AB  - In this study, a grid-connected photovoltaic (PV) solar energy system was designed for Izmir, one of Türkiye's regions with high solar energy potential, using PVsyst simulation software. The design was based on local solar radiation data, estimated electricity consumption, and the selection of suitable PV modules and inverters. Izmir receives approximately 2,737 hours of sunshine annually, and the average global solar irradiance is 1,620 kWh/m² per year, making it highly suitable for solar energy applications.The proposed system targets residential or small commercial users with an annual energy demand of approximately 6,000 kWh. A 6.3 kWp grid-connected PV system was found to be sufficient to meet this demand. The system includes high-efficiency monocrystalline panels, a series of inverters with 97% efficiency, and protective components that comply with grid standards. Installation angles were optimized according to Izmir's geographical characteristics to maximize output power. The economic feasibility analysis estimates the total installation cost at $6,500-7,000. Return on investment (ROI) is expected within 4 to 6 years, depending on electricity tariffs and net metering policies. In addition to the economic benefits, the system also contributes to reducing carbon emissions and fossil fuel dependency.This study highlights Izmir's strong potential for solar energy generation through grid-connected systems, demonstrating that such installations offer both environmental and financial advantages and could serve as a practical reference source for future renewable energy projects in the region.
