Photovoltaic panels allow for the efficient use of solar energy and significantly reduce electricity bills. However, for the entire installation to operate safely and efficiently, proper grounding of the photovoltaic system is crucial.
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.
Section 250 of the NEC specifically deals with grounding electrical systems, including solar panel installations. Key points from the NEC: The code requires all non-current-carrying metal parts of the solar PV system to be grounded. It specifies the minimum size of grounding conductors (more on this later).
Typically, in a solar power system, the grounding is done on the negative side. This is known as a “negative grounding” system. Grounding the negative side minimizes the risk of electrical shock if the system were to come into contact with a person or any conductive material.
