PROBLEM TO BE SOLVED: To provide a solar battery device wherein driving parts for tracking the sun is reduced, and the occupation area of the solar battery is reduced while a hot water of a high temperature is obtained as required. SOLUTION: Rectangular solar battery cells 10 are provided, in parallel, with a constant interval, and over them, cooling water holes 12 for cooling the solar battery cells 10 are provided. Further, a hot water hole 14 is provided where no solar battery cell 10 is provided, and the hot water flowing the hot water hole 14 is heated to the high temperature under the sun light 40, which is used as a high temperature hot water. The front surface side of solar buttery cell 10 is directly irradiated with the sun light 40, while the light reflected on a mirror 42 comes to the rear surface side of the solar battery cell. In order that the light reflected on the mirror 42 always comes in the rear surface of the solar battery cell 10, a distance (I) between the mirror 42 and the solar battery cell 10 is changed according to the sun's movement. |
