Solar water pumping systems are a modern but field proven means of pumping water in locations where access to grid power is not available, or where the grid is not reliable. These systems use photovoltaic (PV) cells to convert sunlight into electricity to power DC pumps which can be used to pump groundwater or surface water.Solar water pumps consist of a pump and a motor set, a solar power conditioning unit (SPCU), solar PV modules, piping, cables, foundation material and an earthing kit.The basic difference between solar water pumps and ordinary water pumps is that the motor of the former is run on solar generated electricity alone, while the later often runs on diesel. However, there is another key difference for a given pump head, solar water pumps give variable water output, depending on the intensity of ambient sunlight.They require no fuel deliveries, and very little maintenance. Solar water pumps are used worldwide for: Irrigation (lift and pressurized) Livestock (deep wells, pipeline transfer, pond and stream protection) Aquaculture (transfer, circulation, aeration, de-icing) Home and village supply Medical clinics Camp sites Water purification and treatment systems
