In order to avoid faults and equipment's damages that lead to severe effects, the lightning protection in PV installations is very important and practically needed..
A: Yes, due to their sensitivity and the risks associated with lightning, solar energy systems should always be equipped with effective lightning protection..
PV systems are at high risk of lightning strikes due to their installation in exposed locations and must therefore be protected against surges in accordance with EN 61643-32..
