PURPOSE:To effectively utilize excessive electric power with simple and cheap equipment by a method wherein water is pumped from a lower water storage container to an upper water storage container by using electric power generated by a solar battery and the water is dropped as the used arises to generate power. CONSTITUTION:An upper water storage container such as an elevated water storage tank 4 is installed on the roof or the like of a building while a lower water storage container such as ground water storage tank 4 of water supply 7 is installed. Then surplus of electric power generated by a solar battery panel 2 is used to drive a motor or the like to pump the water in the lower water storage container to the upper water storage container by a pumping means 11, Then as the need arises the water in the upper water storage container is dropped to the lower water storage container to generate electric power by a power generating means 11. In this ease a single mechanism serves both as the power generating means 11 and the pumping means, Thus, the surplus of electric power generated in the daytime is stored to be utilized effectively as the need arises. |
