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. . There are several key grounding codes and standards you should consider when undertaking any solar panel project. . Therefore, you must ground solar with the right wire sizes. Article 690 of the NEC mandates that #8 AWG or #6 AWG are the smallest wires that can be used with grid tied solar panels and inverter systems, and for solar panel output circuits, #10 or #12 AWG are allowed. The distinction between these two systems is primarily based on how the solar array is connected to the ground reference.
