A parabolic reflector having support structure, preferably mounted on wheels for rotation, for supporting a dish framework to which is mounted a multiplicity of adjacently placed reflector members for focusing solar rays on a linear collector. The reflector members are in the form of sheets having the shape of funnel sections, i.e., infundibuliform, to provide a reflective concave surface. Each of the reflector members define slots which are aligned with and adjacent like slots of adjacently placed reflector members for receiving bendable tabs of clip fasteners. The clip fasteners, besides serving to securely connect adjacent reflector members, also include apertures for receiving rivets or other fasteners for attachment to the underlying parabolic framework. The clips include a reflective surface for maximizing reflector efficiency. The linear collector includes a cylindrical, elongated shell for receiving focused solar rays. Heat exchange media flows upward into the collector through a central tube which is separated from the exit passage adjacent the shell by means of solid insulative material to prevent heat exchange between the incoming and exiting heat exchange media.
