Photovoltaic based electricity generation saves a major portion of renewable energy generation in India. Ever increasing fuel cost and doubtful availability of electricity hampers the irrigated crop production. Use of solar pump is an alternate to electric or diesel pumps for irrigation of crops. This paper presents the utilization of solar power for operating micro irrigation systems for irrigating field crops. An open well submersible pump of 5hp capacity was operated by 4960Wp solar panel installed at ICAR-CIAE, Bhopal for irrigation. The discharge rate of pump has been observed as 11400 to 24120 l/h at a dynamic head of 2.5 m corresponding to solar irradiation range of 164 to 808 W/m2 during time period from 8 am to 4 pm. The total power generation from the panel during this period has been observed as 3013.5 W. The total excess power availability during different irrigation treatments such as drip (T1), portable sprinkler (T2), rain hose (T3) and flood irrigation (T4) has been estimated for other uses of solar photovoltaic system. In different irrigation systems the excess power availability range per year per ha has been varies from 235 to 1160 kWh, 246 to 1213 kWh, 246 to 1213 kWh and 220 to 1084 kWh respectively. The maximum area irrigated by T1 of 2000 to 3500 m2 , T2 800 to 2500 m2 , T3 500 to 1500 m2 , T4 100 to 450 m2 . | Utilization of solar power for operating micro irrigation systems
