2006, according to the International Energy Agency.Total PV cell production in 2006 was reported to be about 1 900 megawatts, an increase of 27 % from 2005. Global demand for PV exceeds USD 5 billion annually. As its uses have multiplied and the industry has grown, PV has proved to be one of the most reliable sources of electricity. Indeed, PV modules now come with long-term warranties. But these promises of durability and reliability raise questions about the quality of PV components, systems, installations and after-sales maintenance among customers. The IEC’s International Standards for PV and its Worldwide System for Conformity Testing and Certification of Electrotechnical Equipment and Components (IECEE) provide both benchmarks and proofs of quality for industry and government.

# F1 _3 i6 ]+ w$ l% {* PThe worldwide PV community, including national and regional PV industry associations, and supported by such international organizations as The World Bank and the United Nations Development Programme, decided to institute a high-priority program to offer a truly global quality assurance solution. In order to achieve this goal and to guide the PV industry, especially in developing countries, PV GAP – a notfor-profit international organization dedicated to the sustained growth of global PV markets to meet energy needs – decided in 2008 to transfer ownership of the PV GAP Mark and Seal to the IECEE.9 K: C7 T+ S9 [
