Solar photovoltaic water pumping system: A software tool development-based optimal configuration investigation for system installation location, sizing and deployment

Water resources are essential for human survival, environmental stability, sustainable development, and economic growth. However, the lack of access to clean water poses a significant challenge to people's well-being. Solar photovoltaic-powered water pumping systems offer a sustainable solution to this prob-lem. Despite their implementation in various locations, there is currently no established methodology for optimal site selection and sizing. To address this gap, this study thoroughly investigates and analyzes the design and deployment steps of a solar PV water pumping system, including site selection and sizing of the components. A graphical user interface is developed based on fundamental equations to assist users in appropriately sizing the system for the most suitable site, aiming to minimize costs. The tool is rigor-ously tested and validated through a case study focusing on economically disadvantaged communities in remote areas with complex terrains. The results align with ground data, providing valuable insights into system design and deployment. This study serves as a comprehensive guide for designing solar PV water pumping systems, applicable worldwide with relevant data inputs. It contributes to the planning and implementation of sustainable solutions, addressing water access challenges through a scientific approach.& COPY; 2023 Elsevier Ltd. All rights reserved.
