Mono-axial system consisting of 1 row of vertical modules, for tables of 18/22 modules. The system is designed to adjust to the annual tilt of the installation area. Movement of the modules operated by an electric motor in low voltage that allows the adjustment of the inclination to be chosen, with re-entry in horizontal at night or in case of windiness exceeding the optimal values of the installation area. The control board can be used up to 7 systems with 22 modules. The structure uses the international patent for fixing to the ground through cages filled with inert material locally sourced; this facilitates installation and reduces logistics, organizational and special equipment costs. The plant is removable and totally reusable.
