The present invention relates to a washing device for a solar energy module comprising: a washing water providing unit to provide washing water for a distribution unit, connected to the distribution unit with a tube to provide washing water for an entire or part of a first solenoid valve at once or with a time difference which is operable to correspond to a plurality of nozzles to spray washing water for a solar energy module; a washing water distributing unit, connected to the distribution unit with a tube, having a second solenoid valve operable to provide washing water for the distribution unit from the washing water providing unit, and a third solenoid valve operable for washing water remaining inside the tube and the washing water providing unit to naturally be discharged; and a control unit to control an opening and closing of the first, second, and third solenoid valves for the washing water remaining in the tube, distribution unit and washing water distributing unit to naturally be discharged to the ground. In the present invention, the nozzles, distribution unit and washing water distributing unit are vertically arranged with a solar energy module as a standard. The present invention is capable of efficiently cleaning and cooling the surface of the solar energy module with a small amount of cooling water. Additionally, by naturally discharging cooling water provided through a distribution line, a freezing accident which may be caused by a frozen distribution line during the winter can be prevented in the present invention. |
