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.
It is a mandatory practice required by NEC and IEC codes to protect both equipment and personnel from damage and electric shock hazards. This article covers grounding in PV systems, which differs slightly from standard grounding systems.
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.
