Résumé
This paper describes a model to account for the heat transfer and the convective flow induced in theinterior of a channel inclined 35° with respect to the horizontal, formed by a photovoltaic panel and an adiabaticplate. The model developed is validated experimentally by measurements made on an experimental prototype.The solar installation consists of two photovoltaic panels integrated with air ducts on the top of a building insouthern Spain. The objective is to determine the temperature reached by the photovoltaic module in thisconfiguration. This model considers the processes of heat transfer by radiation and convection on the outside forseveral atmospheric conditions (wind speed, ambient temperature and incident radiation) and for differentgeometrical and physical characteristics of the PV cooling duct (plate area, module performance, emission andabsorption coefficients). Good agreement has been obtained between the experimental data and the results of thismodel.
