A focused solar heating system is provided having a focusing reflector which is generally scoop-shaped. A solar collector plate is mounted on the front of the focusing reflector to directly accept direct solar radiation and diffuse radiation which strikes the front surface of the plate. The remainder of the entrance aperture of the focusing reflector accepts both on- and off-axis solar direct and diffuse radiation which is reflected by the focusing reflector and applied to the rear surface of the solar collector plate. The focusing reflector has a concave reflective surface made up of first and second merging curves which are optimized so that the front and rear surfaces of the solar collector plate accept the larger solid angle of both direct and diffuse rays from the sun and provides an optical gain which increases the efficiency of the system. The solar collection system may be incorporated in a vertical wall of a building and made partially transmissive, or may be incorporated in a separate structure for supplementing the heating or cooling of a building or providing hot water therefor. |
