Since solar cells are a type of photodiode and a source of constant current, the positive and negative electrodes can be shorted. Once the electrodes are shorted, a typical insulation meter can accurately measure the insulation resistance. A conductor with good insulation will have high resistance, and poor insulation will have low resistance. . Solar panels endure harsh conditions—UV exposure, temperature extremes, and moisture—all of which degrade insulation over time. When measuring the insulation resistance of a solar panel that is actively generating electricity, it is essential to avoid using conventional methods designed for standard circuits.
