DETAILED DESCRIPTION OF THE INVENTION
[0035] In the following description, and for the purposes of explanation, numerous specific details are provided to thoroughly understand the various aspects of the invention. It will be understood, however, by those skilled in the relevant arts, that the present invention may be practiced without these specific details. In other instances, known structures and devices are shown or discussed more generally in order to avoid obscuring the invention. In many cases, a description of the operation is sufficient to enable one to implement the various forms of the invention, particularly when the operation is to be implemented in software. It should be noted that there are many different and alternative configurations, devices and technologies to which the disclosed embodiments may be applied. The full scope of the invention is not limited to the example(s) that are described below.
[0036] FIG. 6 illustrates an exemplary junction box mount comprising a bracket 200 for use with a rail-less solar panel array system. The bracket 200 as generally L-shaped and includes a front side 210 and a rear side 237. The front side 210 includes several openings or pilot holes 220. Although one pilot hole would be sufficient, having several pilot holes 220 allows a junction box 300, as shown in FIG. 8, to be secured at various locations along the front side 210 of the bracket 200. The junction box 300 can be secured to the front side 210 of the bracket 200 with by using fasteners such as standard screws 290 as shown in FIG. 7, or slots can be used to interconnect the junction box 300 when necessary. The slots can also use self-driven screws. The advantage of a slot is that allows more location freedom. The bracket 200 can be manufactured in any suitable manner such as extruding it into a single piece. The bracket 200 is typically combined with a second identical bracket to properly secure a wide range of junction box sizes in place along a solar panel frame.
[0037] The rear side 237 of the bracket is better shown in FIG. 7. The rear side 237 in this exemplary embodiment illustrates a single-sized clip 235 that is adapted for a single-sized solar panel frame 500. The clip 235 includes a bottom panel 280, a rear panel 230, and a top panel 240. The bottom panel includes an opening 285. The opening 285 is typically threaded for receiving a fastener such as an adjustable screw 260, which in this embodiment is a standard thumb screw 260, with a threaded shank 270. The top panel includes at least one grip 250 and may also include a raised portion 255 that can penetrate a surface oxidation layer of a metal object. The thumb screw 260 is used to tighten the grip to the solar panel frame 500 as shown in FIG. 9. The thumb screw 260 also serves to electrically bond the bracket 200 to the solar panel frame 500 by penetrating the surface oxidation layer of the solar panel frame 500 when tightened. It is understood that other types of fasteners can be used to secure the clip 235 to the solar panel frame 500 that can penetrate a surface oxidation layer of a metal object. Also pictured is an example of a self-tapping screw 290 in the exploded view of the end of the bracket 200 that shows how the junction box 300 is secured to the bracket 200.
[0038] A typical junction box 300 is installed as shown using the following steps. First, the junction box is secured to the brackets 200 as shown in FIG. 8. The exemplary junction box 300 has a side mount 310 on each side of the box 300 with screw holes 315. The screws 290 are secured through the screw holes 315 and into at least one of the pilot holes 220 on the front side 210 of the bracket 200. It is understood by one of ordinary skill in the art that the junction box 300 can be secured to the brackets 200 by using similar fasteners to the screws 290 or by permanently affixing the junction box 300 with adhesive methods.
[0039] Once the junction box 300 is secured to the brackets 200, the brackets 200 are coupled to the solar panel frame 500 as shown in FIG. 9. A typical solar panel frame 500 has a top side 540, a front side 520 and a bottom side 530. The clip 235 is inserted over the solar panel frame 500 so that the top panel 240 of the clip 235 contacts the top side 540 of the solar panel. Likewise, the rear panel 230 of the clip 235 contacts the front side 520 of the solar panel frame 500, and finally the bottom panel 280 of the clip 235 contacts the bottom side 530 of the solar panel frame 500.
[0040] Once the clip 235 is in place, the brackets 200 are then secured onto the solar panel frame 500 as shown below in FIG. 10. This is accomplished by turning the thumb screw 260 until the clip 235 is secured to the solar panel frame 500 and the threaded shank 270 penetrates the surface oxidation layer of the solar panel frame 500, which creates an electrical conducting path between the junction mount 200 and the solar panel frame 500. When the brackets 200 are installed, typically, enough clearance should be provided so that the top of the junction box 300 can be lifted at a 90-degree angle with respect to the solar panel frame 500.
[0041] FIGS. 11 and 12 illustrate an alternate exemplary embodiment showing the bracket 400. The bracket 400 includes an adjustable mounting clip 435 that allows the bracket 400 to be secured to solar panel frames with varying-sized edges. The clip 435 includes an adjustable portion 430 that comprises a top panel 440, a rear panel 465, and a fastener such as an adjustment screw 442 that includes a threaded shank 445. The clip 435 includes a bottom panel 480. The adjustable portion 430 includes an aperture 462 that may be threaded for receiving the threaded shank 445. The top of the bracket 447 also includes an aperture 448 that is typically threaded for receiving the threaded shank 445. The clip 435 is secured to the solar panel frame by way of adjustment screw 442 as shown and it is understood that other types of fasteners can be used to secure the clip 435. The adjustable clip 435 also includes a grounding pin 450 on the bottom surface of the top panel for penetrating the surface oxidation layer of the top side 540 of the solar panel frame 500 when the adjustment screw 442 is tightened downward. This enables the bracket 400 to create an electrical connecting path between the junction box 300 and the solar panel frame 500. An exploded view of one of the pilot holes is also shown in FIG. 12.
[0042] The bracket 400 is installed in a similar fashion as the first embodiment of the bracket 200. First, the junction box 300 is installed onto the brackets as shown in FIG. 13 such that the side mount 310 is secured to the front side 410 of the bracket 400 by tightening the screws 290 to the openings or pilot holes 420. Again, it is understood by one of ordinary skill in the art that the junction box 300 can be secured to the brackets 400 by using similar fasteners to the screws 290 or by permanently affixing the junction box 300 with adhesive methods. The clips 435 are then coupled to the solar panel frame 500 as shown in FIG. 14. The clip 435 is inserted over the solar panel frame 500 so that the top panel 440 of the clip 435 contacts the top side 540 of the solar panel. Likewise, the rear panel 430 of the clip 435 contacts the front side 520 of the solar panel frame 500, and finally the bottom panel 480 of the clip 435 contacts the bottom side 530 of the solar panel frame 500.
[0043] Finally, once the clip 435 is in place the brackets 400 are then secured on to the panel 500 as shown in FIGS. 15 and 16. The adjustment screw 442 is then tightened so that the adjustable portion 430 is then lowered and pressed downward onto the top side 540 of the solar panel frame as shown below in FIG. 16. Once tightened, the grounding pin 450 penetrates the surface oxidation layer of the top side 540 of the solar panel frame 500 and creates an electrical grounding path between the junction box 300 and the solar panel frame 500. When the bracket 400 is installed, typically, enough clearance should be provided so that the top of the junction box 300 can be lifted at a 90-degree angle with respect to the solar panel frame 500.
