Why Bypass Diode Is Used In Solar Panel. Diodes are extensively used in solar panel installations. Feel free to ask any doubts regarding this video.
So when buying a less expensive solar panel make sure there is a bypass diode in the junction box. The bypass diodes are usually placed on sub-strings. Ideally there would be one bypass diode for each solar cell but this can be rather expensive so generally one diode is used per small group of series cells.
It also prevents the current from other panels which are working at high potential to flow back to the faulty panel at low potential.
Thus even when a panel is faulty the bypass diode still makes the whole solar system run and produce electricity at a lower rate. Generally the PN Junction diodes are used in solar panels. Thus even when a panel is faulty the bypass diode still makes the whole solar system run and produce electricity at a lower rate. Bypass Diode in solar Panel explained.
