6 FAQs about [Lightning protection and grounding of roof photovoltaic bracket]
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 a lightning protection system be installed on a flat roof?
If a system is installed on a flat roof, it tends to ground via the inverter cover or connect to the building’s existing lightning protection system. Such lightning protection is potentially inadequate for areas with high lightning probability.
Why is a mounting system connected to an external lightning protection system?
If the mounting system is directly connected to the external lightning protection system due to the fact that the separa-tion distance s cannot be maintained, these conductors be-come part of the lightning equipotential bonding system. Consequently, these elements must be capable of carrying lightning currents.
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.
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.
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.
