PV system onto a fire-rated roof changes the dynamics of fires that develop. If a fire develops on a roof with a PV system, the presence of the modules can keep the released en rgy closer to the roof and increase temperatures and heat fluxes to the roof. Thus, fires that could otherwise
hich is in line with findings by Kristensen and Jomaas (2018).KEY T EAWAYS:The fire risk with PV panels on roofs is larger than without panels.Assessing the fire safety of a PV installation must be done on the system level be ause individual elements do not necessarily present the risk comprehensively. However, the true risk emer
