PROBLEM TO BE SOLVED: To solve a problem of an existing system in which a thermal detection sheet is attached on the entire surface of a solar panel, that is, to address the challenges of high cost and a heavy facility on a roof faced in a situation where the system has to use a thermal detection sheet nearly as large as the solar panel and the device has thus a large size.SOLUTION: By using a feature of a solar panel fire that fire-spreads the back of a solar cell module, a fire detection line is transversely arranged at the back of the obliquely set solar cell module and a fire can be thus detected. In that way, reduction in cost and reduction in weight in a case of setting on a roof can be achieved.SELECTED DRAWING: Figure 4 |
