This paper deals with the integrated thermal modelling of photovoltaic panels for the solar protection of buildings under strong solar radiation as encountered in tropical and humid conditions. The thermal model is integrated in a building simulation code and is able to predict the thermal impact of PV panels installed on buildings in several configurations and also their electric production. Basically, the PV panel is considered as a complex wall within which coupled heat transfer occur. Conduction, convection and radiation heat transfer equations are solved to simulate the global thermal behaviour of the building envelope including the PV panels. The model is first detailed, with a focus on the radiation modelling within the semi-transparent layers of the panels and then preliminary results are presented in terms of verification. Conclusions are finally drawn regarding the impact of the panels in terms of thermal insulation for summer tropical conditions.
