Voltage and Time Dependence of the Potential Induced Degradation(PID)

Since the generation of solar energy is increasing and getting important worldwide .PV systems is becoming bigger with increasing the amount of serially interconnected panels. These panels are exposed to high potential relative to the ground which causing high voltage stresses (HVS). This HVS causing instability of the solar panels depending on some factors which cause an unwanted property called potential induced degradation (PID). The factors which effect on the PID are (Voltage, humidity and high temp) which generate leakage current between the solar cells and the ground. The key is to understand the PID phenomenon and the leakage current property which still not understandable.
