| Abstract
This study presents the design, simulation, and performance evaluation of a 150 kW rooftop grid-connected photovoltaic (PV) system installed on the Atlas Commercial Complex in Tabriz, Iran. Utilizing PV*Sol Premium software, a comprehensive 3D model of the building was developed to optimize panel layout, tilt angles, and row spacing based on local climatic and solar radiation data. The system comprises 227 high-efficiency LONGi modules, supported by SMA inverters, distributed across multiple roof orientations. Simulation results indicate an annual electricity generation of approximately 287,000 kWh with a specific yield of 1903.43 kWh/kWp and a performance ratio (PR) of 85%. Shading losses were limited to only 4.6%, demonstrating the effectiveness of the system’s spatial configuration. The PV installation is capable of meeting 23–26% of the building’s annual electricity demand, significantly reducing grid dependency. Furthermore, the system prevents over 135,000 kg of CO₂ emissions annually, highlighting its environmental contribution. This study underscores the technical and ecological viability of integrating rooftop PV systems in commercial buildings, especially in urban regions with high solar potential. It also emphasizes the importance of simulation-based design and site-specific optimization for maximizing energy yield and sustainability outcomes.
