NOVELTY - The solar reflector comprises an abrasion-resistant coating, a reflective metal layer located below the abrasion-resistant coating, an adhesive layer located below the reflective metal layer, and a polymer film layer. The polymer film layer is provided between the abrasion-resistant coating and the reflective metal layer and provided between the reflective metal layer and the adhesive layer. The solar reflector further comprises a protective layer directly located below the reflective metal layer. The abrasion-resistant coating comprises UV absorbers.    USE - The reflector is useful for concentrating and collecting solar radiations, and in a solar tube, light shelf, laminated sheet or lighting reflector application (all claimed).    ADVANTAGE - The solar reflector can be economically constructed with high reflectance, increased abrasion resistance, excellent UV stability, improved mechanical integrity and enhanced flexibility.    DETAILED DESCRIPTION - The solar reflector comprises an abrasion-resistant coating, a reflective metal layer located below the abrasion-resistant coating, an adhesive layer located below the reflective metal layer, and a polymer film layer. The polymer film layer is provided between the abrasion-resistant coating and the reflective metal layer and provided between the reflective metal layer and the adhesive layer. The solar reflector further comprises a protective layer directly located below the reflective metal layer. The abrasion-resistant coating: comprises UV absorbers; prevents more than one percent decrease in specular reflectance of the solar reflector when subjected to 30 cycles of abrasive exposure from a Taber wheel loaded at 250 g; absorbs less than an average of four percent of electromagnetic radiation incident to the solar reflector having wavelengths of 400-2500 nm; has a thickness of 1-25 microns; is present in physical contact with the polymer film layer; protects the polymer film layer, reflective metal layer, and adhesive layer from abrasion damage caused by electromagnetic radiation incident to the solar reflector having wavelengths of 280-400 nm; transmits less than 5% of electromagnetic radiation incident to the solar reflector having wavelengths selected of 250-350 nm and greater than 33% of electromagnetic radiation incident to the solar reflector having wavelengths of 350-400 nm; is a topmost layer of the solar reflector; and is provided by a slot die application technique. The adhesive layer comprises a pressure-sensitive adhesive, and is chemically inert with respect to the reflective metal layer and the protective layer. The polymer film layer: comprises UV absorbers; prevents transmission of 95% of electromagnetic radiation incident to the solar reflector having wavelengths of 200-380 nm; transmits 96%of electromagnetic radiation incident to the solar reflector having wavelengths of 380-2500 nm; and has a thickness of 10-150 microns. The reflective metal layer has a thickness of 0.05-0.15 micron. The protective layer has a thickness of 0.002-0.15 micron. The adhesive layer has a thickness of 5-100 microns. A surface of the polymer film layer is treated by an adhesion promotion technique. The adhesion promotion technique comprises a corona discharge, plasma, atomic layer deposition, or chemical etch adhesion promotion technique. The adhesive layer is provided on a substrate. The substrate comprises sheet metal, hard polymer, sturdy polymer, thermally formed polymer, or removable backing. INDEPENDENT CLAIMS are included for:    (1) a method for collecting solar radiation; and    (2) a method for concentrating solar radiation.
