6 FAQs about [Lightning protection design for photovoltaic support roof]

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.

Do PV systems need lightning protection?

With all the barriers discussed in Section 3.3, the need for lightning protection on PV systems must be evaluated on the basis of the risk analysis and protection costs. Table 10 presents the recommended standards related to PV systems including PV installations, lightning protection systems and electrical installations. Table 10.

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.

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 ].

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.

What is a lightning protection system?

Complete system used to reduce the danger of physical damages or injury caused by direct lightning strikes to a structure. It consists of air termination devices, down conductors and earthing electrodes.
