PROBLEM TO BE SOLVED: To provide a water sprinkling system for panel-type equipment, which improves cooling and snow-melting performance by circulation of the water in which water is provided by arranging a water circulation flow path for returning at least part of the water recovered after sprinkle over the panel-type equipment to a water-sprinkling pipe, to reuse the water for sprinkle.SOLUTION: Drive water is sent under pressure from an underground tank 10 to an ejector 5 through a drive water pipe 13 by a submerged pump 14. The water in a water collecting tub 6 is taken into the ejector 5 through an intake pipe part 4a of a water supply pipe 4 under pressure and mixed with the drive water. The mixed water is supplied from the ejector 5 to a sprinkling pipe 3 through a discharge pipe part 4b of the water supply pipe 4, and sprinkled over the surface 2A of a solar panel 2 from a plurality of injection nozzles 3A. The mixed water is then allowed to flow down there, collected in the water collecting tub 6, and resent to the sprinkling pipe 3 through the ejector 5 and the water supply pipe 4. Thus, the water circulation flow path 12 for water sprinkling is formed. |
