NOVELTY - The solar reflector comprises planar or curved substrates, which are molded parts made of composite material based on resin reinforced by fibers, fastening components carried integrally by the molded part, a unit for fixing the reflector on a support, a unit for assembling molded parts by interlocking edges of the molded parts, a reflective layer made of silver coating, an adhesion promoter organic coating layer having a thickness of 0.1-20 mu m laid on the reflective layer, and a layer of organic coating for protection against anti-UV corrosion of the reflective layer.    USE - The solar reflector is useful in a solar collector or a solar power plant or for producing electric or steam energy, where the power plant is useful for producing heat and hydrogen, for desalination of water, for producing energy for chemical or oil-bearing industry or for air conditioning (all claimed).    ADVANTAGE - The compact and robust solar reflector ensures efficient electric or steam energy production without the emission of greenhouse gases, enhances service life and performance of the solar power plant, and can be economically fabricated with reduced weight.    DETAILED DESCRIPTION - The solar reflector comprises planar or curved substrates, which are molded parts made of composite material based on resin reinforced by fibers, fastening components carried integrally by the molded part, a unit for fixing the reflector on a support, a unit for assembling molded parts by interlocking edges of the molded parts, a reflective layer made of silver coating, an adhesion promoter organic coating layer having a thickness of 0.1-20 mu m laid on the reflective layer, a layer of organic coating for protection against anti-UV corrosion of the reflective layer, and a layer having a thickness of 1-20 mu m applied in the organic coating layer as an outer surface layer. The molded part has a roughness of less than 20 nm. The fixing unit is anchored or molded into the molded part. The silver coating is applied directly on the substrate. The coating layer is a coating agent for reducing the roughness of the molded part obtained after molding, and has a thickness of 0.1-20 mu m. The molded part is made of a molding composition comprising thermosetting or thermoplastic resin, reinforcing fibers and molding additives. The reinforcing fibers consist of glass fibers. The organic coating layer has a thickness of 10-150 mu m laid on the adhesion promoter organic coating layer or on the reflective layer. The layer having thickness of 1-20 mu m includes antifouling additives consisting of nanometric titanium dioxide having a size of less than 200 nanometers, silver nanoparticles, and nanotubes. INDEPENDENT CLAIMS are included for:    (1) a process for fabricating a solar reflector;    (2) a solar reflector assembly;    (3) a solar collector; and    (4) a solar power plant.
