Title: Two-axis tracker for solar panels and the like

Abstract

A tracker including an outer post having elongated bore and a lower end mounted on a sub-structure, an inner pole rotatably received in the elongated bore, a lower bearing in the bore adjacent a lower end of the outer post and attached thereto to be constrained from lateral movement and mounted on the sub-structure such that a lower end of the inner pole rests on and is supported by the lower bearing, an upper bearing near an upper end of the outer post, a circumferential drive supported on the outer post for rotating the inner pole relative to the outer post, such that substantially a full weight of a load on the inner pole is directly transmitted to the sub-structure and lateral force and torque leverage are placed on a full length of the outer post by way of the upper and lower bearing.

  • This patent describes a wind resistant two axis tracker for reflectors. It comprises: a base; an elevation drive ring, supported in a vertical position by dolly wheels rotatably attached to the base, adapted for centerless rotation on the dolly wheels about a horizontal axis; a reflector attached at two points along the circumference of the elevation drive ring, without direct attachment to the base; and a plurality of support members extending from the elevation drive ring to the periphery of the reflector.
  • The four quadrant, deep concave, linear solar concentration panel has been evolved to meet the need for a practical, low-cost solar energy conversion system, for individual house power supplementation installations. This specific type of solar concentration panel is not designed for a solar photovoltaic conversion arrangement, but for a water steam and flash boiler pipe arrangement where the generated steam is used to drive a rotary steam engine and 110 VAC alternator with a minimum rating of 10 kW/hr. The advocated solar concentration panel has a panel width to flash boiler pipe diameter of about 18:1, which provides a solarmore » concentration ratio of between 22:1 and 27:1, at this point in time. The concentration panel width to height cross-section ratio is approximately 2.5:1, and the base focal line distance to panel height ratio is 1:2.5.« less
  • A versatile single-board controller for two-axis solar tracking applications has been developed and tested on operating solar tracking systems with over two years of field experience. The operating experience gained from the two systems and associated modifications are discussed as representative examples of the practical issues associated with implementing a new two-axis solar tracker design. In this research, open and closed loop control methods were evaluated; however, only the open loop method met the 0.125 tracking accuracy requirement and the requirement to maintain pointing accuracy in hazy and scattered cloudy skies. The open loop algorithm was finally implemented in amore » microcontroller-based tracking system. Methods of applying this controller hardware to different tracker geometries and hardware are discussed along with the experience gained to date.« less
  • This invention is a novel solar tracking mechanism incorporating a number of practical features that give it superior environmental resilience and exceptional tracking accuracy. The mechanism comprises a lightweight space-frame assembly supporting an array of point-focus Fresnel lenses in a two-axis tracking structure. The system is enclosed under a glass cover which isolates it from environmental exposure and enhances tracking accuracy by eliminating wind loading. Tracking accuracy is also enhanced by the system's broad-based tracking support. The system's primary intended application would be to focus highly concentrated sunlight into optical fibers for transmission to core building illumination zones, and themore » system may also have potential for photovoltaic or photothermal solar energy conversion.« less
