BLOCKING AND BYPASS DIODES IN SOLAR PANELS AND SOLAR PV

Bypass diodes are used to reduce the power loss of solar panels'' experience due to shading. Cause current flows from high to low voltage when a solar panel has cells that are partially shaded. The current is then forced through the low voltage shaded cells. This causes the solar panel to heat up and have some power loss.

Solar Panel Shading Problems & Solutions

When a portion of a solar panel is shaded, the shaded cells will produce less power (low current). Meanwhile, the unshaded cells will be producing full power (high-current), and a reverse current situation will occur where the current can flow back into the shaded cells, resulting in overheating of the cell.
