Abstract: The solar tracker includes a pivoting assembly (2) having solar panels (3) fixed to a rotating shaft (1), a fixed structure with support elements (4, 5, 6) rotationally supporting the rotating shaft (1), a motor-reducer assembly (7) having an irreversible reducer (24) connected to the rotating shaft (1) at a motor connection point (12), and a torsional vibration damping device (8) having a moving member (9) rigidly connected to the rotating shaft (1) at a damper connection point (13) spaced apart from the motor connection point (12) and a stationary member (10) rigidly attached to the fixed structure. Both the moving member (9) and the stationary member (10) comprises elements capable to generate a magnetic field when a movement of the moving member (9) relative to the stationary member (10) occurs, resulting in a damping torque on the rotating shaft (1).

Abstract: The collector/concentrator includes a primary concave reflector (1) supported on a base body (3) obtained by injection moulding, which defines a central support (5) supporting a region around a central opening (6) of the primary reflector (1), a plurality of peripheral legs (7) supporting respective peripheral regions of the primary reflector (1) and first integral connection members (8) connecting said peripheral legs (7) with the central support (5). The peripheral legs (7) have bottom ends (7a) leaning on a substantially flat supporting surface and top ends (7b) located above the peripheral regions of the primary reflector (1) that are in contact with a substantially flat transparent panel (15) supporting a secondary convex reflector (2) that concentrates the solar radiation reflected by the primary reflector (1) towards a receiver unit (18) through the central opening (6).

Abstract: The present invention relates to a single-axis solar tracker and solar power installation. The tracker comprising: a row H1 of coplanar and adjacent solar panels P secured to a horizontal common rotating shaft E1; a support structure wherein said common rotating shaft E1 is rotatably mounted, actuation means with a geared motor M in connection with a part P1 in the form of a circular sector secured to the common rotating shaft E1, and a support base B1 attached to the ground wherein said support structure and said geared motor M are secured. The solar power installation comprises the solar tracker proposed with its actuation mechanism in mechanical connection with a series of actuation mechanisms of other solar trackers included in the installation.
