Abstract

The invention relates to a facet for solar concentrators, suitable for its use as reflective element of a heliostat, the facet comprising a main body defining a front surface and a back surface. Advantageously, the back surface of the main body is attached to at least three substantially linear ribs, which are arranged substantially parallel along said back surface, and wherein at least one of the three ribs is configured with adjustable anchoring means adapted for their connection to the structure of a solar concentrator. Moreover, the anchoring means are adapted such that the distance between at least one of the three ribs and the structure of a solar concentrator can be varied. The invention also relates to a solar concentrator comprising said facet, and to a method of installation thereof.
