Abstract: A photovoltaic system comprises a photovoltaic module attached to a photovoltaic mount frame, the mount frame having a rectangular shape. A deflector is attached to the mount frame by a rotatable deflector and mount frame attachment wherein the deflector pivots around the rotatable deflector and mount frame attachment from a nesting position under the photovoltaic module in the mount frame to an installation position raising at least a first side of the mount frame. A mount foot is attached to the deflector by a rotatable mount foot and deflector attachment wherein the mount foot pivots around the rotatable mount foot and deflector attachment from a nesting position in a mount foot nesting indention in the deflector to an installation position planar to a mounting surface.

Abstract: An optoelectronic device with high band-gap absorbers optimized for indoor use and a method of manufacturing are disclosed. The optoelectronic semiconductor device comprises a p-n structure made of one or more compound semiconductors, wherein the p-n structure comprises a base layer and an emitter layer, wherein the base and/or emitter layers comprise materials whose quantum efficiency spectrum is well-matched to a spectrum of incident light, wherein the incident light is from a light source other than the sun; and wherein the device is a flexible single-crystal device. The method for forming an optoelectronic device optimized for the conversion of light from non-solar illumination sources into electricity, comprises depositing a buffer layer on a wafer; depositing a release layer above the buffer layer; depositing a p-n structure above the release layer; and lifting off the p-n structure from the wafer.

Abstract: A system may include determination of whether solar tracking of a first period of time is to be performed in a first region of sky or in a second region of sky, determination of a target tracker position in a first coordinate system if the solar tracking of the first period of time is to be performed in the first region of sky, and determination of the target tracker position in a second coordinate system if the solar tracking of the first period of time is to be performed in the second region of sky. In some aspects, determination of the target tracker position in the second coordinate system includes subtracting 360° from an azimuth angle in the first coordinate system if the azimuth angle in the first coordinate system is between +180° and +360°, wherein the azimuth angle in the second coordinate system is determined to be equal to the azimuth angle in the first coordinate system if the azimuth angle in the first coordinate system is between 0 and +180°.

Abstract: In one embodiment, a method is provided that determines an image captured from a capture device. For example, a digital camera may be used to take an image of a pattern that is reflected off a solar optical element. The captured image is then compared to a master image. The master image may be an image taken of the pattern reflected off of a second optical element that is of a known distortion. A deviation between the captured image and the master image is then determined based on the comparison. For example, image processing software may use detection techniques to determine if any deviation between the captured image and the master image is present. The deviation may be stored or displayed and a determination as to whether the solar mirror passes or fails the test may also be determined.
