Mirror for concentrating solar power devices

A method for manufacturing a mirror system for concentrating solar power devices, said method comprising:

• i) providing a flat and thin glass plate having a thickness between 0.6 and 1.8 mm;
• ii) subjecting said flat and thin glass plate to a tempering treatment, so as to define a surface region of said plate that is pre-tensioned, the surface region being a thickness between 20 and 100 microns in depth from a surface of said plate and then to a silvering treatment, to obtain a flat and thin mirror-finished plate which is flexible, as a consequence of said tempering treatment so that the tensions to which said surface region are subjected during elastic deformation are limited due to the thickness of said surface region;
• iii) providing a curved supporting panel adapted to support and keep the plate inflexed;
• iv) elastically deforming said plate until it assumes the shape of the curved supporting panel limiting;
• v) associating, for complementary shaping by inflection with respect to said panel, said flexible flat and thin mirror-finished plate with said curved supporting panel.
