20.500.12556/DiRROS-21483 Experimental study of fire propagation on sloped roof with building applied photovoltaics Photovoltaic modules have been shown to influence how a fire propagates across a flat roof, but the circumstances for which building attached photovoltaic (BAPV) modules promote fire propagation on a sloped roof is not studied in detail. Therefore, a series of small-medium- and large-scale experiments on a sloped roof with a BROOF(t2)-rated bituminous roof membrane on a wood chipboard substrate has been performed. Steel plates mimicking non-combustible photovoltaic (PV) modules were placed at different distances above the roof. Different sized wood cribs placed in the gap between the roof and the PV module were used as the ignition source. Similarly to findings for flat roofs, the experiments showed that the gap distance and the size of the ignition source are key factors for how far the fire propagates from the starting point. This supports that BAPV installations affect the fire dynamics on roofs. As such, the complete system of roof composition and PV installation needs to be considered as a whole to ensure adequate fire safety levels. photovoltaic systems fire propagation roof safety ignition source heat flux fotovoltaični sistemi širjenje požara varnost strehe vir vžiga toplotni tok true false true Institute of Physics Publishing Angleški jezik Slovenski jezik © authors, 2024 Neznano 2025-02-12 09:00:00 2025-02-12 09:11:26 2025-02-13 03:38:56 0000-00-00 00:00:00 2024 0 0 Nasl. z nasl. zaslona; Opis vira z dne 22. 1. 2025; Št. prispevka: 012047; Str. 1-6 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2024-11-01 624 1742-6596 10.1088/1742-6596/2885/1/012047 223533315 219018755 https://iopscience.iop.org/article/10.1088/1742-6596/2885/1/012047 1 5df58fbf-e917-11ef-9f1e-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=30673 RAZ_Stolen_Reidar_2024.pdf RAZ_Stolen_Reidar_2024.pdf 1 5C41D5429990D812A77BE80456C66EE9 e06488c1718ea4bb3b56d6853d406d1dad290a2f9c6b695f0e2f66889b33f4bc ef79b8bb-e918-11ef-9f1e-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=30675 Zavod za gradbeništvo Slovenije 0 0 0
