Hot Spots

Hot Spots

A hot spot condition exists when a solar cell within a panel generates less current than the string current of the panel. Some of the leading causes are shading, damage or electrical mismatch of cells and panels. Bypass diodes are a now standard in crystalline panels. The bypass diode’s core function is to eliminate hot spots forming, preventing damage to the panel and making the panel safer with less risk of fire. This enables the panel to operate with higher reliability over its lifetime.
