Sun position tracking methods are of great use to optimize energy of photovoltaic modules. As a matter of fact, its performance still remains low. In this paper, two tracking methods have been implemented in rapidly changing weather conditions: An automatic sun tracking and a manual sun tracking method. For the first method, an automatic 1-axis sun tracking prototype has been realized. For the second technics, sun position angle have been calculated from astronomical formula and from irradiance mathematical modeling, the solar panel have thus been positioned manually along the day accordingly. Measurements were recorded during sunny and cloudy days, in the University of Ngaoundere at the latitude 7.418° N and the longitude 13.542° E. Experimental data have been used for performance comparison purpose. This study shows that the automatic smart sun tracking offers better performance than the manual tracking. Nevertheless the manual tracking offer good performance for sunny skies in comparison to the energiy gained when the panel remains fixed. |
