ABSTRACT: In this study, the optimal tilt angle of rooftop photovoltaic (PV) panels was investigated for a 5.3 kW grid-connected system located in Edirne, Turkey. The analyses were conducted using PV*SOL Premium 2024 software, evaluating different tilt angles ranging from 0° to 90°. Based on the simulation results, key performance indicators including annual energy yield, performance ratio (PR), CO₂ emission reduction, and payback period were assessed. The findings indicate that at a tilt angle of 30°, the system achieves an annual energy output of 7,763 kWh and a payback period of 4.2 years. This result aligns with the geographic and solar radiation characteristics of Edirne, suggesting that the optimal tilt angle is approximately 30°. Beyond 40°, both energy production and economic performance decline, with a significant drop in system efficiency observed at tilt angles of 70° and above. Furthermore, a strong linear relationship (R² ≈ 0.999) was found between energy production and CO₂ emission reduction, emphasizing the direct environmental benefits of increased PV output. In conclusion, a tilt angle of 30° represents the most efficient configuration for maximizing energy production and minimizing payback time under the climatic conditions of Edirne.
