Solar Water Pumps

Photovoltaic pumping system commonly known as solar water pumps has been increasingly recognized as the most attractive means of water supply in the sun-rich areas of world, especially in the remote areas where there will be poor grid supply or no grid connectivity.

Solar water pumps provide the perfect sustainable, reliable and cost efficient alternative to irregular water supply solutions in remote locations, or for highly specific applications anywhere. Theses pumps provide individual solutions to water problems where conventional water supply systems fail or simply cannot reach. In this type of systems, the power generated by solar pv modules is used for operating a submersible pump for lifting water from bore / open well or water reservoir to storage tanks.
