The importance of properly grounding your solar energy equipment cannot be overstressed, as static and lightning can result in costly repairs. A solar ground fault will help you properly ground your solar energy system. Grounding requires that your solar energy system be connected to the earth electrically. This reduces the attractiveness of your system to lightning, creates a safe path for lightning in the case of a strike, reduces electrical hum caused by equipment, and reduces the hazard of potential shock from the high voltage parts of your system. It is also required by the National Electrical Code for all solar installations.
