Wherever solar panels, tall buildings, towers, etc. are installed, it is necessary to install a lightning arrester. Because when lightning falls from the sky, first of all, it falls on the tall building. If we apply lightning conductors, it provides a conductive path.
It is a copper rod, the upper end of which is pointed or trident. It is placed at the top of the building. The other end of the metal rod is dug 6 - 8 meters deep in the moist soil and attaches to a copper plate or rod. When sky lightning falls, this rod creates a conductive path that absorbs the high voltage from the top to the ground, so that the component is safe.
At least two parts of the house should be equipped with lightning conductors. It has to be kept three feet high from the roof. Two copper wires should be tied in an iron rod in the ground below in an inch thick bar of iron placed in the device. Although the age of the device is 50 years, it should still be investigated. In homes where the solar panel is installed on the roof, if the sky falls on it, the total panel will be damaged or burned, so it is necessary to install a lightning arrester on it.
There is also a belief that celestial electricity only damages the house through the roof but it's not always. Whenever celestial lightning falls, its range is at least one to one and a half to two km. The celestial electricity enters the house through 'neutral'. To prevent this, it is now necessary to install surge arrestors. The lightning conductor is capable of stopping the celestial electricity from the roof, but when the electric neutrals make their way into the house, only Surge arrestor works for them.
