System description

  • The agricultural land is situated in a remote location, away from national grid supply. The system totally operates off the grid and powered by a PV array of 23.1 kWp

  • Agricultural land of 1600 Acres was fully covered using the installed system. Overhead tanks, Sprinklers, Dip irrigation systems etc. were operated using pump.

Design Considerations

  • The installed pump was converted to a solar powered system using a VFD operated using Solar energy, without replacing the existing pump.

  • The PV array was sized in order to match the normal operating conditions and run the pump in rated RPM. 3 string having 14 Nos of 550W panels each were mounted on ground and rooftop both.

Advantages of the system

  • Very economical rather than using fossil fuels or electricity for agricultural water pumping purposes. The overall operating cost of the system is minimal.

  • Solar pumping systems are ideal for remote locations where electricity is not available. They can provide a reliable source of water for remote communities, livestock, and agriculture.
