PROBLEM TO BE SOLVED: To solve such a problem of a conventional photovoltaic power generation system that since a sprinkling device for removing snow cover of a photovoltaic power generation module is not cryoprotective, the sprinkling path is destroyed and sprinkling cannot be carried out at a required timing.SOLUTION: The sprinkling device for use in a photovoltaic power generation system includes a sprinkling path for supplying water to a solar cell module from a water supply section for switching start and stop of sprinkling, and a sprinkling section for sprinkling water to the solar cell module. An aperture is formed at least in a part of the sprinkling path, and a drain handle capable of opening/closing the aperture freely is provided. Water in the sprinkling path after stopping the sprinkling can be drained by bringing the drain handle into open state from the aperture. |
