Abstract: A sun tracking system includes a reduction device of a servo motor, multiple shafts, multiple couplers, and at least two rows of cylinders and each row having at least two cylinders, a solar panel, multiple pivotal connection units and multiple sliding units. The reduction device of a servo motor drives the cylinders of the first and second rows of cylinders which drive other cylinders. The cylinders of the first row of cylinders are pivotably connected to the solar panel and the cylinders of the second row of cylinders are movably connected to the solar panel. By the cylinders of the same row moving upward or downward while the cylinders of the other row moving downward or upward, the panel is controlled to aim the sun.
