The use of photovoltaic (PV) module for push type solar operated sprayer is one of the most promising techniques in solar energy application. The push type solar operated sprayer consists of a PV module of 20W and two diaphragm type pumps of 0.03hp each. The system was tested for its performance in terms of variation is in nozzle discharge for different operating pressure and height. It was observed during normal climatic condition the PV module produced power in the range of 7.1W to 17.29W from 10:00am to 4:00pm in the month of December 2015.It was also observed that the nozzle discharge initially was found to be less during morning 10:00am later on gradually increased up to 12 noon and again found to be decreasing till evening 4:00 pm due to low solar intensity. We also observed that the discharge obtained from two types of hollow cone nozzles which are two slits and four slits for different operating pressure of 2, 3and 4 kg/cm2 at different spray height 49, 51and 53 cm respectively, but the required discharge rate was obtained from two slit hollow cone nozzle at an operating pressure of 2 kg/cm2 rather than four slits hollow cone nozzle. The actual and theoretical field capacity of push type solar sprayer were 0.29 ha/h and 0.32 ha/h for field bean crop with forward speed of 0.53m/s respectively. It was observed that, the cost of operation of solar operated push type low clearance sprayer was found to be Rs.38.5/h. The push type solar sprayer is working efficiently in row crops and vegetable crops by adjusting swath width as well as height of boom depending upon requirement.
