The erection of conventional PV power supply systems on or at buildings does not change the lightning strike risk. It is recommended to design and harmonize the PV power supply and lightning protection systems before erection. The PV generator delivers current and voltage even at low amounts of solar irradiance. This has to be taken into
The lightning damages increases in Photovoltaic (PV) systems because those are usually set up at the place where few tall structure around it. Therefore, it becomes important to establish lightning protection methods. When a lightning occurred near a PV system, the PV modules have the induction overvoltage due to the lightning. As a result, the power conditioner connected to

No doubt that there are standards govern the lightning protection system installation for building and the solar PV itself which can be obtained from the International Electrotechnical Committee (IEC) and various other national and international standards, respectively.
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) .
With all the barriers discussed in Section 3.3, the need for lightning protection on PV systems must be evaluated on the basis of the risk analysis and protection costs. Table 10 presents the recommended standards related to PV systems including PV installations, lightning protection systems and electrical installations. Table 10.
The lightning protection of photovoltaic installations is of great importance, in order to warrant the uninterrupted operation of the system and avoid faults and damages of the equipment. Atmospheric discharges influence the proper operation of the photovoltaic generators and their installation, involving also sensitive electronic equipment.
The problem becomes more serious for the industry, as the number of photovoltaic power plants increases. These common practices aim to present the practical techniques commonly used by project managers and installers to set up lightning protection.
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. An inductive coupling model for PV panels was also proposed to assist the design.
