The International Photovoltaic Quality Assurance Task Force's module durability efforts focus on testing for elements that significantly contribute to wear, fatigue, and stress in PV modules.
PVQAT is proposing a test that will differentiate three climates (desert, tropical, and temperate) and two use environments (open rack and close-roof mount). This test protocol is being discussed by the IEC for consideration as IEC 62892.
PVQAT has ongoing research projects to guide the writing of IEC 62892-1, "Testing of PV modules to differentiate performance in multiple climates and applications – Part 1: Requirements for testing."
