SOLAR PUMP

 

A solar-powered pump is a system running  on  electricity  generated  by  photovoltaic  panels as Opposed to  grid electricity. The operation of solar powered pumps is more economical mainly due to  the  lower  operation  and  maintenance costs  and has less  environmental impact  than pumps powered by an internal combustion engine (ICE). Solar pumps are useful where grid electricity  is unavailable and alternative sources (in particular wind) do not provide sufficient energy.

A solar water pumping system mainly consists of array, water pump inverter and DC pump, easy for use. Solar powered water pumps can deliver drinking water  as well  as  water for livestock or irrigation purposes.

 

A solar photovoltaic (SPV) water pumping system consists of;

PV array :

  • Should be mounted on a suitable structure with a provision of tracking the sun
Motor Pump Set (Surface or submersible) :
  • D.C. Motor Pump Set (with Brushes or Brush less D.C.)

                OR

  • A.C. Induction Motor Pump Set with a suitable Inverter

Electronics :

  • Maximum Power Point Tracker (MPPT)
  • Controls / Protections.

Interconnect Cables and “On

  • Off” switch.
