NOVELTY - A solar reflecting mirror comprises transparent substrate (28) having a first surface (30) designated to face a source of solar energy; a second surface (32) opposite to the first surface; an opaque solar reflecting coating provided on the second surface; and a transparent reflecting coating over the first surface to increase the percent reflection of at least one of the absorbable wavelength of the electromagnetic spectrum in a direction away from the first and the second surface of the transparent substrate.    USE - As solar reflecting mirror (claimed), used for converting solar energy to electric or thermal energy.    ADVANTAGE - The sun's rays absorbed by the glass substrate of the primary mirror and the glass substrate of the secondary mirror reduces the solar energy incident on the receiver. The loss of solar energy by absorption is reduced at selected wavelengths by 20-35 (preferably 35-40, especially 40-45)% by increasing the reflection of selected ones of absorbable wavelengths of electromagnetic spectrum away from the glass substrates. In this manner, the percent absorption of selected ones of absorbable wavelengths of electromagnetic spectrum passing into glass substrates is reduced.    DETAILED DESCRIPTION - A solar reflecting mirror comprises a transparent substrate (28) having a first surface (30) designated to face a source of solar energy; a second surface (32) opposite to the first surface; an opaque solar reflecting coating provided on the second surface; and a transparent reflecting coating over the first surface to increase the percent reflection of at least one of the absorbable wavelength of the electromagnetic spectrum in a direction away from the first and the second surface of the transparent substrate. The glass substrate has a composition comprising an ingredient that absorbs at least one wavelength of the electromagnetic spectrum defined as absorbable wavelengths.
