OPEN ACCESS
In the field of thermal conversion of solar energy, several studies have been conducted to model different parameters related to this process. But in all the models encountered, the parameters obtained are more or less close to reality. For us the best is the one that best reflects the variation of the modeled parameter. In fact, the confrontation of the values resulting from the experimental measurements makes it possible to judge the accuracy of the established model. In this context this study was conducted. The aim of the study is to model global solar radiation according to the ambient temperature, geographical location of the site, date and time. The obtained models are compared with the experimental results. In our experimental study we simulated the model developed by comparative study with the model of M-Y Mechraoui, showed that the experimental results are in good agreement with those given by the model developed, which is in agreement with that of M. Capderou,which presents a better estimate of global solar radiation with a small error between the measured values and those calculated. The set of studies was done for the Biskra site, horizontally.
