FRESNEL TYPE SOLAR CONCENTRATOR SYSTEM WITH A COLLAPSIBLE STRUCTURE, SELECTED MIRRORS AND SOLAR TRACKING SYSTEM OF MAXIMUM ACCURACY.

摘要

The present invention corresponds to a Fresnel type system of double solar concentration, which enables temperatures of 250°C. The innovation of the present document is mainly based on the use of flat reflectors selected in 3 parts, which together simulate a curve mirror able to reach an efficiency similar to that obtained by curved mirrors and cylindrical-parabolic systems. On the other hand, the system was designed so that the base of the mirrors and their structure in general were completely dismountable without losing structural stiffness and stability. Finally, the system has a solar tracker which unlike the conventional systems has a feedback sensor (element 12) for increasing the accuracy in +/- 0.5 cm, allowing the system to be more efficient with concentration levels compared to cylindrical/parabolic solar concentrators.
