6 FAQs about [Specifications for buried lightning protection lines for photovoltaic panels]

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 ].

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.

What are the SPD requirements for an external lightning protection system?

The SPD (Surge Protection Device) requirements for a photovoltaic system that is protected by an external lightning protection system (LPS) depend on the selected class of the LPS and whether the separation distance between the LPS and the PV installation is isolated or non-isolated [4].

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 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.

How does indirect lightning affect solar PV systems?

Indirect lightning strikes can easily damage the sensitive components within solar PV systems, leading to high repair or replacement costs and decreased system reliability [1]. The overvoltage experienced by the PV system depends on its specific setup and wiring conditions.
