The PV system and lightning protection system can be installed at the same time without any problems. If a photovoltaic system is subsequently placed on a roof area where a lightning protection system is already installed, there are several aspects that need to be considered. It is important to ensure the functionality of the external lightning ...
Lightning is a powerful, destructive force of nature and will strike a building regardless of its type of roofing. Metal roofs do not attract lightning strikes; nor do metal roofs protect a building against lightning. The only way to protect a building is with a properly designed and installed lightning protection system (LPS). Still, the type of roofing is one of several risk …
