Installing a PV system on the roof of a building introduces new fire risks to the building or damages to the system. First, the PV installations have been shown to increase the chances for. NFPA 1 provides guidance on how solar photovoltaic panels must be installed on the roofs of homes.. Design flaws, component defects, and faulty installation generally cause solar rooftop fires. As with all electrical systems, these problems can cause arcs between conductors or to the ground, as well as hot spots, which can ignite nearby flammable material.. This data sheet provides property loss prevention guidance related to fire and natural hazards for the design, installation, and maintenance of all roof-mounted photovoltaic (PV) solar panels used to generate electrical power.. Both the National Electrical Code (NEC) and International Building Code (IBC) require PV panel installations to be listed per UL 1703. Prior to 2013, PV panels/modules were tested without an underlying roof cover, but are now required to undergo five fire tests, four of which place the ignition source between the roof cover and the panels/module.
