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. |
