1. A solar follower, formed from a plurality of posts (1) and actuator posts (1′) connected to the corresponding foundation (2) or support base in question, posts aligned in parallel, and on which rests, by means of at least one hinge (3) per post, a torque tube (4), on which the means for supporting and attaching the solar panels are assembled, characterised in that in correspondence with each actuator post (1′), next to its hinge (3) a radial arm (5) is disposed solidly connected to the torque tube (4), the arm being hinged at the other end to a linear actuator (6) with screw drive, the bottom end (7) of which is also connected to the actuator post (1′) by means of a joint (8), each linear actuator (6) being actuated by a gear (9) that engages with an endless screw (10) solidly connected to a Cardan-type drive (11-11′-11″-11′″) shared by all the actuators and which is actuated by an electric motor (12), with the particularity that the sections (11″) of the Cardan-type drive that are defined between the linear actuators (6) are fitted closely to the torque tube (4) by means of supports (14).
