The invention relates to a roofing (1) made of a plurality of sun protection elements (10) disposed in a plane in a matrix shape, each comprising a Fresnel lens (11) having a focal distance and an elongated absorber (12), wherein two absorbers (12) adjacent in the longitudinal direction thereof are permanently connected to each other, wherein the absorber (12) of a sun protection element (10) is pivotally relative to the Fresnel lens (11) of the sun protection element (10), and at least one linkage element (14) is provided at least between two absorbers (12, 12'') adjacent transverse to the longitudinal direction thereof for transmitting the pivot motion of the one to the other absorber. |
