Upon considering these aims, earthing systems, surge protection devices and air termination networks play a crucial role in providing lightning protection for solar power systems in line with the industry standards IEC 62305, IEC TR 63227 and IEC 61643-32, to protect against the negative impacts caused from lightning. Earthing System
A PV system installed above the protective zone offered by the existing Lightning Protection System may be at risk of receiving a direct lightning strike. This could make the existing Lightning Protection System non-compliant and provide a path for lightning currents to enter the building and endanger life.
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 investigated the induced voltages of a single panel in the laboratory.
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) .
Solar Lightning Protection is important as Lightning strikes and related electric discharge is one of the top reasons for sudden, unexpected failures of Solar systems. Lightning strikes and related electric discharge are one of the top reasons for sudden, unexpected failures of Solar systems.
Suitable measures of external lightning protection are supposed to catch direct lightning and feed it into an earthing system such that no galvanically coupled currents can have an effect on metal building installations and the PV power supply system.
