Abstract: Motorized rotational drive system (8) for rotating a framework about an axis of rotation, preferably a horizontal axis of rotation, for a solar collector tracker support system, said motorized system comprising: two ring gear sectors (80) extending in two planes orthogonal to the axis of rotation and provided with means of attachment to said framework; a transmission shaft (82) supporting two pinions (81) in mesh with the corresponding ring gear sectors (80) for synchronized rotation of said ring gear sectors (80); and a motorized drive means for driving the rotation of said transmission shaft (82).

Abstract: A linearly-arranged solar array (1) comprising at least two tracking support systems (2) for solar panels, wherein each tracking support system (2) can be oriented according to one single main axis of rotation (20), wherein the tracking support systems (2) are aligned on the same line with their main axes of rotation (20) being coincident, wherein each tracking support system (2) comprises: a fixed ground anchor structure (21); a movable structure including a platform (22) for supporting the solar panels, rotatably mounted on the fixed structure (21) about the main axis of rotation (20); a mechanical system (24) for driving the movable structure in rotation about the main axis of rotation (20).

Abstract: Tracker support system (1) for solar sensor comprising:—a fixed structure (2) for anchoring to the ground exhibiting several anchoring points (21) defining an anchoring plane and separated from one another by distances termed ground prints, including a larger ground print distance (DE) established between at least two anchoring points (21); and—a movable structure (3) comprising:—a first armature (4) mounted rotatably on the fixed structure (2) according to a vertical axis of rotation (AV); and—a second armature (5) defining a support plane for the solar sensors and mounted rotatably on the first armature (4) according to a horizontal axis of rotation (AH) extending to a distance termed the zenith height from the anchoring plane; said tracker support system (1) being noteworthy in that the ratio of the largest ground print distance (DE) to the zenith height is included in a span ranging from 0.5 to 1.5, and preferably in a span ranging from 0.8 to 1.2.
