Patent number: 9692352Abstract: A solar array for collecting sunlight that is converted into electricity. The array includes an arrangement of solar collectors strategically positioned on a frame to maximize the amount of sunlight collected in relation to the size of the array. The collectors are plate like members with a reflective side and shaped so that sunlight collected by the reflective side is concentrated at a location away from the reflective side. The collectors are recumbently positioned in rows with their respective reflective sides directed away from the array frame. The collectors are spaced apart so that no collector casts shade on any part of another collector and substantially no sunlight between adjacent collectors.Type: GrantFiled: July 6, 2015Date of Patent: June 27, 2017Assignee: BRIGHTLEAF TECHNOLOGIES, INC.Inventors: James E. Vander Mey, Douglas Helff Kiesewetter, Shane Mark Duckworth

Patent number: 9568218Abstract: An array of solar collectors track the sun based on measured values of power output from the array and from a sun sensor on the array. The sun is tracked by periodically adjusting the altitude and azimuth of the array so the collectors remain pointed at the sun to maximize an amount of solar flux reflected from the collectors. The sun sensor, which detects alignment of the sun, recognizes when relative movement of the sun causes about a 10% reduction in power output of the array. The altitude and azimuth of the array are readjusted based on output from the sun sensor. While the array is being reoriented, power output from the array is monitored, and values for power output versus orientation of the array are recorded. Offset values between the power output, sun sensor output, and the ephemeral equations are calculated by comparing these values during operation.Type: GrantFiled: November 21, 2012Date of Patent: February 14, 2017Assignee: BRIGHTLEAF TECHNOLOGIES, INC.Inventor: Craig Hollabaugh

Non-parabolic solar concentration to an area of controlled flux density conversion system and method
Patent number: 9231142Abstract: A solar conversion system with a solar collector that is shaped to focus reflected sunlight along an area with a substantially constant flux density. The area shape can be resemble a rectangular, square, circular, or other shape. Included with the system is a solar conversion module having a photovoltaic cell that is alignable with the area. The cell converts the focused reflected sunlight into electrical energy when aligned with the area.Type: GrantFiled: October 6, 2010Date of Patent: January 5, 2016Assignee: BRIGHTLEAF TECHNOLOGIES INC.Inventors: James E.

Patent number: 9224898Abstract: 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.Type: GrantFiled: March 14, 2013Date of Patent: December 29, 2015Assignee: BRIGHTLEAF TECHNOLOGIES INC.Inventors: James P. Crimmins, Peter Young, Douglas Kiesewetter
