Solar PV water pumps
The operation of solar powered pumps is more economical mainly due to the lower operation and maintenance costs and has less environmental impact than pumps powered by an internal combustion engine (ICE). Solar pumps are useful where grid electricity is unavailable and alternative sources (in particular wind) do not provide sufficient energy. Common uses of solar photovoltaic (PV) pumps are in potable water supply and livestock watering, particularly in arid and semi-arid areas which often have very high levels of insulation year round. The ability of solar PV pumps to work throughout the year can improve the resilience of the water sector to climate change.
