Currently, fire tests for building integrated solar modules and fire tests for roof materials are managed separately. Thus, it is necessary to establish an appropriate test method for a building integrated photovoltaic (BIPV) system for the roof because the roof BIPV system has both of these characteristics, i.e., solar modules and building materials. In this research, two types of roof BIPV systems (with solar modules, without solar modules) were tested and analyzed for their fire performance, respectively. Fire tests were conducted based on KS F2257-1 and KS F2257-5. The results showed that the system with the module has weaker fire resistance performance than the system without it.
