This invention relates an apparatus and method for pre-assembly of certain components of a solar canopy.
Solar energy is a clean, renewal energy source. Photo-electro voltaic cell technology is increasing rapidly and makes installation of solar collector panels housing the photo-electro voltaic cells more and more economically feasible. Beyond the photo-electro voltaic cell technology itself are the problems of placement and support of the solar collector panels. Large numbers of solar collector panels must be assembled in series to achieve useful power production. In remote areas these may be placed on the ground without interfering with land use. In more developed areas, it is desirable to place the solar collector panels such that the land may also be used for other purposes, e.g., for parking lots, school/office hallways, playgrounds, or sports fields. To achieve this requires an elevated structure to support the solar collector panels.
In prior known systems, installation costs amount to around 25% of the overall cost of a solar parking shade installation. These installation cost includes the cost to place modules on a rack, wire the modules together and to a combiner box, bolt the modules in place, and place the support structure on a parking shade structure. These costs often amount to almost the actual panel cost themselves due to the lack of ability to achieve assembly efficiency as well as the need in governmental markets to use union labor.
An additional deficiency in known methods/systems for solar canopy installation is that the size of solar modules used is limited to the size module a contractor can physically carry. The installation process is also cumbersome and dangerous due to work on nonstandard sites and at an elevated height.
It is desirable to have a method and system which overcomes the deficiencies of known systems. The instant invention provides such a solution.
The invention in one embodiment includes a process for aligning two solar panel support channels substantially parallel in a substantially planar pre-assembly tool, wherein the pre-assembly tool has two solar panel support channels guides for receiving and aligning the two solar panel support channels substantially parallel to one another; aligning a plurality of solar panels on top of the two solar panel support channels near opposing edges of each solar panel; and attaching the plurality of solar panels to the two solar panel support channels, thereby forming a solar panel string assembly.
The invention in another embodiment includes a machine for pre-assembly of a solar panel string for a solar canopy, the machine a substantially planar base component, sufficiently long to hold a plurality of solar panels; two substantially parallel solar panel support channels guides attached to a top portion of the base component and extending from one end to an opposing end of the base component, each configured and adapted for receiving and aligning a solar panel support channel; a void in a center portion of the base component between the two support channel guides to provide a working space for electrical connections and components at the bottom of the solar panels.
These and other features and advantages of the present invention will be made more apparent through a consideration of the following detailed description of a preferred embodiment of the invention. In the course of this description, frequent reference will be made to the attached drawings.
Other embodiments of the present invention and its individual components will become readily apparent to those skilled in the art from the foregoing detailed description. As will be realized, the invention is capable of other and different embodiments, and its several details are capable of modifications in various obvious respects, all without departing from the spirit and the scope of the present invention. Accordingly, the drawings and detailed description are to be regarded as illustrative in nature and not as restrictive. It is therefore not intended that the invention be limited except as indicated by the appended claims.
As used in this specification and claims, the “solar panel support channels” comprise “Z”-shaped sheet metal, i.e., “Zee-channels” or “Z-channels”, “C”-shaped sheet metal, i.e., “Cee-channels” or “c-channels”, or standard beams, bars, and other suitable support members.

What has been described above includes example embodiments of the present invention. It is, of course, not possible to describe every conceivable combination of components or methodologies for purposes of describing the present invention, but one of ordinary skill in the art may recognize that many further combinations and permutations of the present invention are possible. Accordingly, the present invention is intended to embrace all such alterations, modifications and variations that fall within the spirit and scope of the appended claims. Furthermore, to the extent that the term “includes” is used in either the detailed description or the claims, such term is intended to be inclusive in a manner similar to the term “comprising” as that term is interpreted as a transitional word in a claim.
