Predicting PV module service life

The International PV Module Quality Assurance Task Force 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 will describe the methodology being employed by the Task Force as well as the efforts of the Ten Task Groups formed by the Task Force. Since this is an ongoing effort, this paper will serve as a progress report.
