What is potential induced degradation (PID) in solar panels?

Potential Induced Degradation (PID) is a phenomenon that occurs when part of the electricity in the panel moves through the coating, encapsulant material or frame rather than flowing along the defined path. As its name suggests, PID can cause degradation in efficiency and output. PID in solar panels results from several factors.
