Flammability Performance of Roof-Mounted Photovoltaic Products and Updates to UL 1703
Dwayne Sloan, UL Chris Flueckiger, UL

There have been significant changes for the fire classification approach for roof-mounted, stand-off photovoltaic (PV) modules and panels evaluated in accordance with UL 1703, Flat-Plate Photovoltaic Modules and Panels. With recent changes to UL 1703, the fire classification approach takes into account the module or panel in combination with the mounting system and the roof covering products over which it is installed. The proposals that led to these changes were an outgrowth of research tests conducted, and broad stakeholder forums held through a partnership between UL and the Solar ABCs. This session will summarize the research work, provide a look into Code changes and regulations on rack-mounted PVs, and provide an overview of the new UL 1703 fire testing and classification scheme. It will also provide an update on current UL 1703 Standards activities, and efforts involving industry-wide solutions, and rack mounted PVs used over non-combustible roofs.
