Fire Concerns with Roof-Mounted Solar Panels
There are three key considerations that affect fire spread along a roof where a roof-mounted PV array is installed: In a typical roof fire, the flame is primarily vertical, or perhaps somewhat slanted due to wind. Once such flames spread under a PV panel, the flame is redirected much closer to the roof surface and nearly parallel to it.
