Design and Developments in Different Types of Solar Modified Agricultural Spray Pump: A Review

Abstract

Abstract: Pesticide spraying is a major challenge in agriculture for protecting crops from insects. Farmers are currently spraying with hand-operated or fuel-operated knapsack sprayers. This paper addressed various solar sprayers made by various researchers to reduce the human effort when spraying in the field and as part of pollution-free and ecologically friendly green energy. In this article, some of the benefits and limitations of solar sprayers have been found and discussed, and future research needs in green technologies have been highlighted. This study attempts to provide a comprehensive solution to agriculture's future energy requirements. Spraying does not happen all year long. As a result, the same PV (Photo-Voltaic) system used in solar sprayers may be used to power other agricultural operations such as pumping and lighting. Increased pricing and nonavailability of traditional power or fuel at peak times in remote areas are two variables that influence their adoption. Farmers' accessible solar sprayers have low field coverage capacities, posing health risks due to direct consumption of spray drift and, as a result, contaminating the environment with engine-powered sprayers. As a result, the focus should be on designing and developing self-contained renewable energy sources that can provide consistent electricity and meet the energy needs of farmers who are far away from their farms.
