Bypass Diodes & Blocking Diodes in Solar Panels

Bypass diodes are used to reduce the power loss solar panels experience due to shading. Because 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 severe power loss.

Bypass Diodes Explained

Typical solar panels only have two bypass diodes, one every 18-24 cells. So if a cell on the panel is blocked, the bypass diode skips the entire string of cells. Sometimes a whole panel can be knocked out and not produce energy if two cells in different rows are shaded or blocked. Array''s solar modules have bypass diodes on …
