Abstract: The single axis solar tracking assembly comprises a plurality of spine sections (2) connected to one another by universal joints (10), supporting legs (3) rotatably supporting the spine sections (2) on the ground, a plurality of brackets attached to each spine section (2), a plurality of rib members (4) connected to the brackets, and solar panels (5) secured to the rib members (4). The rib members (4) are moveable between a folded position and a deployed position. An auxiliary shaft is located between adjacent universal joints (10) connected to adjacent spine sections (2). First and second crossed spine hinge axes of the universal joints are arranged so that the spine sections (2) can be fold at right angles to the auxiliary shaft and the spine sections (2) can be fold in a zig zag fashion into a compact storage position in which the solar panels are arranged in adjacent parallel planes.
