Contribution à l’étude du couplage énergétique enveloppe / système dans le cas de parois complexes photovoltaïques (PC - PV)

Abstract : This thesis presents a thermal and electrical modelling of PV walls integrated to buildings. The particularity of this model is that the heat transfer that occurs through the panel to the building is described so that both building and PV thermal modelling are fully coupled. This has the advantage of allowing the prediction of the impact of PV installation on the building temperature field and also the comfort inside it. The aim of this study is to show the impact of the PV panels in terms of level of insulation or solar protection for the building. Moreover, the study has been conducted in La Reunion Island, where the climate is tropical and humid, with a strong solar radiation. In such conditions, it is important to minimise the thermal load through the roof of the building. 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 production of electricity. Finally, the experimental study is used to give elements of validation for the numerical model and a sensitivity analysis has been run to put in evidence the governing parameters. It has been shown that the radiative properties of the PV panel have a great impact on the temperature field of the tested building and the determination of these parameters has to be taken with care. Results of sensitivity analysis are used to optimize the PV thermal model using the GenOpt optimization program.
