Leak Resistant Solar Panel Installation Clamp and Method of Use

Abstract

A solar panel mounting assembly having a rail having two opposing edges. An I-beam having a foot and a head separated by a spine is positioned such that the foot is within the rail and the head is outside of the channel. A gap is positioned between the head of the I-beam and the edges of the rail. One or more bolts is utilized that extends through the base of the rail and through the foot of the I-beam such that tightening the bolts causes the gap between the head of the I-beam and the edges of the rail to reduce in size. This causes the I-beam to tighten on a solar panel held in the gap, thus securing the I-beam in place.

DETAILED DESCRIPTION

[0016] A leak resistant solar panel assembly can be used to securely mount solar panels while minimizing leakage of fluid between the solar panels and the assembly hardware. FIG. 1 is a cross-section of the solar panel assembly with a mounted solar panel. As shown in FIG. 1, the assembly 10 includes a rail 12 with a base 14 and two walls 16a, 16b. The base 14 has a first side 15, a second side 17, and holes 19 connecting the first side 15 and the second side 17.

[0017] Each of the walls 16a, 16b has a base edge 20 and a free edge 22. The walls 16a, 16b are attached to the first side 15 of the base 14 at each base edge 20. Each of the walls 16a, 16b extends away from the first side 15 of the base 14 such that the walls 16a, 16b oppose each other to form a channel, with the space between the free edges 22 defining an opening into the channel.

[0018] FIG. 1 also shows an I-beam 30 having a foot 32, a spine 34, and a head 36. The foot 32 and head 36 are each a flat, elongated member, and are positioned parallel to each other and joined by perpendicular attachment of the spine 34. The I-beam is positioned within the rail 12 such that the foot 32 is situated within the channel and the spine 34 extends through the channel opening with the head 36 outside of the channel. The relative position of the head 36 and free edges 22 on either side of the spine 34 defines a gap 40 between the free edges 22 and the head 36. The gap 40 is capable of accommodating the thickness of a solar panel 50. In FIG. 1, a solar panel 50 is inserted into the gap 40.

[0019] Also shown in FIG. 1 is one of a plurality of clamps. In a preferred embodiment each clamp 60 has a pair of retaining flanges 62, a coupler 64, and an adjuster 66. In alternative embodiments, the coupler 64 and the adjuster 66 can link directly to the clamp 60 without the need for a pair of retaining flanges. As shown in FIG. 1, the pair of retaining flanges 62 is positioned inside the channel and configured to clasp the foot 32. The coupler 64 is attached to the pair of retaining flanges 62 and extends through one of the holes 19 in the base 14. The adjuster 66 is attached to the coupler 64 and is located and accessible from the underside of the rail, outside the channel. The clamp 60 is configured such that manipulation of the adjuster 66 changes the distance between the pair of retaining flanges 62 and the adjuster 66.

[0020] When the edge of a solar panel 50 is inserted into the gap 40, the adjuster 66 may be manipulated so as to shorten the distance between the adjuster 66 and the pair of retaining flanges 62, thereby pulling the I-beam 30 further into the channel of the rail 12 and reducing the size of the gap 40 until the solar panel is securely held between a free edge 22 and the head 36.

[0021] Different clamp configurations may be employed. In one embodiment, shown in FIG. 1, the pair of retaining flanges 62 is curved to clasp the foot 32 and contains an aperture near its center. The coupler 64 is a bolt inserted through the pair of retaining flanges aperture and anchored into a lock nut nested in, or optionally integrated into, the pair of retaining flanges 62. The adjuster 66 is an integrated head of the bolt, which is contoured to allow turning of the bolt. By turning the adjuster 66, the bolt turns and, because it is interfaced with the lock nut on the other side of the pair of retaining flanges 62, the pair of retaining flanges 62 is pulled deeper into the channel, bringing the I-beam 30 with it.

[0022] Because the solar panel is secured by tightening the clamp 30 and thereby narrowing the gap 40 between the solar panel 50 and the head 36, pressure is exerted on the edge of the solar panel 50 during installation. Thus, it may be useful to insert a protective layer, such as a foam cushion, rubber, etc., between the free edge 22 and the underside of the head 36. This will help secure the solar panel 50 into the assembly while minimizing the risk of damage to the solar panel 50. Using a leak resistant material, such as rubber, as this protective layer will also minimize leakage between the solar panel 50 and the head 36. Once installed, an additional sealing layer, such as silicone or some similar substance, may be applied to the junction 60 between the solar panel 50 and the head 36 to further minimize any potential invasion by water.

[0023] While FIG. 1 depicts the head 36 and foot 32 as being a roughly the same width, different widths may be used. For example, the foot 32 need be of sufficient width so as to be able to be positioned within the opening of the channel. A relatively wider head 36, however, may be desired to achieve greater contact with the solar panel 50 and a more secure installation.

[0024] FIG. 2 shows an exploded view of the embodiment described above. Sample part dimensions are provided, though other dimensions may be used. FIG. 2 shows the rail 12 and I-beam 34. The parts making up the clamp 60 include the coupler 64 with integrated head 66, and the pair of retaining flanges 62. In the embodiment show, the coupler 64 is anchored into the pair of retaining flanges using a square nut that is set within a recess in the pair of retaining flanges 62 which prevents it from turning.

[0025] FIG. 3 shows another embodiment of the solar panel assembly 10. In this embodiment, a nut with internal threading is pressed into a custom hole in the I-beam 34 and is aligned with a hole drilled into the foot of the I-beam. This nut functions as the pair of retaining flanges 62 and the coupler 64 with integrated adjuster 66 is inserted in to the hole in the I-beam and engages the nut such that the I-beam is drawn into the rail as the adjuster is turned. A detailed view of the construction of the I-beam holes and insertion of the nut is shown in FIGS. 4 and 5, respectively.

[0026] FIG. 6 shows an alternative embodiment of the solar panel assembly 10. In this embodiment there is an indentation and opening at the bottom of the U-bracket/rail base 14. A washer or bolt fits into this opening and has one or more holes to allow for the passage of one or more bolts 94 or screws. The bolts or screws pass through openings 91 in the washer 92, through the holes in the bottom of the U-shaped bracket, and through the foot of the I-beam. Alternatively, the top of the I-beam can be configured to have one or more openings for passage of one or more bolts which pass through the top of the I-beam, the foot of the I-beam, and through the base to the washer, as shown in FIG. 7. The washer or bolt serves to align the connector bolts or screws that pass through the clamp and into the I-beam. The connector bolts can be made to insert on either side of the I-beam, with the I-beam externally threaded 90 as shown in FIG. 6. Alternatively a single bolt can be utilized to pass through the center of the I-beam to connect the I-beam to the U-bracket. Tightening of the connector bolts or screws serves to draw the I-beam toward the bottom of the U-shaped connector, thus tightening the I-beam grip on the solar panels illustrated in each of the figures. Rubber or similar gaskets can be positioned between the I-beam flanges and the solar panel to provide a further weather resistant or weather tight junction.

[0028] FIGS. 10 illustrates a layout of two parallel tracks for securing opposing edges of a solar panel. FIG. 11 illustrates two opposing parallel channels used to clamp opposing edges of a solar panel.

From the foregoing description, it will be apparent that various changes may be made without departing from the spirit and scope of the disclosure as defined herein.
