The NFPA and IEEE recommend a ground resistance value of 5 ohms or less while the NEC has stated to “Make sure that system impedance to ground is less than 5 ohms specified in NEC 50. In facilities with sensitive equipment it should be 5ohms or less”. This process involves two distinct but related concepts: system grounding, which provides a reference to earth for the electrical system (stabilizing. . Grounding a solar photovoltaic (PV) system involves establishing a low-resistance conductive pathway that connects the non-current-carrying metal components of the array to the earth. Yet, grounding is often misunderstood, with common errors leading to system failures and safety hazards. Bonding connects metal equipment parts together to establish electrical continuity and prevent electric shock. Most solar installation inspections fail due to improper grounding and bonding. All PV equipment must be. . Abstract—This paper presents basic guidelines on design considerations for large utility-scale photovoltaic (PV) solar power plant (SPP) substation and collector grounding systems for safety aspects.
