Are PV systems vulnerable to lightning?

Similar to other power systems [ , , , , ], PV systems are vulnerable to lightning because they are always installed in unsheltered open areas. Recent studies on lightning protection of PV systems have drawn much attentions [ 9 ].

Is lightning protection necessary for PV systems?

Consequently, effective lightning protection is indispensable for PV systems. Lightning transient evaluation of a PV system has been a necessary task in designing effective LPS. Such evaluation has been addressed experimentally and numerically. Stern and Karner [ 10] investigated the induced voltages of a single panel in the laboratory.

Why do PV systems need a lightning rod?

Firstly, due capital cost of installing a large-scale grounding grid is high. system. Moreover, due to the presence of independent lightning causes signiﬁcant damages to the PV systems. In this part, we PV system in the presence of an independent lightning rod.

Are residential PV systems a lightning target?

Residential PV systems are generally installed on the rooftop of residential buildings, with a large metal surface area, higher distance from the ground and an exposed location. Such PV systems are therefore potential lightning targets during thunderstorms.

What is lightning induced voltage in a photovoltaic system?

Simulation of surges in a photovoltaic system Lightning induced voltages in DC cables is one of the critical issues in lightning protection of PV systems. This voltage may damage the inverter connected to the DC cable. The induced voltage on the PV panel could damage bypass diodes connected to the panel as well.
