A solar installation 1 is described, with a lens plate 3 which is mounted on a housing 2 and below which is located in the housing 2 a unit, such as a heat exchanger unit or a solar cell unit 5, which is to be irradiated with the concentrated light. In order to improve optical efficiency, there is provision for designing the lens plate 3 with plano-convex or concave-convex lens elements which adjoin one another seamlessly in rows and columns and are square, as seen in a top view, and for the lens elements to be arranged with their plane or concave side facing outwards. <IMAGE> |
