6 FAQs about [Photovoltaic panel lightning protection welding method]

Do PV panels need a lightning protection system?

Consequently, they are frequently subjected to lightning strikes, which may cause damage to PV arrays, service interruption, and additional cost for PV replacement. Therefore, an adequate lightning protection system (LPS) must be installed to protect the PV panels.

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.

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 PV system in case of indirect lightning?

A proposed design of SPD to protect the PV system in case of indirect lightning was explained [ 40 ], where the designed hardware was type 2 SPD. This type consists of varistor, Zener diode, common mode choke, transient voltage suppresser (TVS), and gate discharge tube (GDT).

Why is lightning protection important for PV systems?

damaged by lightning strikes largely reduces the return of investment because it incurs disassembly cost and transportation cost. The component failures affe ct the continuity of the power supply as well. Consequently, effective lightning protection is indispensable for PV systems.

Do lightning currents affect PV power system through inductive coupling?

Lightning currents passing through the lightning protection system may still affect the PV power system through inductive coupling. Hence strategic placement of PV systems and shielding of conducting systems wherever possible has been recommended.
