The main objective of this study is to investigate the technical and economic feasibility of using solar photovoltaic (PV) energy to reduce the net power drawn from the grid by submersible pumps in urban water supply systems. The Germiralti catchment area (Kayseri, Turkey), which provides all of its energy needs from the city electricity grid, was chosen as the research area. Two different scenarios, 'hybrid-powered water pumping system' and 'grid-connected PV system', were analyzed and evaluated. A 1,620 kWp grid-connected PV system can inject 2,787.8 MWh/year of energy into the grid, which is more than the total annual energy need of the submersible pumps. The system operates with 85.7% performance ratio (PR), 19.6% capacity factor (CF) and 4.71 (h/d) final yield. The payback period of the system is calculated as 4.1 years. The results show that it is economically competitive to meet the energy needs of submersible pumps in urban water supply systems with solar PV energy.eninfo:eu-repo/semantics/openAccessKayseriphotovoltaicPVsystsolar energysolar photovoltaic water pumping systemsurban water supplyArticle1352048206910.2166/wcc.2022.3772-s2.0-85131868363Q2WOS:000780100300001Q2
