Résumé
This paper presents an experimental study of the quantification of global solar radiation through a solar tracker system. Using an experimental two-axis sun-tracking device, we first experimentally measured solar radiation at Joseph KI-ZERBO University site, and then compared results with those obtained with a fixed system inclined at an angle of 12.350°. The results of this experimental study
show that, on a clear-sky day, solar irradiation with a solar tracker is between 800W.m–2 and 1000W.m–2 between 8 a.m. and 4 p.m., i.e., an insolation duration of around 8 hours. What’s more, when using solar tracking systems, we see an overall radiation gain of around 52.33% compared with fixed systems tilted by an angle corresponding to the latitude of the site.
