Patent number: 8745936Abstract: A rack assembly is provided for mounting solar modules over an underlying body. The rack assembly may include a plurality of rail structures that are arrangeable over the underlying body to form an overall perimeter for the rack assembly. One or more retention structures may be provided with the plurality of rail structures, where each retention structure is configured to support one or more solar modules at a given height above the underlying body. At least some of the plurality of rail structures are adapted to enable individual rail structures o be sealed over the underlying body so as to constrain air flow underneath the solar modules. Additionally, at least one of (i) one or more of the rail structures, or (ii) the one or more retention structures are adjustable so as to adapt the rack assembly to accommodate solar modules of varying forms or dimensions.Type: GrantFiled: August 3, 2012Date of Patent: June 10, 2014Assignee: SunEdison, LLCInventors: Joshua Reed Plaisted, Brian West

Patent number: 8726897Abstract: A collapsible rack assembly for supporting a solar module and methods of assembling the same are provided. The assembly is movable from a collapsed position to an assembled position. The assembly comprises a plurality of collapsible frames, each of which comprises a first leg, a second leg, and a third leg. The first leg extends substantially parallel to a support surface. The second leg extends from the first leg at a first angle relative to the first leg when the frame is assembled and supports the solar module at the first angle when assembled. The third leg extends from the first leg at a second angle relative to the first leg when the frame is assembled. The second and third legs are rotatably connected to the first leg. When in the collapsed position the legs are nested so that one of the legs is disposed within another of the legs.Type: GrantFiled: March 15, 2011Date of Patent: May 20, 2014Assignee: SunEdison, LLCInventor: Linus Eric Wallgren

Publication number: 20130206205Abstract: A solar power system and a solar energy chasing method. Errors may be corrected in the installation area of a solar energy collecting plate with solar cells, particularly, in the installation direction thereof. Therefore, a control angle may be operated and determined, so that the solar cells or the solar energy collecting plate may be rotated precisely in the desired direction. In the case of disposing a plurality of solar energy collecting plates, the solar energy collecting plates may be controlled according to a predetermined rotation angle, thereby increasing solar energy absorbing efficiency.Type: ApplicationFiled: July 9, 2009Publication date: August 15, 2013Applicant: SunEdison, LLCInventor: Boo-Youl Lee
