A protective transparent enclosure, such as a greenhouse, encloses a concentrated solar power system having line-focus solar energy concentrators. The line-focus solar energy concentrators have a reflective front layer, a core layer, and a rear layer. The core and the rear layers, when bonded with the reflective front layer, enable the line-focus solar energy concentrator, in some embodiments, to retain a particular form without additional strengthening elements. In some embodiments, the core layer and/or the rear layer are formed by removing material from a single piece of material.
