What is a hot spot effect in a PV module?

3. The mechanism of hot spot effect Hot spot heating occurs in a PV module when its operating current exceeds the reduced short-circuit current (Isc) of a shadowed or faulty cell or group of cells. When such a condition occurs, the affected cell or group of cells is forced into reverse bias and dissipates power, which can cause local overheating.

Why is hot spotting a problem for PV panels?

Hot spotting is a reliability issue in photovoltaic (PV) panels where a mismatched cell heats up significantly and degrades PV panel output power performance.
