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
- DA.C. Induction Motor Pump Set with a suitable Inverter
Electronics :
- DMaximum Power Point Tracker (MPPT)
- D>Controls / Protections.
Interconnect Cables and “On
- Off” switch.
