Is there a diode in the junction box on the back of the solar panel?

The conventional diode in the junction box is a by-pass diode, which is mainly to prevent the damage of the solar panel caused by the hot spot effect caused by partial shading; Bypass diodes are installed for panels greater than or equal to 75W, and can also be customized according to customer requirements.
