DESIGN AND DEVELOPMENT OF SOLAR POWERED SPRAYER

Abstract

This study explores the design and development of a solar-powered sprayer to address the inefficiencies and health risks of traditional pesticide application in Nigerian agriculture. Manual spraying methods are labor-intensive and expose operators to harmful pesticides, posing significant health hazards. To mitigate these issues, a solar-powered sprayer was developed, integrating solar energy systems with advanced spraying mechanisms for improved functionality, efficiency, and sustainability. The sprayer features durable materials, a robust chassis, solar panels, an electric motor, and a battery system, optimized for ergonomic use. It includes two 16-liter tanks, a spraying frame with adjustable height settings for diverse crops, and ten nozzles for even pesticide distribution. Performance tests demonstrate a field efficiency of 81.6%, covering 0.20908 hectares in 6.11 minutes, with theoretical and actual field capacities of 2.51 ha/h and 2.05 ha/h, respectively. This innovation offers a sustainable, cost-effective alternative for modernizing agriculture.
