this thesis discusses on PV self-consumption as the

Recycling of photovoltaic end-of-life panels. International overview. Extended abstract

Since the early 2000's, the general awareness surrounding the importance of recycling by the users and producers of photovoltaic modules has contributed to the emergence of the end-of-life photovoltaic modules recycling activity. This awareness can be attributed to the growing concern on natural resource conservation; the natural shortage in some strategic metals used in photovoltaic; the reinforcement of regulatory framework on waste management in some countries; and the answer given to raising questions regarding the renewability of photovoltaic. In fact, the last ten years have been marked by significant research efforts, which have finally lifted the main technological barriers associated with the recycling of photovoltaic modules. Economically, the activity of recycling photovoltaic modules is not yet viable today, and is instead based on sources of compensation from the client, producer or organizations in charge of the modules collection, on top of the sale of recycled materials. Technology developers are now cautious of investment because the waste stream is still too weak and poorly controlled, the photovoltaic market is unstable, and high competitiveness is indicative of a recycling overcapacity, which could be increasingly significant by 2020. Following the definition of the study bases, the regulatory framework active in specific regions of the world is described, and an objective overview of the developing recycling sector is provided by analyzing all recycling processes, its organizational segmentation and the internal structure of relevant actors. The synthesis of this data provides a realistic guideline on the maturity of the industry and key strategies for the development of activities within this sector. Indeed, the success of this activity will rest partly on the ability of recycling actors to adapt their business model and administrative system to local regulatory framework, and adapt the size of their installation to the transitory volume

Dynamic analysis of combined photovoltaic source and synchronous generator connected to power grid

Science.gov (United States)

Mahabal, Divya

In the world of expanding economy and technology, the energy demand is likely to increase even with the global efforts of saving and increasing energy efficiency. Higher oil prices, effects of greenhouse gases, and concerns over other environmental impacts gave way to Distributed Generation (DG). With adequate awareness and support, DG's can meet these rising energy demands at lower prices compared to conventional methods. Extensive research is taking place in different areas like fuel cells, photovoltaic cells, wind turbines, and gas turbines. DG's when connected to a grid increase the overall efficiency of the power grid. It is believed that three-fifth of the world's electricity would account for renewable energy by middle of 21st century. This thesis presents the dynamic analysis of a grid connected photovoltaic (PV) system and synchronous generator. A grid is considered as an infinite bus. The photovol-taic system and synchronous generator act as small scale distributed energy resources. The output of the photovoltaic system depends on the light intensity, temperature, and irradiance levels of sun. The maximum power point tracking and DC/AC converter are also modeled for the photovoltaic system. The PV system is connected to the grid through DC/AC system. Different combinations of PV and synchronous generator are modeled with the grid to study the dynamics of the proposed system. The dynamics of the test system is analyzed by subjecting the system to several disturbances under various conditions. All modules are individually modeled and con-nected using MATLAB/Simulink software package. Results from the study show that, as the penetration of renewable energy sources like PV increases into the power system, the dynamics of the system becomes faster. When considering cases such as load switching, PV cannot deliver more power as the performance of PV depends on environmental conditions. Synchronous generator in power system can produce the required amount of

Highlights: • R sh is rather sensitive to the variations in T c . • For higher G values, G ∗ is not affected from the variations in light intensity. • Ideality factor decreases linearly with increasing T c . • A linear decrease of R s and R sh has been observed with increasing T c . • Fill factor increases exponentially with G while it decreases linearly with T c . - Abstract: It is well known that accurate knowledge of photovoltaic cell parameters from the measured current–voltage characteristics is of vital importance for the quality control and the performance assessment of photovoltaic cells/modules. Although many attempts have been made so far for a thorough analysis of cell parameters, there are still significant discrepancies between the previously published results. In this regard, a detailed investigation of cell parameters through a comprehensive experimental and statistical work is important to elucidate the aforementioned contradictions. Therefore in the present work, effects of two main environmental factors on performance parameters of mono-crystalline and poly-crystalline silicon photovoltaic modules have been experimentally investigated. The experiments have been carried out under a calibrated solar simulator for various intensity levels and cell temperatures in the range 200–500 W/m 2 and 15–60 °C, respectively. The results indicated that light intensity has a dominant effect on current parameters. Photocurrent, short circuit current and maximum current increase linearly with increasing intensity level. A new term, solar intensity coefficient, has been defined first time to characterize the solar radiation dependency of current parameters. On the other hand, it has been observed that cell temperature has a dramatic effect on voltage parameters. Open circuit voltage and maximum voltage considerably decrease with increasing cell temperature. Temperature coefficients of voltage parameters have been calculated for each case. Shunt
