6 FAQs about [How to test the lightning protection of photovoltaic panels]

Do PV systems need lightning protection?

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 ].

How do I protect my PV system from lightning strikes?

To protect your PV system from direct lightning strikes, steps should be taken to ensure that the system is incorporated into the protective zone of the existing air termination system*. Additionally,* the correct surge and lightning equipotential bonding SPD’s should be installed where required on incoming services. In order to avoid this, the PV system should be protected.

How does Lightning affect PV systems?

Hence strategic placement of PV systems and shielding of conducting systems wherever possible has been recommended. It has also been envisaged that the impact of lightning on PV systems is directly related to the isokeraunic level of the region and elevation of the building.

Does a PV generator need a lightning protection system?
