Blocking Diode and Bypass Diodes in a Solar Panel Junction Box
There are two types of diodes are used as bypass diode in solar panels which are PN-Junction diode and Schottky diode (also known as Schottky barrier diode) with a wide range of current rating. The Schottky diode has lower forward voltage drop of 0.4V as compared to normal silicon PN-Junction diode which is 0.7V.
