6 FAQs about [Lightning protection requirements for photovoltaic power station panels]

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 there standards for lightning protection system installation?

No doubt that there are standards govern the lightning protection system installation for building and the solar PV itself which can be obtained from the International Electrotechnical Committee (IEC) and various other national and international standards, respectively.

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) .

Can lightning damage PV systems?

However, the knowledge of appropriate design and installation of lightning protection systems (LPS) are still under research. It has been reported that averagely 26% damage of PV systems is caused by lightning strikes [ 9 ]. This figure could be higher in the areas with severe lightning storms.

Is lightning transient evaluation of a PV system necessary?

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. An inductive coupling model for PV panels was also proposed to assist the design.

Can a lightning strike prevent a PV panel?

Experimental on a direct lightning strike to a PV panel were conducted. When a frame is grounded, a surface discharge occurs and it might be able to prevent direct lightning strikes against the PV panel. The PV damage caused during a lightning strike.
