The increasing demand for energy, coupled with the urgent need to mitigate environmental impacts, has driven the exploration of renewable energy sources, particularly solar energy, in building applications. This study investigates the potential of integrating photovoltaic (PV) systems into buildings in Saudi Arabia, The Case Study of Photovoltaic Systems is at Taibah University, Medina, Saudi Arabia. The research aims to evaluate the efficiency of solar energy technologies in reducing energy consumption and achieving sustainable building practices. Using Helioscope simulation software, the study examines the performance of PV systems under various tilt angles (0° to 75°) and assesses the impact of shading, system efficiency, and annual energy output. The results indicate that optimal tilt angles significantly influence energy generation, with a 30° tilt angle yielding the highest performance ratio and energy output. The study also highlights the potential of building-integrated photovoltaic (BIPV) systems to contribute to zero-energy buildings in the region. Furthermore, The research presents designing rotating solar panels by tracking the sun and using Arduino microcontrollers to achieve perpendicular alignment with the sun for higher solar panel efficiency. The findings suggest that solar energy, particularly in sun-rich regions like Saudi Arabia, can play a vital role in reducing reliance on non-renewable energy sources and mitigating environmental pollution. This study provides valuable insights for policymakers, architects, and engineers aiming to promote sustainable energy practices in building design and construction
