Abstracts: Most worlds are using conventional energy as the energy source to fulfil their general requirement. As the day passing the nonconventional energy is coming necessary to use because of rising economic rates of convectional energy. Solar energy is the most common nonconventional energy source. The solar energy is most easy source of energy can directly use to general requirements. Solar irrigation pump are this type of device which use solar energy for water pumping. Water pumping is an energy intensive activity and consumes a large amount diesel and electricity. Solar energy, which is abundantly available in India, can be used for pumping water via solar parabolic reflector. Smallholder farmers in low income countries can benefit from affordable irrigation pump systems as they enable cultivation of high value crops during dry season. This generates extra income and contributes to an improvement in quality of life. Currently the majority of small irrigation pumps are manually operated which is time consuming and requires a high level of physical exertion. There is a potential market for a low cost solar thermal pump that produces a high volume of water as well as reducing the labour burden. This will allow more crops to be grown and free up time for other productive tasks. Compared to the existing manual systems, many hours could be saved each day through reduced labour input. The device is powered by steam produced by a boiler that is heated by a parabolic dish solar collector. A steam engine acts as the prime mover converting thermal energy into mechanical power to drive a reciprocating positive displacement piston pump. When we will make system like this it will create attention of people at renewable energy and when it will come in wide use we will save the convectional energy in large amount.
