Development of comparative tests of PV modules by the International PV Module QA Task Force

The International Photovoltaic (PV) Module Quality Assurance Task Force (PVQAT) was created in 2011 to develop a rating system that provides comparative information about the relative durability of PV modules. The identification of accelerated stress tests that can provide such comparative information is seen as a major step toward being able to predict PV module service life. This paper provides details of the ongoing effort to determine the format of such an overall module rating system.
