Solar energy applications in agriculture: Design, implementation, and performance of a solar-powered irrigation system

The increasing demand for sustainable energy solutions in agriculture has intensified interest in solar photovoltaic (PV) systems, particularly for irrigation and rural electrification. Agriculture in developing countries faces persistent challenges such as unreliable grid supply, high diesel costs, and environmental degradation. This study presents the design, working principle, and practical implementation of a solar-powered agricultural system, with emphasis on solar water pumping, battery charging, and auxiliary loads such as water level indicators and lighting. The proposed system integrates photovoltaic panels, charge controllers, energy storage, and DC motors to deliver an efficient and environmentally friendly solution for irrigation. Performance analysis indicates that solar-powered irrigation systems significantly reduce dependency on fossil fuels, operating costs, and carbon emissions while ensuring reliable water supply. The study highlights technical feasibility, economic viability, and environmental benefits, making solar energy a promising alternative for sustainable agricultural development.
