PROBLEM TO BE SOLVED: To provide a solar battery panel cooling system that neither consumes circulation water nor needs a special cooling device such as a cooling tower, an air-cooling radiator or the like.SOLUTION: A solar battery panel cooling system includes a cooling unit 20 which is provided on the back surface of a solar battery panel 10 and forms a flow path of circulation liquid on the back surface, and circulation paths (30, 32) having a cold heat storage unit for circulating the circulation liquid. By circulating the circulation liquid in the circulation path, heat of the solar battery panel in the daytime is stored in the cold heat storage unit (water storage tank 40) to cool the solar battery panel, and the cold heat storage unit warmed by heat of the solar battery panel 10 at night. Therefore, the circulation liquid is circulated on the back surface of the solar battery panel 10, and the circulation liquid is cooled by the temperature difference from the outdoor air in the solar battery panel 10 and a radiation cooling action, thereby cooling the cold heat storage unit.SELECTED DRAWING: Figure 1 |
