The current market of the photovoltaic (PV) industry is dominated by silicon-based modules, which are malfunctioned and degraded in higher temperatures mainly above 25°C. Consequently, one of the challenges for such modules is finding a more efficient way in their integration into the buildings in order to reduce the mentioned temperature. The present work is a part of a comprehensive framework toward the investigation of the lifetime durability of the BIPV modules. Therefore, this paper explain the development and validation of a computational fluid dynamics (CFD) model to be later utilized to evaluate the temperature distribution of BIPV's surfaces under different arrangements and climate loadings. For this purpose, a high resolution 3D CFD model is firstly developed by generation of about 3 million cells. Then, the model is validated with a velocimetry experimental dataset from the same model tested in a wind tunnel experiment by [6]. Furthermore, the solar radiation is added into simulation to model the non-isothermal condition of the BIPV module. The non-isothermal case is further validated with a thermography observation conducted by [5] where a solar simulator is installed inside the tunnel. The simulation results show that the developed model can accurately simulate the impact of 3D flow over/underneath the PV modules.
