We can wax poetic all day long about the benefits of metal roofing products, but most clients boil all that information down to a single question: What about lightning? Isn't metal roofing dangerous? The short answer: No, it's not. read more
Of course, solar panels should be protected from lighting strikes. Solar systems are often installed in open spaces,far away from tall structures. In case of buildings, PV panels are installed at the roof. A direct lightning strike on solar panel can cause considerable damage to it. read more
Since a photovoltaic installation does not increase the probability of lightning strikes, the solar modules themselves are no more at risk than the inverter or other loads connected to the grid. However, in the rare event of the solar generator being hit by a direct lightning strike, the modules are likely to suffer considerable damage. read more
Requirements for lightning protection of solar panels can be found in NFPA780, the standard for the installation of lightning protection systems. The requirements in chapter 12 of NFPA780 refer back to the basic requirements for ordinary structures in chapter 4 and add specific requirements for solar panels. read more
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 even between clouds. But most lightning damage is preventable. read more
