Abstract
The expansion of urban PV systems brings up the concern that the reflection from PV modules will cause glare to neighbors. In a densely constructed city, glare can occur when you have PV systems installed on the rooftops of low rises where the solar reflections travel to the surrounding high rises. This issue is more detrimental at airports, because glares from PV can blind the pilots or people working in the control tower which can lead to tragic accidents. The issue of PV glare can also affect trains and ships when they are sailing. A model based on Bidirectional Reflectance Distribution Function has been developed in this project to assess the occurrences of definite glare and potential glare areas (reflections) in the horizon of the given location throughout the year. The model has also been validated at the specific location in TU Delft by considering one of the PV system already installed in The Green Village.
