Abstract
A solar energy concentrating and collecting arrangement and method in which a semi-cylindrical oblong concave reflector/concentrator forms the roof of a house, school or other building, particularly a heat utilization building. A collector is movably supported in spaced relation above and along the length of the oblong roof/reflector concentrator, for pivotal movement, by a solar reflection energy sensing and seeking drive control arrangement, to a zone of maximum confluence of solar energy rays reflected from the roof/reflector concentrator as a result of variations of sun path during the various parts of the year and also to further accommodate each day's movement of the sun. Movement of the collector is by pivotal movement about an axis parallel with the center of curvature or curvatures of the roof/reflector concentrator and disposed adjacent the roof/reflector concentrator. The roof/reflector has a plurality of 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 concentrated solar energy collected b…
