The primary challenge in designing and executing purification plants is energy; this worry is magnified in isolated places with little or no connection to the primary power grid. This research evaluates a reverse osmosis filtration plant's off-grid hybrid alternative energy source. The facility, which has a purification capacity of 10 m3, is located in the Malang district in Indonesia's western region. The site's climatic characteristics, such as air temperature, wind speed, solar irradiance, and clearness index, are obtained for better evaluation. The simulation was carried out using Homer software, and all potential PV/wind turbine/generator/battery combinations were computed and contrasted. Finally, the results of two different strategies, a fully renewable hybrid energy system with and without a backup generator, are shown. Experiments have shown an off-grid hybrid energy source consisting of a 12.5 kW PV panel with a power output of 335 W and an array of batteries totaling 205 Ah. A backup generator is the most cost-effective option. It costs $0.37 to produce one unit of energy; however, the cost of each unit of energy produced by an integrated PV/wind turbine/battery system is $0.275. © 2023 Regional Energy Resources Information Center (RERIC), Asian Institute of Technology.
