SOLAR ENERGY REFLECTOR
First Claim
1. A solar energy reflector (1) comprising a mirror (5) with no copper layer laminated to a supporting sheet (7) by means of a bonding material (6), 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 (8) 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 (8) is different from the bonding material (6).
