Abstract
Building integrated photovoltaics (BIPV) typically operate under different conditions compared to standard PV due to non-optimal orientations, poor ventilation, or additional losses in coloured modules. In this work, a test site for BIPV curtain wall façades was constructed at the Technical University of Denmark (DTU) and monitored for a full year. This data is used to analyze various performance aspects, including operating temperatures, power optimizer efficiencies, and DC performance ratios. In addition, parts of the system are modelled in SAM and results of this simulation are used to identify errors. In addition to this analysis, the underlying data set is published for researchers to use in model validation.
