The Importance of Surge Protection Devices The capacity of a PV array is directly related to its exposed surface area, so the potential impact of lightning events increases with system size. In the area that lighting occurrences are frequent, unprotected PV systems could suffer repeated and significant damage to key components. It results in substantial […]
Background While small solar panels used for battery charging and similar tasks may not require special connectors, larger systems normally connect the panels together in series to form strings. In the past this was accomplished by opening a small electrical box on the back of the panel and connecting user-supplied wires to screw terminals within. […]
Overvoltage may occur in electrical installations for various reasons. It may be caused by: 1. The distribution network as a result of lightning or any work carried out. 2. Lightning strikes (nearby or on buildings and PV installations, or on lightning conductors). 3. Variations in the electrical field due to lightning. Like all outdoor structures, […]
