Photovoltaic grounding is a key element of a photovoltaic system, ensuring its safety and reliability. It involves connecting the metal components of the installation to the ground using grounding wires, which effectively dissipates unwanted electrical charges. However, the grounding process and methods differ slightly, offering multiple options, such as separate grounding or combined grounding. The distinction between these two systems is primarily based on how the solar array is connected to the ground reference. . All PV equipment must be grounded per NEC 250. UL 2703 listed racking systems bond. .
