Solar Water Pump

The solar water pumping system uses solar energy to pump water.

Parts of a solar water pumping system:

• Solar PV panel

• One of the following motor-pump sets compatible with the photovoltaic array:

  • surface mounted centrifugal pump set
  • submersible pump set
  • floating pump set
  • Submersible pump set

• Pipes

Working of a solar water pumping system

The system operates on power generated using solar PV (photovoltaic) system. The photovoltaic array converts the solar energy into electricity, which is used for running the motor pump set. The pumping system draws water from the open well, bore well, stream, pond, canal etc. The system requires a shadow-free area for installation of the Solar panel.


A system with 1800 watt PV array capacity and 2 HP pump can give a water discharge of 1.4 lakh litres per day from a depth of 6 to 7 meters. This quantity of water is considered adequate for irrigating about 5-8 acres of land holding for several crops.

Advantages of a solar water pumping system

  • • No fuel cost - as it uses available free sun light
  • • No electricity required
  • • Long operating life
  • • Highly reliable and durable
  • • Easy to operate and maintain
  • • Eco-friendly
