  • Patent number: 9847750
    Abstract: A solar energy collection system for converting solar energy to electricity that includes solar arrays mounted on a frame. Each array is set on a tracker head that is supported on a pedestal; each pedestal mounts onto a beam. Elevators pivot the arrays, where each elevator is made up of a shaft with a threaded end coupled to a drive nut. An upper end of each drive nut gimbal mounts to a portion of the tracker head; rotating a lower end of each shaft raises or lowers the drive nut, thereby pivoting each array. The vertical shafts are ganged together and driven by a single motor. Further included with each pedestal are azimuth orientation shafts that also mount to each tracker head. Rotating each orientation shaft adjusts an azimuth of an associated array. The orientation shafts are ganged together and are rotated by a single motor.

  • Publication number: 20160218667
    Abstract: A method and apparatus for capturing solar energy for use with a structure. A solar energy system collects solar energy, some of which is converted into electricity and some of which is stored in subterranean thermal banks. Waste heat is formed in solar cells during the conversion of solar energy into electricity. A fluid flow system is provided that transfers heat from the solar cells into a subterranean formation via wellbores that penetrate the subterranean formation. The heat remains in the formation and is selectively transferred to the structure through the fluid flow system.
