This study is the prediction, depending on time and different geographical and
climatic situations, of different operating parameters: solar radiation, ambient and outlet coolant
temperature, heat exchange coefficients and losses. All these determine, in the absence of
measurements, the efficiency of the system modelled with existing models with respect to these
parameters. These models are usually compared with experimental results. Before modelling, it is
necessary to investigate the different heat transfer and exchange regimes that exist between the
different elements of this system in order to eventually have a system of equations governing this
exchange. The modelling principle is to record the energy balances of each element that makes up the
collector, absorber, glass, insulator and coolant. For this purpose, several models are encountered,
two modelling approaches are also encountered.
