Alternatively, micro-hydro generators can be used with pumped water storage. With pumped water storage, excess energy produced by a photovoltaic system is used to pump water from a creek or dam to a higher level (for example, a water tank on top of a hill). To produce electricity, the water is fed from the tank through a micro-hydro turbine.
