In this article, you will learn how to protect your solar power system from lightning. Drawing from decades of installer experience, we’ll explore the most cost-effective techniques generally accepted by power system installers. Grounding is the most fundamental technique for protection against lightning damage.
This guideline also requires that LPL III and thus a lightning protection system accord-ing to class of LPS III be installed for rooftop PV systems (> 10 kWp) and that surge protection measures be taken. As a general rule, rooftop photovoltaic systems must not interfere with the existing lightning pro-tection measures.
Lightning is a common cause of failures in photovoltaic (PV) and wind-electric systems. A damaging surge can occur from lightning that strikes a long distance from the system or between clouds. But most lightning damage is preventable. In this article, you will learn how to protect your solar power system from lightning.
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) .
If the mounting system is directly connected to the external lightning protection system due to the fact that the separa-tion distance s cannot be maintained, these conductors be-come part of the lightning equipotential bonding system. Consequently, these elements must be capable of carrying lightning currents.
Many PV systems may not be properly protected against lightning. Due to this exposure, the PV systems may be liable to suffer a crucial impact in a way that can lead towards severe damage for instances; failure of the electrical and electronic parts in the building or PV installation and disruption of their normal operation.
