Under the policy frameworks and financing schemes for solar energy use in agriculture many Indian states are providing subsidies on small capacity solar pumps even upto 90% for the use of smallholders’ irrigation. One of most the popular and subsidised solar pump is of 3.0 HP solar submersible pumps, operated by 3.0kWp solar array. This paper presents the performance of 3.0 HP solar pump with tracking and fixed array evaluated under the prevailing solar global radiation of3.4-6.4 kWh/m2/day, solar irradiance of 0-930 W/m2 and the ground water depth regime 10 ±4m of Eastern region of India. The results showed that the 3 times manually tracked array yielded 19-23 percent more water compared to fixed array. The mean monthly daily groundwater yield with 3 times manually tracked array was found in range of 80-155 m3/day.
