What does it mean to ground a photovoltaic panel
Grounding (also known as earthing) is the process of physically connecting the metallic and exposed parts of a device to the earth. It is a mandatory practice required by NEC and IEC codes to protect both equipment and personnel from damage and electric shock hazards. The purpose of grounding is to create a safe path for electric current to flow in case of a fault, such as a short circuit or lightning strike.
