6 FAQs about [Photovoltaic inverter input lightning protection circuit]

What is lightning induced voltage in a photovoltaic system?

Simulation of surges in a photovoltaic system Lightning induced voltages in DC cables is one of the critical issues in lightning protection of PV systems. This voltage may damage the inverter connected to the DC cable. The induced voltage on the PV panel could damage bypass diodes connected to the panel as well.

How does indirect lightning affect solar PV systems?

Indirect lightning strikes can easily damage the sensitive components within solar PV systems, leading to high repair or replacement costs and decreased system reliability [1]. The overvoltage experienced by the PV system depends on its specific setup and wiring conditions.

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 vulnerable are photovoltaic systems to lightning strikes?

Photovoltaic systems are vulnerable to both direct and indirect lightning strikes. Therefore, they must be built with reliable and properly installed surge protection. (References: [1] Lightning Protection Guide, DIN EN Standard 62305-3, 2014. [2])

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.

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) .
