When exposed to sunlight (or other intense light source), the voltage produced by a single solar cell is about 0.58 volts DC, with the current flow.Reverse polarity occurs when the positive and negative wires of a solar panel are connected to the wrong terminals of a battery or other electrical device.

Reverse polarity occurs when the positive and negative wires of a solar panel are connected to the wrong terminals of a battery or other electrical device.

This use of bypass diodes in solar panels allows a series (called a string) of connected cells or panels to continue supplying power at a reduced voltage rather than no power at all. Bypass diodes are connected in reverse bias between a solar cells (or panel) positive and negative output terminals and has no effect on its output.
