Abstract

Solar concentrator truss assemblies and arrays of solar concentrator truss assemblies are disclosed. The solar concentrator truss assembly has a V-shaped frame joined with a solar panel to form a triangulated truss. The solar concentrator truss assembly is lightweight and strong, and does not require extensive additional structural support for installation. The array of solar concentrator truss assemblies is motion controlled by a computer to move the array into preferable positions with regards to sunlight.

Claims

1. A solar concentrator truss assembly, comprising:

a generally V-shaped frame including an inner surface, the inner surface including a first and second concentrating portion, the inner surface including an unexposed portion located between the first and second concentrating portion; and

a solar panel including a sun-facing surface and a bottom surface, the solar panel received by the inner surface;

wherein the solar panel bridges the inner surface to form a truss with the generally V-shaped frame, such that the sun-facing surface and the first and second reflective portions are exposed to each other, and the bottom surface is exposed to the unexposed portion.

2. The solar concentrator truss assembly of claim 1, wherein the first and second concentrating portions are separated from one another by an angle ranging from 60 to 90 degrees.

3. The solar concentrator truss assembly of claim 1, wherein the first and second concentrating portions include reflective adhesive films disposed thereon.

4. The solar concentrator truss assembly of claim 1, wherein the generally V-shaped frame is constructed from a single piece of sheet metal.
