DESCRIPTION OF THE SPECIFIC EMBODIMENTS

(11) According to the present application, techniques related generally to an attachment assembly for solar panels are provided. More specifically, embodiments of the present invention provide an attachment assembly for framing solar modules.

(12) FIG. 1 is a simplified perspective view of a frame assembly (including indications for x-y-z directions) for a plurality of solar modules according to an embodiment of the present invention. As shown, the frame assembly includes a pair of frame rail assemblies coupled together using an attachment member, which interlocks each of the frame rail assemblies together with the module frames. Additionally, the frame rail assemblies include a pair of openings for a U-bolt and clamp or other member to couple the rail assembly to a pipe or other member of a tracker or solar system. Of course, there can be other variations.

(13) FIG. 2 is a more detailed view along the x-y direction for the frame assembly including attachment member according to an embodiment of the present invention. In an example as shown is a direct normal view in plane of a module glass. In an example, as shown in a center region is a cam. The cam can either work for two modules, or just one if construction tolerance is needed for spacing the modules along the torque tube. Of course, there can be other variations. Further details of the present assembly can be found throughout the present specification and more particularly below.

(14) FIG. 3 is a more detailed view of an x-z direction or top view for the frame assembly according to an embodiment of the present invention. As shown, the frame assembly includes a pair of frames each of which is configured on an edge of a solar module. The assembly also includes a pair of rails sandwiched between the frames. An attachment member, which is configured between the rails holds the frame assembly together, as shown.

(15) FIG. 4 is an exposed perspective view of the frame assembly (including indications for x-y-z direction) where one of the solar modules has been removed according to an embodiment of the present invention. In an example, one of the modules has been removed. In an example, an extruded panel rail bracket is shown, which is configured to a module frame. The cam configured to the panel rail is also shown. In an example, the cam can either fasten to one rail or both rails. In an example, the rail mounts to a U-bolt and U-bolt clamp, which are configured through the rail along a direction normal to the direction of the length of the rail. In an example, the cam will serve as an electrical bonding path, as well as a mechanical lock to prevent the bracket from sliding out of the module groove. In an example, the U-bolt clamp will be secured to a support member (or pipe type member) of a tracker.

(16) FIG. 5 is an exposed side view of the frame assembly where one of the solar modules has been removed according to an embodiment of the present invention. As shown, the exposed side view is configured as a site for a second solar module to couple to the pair of rail structures, which can be separate units or integrated together, depending upon the embodiment.

(17) In an example, the system has an attachment member (e.g., member with cam structure for interlocking or other attachment configuration). The attachment member comprises a first end region having a first spatial configuration and a second end region having a second spatial configuration. The attachment member comprises a length provided between the first end region and the second end region. The first end region is configured to integrate the first spatial region configuration with the first groove region by intimately coupling the first spatial region with the first groove region by initiating the intimate coupling along a first spatial direction relative to the first groove region. In an example, the second end region is configured to intimately couple to the second groove region by initiating the intimate coupling along a second spatial direction that is different from the first spatial direction, while the initiating of the initiating of the intimate coupling in the second spatial direction occurs while the first spatial region is firmly engaged with the first groove.

(18) In an example, the first spatial configuration comprises a first locking device, which has a locking structure configured to operably couple to the first groove structure in a locking position rather than an unlocked position. In an example, the second spatial configuration comprises a second locking device configured to operably couple to the second groove structure in a locking position rather than an unlocked position. In an example only, the attachment member can be similar or the same as those provided by Zep Solar, Inc., although there can be others manufacturers.

(19) In an example, the first groove region comprises a first recessed region disposed between a first pair of elevated regions. In an example, the second groove region comprises a second recessed region between a second pair of elevated regions.

(20) In an example, the first frame structure is configured around a periphery of the first solar module. In an example, the second frame structure is configured around a periphery of the second solar module.

(21) In an example, the first groove region is similar in shape and size as the second groove region.

(22) In an example, the first frame structure and the second frame structure comprise, respectively, a first rail structure and a second rail structure coupled together using the attachment member.

(23) In an example, the first rail structure and the second rail structure comprising a pair of openings to operably couple a U-bolt and clamp assembly to be configured to a support member.

(24) In an example, the support member is provided on a tracker system.

(25) In an example, the U-bolt and claim assembly comprises a pair of extension members, each of the extension members having an opening, the opening being configured to allow an attachment device to be inserted there through to couple a portion of each of the first frame structure and second frame structure together. Further details of the attachment member is described throughout the present specification and more particular below.

(26) FIG. 6 is a simplified diagram of an attachment member and illustration of coupling the attachment member to a solar module frame according to an embodiment of the present invention. As shown is the attachment member in an example, using a tongue and key side. The attachment member is operably coupled to a rail member, which is provided for an assembly. The attachment member and rail are operably couple to a first solar module, which is then configured to a second solar module, as described.

(27) FIG. 7 is perspective view of clamping assembly according to an alternative embodiment of the present invention. As shown, the U-bolt and clamp assembly comprises a pair of extension members integrated with the U-bolt and clamp assembly. Each of the extension members having an opening disposed within the extension member. The opening is configured to allow an attachment device to be inserted there through to couple a portion of each of the first frame structure and second frame structure together such that the clamp assembly, pair of rails, and frames form a sandwich structure.

(28) FIG. 8 is a side view of the clamping assembly according to the alternative embodiment.

(29) FIGS. 9 and 10 illustrate, respectively, a perspective view and a top-view of a clamp according to the alternative embodiment.

(30) It is understood that the examples and embodiments described herein are for illustrative purposes only and that various modifications or changes in light thereof will be suggested to persons skilled in the art and are to be included within the spirit and purview of this application and scope of the appended claims. In an example, each of the elements can be made of a suitable material such as metal, stainless steel, iron, aluminum, or alloys thereof, among others, which are sufficiently rigid and weather proof.
