Design and development of Solarised Agro Sprayer for rural applications

Agriculture is the backbone of India. In rural areas, spraying pesticides is done by hand spray. In rural areas, (petrol/kerosene) sprayers. These require manual operation/fossil fuel for its operation. To address these issues, a novel protocol is developed viz. Solar Agro Sprayer (SAP) is an innovative product developed for rural applications which utilizes the solar energy as a fuel. Proposed Solarised Agro Sprayer protocol is an innovative product especially developed for rural applications which utilizes the energy from the solar arrays is used for spraying the pesticides. The solar photovoltaic panel traps the solar arrays and this energy is stored in the Lead Acid battery. Battery powers the DC motor coupled fan and it´s used to extract the atmospheric air. Pesticide flows down due to gravitational force and a blower is attached to the DC Motor to boost the air pressure in spraying the pesticide. In nozzle both the pesticide and pressurised air mixes and pesticide is sprayed. The conventional sprayers cost ≤ 6,000, but the developed protocol cost is only ≤ 3,500. The main advantage of the developed protocol is it does not affect farmer health by any means and also it does not contribute to green house gas emission. This Proposed model proves an efficient and economic way of spraying pesticides and we also found that this method is more reliable.
