<P>PROBLEM TO BE SOLVED: To provide a solar water heater system accurately determining a failure of a temperature sensor of a solar heat collection panel by utilizing a solar power generation device installed in a solar water heater. <P>SOLUTION: In the system including the solar water heater 2 with the solar power generation device 1, a control part 10 of the solar water heater 2 is provided with a communication means for communicating with a control part 6 of the solar power generation device 1. The control part 10 of the solar water heater 2 determines whether the sun is shining or not by obtaining information whether a solar power generation panel 3 is generating electric power or not from the control part 6 of the solar power generation device 1 by using the communication means. When the control part 10 determines that the sun is shining, it determines that the sensor of the solar water heater 2 is faulty if the sensor does not show a detection value for sunshine. <P>COPYRIGHT: (C)2012,JPO&INPIT |
