<p>Concentrated photovoltaic solar system with a Fresnel lens concentrator (1) with a constant facet thickness in a first zone, particularly the central area of the lens (1), then having a constant facet height in a second zone, particularly the peripheral area of the lens (1), in order to maximize the optical efficiency of the lens (1), maintaining the typical system aberrations under control. The concentrated photovoltaic solar system also comprises a secondary optical element 2 with a circular intake face (3) and convex curvature, a section to accommodate a rim (4), and a pyramid section (6), the transverse section changing from a circle into a square in the lower end (7) where the photovoltaic receiver is housed. This system improves optical and thermodynamic efficiency of the existing systems, facilitates the production and installation in the photovoltaic module, and reduces man ufactu ring -related costs.</p> |
