6 FAQs about [Lightning protection circuit for photovoltaic panels]
How to protect PV panels during lightning strikes?
Therefore, an adequate lightning protection system (LPS) must be installed to protect the PV panels. In addition, the transient performance of PV panels during lightning strikes must be analyzed well. This paper presents a comprehensive review of the superior modeling methods of PV systems during lightning strikes.
Are photovoltaic systems exposed to lightning?
1. Introduction Photovoltaic systems are inherently exposed to direct and indirect lightning effecfs. For high- capacity systems, the deployment of solar cell arrays requires a large area with commensurate exposure to direct lightning strikes at the local annual rate of ground strikes per unit area.
How does Lightning affect a PV system?
After studying the influences of lightning strikes on the PV system and modeling methods, it is mandatory to design a protection system for the PV system during lightning. The lightning protection system (LPS) is used to protect the PV system from damage and service interruption.
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 ].
How to protect a PV system from lightning discharges?
In case that a PV installation is protected against lightning discharges by an external LPS, the above distance s between the PV equipment and the parts of the LPS should be respected, in order to avoid sharing of discharge currents through the metallic components of the PV system.
