Bypass Diodes in Solar Panels
Bypass diodes are quite similar to the diodes that are used in the solar cells where the bypass diodes allow greater amount of current to pass through them with a very little amount of losses in them. In general, bypass diodes are arranged in reverse bias between the positive and negative output terminals of the solar cells and has no effect on its output. …
