6 FAQs about [Photovoltaic panel lightning protection level classification table]

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 ].

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.

What is lightning protection level?

Lightning protection level is used to design protection measures according to the relevant set of lightning current parameters. Complete system used to reduce physical damage due to lightning flashes striking a structure. It consists of both external and internal lightning protection systems.

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.

What is the protection level for a PV power station zone?

Depending on the result of the calculations and considering the N G value, the protection level for a selected PV power station zone can be LPL III. or IV. or no external protection. The physical structure, e.g., the distance and height of the air-termination rods, is defined in the standard for each LPL level 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) .
