Simulating building integrated photovoltaic facades: Comparison to experimental data and evaluation of modelling complexity

Building integrated photovoltaic (BIPV) systems provide an opportunity for renewable energy generation in the built environment. In order to quantify BIPV potential, numerical models of varying levels complexity have been developed. This paper investigates how affects their predictions. The study starts with a detailed multi-physics model that combines high-resolution one-diode physics-based thermal and airflow models. Next, simplifications are introduced into model. predictions compared experimental data from curtain wall installed test building Leuven, Belgium. results show is capable estimating daily yield average difference 6.2 % (2.0 clear sky days) back-of-module temperature 1.74 °C. use linear power instead differences, but not significantly: 8.7 (4.5 1.71 °C two different empirical correlations approach increases 3.5 4.4 10.2 10.4 %, respectively (5.9 5.5 days). These findings indicate version provides best agreement data, it still possible reduce acceptable accuracy.
