Solar module e.g. photovoltaic module, fastening device for e.g. commercial hall-style building, has retaining element arranged away from body, where retaining element is made of material different from material of body and fixed in body

摘要

The device (10) has a base surface (18) supporting a main body (16) at a laminar support element i.e. flat roof. The main body is made of lightweight material e.g. foam material, mineral wool, polystyrene and elastomer. A retaining element (22) is arranged away from the main body, and holds a solar module e.g. photovoltaic module, where the retaining element is made of a material different from the material of the main body and fixed in the main body. The main body exhibits tapered shape and includes a central recess.
