6 Frequently Asked Questions about “Lightning protection for solar panels on building roofs”
Do rooftop photovoltaic systems need a lightning protection system?
This guideline also requires that LPL III and thus a lightning protection system accord-ing to class of LPS III be installed for rooftop PV systems (> 10 kWp) and that surge protection measures be taken. As a general rule, rooftop photovoltaic systems must not interfere with the existing lightning pro-tection measures.
Does a lightning protection system need to be installed on a building?
The energy released by a lightning discharge is one of the most frequent causes of fire. Therefore, personal and fire protection is of paramount importance in case of a direct lightning strike to the building. At the design stage of a PV system, it is evident whether a lightning protection system is installed on a building.
Can Lightning affect a roof top PV system?
It has been shown that for buildings with roof top PV systems only the avoidance of lightning attachment to unprotected parts of the building is not sufficient. Lightning currents passing through the lightning protection system may still affect the PV power system through inductive coupling.
How to protect solar power systems from lightning?
Upon considering these aims, earthing systems, surge protection devices and air termination networks play a crucial role in providing lightning protection for solar power systems in line with the industry standards IEC 62305, IEC TR 63227 and IEC 61643-32, to protect against the negative impacts caused from lightning.
