Solar Water Pumping Systems


The solar water pumping system is a stand-alone system operating on power generated using solar PV (photovoltaic) system. The power generated by solar cells is used for operating DC surface centrifugal mono-block pump set for lifting water from bore / open well or water reservoir for minor irrigation and drinking water purpose. The system schematic is shown in the figure below. The system requires a shadow-free area for installation of the Solar Panel The system is provided with 1800 W solar PV panel (24 nos. X 75 W) and 2 HP centrifugal DC mono-block / AC submersible with inverter. The average water delivery of 2 HP solar pumps will be around 1.38 to 1.40 lakh liter per day, for a suction head of 6 meters and dynamic head of 10 meters. The size of suction & delivery lines is 2.5 inches (62.5 mm). .

Advantages of solar pump sets :

  • No fuel cost-uses abundantly available free sun light.
  • No conventional grid electricity required.
  • Long operating life.
  • Highly reliable and durable- free performance.
  • Easy to operate and maintain.
  • Eco-friendly.
  • Saving of conventional diesel fuel.
