SOLAR ENERGY REFLECTOR
First Claim
1. A solar energy reflector comprising a mirror with no copper layer laminated to a supporting sheet by a bonding material, wherein the edges of the mirror are provided, at least on a portion forming the major part of their height and closest to the supporting sheet, with an edge protection made of a material comprising at least one of the group consisting of silicone, polyurethane and acrylic, and wherein the material forming the edge protection is different from the bonding material.
