Potential Induced Degradation (PID) Explained: Causes and Fixes

Potential induced degradation (PID) is a voltage-driven loss of photovoltaic module performance caused by leakage currents between solar cells and grounded module hardware. Depending on cell design and materials, PID can create cell shunting, surface polarization, or passivation loss, reducing power, fill factor, and sometimes open-circuit voltage. Recovery may be possible when the mechanism is […]
