Portable system of photovoltaic panels with biaxial solar tracking structure and folding system for its transport and storage

A portable system of photovoltaic panels (4) with 2-axes solar tracking system comprising:

• a base bottom substructure (1) that includes 3 radial legs (1.2) shaped in the form of a tripod with removable end supports (1.6) joined with the radial legs (1.2) by means of double tilted rod (1.13) joints, a central cylindrical piece (1.3) where the radial legs (1.2) are joined and that contains in its center an azimuth bottom joint axis (1.4), and a top restraint ring (1.1) that is joined to the radial legs (1.2) by their ends by means of brackets (1.5);
• a mid substructure (2) that is joined with the bottom substructure (1) by means of the azimuth joint, and that comprises a pole (2.1), a bottom handle (2.2) and a set of azimuth gears (2.3, 1.8) comprising an azimuth large gear (2.3) and an azimuth small gear (1.8);
• a top substructure (3) that is joined with the mid substructure (2) by means of an elevation horizontal axis joint, and that comprises a supporting frame (3.1) for the panel (4), a top retractable handle (3.4) and a lattice (3.2) that integrates a set of elevation gears (3.3, 2.5) comprising an elevation large gear (3.3) and an elevation small gear (2.5);
• and a solar panel (4) that comprises 4 semi-flexible subpanels that is assembled to the top substructure (3) through the supporting frame (3.1) by means of fixation screws (4.3) and that consists of 4 subpanels pyramidal in shape with fixation hollows (4.2) between internal cells for the insertion of the fixation screws (4.3), and designed with a cut-off edge (4.4) in each central joint of the subpanels in order to open a space that allow the unfolding of the top retractable handle (3.4), and with connexion boxes (4.5) in the corners close to the central joint.
