Abstract: The invention is a method for constructing solar energy mounting apparatuses in which structural elements of the apparatus are cast in molds formed on a substantially horizontal surface. A self curing compound, such as reinforced concrete, is used as the material for the structural elements. After curing for sufficient time to achieve strength necessary to allow for handling, the structural element is hoisted into place in a substantially non-horizontal position. Alternatively, the structural element may be used in the moving portion of a solar energy mounting apparatus that performs a tracking function. The use of reinforced concrete in the structural elements of solar energy mounting apparatuses allows for cost reduction over the prior art in that reinforced concrete is less expensive on a unit strength basis than other typical structural materials, such as steel and aluminum.

Abstract: The invention is a wind resistant celestial tracking apparatus that uses gravitational forces acting on the moving elements of the structure to provide overturning resistance. A molded self curing compound, such as reinforced concrete, is used as the structural material that provides the mass, and thus the gravitational overturning resistance that reduces or eliminates the need for a massive ballasted or dug-in foundation. The combination of these features potentially lowers cost significantly over that of tracking apparatuses found in prior art. The invention is appropriate for use in any celestial tracking application with any number of axes of motion, but is particularly useful in two axis solar energy collection systems.

Abstract: An apparatus for networking solar tracking devices 32. The system includes one or more solar tracking devices 32, each comprising tracking controller 16. Tracking controllers 16 form wireless mesh communications network 18 managed by network manager 14. Tracking controller 16 receives operating data from and sends monitoring data to host computer 10. This operation and monitoring data travels across wireless communications network 18. Host computer 10 connects to wireless mesh communications network 18 either directly or via any communication channel 12 connected to any node on wireless mesh communications network 18.
