1. A solar concentrating system for concentrating sunlight by tracking the sun, comprising:
a concentrator support structure, formed with a lower portion at a first peripheral end thereof, and an upper portion at a second peripheral end thereof, the center of mass of the concentrator support structure being more proximal to the lower portion than the upper portion; a concentrator mounted on the concentrator support structure; a base; an annular track mounted on an upper surface of the base, the center of mass of the concentrator support structure being off-axis relative to a curvature center of the annular track; a frame formed with first and second adjacent corners and third and fourth oppositely facing corners; a first enclosure being provided at the first corner, a second enclosure being provided at the second corner, a third enclosure being provided at the third corner and a fourth enclosure being provided at the fourth corner, the enclosures comprising at least one wheel, each of the wheels being positioned on the track, the first peripheral end of the concentrator support structure being mounted on the first and second adjacent corners of the frame, the first and second enclosures being pressed down by weight of the concentrator support structure to a greater degree than the third and fourth enclosures, thereby providing a greater degree of friction between the wheels of the first and second enclosures and the track than a degree of friction between the wheels of the third and fourth enclosures and the track, the first enclosure being connected to a first piston, said first piston is connected to a first guiding element, the first guiding element being placed on the track, the second enclosure being connected to a second piston, said second piston connected to a second guiding element, the second guiding element being placed on the track; at least one of the first and second guiding elements formed with at least one fastening element wherein, when the fastening element is moved towards the track, the guiding element is fastened to the track, and when the fastening element is moved away from the track, the guiding element is released from the track, wherein, when the first piston elongates or contracts and the first guiding element is fastened to the track and the second guiding element is released, the wheels of the first and second enclosure rotate from a first location on the track to a second location on the track, thereby rotating the concentrator support structure around an axis substantially perpendicular to the ground. |
