Potential Induced Degradation Outdoor Testing

Methodology

The I-V PID Outdoor bench allows photovoltaic modules to be placed under Potential Induced Degradation (PID) stresses in natural conditions. It makes it possible to detect any degradation of the performance of the modules through acquisition of I-V curves before and after the PID sequence.
