Calculation of the Short-Circuit Current of Colored BIPV Modules under Field Conditions by Application of Spectrally and Angle Resolved Measurement Data

Description

The aim of this work is to determine the short-circuit current of colored solar glasses under field conditions, which includes varying solar spectral irradiance, oblique irradiation angles and fractions of diffuse light. Therefore, the field performance of colored building-integrated photovoltaic modules is calculated with spectral solar resource data and angular-dependent spectral responsivity measurements from laboratory testing. This method allows to examine the behavior of modules under test by application of physical laboratory measurements and spectral solar resource data. In order to validate the short-circuit current calculations, monitoring data from field tests are used. In order to assess the results, the short-circuit current is compared with a model using the incidence angle modifier. The results show that the application of angular-dependent spectral responsivity measurements allows to reduce relative mean bias error from 2.26% to 0.25% and relative root mean square error from 2.72% to 1.57% for the blue colored building-integrated photovoltaic module compared to the incidence angle modifier model, respectively.
