A solar water pump

Is a system in which the electricity is provided by several Photo Voltaic (PV) panels. With the cost of diesel and electricity rising constantly, solar powered water pumps are the perfect alternative for rural regions as these have a low maintenance cost and ensure a long product life.

Solar Water Pump is the complete set of Solar panel, Voltage Frequency Drive (VFD), Panel Stand, DCDB, and Motor. 

Benefits and Limitation

  • Solar pump works during day time, hence freedom from working at night.
  • No fuel cost as it uses free sun light
  • No requirements of conventional electricity and diesel fuel.
  • No requirement of long transmission lines and no transmission losses
  • Easy to operate & maintain and long operation life
  • Highly reliable and environment friendly
  • Solar pump does not work in cloudy and foggy days
  • Water output varies with the variance of the sun shine
  • Solar panels require regular washing and cleaning as dust reduces the water output

Component of Solar Water Pump

  • Surface mounted centrifugal pump set
  • Submersible pump set
  • Floating pump set
  • Submersible pump set

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.
