US Patent 7444816 Solar power station

A solar power station includes a solar panel assembly, having a substantially planar solar panel, and first, second and third towers. Each of the towers includes multiple vertically stacked floors and a main bearing structure pivotally mounting the solar panel assembly to the tower upper end. Each of the floors includes an arrangement of robots that are connected to each vertically adjacent floor. At least some of the robots including hydraulic jacks. A controller selectively actuates the hydraulic jacks, such that each of the towers is individually extendable from a bottom position to an extended position. Selectively moving one or more of the towers rotates the solar panel about one or both of the axes, whereby the solar panel is maintained at an optimal orientation for collecting solar power.
