<p><P>PROBLEM TO BE SOLVED: To obtain a watering system for a solar cell power generation panel, capable of improving power generation efficiency by watering using a reduced amount of water and excellent in power generation efficiency. <P>SOLUTION: A watering system for a solar cell power generation panel includes: a solar cell power generation panel that has a light-receiving surface inclined to the horizontal plane and is installed with an interval between an installation surface and the solar cell power generation panel; a watering section that is arranged at an upper end of the solar cell power generation panel or above the upper end, and can perform watering by jetting water on the light-receiving surface of the solar cell power generation panel and the installation surface on a rear surface side of the solar cell power generation panel; a water supply section supplying water to the watering section; and a pressure change section that can change a pressure of the water jetting in the watering section in a plurality of stages. By changing the pressure of the water jetting in the watering section, a drop position of the water jetting from the watering section is controlled so that a watering region can be selectively changed. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
