A solar energy concentrating and collecting arrangement in which a plurality of laterally adjacent partial cylindrical oblong concave reflector-concentrators form the roof of a house, school or other building, particularly a heat utilization building, with a corresponding plurality of ganged movable collectors movably supported in spaced relation above and along the length of the oblong roof/reflectors. Each roof/reflector-concentrator has at least three radii, for enabling accommodation of wide variations of the sun angles during the various seasons of the year and during each day of a given season, while still affording a desired concentration of solar energy on the collector. The roof/reflector-concentrators are preferably substantially symmetrical in curvature and width about a vertical central plane, and face vertically upward to form an inverted modified cycloid-like surface.

A solar energy concentrating and collecting arrangement, comprising a generally upwardly facing concave generally partial cylindrical trough reflector fixedly positioned during operational reflection and having three radii, each radius forming an effective overall arc segment along the effective partial cylindrical length of said reflector, the center of radius of each of said radii lying on a respective axis line extending along the longitudinal extent of said partial cylindrical trough reflector, and a collector having a longitudinal extent extending along the length said reflector and disposed in parallel spaced relation from the effective reflecting surface of said reflector and movable support means movably supporting said collector for movement transversely of its longitudinal extent across a portion of the arcuate width of said reflector to enable selected positioning of said collector at varied lateral positions across the width of said reflector as a function of sun angle of elevation for maximizing pickup of reflected solar energy from said operationally fixed position reflector, said reflector having a first concave radius of curvature along the effective length of a first cylindrical concentrating reflective arc segment thereof, and a second and third lesser concave radii of curvature along the effective length of second and third concentrating reflective cylindrical arc segments thereof said first large radius cylindrical concentrating reflective arc segment lying between said second and third lesser radii arc segments, said reflector thereby providing a generalized spatially movable focal zone laterally spatially movable relative to said reflector through and as a function of a wide range of transverse sun intercept angles relative to the reflector, and each of said lesser radii cylindrical arc segments being inclined at a lesser angle to the vertical than said first concave concentrating larger radius reflective arc segment.
