Solar energy water pump

A solar energy water pump comprises a solar energy cell panel and a water pump connected with the solar energy cell panel. A solar energy controller is arranged between the solar energy cell panel and the water pump, and further connected with an energy storage machine. The solar energy controller comprises a charge controller for connecting the solar energy cell panel with the energy storage machine and an electric discharge controller for connecting the energy storage machine with the water pump. The electric discharge controller comprises an electric discharge ending machine, an inverter and a frequency changer. The water pump comprises water leaves and a variable frequency motor for driving the water leaves. Therefore, the solar energy water pump has the advantages that consumption is low, endurance time is long, solar energy cell panel power is low, initial cost investment is low, structure is reasonable, installing is simple, waterproof effect of an electrical part is good, and service life is long.
