Introduction Understanding Potential Induced Degradation Contents

Potential Induced Degradation (PID) is an undesirable property of some solar modules. The factors that enable PID (voltage, heat and humidity) exist on all photovoltaic (PV) systems, but the effect does not occur on all or even most PV systems. According to Dr. Peter Hacke of the National Renewable Energy Laboratory (NREL), “All c-Si [crystalline silicon… CONTINUE READING
