6 FAQs about [Lightning protection requirements for photovoltaic brackets]
Do PV systems need lightning protection?
With all the barriers discussed in Section 3.3, the need for lightning protection on PV systems must be evaluated on the basis of the risk analysis and protection costs. Table 10 presents the recommended standards related to PV systems including PV installations, lightning protection systems and electrical installations. Table 10.
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 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.
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 ].
Does a PV generator need a lightning protection system?
If there is a lightning protection system (LPS) already installed, the PV generator should be integrated into the LPS according to IEC 62305-3. Even if there is no LPS installed, overvoltage protection may still be required to protect the PV generator and the power conversion unit.
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.
