Abstract

Solar energy has emerged as one of the most efficient and sustainable renewable sources for powering water pumping systems, particularly in rural and agricultural regions where conventional electricity grids are unavailable. Photovoltaic (PV) water pumping systems (WPS) provide an independent and cost-effective alternative that supports both energy and water security. In this study, a solar-powered water pumping system was designed and simulated using PVsyst software to drive an 11-horsepower submersible pump. The analysis investigated the influence of various PV panel technologies and thermal parameters, focusing mainly on the open-circuit voltage temperature coefficient (μVoc), on system efficiency and annual water yield. Simulation results demonstrated that PV panel technology and thermal behavior have a measurable impact on overall system performance, with lower (less negative) μVoc values leading to higher pumping efficiency and water output. The findings confirm that selecting panels with improved thermal characteristics significantly enhances system productivity and economic viability. This research contributes to optimizing PV-based pumping design for sustainable agricultural applications, promoting renewable energy adoption, and supporting the achievement of long-term water and energy sustainability goals.
