Solar-Powered Drip Irrigation System

Abstract

The continuous increase in population and its demand for water and energy have caused great stress on the world’s water and energy resources. Consequently, it has become necessary to replace the conventional sources of energy with renewable energy and conventional methods of irrigation with high-efficiency irrigation systems to ensure global energy, food, and environmental security. In this context, a research-based study combining drip irrigation and photovoltaic system was conducted. A solar-powered drip irrigation system was designed, developed, and analyzed techno-economically for citrus, olive, and grapes. The performance evaluation has shown enormous results with water saving and fertilizer reduction of more than 50% and 40%, respectively, as compared to conventional irrigation system. Further, the system is found cost-effective over the years and requires minimal operational and maintenance cost. This paper may provide technical guidance for design and installation of solar-powered drip irrigation system.
