This book’s authors have developed an automatic manufacturing and assembling system for flat-facet solar concentrators. Thus, a new approach to design a flat-facet solar concentrator that is convenient for automatization has been proposed and described in this chapter. This approach is based on using a precise reference surface for assembling the parabolic dish solar concentrator from small triangular flat mirrors. These mirrors are fixed on the convex side of a reference surface. Each triangular mirror has three special distant stems that provide orientation to the mirror surface parallel to the plane and tangent to the reference surface near the central point of the triangular mirror. After all the triangular mirrors are installed, they are fixed with adhesive tape made from paper or fiberglass filled with epoxy resin. Additional reinforcing ribs may be glued if necessary. The prototype of this concentrator is described in this chapter.

A new manufacturing approach to the support frame of a solar concentrator with plane mirrors is also described. The main idea of the new approach is using the parabolic dish reference surface as a mold for the support frame of the solar concentrator. One mold can be used to manufacture many support frames. For this reason, the mold can be made much more precisely than individual support frames. To create the first solar concentrator prototypes, the parabolic dish of a TV antenna was used as a mold for the support frames (Fig. 7.30). If the solar concentrator has a relatively small size, it is possible to make the support frame with two or three layers of fiberglass tissue filled with epoxy resin. This support frame is molded on the convex side of the parabolic dish antenna. After the epoxy resin hardens, small flat mirrors are glued onto the concave face of the support frame.
