A reliable and clean water supply is an essential need but a large number of people currently lack this basic provision. Solar water pumps is a socially and environmentally attractive technology to supply water. Especially if the need for water is in remote locations which are beyond the reach of power lines, solar power is often the economically preferred technology.


Solar water pumps can supply water to locations which are beyond the reach of power lines. Commonly, such places relies on human or animal power or on diesel engines for their water supply. Solar water pumps can replace the current pump systems and result in both socio -economic benefits as well as climate related benefits. The water supplied by the solar water pump can be used to irrigate crops, water livestock or provide potable drinking water. 

A solar water pump system is essentially an electrical pump system in which the electricity is provided by one or several Photo Voltaic (PV) panels. A typical solar powered pumping system consists of a solar panel array that powers an electric motor, which in turn powers a bore or surface pump. The water is often pumped from the ground or stream into a storage tank that provides a gravity feed, so energy storage is not needed for these systems. A typical installation is illustrated in Figure.
