Abstract

Recently, concerns over light pollution caused by solar reflections from building exterior materials and photovoltaic (PV) modules have been increasing. Additionally, with the expansion of renewable energy installations to meet carbon neutrality goals, the use of Building-Integrated Photovoltaic (BIPV) systems has increased. Consequently, concerns about glare problems caused by BIPV systems have grown. Some countries have implemented regulations to prevent glare damage by limiting the reflectance of building exterior materials. However, BIPV modules are designed with technologies that minimize surface reflectivity to enhance power generation performance. Nevertheless, BIPV use large-scale installation on building facades, which can lead to prolonged glare events. Therefore, simple reflectance regulations are insufficient as glare mitigation strategies; methods to quantitatively evaluate glare phenomena—including their occurrence, duration, and intensity—are needed. Various studies have been conducted to evaluate the glare of BIPV modules, mostly focusing on specific environments such as airports or large-scale solar power plants, and mainly through simulations. However, there is a lack of research on glare evaluation methods for BIPV modules installed in residential and commercial buildings. Especially, differences in glare occurrence criteria, measurement factors, and evaluation ranges make it difficult to quantitatively compare and analyze research results. Therefore this study analyzes the trends in research on glare evaluation methods for BIPV modules and related regulations in different countries. Based on this analysis, we propose a glare evaluation method for BIPV modules, measurement factors and evaluation ranges.
