BENEFITS/ CONTRIBUTIONS
Solar water pumps are used for irrigation of crops, water livestock and
provide portable drinking water. Solar water pump uses peak solar array output
which frequently coincides with high water demand during long, dry summer days.
In the event of cloudy weather solar water pump systems often use storage tanks
to store excess water. Solar water pumps do not require fuel or constant
maintenance. Solar water pumps can also be designed for portability to be moved
as water demand or change of season requires. Their operating cost is less
compared to diesel pumps. Recent fuel price increases and generally intensive
maintenance schedules however can make diesel pumps expensive. Advantage of this Solar penal, it also comes with
two light sensors (LDR) which LDR is working to identify the
position angle of the sun,
allowing the photovoltaic technology is
in the right angle facing the sun. The SPV sets are highly economical when combined
with water conservation techniques such as drip irrigation & night time
distribution of (day time pumped & stored) water. The SPV system leads to
optimum exploitation of scarce ground water. The life cycle and the cost to
ultimate beneficiary
make the SPV systems cost effective as compared to conventional systems. IN
addition the farmer is saved from the capital investment he has to make for
drawing lines from the grid to his field/farms.
