摘要

Building integrated photovoltaics (BIPV) are becoming the new generation of building materials to tackle the rise of energy demand as global population grows. Under irradiance, solar panels generate heat due to incomplete conversion of solar energy to electricity. Accurate BIPV thermal modelling is crucial in designing energy efficient and low maintenance cost buildings. This research project models a replica of a full-scale experimental structure located in Dubai, UAE through computational fluid dynamics (CFD). The model includes c-SI and CIGS solar panels covering the west, south and east façades of the structure, and Dubai’s weather data. This validation seeks to achieve accurate representation of BIPV cladding and observe its thermal performance. The results are in agreement in one case deviating by only 0.03% and 3.17%, however the presented cases require greater refinement through a transient simulation.
