Abstract: A support device for a solar power generator assembly is provided including a single piece support body for receiving at least part of a solar module and for being appended to a target surface, and having at least one housing formed therein for receiving ballast and attaching points for receiving corresponding projections formed on an attaching device. A solar power generator assembly may include at least one solar module fitted on said support device. Its simplicity and low weight make that a cost effective solar power generator assembly of the integrated type can be obtained that may become part of an existing standard building roof along with architectonical elements, with this being a simple and aesthetic solution for solar energy production.
