The solar pump system is mainly composed of solar panel, solar pump inverter, water pump, PV combiner boxe, mounting bracket, cables , water level sensor and other necessary accessories. The photovoltaic generation technology is used to solve the problem of power supply and water supply on the spot. The initial investment cost is less than 2KM and the long-distance erection grid. The comprehensive cost is lower than diesel generator after two years of continuous working. It is widely used in photovoltaic agricultural irrigation, irrigation station reconstruction,household water supply and desert greening,where there is no electricity or insufficient electricity supply.The photovoltaic array is made up of many solar panels connected in series and in parallel, and the solar energy is convert...
