The Modular Multifunctional Solar Structure is an innovative design in the field of Renewable Energy. This system, the schematic diagram of which is shown in FIG. 2, will collect the energy from the sunlight by using lightweight rotary thermal or bivalent photovoltaic solar receivers (A), sandwiched between Support Columns (B) which house the technical services. Because of its modular concept, this structure allows: an easy and progressive assembly in places exposed to the sun, with negative angles of down to 90°; and a microprocessor controlled solar tracking device, with alternative fixed or manually adjustable settings. These features solve the traditional problems associated with solar energy collectors, which include: a fixed position which is confined to specific angles, or a vertical layout, both of which are inefficient in terms of energy recovery; large dimensions and heavyweight collectors, which may need ungainly support structures; and wasted space.
