Therefore, to protect solar panels from direct lightning strikes, rod or catenary wire lightning rods, that provide the necessary protection zone, are used. The type of protection of photopanels is determined on the basis of economic considerations, since they are not the most expensive components of the system.
Grounding is a technique to connect a part of the system electrically to the earth by means of a conductive material and is the key technique in Solar Lightning Protection. Earth could be considered as a sea of infinite electricity. Any charge/current that is transmitted to the earth is safely absorbed by it.
The necessary parameters of the grounding device (the design, the length of the electrode) depend strongly on the soil resistivity. In addition to low resistance, the grounding device must also be durable to ensure the uninterrupted operation of the solar power plant throughout its life.
The protection of the PVS from lightning is carried out on the same principle as any other object. To begin with, it is necessary to determine to which class of lightning protection the object, on which the photomodules are installed, belongs.
The aluminum frame of the solar modules. All the wiring should be grounded. One way of grounding the wiring is by running all the wiring in a metallic conduit and then burying it underground. Another way, if you are running cable trays to run the cables, is by grounding the cable trays along their entire length.
Lightning arrestors and surge protectors are designed to protect electronic equipment by absorbing electrical surges. However, these devices are not a substitute for good grounding. They function only in conjunction with effective grounding. The grounding system is an important part of your wiring infrastructure.

Grounding a PV System
Minimal grounding is provided by a copper-plated ground rod, usually 8 ft. long, driven into the earth. This is a minimum procedure in an area where the ground is moist (electrically conductive). Where the ground may be dry, especially sandy, or where lightning may be particularly severe, more rods should be installed, at least 10 feet apart.
