Abstract

Solar energy use for groundwater abstraction is one of the most viable options for smallholders’ irrigation in the current scenario of increasing fuel prices. Therefore, the dissemination and adoption of solar pumps of low capacities among these farmers is in demand. In this paper, a case study was in the eastern region to assess the performance of 3horsepower solar pump, as this capacity pump is currently being promoted by the governments to small farmers at subsidised rates. In the eastern region where groundwater regime in most of the area is ranging5-10 m bgl with annual fluctuation of ±2 to ±4 m, and abstracted groundwater by a 3 horsepower solar pump is range from 100-173 m3/day, depending upon the months on a bright day. This pump also offers a delivery pressure head 1.0- 1.5 kg/cm2 and therefore facilitates pressured irrigation for improved water use efficiency.
