Abstract

Solar trough apparatuses are disclosed, where a heat transfer fluid conduit remains fixed in a focal of a solar trough as the solar trough tracks the sun. The support structures can be ring or arcuate structures, where rotation is about their central axis and the trough is support in them so that the focal zone is coincident with the axis of rotation and the conduit is situated in the focal zone eliminating the need for articulated or flexible conduit.
