This involves bonding all metallic components of the PV array (modules, racking, inverters) together and connecting them to the grounding electrode system. The goal is to ensure that in the event of a ground fault, a large enough current will flow to quickly open the. . Properly grounding solar PV systems is one of the most critical aspects of a safe and reliable installation, governed by Part V of NEC Article 690. This process involves two distinct but related concepts: system grounding, which connects current-carrying conductors to the earth for voltage. . Grounding means connecting electrical components to the ground or Earth. The 2020 National Electrical Code (NEC) Section 250. It's not just a box to tick off during installation – it's a vital step that protects your investment and ensures your system operates efficiently. Failure to secure a solar panel grounding system not only creates potential safety issues, but can result in additional expense, penalties and rework.
