When you add a solar cell to the water tower / turbine / pump scheme, what you essentially have is a solar power system employing a water tower as an energy storage device. Such a system could store collected solar energy by pumping water up into the tower, and when the sun isn''t shining, the system can still produce power from the turbine.
Aside from the U.S., Spain has several power tower systems. Planta Solar 10 and Planta Solar 20 are water/steam systems with capacities of 11 and 20 megawatts, respectively. Gemasolar, previously known as Solar Tres, produces nearly 20 megawatts of electricity and utilizes molten-salt thermal storage.

CSP is used to produce electricity (sometimes called solar thermoelectricity, usually generated through steam). Concentrated solar technology systems use mirrors or lenses with tracking systems to focus a large area of sunlight onto a small area. The concentrated light is then used as heat or as a heat source for a conventional power plant (solar thermoelectricity). The solar concentrators use…
