TThe Seoul Metropolitan Government announced a comprehensive plan for “Solar City, Seoul,” which is aimed at 1GW of power for 1 million households by 2022. Subsidies for the installation of BIPV(Building Integrated Photovoltaic Systems) in private buildings were expanded in 2020. It is therefore necessary to consider the building-integrated photovoltaic performance to harmonize with urban landscapes using renewable energy sources to realize zero-energy buildings. A field experiment was conducted to investigate the conditions of the BIPV, and the performance impact factors were analyzed. The results showed that the general glass, BIPV intermediate space, and internal surface of the BIPV temperature increased when insulation was added to the BIPV back panel in the spandrel part. The temperature increase in the Spandrel part is mainly caused by solar radiation, and the intermediate space temperature of the general glass rises higher than that of the BIPV module installation. The performance of the BIPV system was evaluated through a simulation. The simulation results showed that the temperature of the solar cell during BIPV generation depended on the energy balance of the effective solar radiation and ambient temperature. In the future, a comprehensive review of the module and material performances, such as the power generation and efficiency, will be required based on experimental verification.
