Working Principle of Solar Water Pump
A solar pump works on the base of the photovoltaic principle. During the working of a solar pump, PV (photovoltaic) systems absorb radiant solar energy and transform it into electricity. This produced electricity supplies to the entire system.
The inverter of the pump converts the direct current output of the PV system into alternating current, which drives the pump. These inverters also adjust the output frequency and voltage in real-time, corresponding to variations in the sunlight intensity to attains the highest power point tracking.
As the intensity of the sunlight becomes weaker, the water lifting system realizes the function of switching the municipal power that works as auxiliary energy for the water lifting system.
