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.

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 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) .

How to protect a PV system from lightning discharges?

In case that a PV installation is protected against lightning discharges by an external LPS, the above distance s between the PV equipment and the parts of the LPS should be respected, in order to avoid sharing of discharge currents through the metallic components of the PV system.

Are lightning protection systems effective?

Experience shows that where lightning protection systems are installed, more often than not their design is poor and the protection they provide, ineffective. The problem becomes more serious for the industry, as the number of photovoltaic power plants increases.

Can lightning damage PV panels?

The outcome indicated that the efficiency of the PV panel could be reduced as well as the panels may suffer physical deterioration caused by the high lightning impulse voltage/current. Many PV systems may not be properly protected against lightning.
