Publication number: 20110030672Abstract: A mirror or other reflecting surface is used for collecting and reflecting incident solar radiation. The mirror is supported for independent motion about a pair of axes. An accelerometer generates signals representative of an amount and direction of motion of the mirror about each of the axes. Motors or other drive mechanisms independently drive the mirror about each of the axes. A tracking device provides information about the current position of the Sun. A control is connected to the accelerometer, the motors and the tracking device for maintaining a predetermined optimum orientation of the mirror as the Sun moves across the sky. Position sensors that sense the position of the mirror relative to the earth's magnetic field may also be employed.Type: ApplicationFiled: October 8, 2010Publication date: February 10, 2011Inventor: Mark S.

Patent number: 7252083Abstract: A structure (26) for supporting an array (22) of solar panels (24) in a solar energy collection system (20) includes a support assembly (42) formed from a rigid subassembly (44). The subassembly (44) includes an elongated truss (68), a base (46) coupled to the truss (68) for attachment to a footing (48), and posts (50) extending from a top edge of the truss (68). The structure (26) further includes torsion tubes (34), each of which is pivotally retained by one of the posts (50) to form parallel rows (32) of torsion tubes (34). A number of rigid subassemblies (44) can be interconnected to further increase the number of rows (32) of the system (20). The solar panels (24) are attached to the torsion tubes (34) to form the array (22), and a drive mechanism (38) pivots the torsion tubes (34) via a single elongated actuator and multiple torque arms (90).Type: GrantFiled: July 18, 2005Date of Patent: August 7, 2007Assignee: Arizona Public Service CompanyInventor: Herbert T. Hayden

Patent number: 7202457Abstract: A sun-position tracking system for a solar module has a base on which a rotary plate is supported. Several generally parallel fixed rods fixed to the plate have outer ends extending outward past the plate. A planar frame is pivoted on the rod outer ends about a generally horizontal frame axis between a down position with the frame lying on and substantially parallel to the plate and an up position extending at an acute angle to the plate. The solar module is carried on the frame and lies in a panel plane above the rods and plate. A sector gear fixed to the frame outside the outer edge of the plate and wholly below the plane is engaged by a pivot drive mounted on the rod outer ends and wholly below the plane the frame between its positions.Type: GrantFiled: May 28, 2002Date of Patent: April 10, 2007Assignee: Giselher FenglerInventors: Elfi Janus, Wolfram Berger

Patent number: 6557804Abstract: A non-imaging solar concentrator having a primary concentrator and a turntable. The primary concentrator is mounted to the turntable such that it is rotatable about a turntable axis and a secondary axis that is orthogonal to the turntable axis. Rotation of the primary concentrator about the turntable and secondary axes permits the primary concentrator to be positioned anywhere within the visible sky, even when a solar offset angle of 90 degrees is not used.Type: GrantFiled: December 5, 2001Date of Patent: May 6, 2003Assignee: The Boeing CompanyInventor: Joseph P.

Publication number: 20030034029Abstract: A solar collector array is formed of multiple parallel rows of solar panels, each said row being made of one or more building blocks with an east-west oriented torsion tube defining an east-west axis for the row, an array of flat generally rectangular solar panels, and a set of panel rails and rail claims attaching the panels onto the torsion tube. A row of piers aligned on the east-west axis each have a footing that is supported in the earth, and a pier cap affixed onto a top end of the pier. The pier cap holds the torsion tube non-rotationally such that the torsion tube and panels are held at a preset elevation angle. The torsion tube may serve as a conduit for power conductors from the panels.Type: ApplicationFiled: August 15, 2001Publication date: February 20, 2003Inventor: Jefferson Shingleton
