A Solar water pump system is essentially electrical pump system in which the electricity is provided by one or several photovoltaic (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.
Working of solar pump
Solar water pumps are specially designed to utilize DC electricity from solar panels. The pumps must work during low light conditions, when power is reduced, without stalling or overheating. Low volume pumps use positive displacement (volumetric ) mechanisms which seal water in cavities and force it upward.
