Earthing is a way of making sure that electricity doesn't flow off your equipment randomly and becomes a safety hazard. It introduces a shortcut to any potential leakage of electricity, which is ground, to provide a safe path to discharge. If earthing (also known as grounding) is ignored during the system installation.
Before we go into the topic of grounding, let's define the term “grounding.” In electrical and PV systems, there are two forms of grounding:.

Why Ground Solar Panels? Grounding solar panels is necessary because: It reduces built up charge, making your system less attractive to lightning. If a charge builds or lightning hits, the discharge will go into the earth instead of your cable. Without grounding this will not happen. Grounding minimizes power shock from high voltage components.
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).
