What is the role of lightning arrestor in solar PV systems?

Lightning can strike anywhere at any time without warning & it can be destructive even when if it does not strike directly. The energy released by a lightning discharge is one of the most common causes of fire. Therefore, personal and fire protection is of utmost importance in case of a lightning strike to the building.

Lightning arrestors are designed to absorb voltage spikes caused by electrical storms, and effectively allow the surge to bypass power wiring and the PV system.
