Solar pumping system mainly consists of PV modules, solar pumping controller/inverter and water pumps. Solar panels convert sunlight to electrical energy which is passed to the solar pump controller. The solar controller stabilizes the voltage and output power to drive the pump motor. Even on cloudy days, it can pump 10% water flow per day. Sensors are also connected to the controller to protect the pump from running dry as well as to automatically stop the pump working when the tank is full.

• H1: Vertical distance from the pump to the ground
• H2: Vertical distance from water tank to ground
• L: Horizontal distance from water pump to tank
• Total head = H1 + H2 + L × 10%

• Time: 5 hours (estimated working hours of solar water pump)
• Daily water consumption: daily water consumption of water pump (m³)
• Actual flow: daily water consumption/time (m³/h)

Please select the right pump below yourself, or provide us with the following information so we can select the right pump for you:

• Where will the pump be used?
• How much water discharge (liters or gallon or m³) required per day or per hour?
• Do you need a submersible pump or surface pump?
• If you want to pump the water from borehole (deep well), the depth of borehole?
• The pipe distance from the top of borehole or river to destination tank? Is the distance slope or horizontal?
• The height of tank?
