Description
A solar PV water pumping system – commonly known as a solar pump – draws power from solar cells / modules to operate a motor pump set. Solar power pumps use specially developed and energy efficient motor pump sets to achieve higher discharge which offsets the high initial cost. A solar PV water pumping system consists of a number of solar PV modules connected in series – parallel combinations to generate sufficient power to operate a motor pump.
The solar PV modules are mounted on a metal frame in a manner that the mounting frame can be turned / tilted to ensure that the modules keep facing the sun throughout the day. The system does not have any storage battery since power generated is used directly then and there. The SPV array converts the solar energy into electricity which is used for running the motor pump set. The pumping system can draw water from the open well / bore well or stream / pond or canal.
Advantages of Solar Pump System
- Low Operation costs since fuel is not needed and the system runs on sunlight.
- It can be installed at a site completely eliminating loss of energy in transmission.
- Need only minimum maintenance and no battery is required.
- No electricity required.
- Highly reliable and durable.
- Easy to operate and maintain.
- No dependency on erratic or expensive fuel chain supply.
- Low regular maintenance requirements since solar panels and inverters have no moving parts.
- No pollution or noise produced.
- Extended lifetime (good quality solar panels are warrantied for 25yrs, inverters typically 6-8 years).
