Overview:
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.
Of all the ways solar electricity benefits the people on Earth, none makes as much
difference in the daily lives as pumping water. By providing water for irrigation or
potable water have obvious benefits for people in rural areas and especially for those
in developing nations. The proper choice is determined by application specific factors
like how much water is required and whether the water should be available at night
or just during high sun hours.
Solar Power and Irrigation:
 Irrigation is best utilisation of Solar power
 Usually area which require more water have high solar irradiation
 During summer time when more water is require, there is more sun light
 Water need not be available at night
 Maintenance facilities are lacking, Solar pump run maintenance free.
 Solar tracking can use.
