How to add diodes to solar cells
Bypass Diode in a solar panel is used to protect partially shaded photovoltaic cells array inside solar panel from the normally operated photovoltaic string in the peak sunshine in the same PV panel. They allow current to flow around a shaded cell, ensuring that the rest of the system is not affected.
