Solar pumping system consists of solar pumping inverter, pump and PV array. Consider that storing water is more efficient than storing electricity; the system is designed to directly drive the pump without battery which can reduce the construction and operating cost and routine maintenance effectively. PV array consists of multiple solar panels connected in series/parallel, which can supply the whole system as power source by converting the absorbed solar radiation energy to the electrical energy.
Solar pumping inverter can implement the control of the whole system operation, which drives the pump by converting DC power produced by the PV array to AC power. This inverter can adjust the output frequency according to the solar irradiation intensity in real time to implement the MPPT (Maximum Power Point Tracking).The pump driven by a 3-phase AC motor draws water from deep-well or river. The pumped water is then fed into reservoir or water tank, or connected to the irrigation system or fountain system directly. All of centrifugal pump, mixed-flow pump, and deep-well pump can be utilized.
