Abstract

To ensure the longevity and reliability of solar modules, the PV industry has adopted a series of accelerated aging tests. Among these, the damp heat test performed at 85°C, 85% relative humidity for 1000 hrs provides the most information on the degradation of encapsulant and backsheet materials. The purpose of this work is to define the proper accelerated test conditions that represent 25 years of real field life exposure of these polymers.
