20.500.12556/DiRROS-24443 PV-related rooftop fires – national statistics and the impact of reporting methods PV-related fires have caused significant property damage over the last decade, and their numbers are still rising, thus potentially undermining solar power's intended contributions towards sustainability. Robust solutions are needed to ensure risk reduction, and incident reporting is an important part of the risk analysis process. Statistics on the adverse events provide a good insight into the more prevalent failure modes and establish the failure frequency. An assessment of the data on PV-related fires shows that Italy can expect about 10 fires per GW annually, while Slovenia can expect about 37 fires per GW annually, compared to a previously established number for an international average of 29 fires per GW. Although the rates for both countries are in the same order of magnitude as the international average, the differences can be attributed to different methods of data collection, as well as to some differences in legislation and installation requirements in the two countries. Importantly, while acceptable risk levels are typically in the order of 10⁻⁶, the observed rates are in the order of 10⁻⁴, which is in a range that demands immediate risk management actions. fire safety photovoltaic systems statistics požarna varnost sončne elektrarne statistika true false true Institute of Physics Publishing Angleški jezik Slovenski jezik © authors, 2025 Neznano 2025-11-28 10:24:23 2025-11-28 10:32:39 2025-11-29 03:56:26 0000-00-00 00:00:00 2025 0 0 Str. 1-6 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2025-09-01 621.3 1742-6596 256632323 253630979 https://www.doi.org/10.1088/1742-6596/3121/1/012050 0 0d00b4aa-cc3c-11f0-94a7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=36401 RAZ_Rus_Nik_2025.pdf RAZ_Rus_Nik_2025.pdf 1 EB5DF5B5019D76E67B86ABEB537F9F55 38e5668f8e39f78c000cc2db922c195be59645e0d5c977cf8eafd4f8401bee9f 295393e1-cc3d-11f0-94a7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=36406 Zavod za gradbeništvo Slovenije 0 0 0
