Arrangement for sunlight concentration has tracking bearer structure consisting only of telescopic variable length control elements joined to base surface and concentrator at opposite ends

摘要

Dual axis parabolic concentrator (1) focuses incident solar radiation onto heat exchanger mounted at focal point, and that tracks sun's position on bearer structure (5), consisting exclusively of telescopic variable length control elements (7) joined to base surface (6) and to concentrator at opposite ends. Bearer structure allows tracking of concentrator in six degrees of spatial freedom An Independent claim is also included for an arrangement for manufacturing telescopic control elements.
