Similarly, this guide does not directly cover small scale solar power plants (such as rooftop type systems), substation grounding, or lightning protection. Scope: This guide is primarily concerned with the grounding system design for ground-mount photovoltaic (PV) solar power plants (SPPs) that are utility owned and/or utility scale (5 MW or greater).
Lightning is a common natural phenomenon observed on earth and it is even visible from outer space. In fact, it is also recognized as the most fatal natural phenomenon since it can be catastrophic to mankind .Generally, lightning is a transient, high-current electric discharge whose path length is measured in kilometres.
For solar panels, grounding involves installing grounding rods, wires, and straps to create a continuous path to move electrical charges into the earth. To properly ground solar panels, you can follow these steps: 1. Install Grounding Rods. Bury many copper-coated steel grounding rods at least 6 to 8 feet apart around the solar panel installation. Bury the rods at
