  • Patent number: 7888587
    Abstract: A modular shade system with solar tracking panels includes a series of generally North-South oriented, spaced apart torque tubes, each torque tube having an axis, a series of panels mounted to at least some of the torque tubes to create spaced-apart rows of panels along the torque tubes, at least some of the panels being solar collector panels. The system also includes a shade structure, positioned at a selected location between selected ones of the torque tubes and above the support surface so to provide an enhanced shaded region thereunder, and a support structure. The support structure includes a first mounting assembly mounting each torque tube above the support surface for rotation about the axis of each torque tube and a second mounting assembly supporting the shade structure at the selected location. The system further comprises a tilting assembly selectively rotating each torque tube about its axis.

  • Patent number: 7888588
    Abstract: A tracking solar collector assembly includes solar collector support structure, with at least one solar collector mounted thereto and first and second spaced apart pivotal support points defining a tilt axis, Southside supports, with first pivot connectors, and North side supports, with a base, a second pivot connector, and one or two support elements connected to the base and to the second pivot connector at the ends thereof. The first and second support points are pivotally connected to and supported by the first pivot connectors and by the North side supports, respectively. The assembly also includes a tilting assembly causing the solar collectors therewith to tilt in unison.

  • Patent number: 7807918
    Abstract: A modular shade system comprises a support structure supporting modular panels. The support structure defines a first area having a length and a width. The modular panels have upper, exposed surfaces and lower surfaces and are mounted to and supported by the support structure. The modular panels cover at least about 80% of the first area. The modular panels comprise PV panels and supplemental panels, the supplemental panels providing a feature other than shading and optionally providing shading. Protective panels may be mounted opposite the lower surfaces of the PV modules. A protective panel may so be used when the PV module is part of an installation other than a modular shade structure.

  • Publication number: 20100179678
    Abstract: Pressure equalization between upper and lower surfaces of PV modules of an array of PV modules can be enhanced in several ways. Air gaps opening into the air volume, defined between the PV modules and the support surface, should be provided between adjacent PV modules and along the periphery of the array. The ratio of this air volume to the total area of the air gaps should be minimized. Peripheral wind deflectors should be used to minimize aerodynamic drag forces on the PV modules. The time to equalize pressure between the upper and lower surfaces of the PV modules should be maintained below, for example, 10-20 milliseconds. The displacement created by wind gusts should be limited to, for example, 2-5 millimeters or less. For inclined PV modules, rear air deflectors are advised for each PV module and side air deflectors are advised for the periphery of the array.

  • Patent number: 7554030
    Abstract: A tracking solar collector assembly includes Southside supports, North side supports and support structures. Each support structure has pivotal support points defining a tilt axis and supports at least one solar collector. First support points of first and second support structures are pivotally connected to first and second Southside supports. A second support point of the first support structure is pivotally connected to first and second North side supports. A second support point of the second support structure is pivotally connected to second and third North side supports. A tilting assembly causes the solar collector support structures and the solar collectors tilt in unison. A tracking solar collector may comprise a torsion tube rotatable about a torsion tube axis; with the solar panels secured to the torsion tube at an angle with the solar panels located entirely above the torsion tube at noontime.

  • Patent number: 7435134
    Abstract: An electrically conductive mounting/grounding clip, for use with a photovoltaic assembly of the type having an electrically conductive frame, comprises an electrically conductive body. The body has a central portion and first and second spaced-apart arms extending generally perpendicular to the central portion. Each arm has an outer portion with each outer portion having an outer end. At least one frame surface-disrupting element is at each outer end. The central portion defines a plane with the frame surface-disrupting elements pointing towards the plane. In some examples each arm extends from the central portion at an acute angle to the plane.

  • Patent number: 7328534
    Abstract: A barrier, such as a PV module, is secured to a base by a support to create a shingle assembly with a venting region defined between the barrier and base for temperature regulation. Water resistant junctions may be formed between the bases of adjacent shingle assemblies of an array of shingle assemblies. The base may include an insulation layer underlying a water barrier. The base may also include a waterproofing element; the width and height of the barrier may be shorter than the width and height of the waterproofing element.
