Solar powered water pumps can deliver drinking water as well as
water for livestock or irrigation purposes. Solar water pumps may
be especially useful in small scale or community based irrigation,
as large scale irrigation requires large volumes of water that in
turn require a large solar PV array. As the water may only be
required during some parts of the year, a large PV array would
provide excess energy that is not necessarily required, thus making
the system inefficient.
Solar PV water pumping systems are used for irrigation and drinking
water in India . The majority of the pumps are fitted with a 2000
watt - 3,700 watt motor that receives energy from a 4,800 Wp PV
array. The 5hp systems can deliver about 124,000 liters of
water/day from a total of 50 meters setoff head and 70 meters
dynamic head.
