What is earthing and why is it important in a rooftop solar power plant?

Earthing refers to a safety system designed to protect electrical wires and components from damage caused by sudden electrical power surges. The aim of earthing in electrical installations and circuits is to enhance the safety of the installation by reducing the level of danger inherent to fault currents.

Fault currents may be caused by different factors. Therefore, it is very important to design an earthing system according to the installation’s characteristics.

 Earthing system is important because it provides:
– Safety for humans from electric shocks;
– Protects the installation and equipment itself from any damage;
– Safety from atmospheric electricity (lightning) etc.
