Lightning Protection and Earthing Coordination in Solar PV Systems

Solar photovoltaic (PV) installations are often exposed, elevated, and spread across large rooftop or ground-mounted areas, making them inherently vulnerable to lightning activity. To mitigate this risk, a Lightning Protection System (LPS) must be carefully coordinated with the solar PV earthing system. The image illustrates best-practice principles for bonding, separation, Read more…

Earth Resistance Testing in Solar PV Systems: Methodology, Safety, and Compliance

An effective earthing system is only as good as its measured resistance. In solar photovoltaic (PV) installations, earth resistance testing is a mandatory commissioning and maintenance activity that verifies whether fault currents can safely dissipate into the ground. The image illustrates the three-point fall-of-potential method, the most widely accepted technique Read more…
