6 FAQs about [Causes of Lightning Protection Failure of Photovoltaic Inverter]

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.

Why is lightning a major threat to photovoltaic (PV) systems?

Lightning is one of the major threats to photovoltaic (PV) systems, due to their typically unsheltered installations. This problem is getting more and more relevant as installed systems with larger areas are getting common in response to the increased PV energy demand .

What causes system failures in PV plant during a lightning strike?

System failures in the PV plant during a lightning strike may be caused by the failure of PV inverters, breakdown of bypass diodes, arcing between PV frame and wires, and others. A power inverter plays a vital role in energy conversion in the PV system. It transforms the DC power generated by the PV modules into three-phase AC power.

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 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.

Do lightning-induced voltages cause damage to PV systems?

With the PEEC method, lightning-induced voltages in the PV system were simulated. Significant overvoltages were observed and could cause damages to the PV systems, if protection measures were not provided appropriately. Simulation results were generally consistent with the field observation reported in the literature in some cases.
