A solar concentrator is described for illuminating the interior of a building through a side wall thereof. The concentrator consists of: a stationary reflective collector located to view the sky and having discrete planar collector surfaces mounted in abutting relationship, the collector surface installed at an angle with respect to the vertical different from the angle of installation of the abutting collector surfaces; a stationary reflective reflector positioned to receive direct solar energy reflected by the collector and oriented to reflect such energy toward a target within the building, the reflector having a plurality of discrete planar reflector surfaces the reflector surface mounted in abutting relationship, the reflector surface installed at an angle with respect to the vertical different from the angle of installation of the abutting reflector surfaces; a low angle shield means for preventing direct solar rays from entering unreflected into the building between the collector and the reflector and penetrating a horizontal plane above the floor of the building, the horizontal plane spaced from the floor a distance substantially equal to the height of the eye of an occupant standing on the floor of the building, the low angle shield means including an opaque material and being affixed to the reflector; and a shield means for preventing rays reflected by the collector and the reflector from penetrating the horizontal plane, the shield means affixed to the building and extending in a generally horizontal direction.
