6 FAQs about [The distance between the lightning protection belt and the photovoltaic panel]

Can a PV mounting system carry a lightning current?

The metal components of the PV mounting system must be connected to the external lightning protection system in such a way that they can carry lightning currents (cop-per conductor with a cross-section of at least 16 mm2 or equivalent).

Does a lightning protection system work on a grid-connected photovoltaic park?

In this paper, the performance of a lightning protection system (LPS) on a grid-connected photovoltaic (PV) park is studied by simulating different scenarios with the use of an appropriate software tool.

How vulnerable are photovoltaic systems to lightning strikes?

Photovoltaic systems are vulnerable to both direct and indirect lightning strikes. Therefore, they must be built with reliable and properly installed surge protection. (References: [1] Lightning Protection Guide, DIN EN Standard 62305-3, 2014. [2])

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.

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.

Why are PV systems more vulnerable to lightning?

2. Protection of PV Systems against Lightning Overvoltages As it is described in [4, 19], PV modules are more vulnerable to direct lightning strikes than conventional low-voltage power distribution systems, due to installation on roofs, facades of buildings, and, in general, on unsheltered areas.
