Abstract: The invention relates to a dynamic solar tracking system for making optimal use of solar energy by means of panels of photovoltaic or thermal plates, in which a modular tracker adopting the configuration of a main beam which can be aligned with others of an identical nature is developed, this assembly of main beams being able to pivot with respect to its longitudinal axis, each of these beams being formed by a variable number of modules formed by profiles which as a whole provide each beam with a configuration by way of a tetrahedron mesh, and in each of which there is assembled a secondary beam structure for supporting the panels of plates, this secondary structure being supported by two side supports with respect to which it can rotate with respect to an axis transverse to the longitudinal direction of the main beams. The assembly incorporates control means for the automatic orientation of the panels, and a weather station for providing information to the control means.
