ABSTRACT:
A nontracking concentrating solar collector is provided in which a series of parallel parabolic reflector segments reflective on both sides thereof are disposed with their focal points lying in a plane which is at approximately a right angle to the angle of incident solar radiation which is received in the space between the upper ends of the reflector segments. The length of the reflector segments is selected so that the incident radiation is reflected back and forth between the segments until an even numbered reflection, preferably either the fourth or the sixth reflection, emerges downwardly from between the reflector segments in a narrowed beam which is received by a solar collector. Preferably, the collector is a tube carrying a heat transfer medium which is positioned beneath the reflector segments other than the first segment in the series, and paralleling said segments, and a secondary reflector is positioned beneath the tubes to concentrate the reflections emerging from the reflector segments upon the tubes.
