NOVELTY - The method for producing a concentrator for obtaining solar energy, comprises applying a first plastic layer with a silver mirror layer structure through physical vapor deposition and applying a second plastic layer on the other side of the silver mirror layer structure, where one of the both plastic layers is high transparent and is turned to the solar light source in the later application so that produced laminate is applied by cold flex into a parabolic trough and the concentrator is self-supported.    USE - Method for producing a concentrator useful as a parabolic trough in a parabolic trough collector, and in fresnel mirror collectors, heliostat-reflectors or solar dish concentrator units, medium- or small scale solar thermal units and parabolic form in concentrated photo voltaic for obtaining solar energy (all claimed).    ADVANTAGE - The method ensures economical production of concentrator with improved abrasion-resistance and moisture-resistance.    DETAILED DESCRIPTION - The method for producing a concentrator for obtaining solar energy, comprises applying a first plastic layer with a silver mirror layer structure through physical vapor deposition and applying a second plastic layer on the other side of the silver mirror layer structure, where one of the both plastic layers is high transparent and is turned to the solar light source in the later application so that produced laminate is applied by cold flex into a parabolic trough and the concentrator is self-supported. The first plastic layer is provided on the side to be coated with a metal, with highly transparent primer layer. The side of the metal layer turned away from the highly transparent plastic layer is provided with a metallic protective layer consisting of copper or an alloy of chromium and nickel. Carrier layers turned away from the light source are laterally coated with the metal by means of physical vapor deposition and subsequently the other side of the metal layer is optionally coated with the primer and a highly transparent plastic. The silver mirror layer structure has reflection enhancement stack layers. The metal of the mirror layer is silver and the mirror layer has a thickness of 80-130 nm. The silver mirror layer structure is constructed from an optional primer layer, mirror layer and optional anti-corrosion layer through physical vapor deposition. The highly transparent layer is provided with additives such as inhibitors and/or UV stabilizers. The highly transparent plastic layers consist of different polymer layers, and the individual additives are uniformly distributed and/or separated from one another on the layers. The different polymer layers are polymethylmethacrylate containing layers. The highly transparent layer has a scratch-resistant and/ an antisoiling coating. Optional adhesive layers are present between the individual layers. The laminate has a stiffness, is self-supported and is simultaneously applied from cold formable- into final form. The concentrator has a total thickness of 3-10 mm. An INDEPENDENT CLAIM is included for a concentrator for obtaining solar energy.
