A parabolic trough solar energy collector including an elongated support with a plurality of ribs secured thereto and extending outwardly therefrom. One surface of said ribs is shaped to define a parabola and is adapted to receive and support a thin reflecting sheet which forms a parabolic trough reflecting surface. One or more of said collectors are adapted to be joined end to end and supported for joint rotation to track the sun. A common drive system rotates the reflectors to track the sun; the reflector concentrates and focuses the energy along a focal line. The fluid to be heated is presented along the focal line in a suitable pipe which extends therealong.

A solar energy collector comprising a collector assembly including a central elongated rib support, a plurality of spaced parallel ribs formed of sheet material secured to and extending outwardly in opposite directions from said rib support with the upper edges of said ribs defining an elongated parabolic surface, a thin sheet of reflecting material supported on the upper edge of said spaced ribs to conform to said parabolic surface to form a parabolic reflector for collecting solar energy and focusing the collected energy along a focal line, and retainer means cooperating between the ends of said ribs and adjacent edges of said sheet to hold the sheet in engagement with said ribs; support means for engaging said elongated rib support to support the collector assembly; and, means disposed at the focal line of said parabolic reflector to receive energy collected and reflected by said parabolic reflector.
