All PV equipment must be grounded per NEC 250. Modern solar installations use several key safety components. Bonding connects metal equipment parts together to establish electrical continuity and prevent electric shock. Solar ABCs, with support from the U. Department of Energy, commissioned this report to provide the PV industry with practical. . When it comes to grounding requirements for solar panels, you must meet the stringent guidelines that are central to your project. Failure to secure a solar panel grounding system not only creates potential safety issues, but can result in additional expense, penalties and rework. However, the grounding process and methods differ slightly, offering. . Exposed metal parts of PV module frames, electrical equipment, and enclosures containing PV system conductors must be connected to the PV system circuit equipment grounding conductor complying with 690. }Figure 690–79 }Figure 690–79. .
