Tests were carried out on each of five major causes of performance degradation of a solar module over time – thermal cycling, dynamic mechanical load stress, humidity freeze conditions, damp heat exposure, and potential-induced degradation.

The 2016 PV Module Reliability Scorecard aims to address the lack of publicly available long-term data on the reliability of solar PV modules. In addition, field data takes many years to collect and by that time the technology has evolved.

The
