Support Frame Assembly And Method Of Forming A Support Frame Assembly

Abstract

At least one aspect of the present invention is related to a support frame assembly for supporting a solar device, such as an array of mirror elements and / or photovoltaic panels. The support frame assembly includes a plurality of support arm assemblies, each of which includes a pair of rails and a plurality of web structures interconnecting the rails. Specifically, each of the web structures has a base which is attached to one of the rails and a pair of legs extending towards and attached to the other of the rails. The web structures are preferably formed through a single stamping process with at least one of the web structures being at least partially in a nesting relationship with another of the web structures.

AI Technical Summary

Benefits of technology

The present invention provides a support frame assembly for supporting a solar device. The assembly includes at least one support arm assembly with at least two rails that converge towards each other. The assembly also includes at least two web structures that interconnect the rails. The web structures have a base attached to one of the rails and two legs extending to the other rail. The web structures can be easily adapted to support arm assemblies with various shapes, sizes, and designs. The web structures allow for less strict tolerances between components and reduced assembly time and cost as compared to other known support frame assemblies. The web structures are shaped and sized to at least partially nested within the opening of another web structure, which allows for more efficient shaping and shipping of the components. The web structures are formed of a different, lighter material than the rails, which reduces the mass of the support arm assemblies without compromising their structural integrity.

Problems solved by technology

As solar energy devices are now being required to satisfy ever-larger energy requirements, they necessarily become physically larger.

The weight of the support structure itself, and that of the attached solar devices along with wind loads and / or snow loads, can cause significant loads on the support structure.

As such, tracking systems are found in virtually all concentrator applications because such systems do not produce energy unless oriented closely toward the sun.

Such techniques require pre-assembly and transportation of large frame sections, often to locations that are difficult to access, or they require labor intensive assembly of components on-site, often under unfavorable conditions.
