Extended thermal cycling of PV modules. Test procedure1 Scope This document defines a test sequence that extends the thermal cycling test of IEC 612152. It is intended to differentiate PV modules with improved durability to thermal cycling and evaluate modules for deployment in locations most susceptible to thermal cycling type stress 1. This document is based on the ability for 95 % of the modules represented by the samples submitted for this test to pass an equivalency of 500 thermal cycles, as defined
