The European Commission also participates in the work of the Agency. The IEA Photovoltaic Power Systems Programme (IEA-PVPS) is one of the collaborative research and development (R&D) agreements established within the IEA. Since 1993, its participants have conducted a variety of joint projects in the applications of photovoltaic (PV) conversion of solar energy into electricity. The 19 participating countries are Australia (AUS), Austria (AUT), Canada (CAN), Denmark (DNK), France (FRA), Germany (DEU), Israel (ISR), Italy (ITA), Japan (JPN), Korea (KOR), Mexico (MEX), The Netherlands (NLD), Norway (NOR), Portugal (PRT), Spain (ESP), Sweden (SWE), Switzerland (CHE), The United Kingdom (GBR), and The United States of America (USA). The European Commission and the European Photovoltaic Industry Association are also members. The overall programme is headed by an Executive Committee composed of one representative from each participating country, while the management of individual research projects (tasks) is the responsibility of Operating Agents. Ten tasks have been established and six are currently active. Information about these tasks can be found on the public Web site www.iea-pvps.org. A new task concerning PV environmental safety and health is now being developed. The objective of Task 1 is to promote and facilitate the exchange and dissemination of information on the technical, economic, environmental, and social aspects of photovoltaic power systems. Version 14 3 of 42 Revised August 2007 ii Introduction The objective of Task 1 of the IEA Photovoltaic Power Systems Program (PVPS) is to facilitate the exchange and dissemination of information on the technical, economic, environmental and social aspects of photovoltaic power systems. An important deliverable of Task 1 is the annual International Survey Report on photovoltaic power applications. This report gives information on trends in photovoltaic power applications in the 19 member countries and is based on the information provided in the National Survey Reports, which are produced annually by each Task 1 participant. The public PVPS Web site also plays an important role in disseminating information arising from the program, including national information. Version 14 4 of 42 Revised August 2007 1 Executive summary The United States’ National Survey Report (NSR) summarizes some of the key indicators of the national photovoltaic (PV) industry’s progress. These indicators include manufacturing and installation data, policy developments, and national progress in research and development (R&D). However, the U.S. NSR does not cover the global progress being made in the PV industry. The International Energy Agency (IEA) Photovoltaic Power Systems Programme (PVPS) Trends in Photovoltaic Applications provides an overview of applications and markets for PV power systems in the reporting countries at the end of 2006 and analyzes trends in implementing PV power systems. Please visit www.iea-pvps.org to obtain an electronic copy of the report. In 2006, the United States’ PV industry witnessed significant progress on the following fronts: • The implementation of new and aggressive R&D efforts between the U.S. Department of Energy (DOE) Solar Energy Technologies Program, industry, and university partners through the Solar America Initiative (SAI) (www.eere.energy/gov/solar/solar_america/), which is part of the President’s Advanced Energy Initiative. • Increased interest in educational efforts by non-governmental organisations (NGOs) and for-profit organisations to support the market acceptance of solar technologies. • Increased interest by the investment community in solar energy technologies as part of the clean technology investment movement. • Expansion of U.S. manufacturing capacity by many PV manufacturers to meet the ongoing global demand for PV. • Growing political interest in alternative energy sources, such as PV, as a way to hedge against volatile fuel prices, protect the environment, and diversify energy sources. As a result of growing concerns, more local and state governments are enacting policies to promote renewable energy applications. A summary of 2006 progress follows: Cell and Module Production U.S. global cell production increased 30.9 % to 201.6 MWdc in 2006, from 154.0 MWdc in 2005. As the numbers will indicate in this year’s NSR, U.S. solar cell producers had a difficult year in 2006 due to the limited access to polysilicon feedstock. Nearly all of the increase in U.S. cell production in 2006 came from First Solar, with 60 MW of thin-film PV. Module production increased 31 % to 202 MW. U.S. PV cell and module production totaled 202 MW in 2006—a 31 % increase from 2005. Merger and acquisition activity and increased debt financing allowed several companies to expand cell and module production capacity in the United States. Version 14 5 of 42 Revised August 2007 Installations Installations in the United States increased 40 %, from 105 MW in 2005 to 145 MW in 2006. Most of the growth occurred in the grid-connected sector—from 70 MW in 2005 to more than 106 MW in 2006. Costs and Prices The installed cost of grid-connected PV systems remained nearly constant at $7.00–8.00 / Wac U.S.
