Abstract

This article presents an analysis of the performance of a renewable system. Initially, relies solely on a solar panel system. Then, we add a wind turbine system to create a hybrid (solar and wind) system using Homer software. The results showed that the hybrid system and the stand-alone effectively meet the energy demands. Additionally, the results showed that the hybrid system was the most efficient way to store energy, which can be utilized when demand is high, thereby enhancing the independence and sustainability of the energy system. The simulation results showed that the site’s annual energy consumption was approximately 3230 kWh. In the solar-only case, the photovoltaic system generated 6099 kWh/year, of which about 53% directly met the demand, while the remaining 47% was stored in batteries for use during peak periods or outages. with the integration of a wind turbine to establish a hybrid system, the annual energy production rose to 9940 kWh. Approximately 32.5% of this energy was utilized directly, while the remaining 67.5% was stored in batteries. The hybrid configuration improved total energy generation by 63% and storage utilization by 20.5% maintaining system stability during winter and higher output under summer irradiance conditions.
