The solar water pumping system is a stand-alone system operating on power generated using solar PV (photovoltaic)system. The power generated by solar cells is used for operating DC surface centrifugal mono-block pumpset for lifting water from bore / open well or water reservoir for irrigation and drinking water purpose.
Advantages of solar pump sets.
•No fuel cost-uses abundantly available free sun light
•No conventional grid electricity required
•Long operating life
•Highly reliable and durable- free performance
•Easy to operate and maintain
•Saving of conventional diesel fuel
Solar technology is very well suited to pumping water, even more so than the traditional windmill. A typical system includes one or more solar panels, an efficient 12 volt DC pump, a controller (with float switches), and a "linear current booster"
As long as it's daytime and the float switches show that the water source is not empty and the cistern in the house is not overflowing, the pump will run. The linear current booster allows the pump to run even if it's cloudy out.
Linear Current Booster (LCB)--This device trades voltage for extra current to start a pump. Electric pumps take more power to start up than they take to run, and the LCB takes care of this problem. It will allow your pump to start and run even on cloudy days.
Dear Mr Vijay Gupta
Engineers India Research Institute[.
Read your article with interest.I wonder with 12 Volts DC what RPM and Horse Power is possible. Most of the Bore wells use submersible Pumps rated 5 and above HP , lowered into the Bore wells beyond 300 feet into the ground.It is also possible to use invertor to convert DC to AC , using variable speed Motors for lifting water from deep Bore wells
Please update us to all readers what is maximum Pump rating possible with solar Systems. Who are the manufacturers in India. thank you
