6 FAQs about [Lightning protection design for rooftop photovoltaic panels]

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.

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.

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.

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.

How will a lightning protection system affect PV power generation?

All this kind of destruction will undoubtedly affect the economic aspects or the return on investment that could be earned from PV power generation as well as the cost of repair or replacement to recover from the damage, all of which can be mitigated by implementing a lightning protection system (LPS) .
