This Solar America Board for Codes and Standards (Solar ABCs) report addresses the requirements for electrical grounding of photovoltaic (PV) systems in the United States. Solar ABCs, with support from the U. This process involves two distinct but related concepts: system grounding, which connects current-carrying conductors to the earth for voltage. . 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. Grounding connects electrical components to Earth at zero voltage potential. Failure to secure a solar panel grounding system not only creates potential safety issues, but can result in additional expense, penalties and rework. The NEC is the primary guiding document for the safe designing and installation practices of solar PV systems in the residential and commercial markets in the. .
