A solar collector of the non-tracking fluid circulating type which is formed of light weight materials and comprises a frame supporting fluid circulating tubes having a light absorber disposed axially therein and lined with retroreflective cube-corners. The tubes are placed in semicircular reflectors and enclosed by a transparent barrier sheet and cover having light anti-reflective coatings.

A solar collector comprising a plurality of generally semicylindrical reflectors disposed in parallel relationship with the open sides of said reflectors disposed in a plane, a transparent hollow tube disposed within each reflector and adapted to carry a liquid from one end toward the other, said tubes having on the interior surface thereof an array of nested cube-corners, and absorber means disposed in said tube to absorb sun energy efficiently to heat the surface thereof, said transparent tube interior surface defined by cube-corners having an index of refraction substantially different from that of air.
