How to Check Solar Panel Polarity

One way to find reverse polarity on solar panels is by looking for open circuits. If your PV modules are wired right (with positive and negative leads connected), you shouldn''t have any issues with open circuits. However, if one lead of a terminal in the DC circuit breaker box is connected while the other isn''t, it creates an open circuit.
