Due to their pollution of the environment and the damage they cause to human health, renewable energy sources have emerged as a promising solution amid ongoing efforts to find alternatives to fossil fuels and nuclear energy. There are hybrid energy system applications consisting of two or more renewable energy sources. In this study, a hybrid power plant design utilizing solar and diesel energy was developed for Aksu Village, consisting of 36 households in the Hasankeyf district of Batman province, with the help of the HOMER Pro Program. A hybrid system connected to the electricity grid was considered, with solar energy panels to be used when needed. It was determined that the settlement would consume 450,000 kWh of electricity per year in 2023, which is an average of 37,500 kWh per month and 1,250 kWh per day. When the cost analysis of the hybrid system was performed, the lowest-cost system required an initial capital of 8,378,332 TL ($288,908) and an annual operating and maintenance cost of 1,724,949 TL ($59,481). Based on the electricity data used for the system, the cost per kW was found to be 5,104 TL ($0.176).
