The integration of photovoltaic systems with rainwater harvesting offers a promising solution for enhancing water and energymanagement in arid and semiarid agricultural regions."This study presents an agrivoltaic system where photovoltaic panelsfunction both as energy source and as surfaces for runoff collection, directing rainwater into a storage reservoir for irriga-tion. A detailed analysis was conducted to evaluate different scenarios, for a period of ten years, including panel inclination,optimizing at 35°, and the expansion of the photovoltaic field, to enhance energy efficiency and water availability. The resultsdemonstrate that this approach significantly reduces water shortages, reducing critical cases below 50% in first scenario,particularly during peak irrigation demand periods, while increasing the system’s storage capacity and overall resilience toclimate variability. The expansion of the photovoltaic system, which is scalable according to the application, demonstratesthe overall reduction of critical cases in irrigation availability, increasing the reservoir capacity up to 60,000 m3, which canbe combined with increased management of energy generated for the grid, or local generation in remote areas, in combinationwith improved water supply management. Additionally, the system improves energy sustainability by reducing reliance onexternal sources and lowering carbon emissions from agricultural activities. The findings highlight the potential of integratingphotovoltaic systems into irrigation management as a scalable and replicable framework for enhancing resource efficiencyand sustainability in water-scarce regions
