Abstract
The solar tracking system is a main component of a solar concentrator. A tracking mechanism is proposed and tested under real conditions in a Fresnel prototype at LEPTEN/UFSC with 54m² of mirror area. The receiver is 150mm wide and it is located 3,7m above the mirror field. Analytical and visual tests were performed to verify the accuracy obtained with the tracking device and compared to the target accuracy which is 0,07° in mirror positioning. The Solar Position Algorithm (SPA) provided by the NREL is used to provide the sun position. A sensitive analysis in the inputs for the SPA was done and the results for the sun position showed the inaccuracy can be neglected.
