Optimization of Solar Photovoltaic Water Pumping Systems Through Design Enhancement and Simulation Analysis

This research systematically investigated the optimization of solar photovoltaic water pumping systems through PVsyst-based simulation and design enhancement. Integrated optimization of the PV array, MPPT algorithm, motor-pump assembly, and hydraulic infrastructure achieved 13.9% overall system efficiency a 28.7% improvement over baseline and 26.9% greater annual water delivery. Motor-pump subsystem optimization emerged as the dominant performance driver, while integrated approaches proved approximately 5% superior to sequential component optimization. The findings provide actionable, evidence-based design guidelines for engineers, policymakers, and development organizations seeking to maximize the impact of SPWPS investments in off-grid agricultural communities.
