This paper explores the performance evaluation and optimization strategies of photovoltaic (PV) systems in urban environments. It highlights the unique challenges posed by urban landscapes, such as limited space, shading effects, and varying solar exposure. The study examines the key factors influencing PV system performance, including building layout, solar radiation, shading, and module materials. It also discusses various performance evaluation methods, including energy output calculation, economic analysis, reliability assessment, and environmental impact evaluation. Furthermore, the paper explores optimization strategies, focusing on advanced PV technologies, optimal installation practices, and the integration of smart control systems and energy storage. Future trends in emerging technologies, urban planning, and multi-energy integration are also examined, with an emphasis on their role in shaping the future of urban photovoltaic systems. The research provides valuable insights for improving the efficiency, reliability, and sustainability of solar energy systems in cities.
