Abstract

A rail-based solar panel mounting system including at least one mounting bracket coupled to a mounting surface and at least one elongated rail having an open channel configuration, wherein the at least one elongated rail is coupled to the at least one mounting bracket. The mounting system also includes at least one mid-clamp assembly couplable to the at least one elongated rail, wherein the at least one mid-clamp assembly is configured to retain at least one solar panel relative to the at least one elongated rail.

First claim

What is claimed is:

1. A hidden end clamp assembly configured to secure a frame member of a solar panel module to a rail, the assembly comprising:
a clamping body, wherein the clamping body comprises a top clamping portion having a lower clamping surface and a leg portion extending downwardly from the lower clamping surface at an acute angle, wherein a distal end portion of the leg portion comprises a base portion having at least one elongated opening formed therethrough;
a nut member, wherein the nut member comprises a pair of flanges extending from a rear portion, wherein the pair of flanges are spaced apart so as to at least partially receive the base portion of clamping body, wherein the rear portion extends at an angle substantially equal to the acute angle of the leg portion of the clamping body, and further wherein the rear portion comprises a threaded opening formed therethrough; and
a fastener member, wherein the fastener member comprises a drive head and a threaded shank, and wherein the threaded shank is configured to extend through the at least one elongated opening of the base portion and engage with the threaded opening of the rear portion of the nut member such that tightening of the fastener member causes the clamping body to move downward relative to the nut member.

2. The assembly of claim 1 , wherein the top clamping portion further comprises one or more bonding portions extending from the lower clamping surface, wherein the bonding portions are formed of an electrically conducting material.

3. The assembly of claim 2 , wherein the one or more bonding portions comprise one or more sharp piercing points.

4. The assembly of claim 1 , wherein the base portion of the clamping body comprises a pair of elongated openings formed therethrough.

5. The assembly of claim 1 , further comprising a retaining member configured to be coupled to the clamping body and the nut member by the fastener member to support the clamping body relative to the nut member when the fastener member is in an untightened state.

6. The assembly of claim 5 , wherein the retaining member comprises a bottom retaining portion, a front extension, a rear extension, and a curved portion coupling the front extension and the rear extension, wherein the rear extension is configured to extend within the rear portion of the nut member such that the retaining member acts as a spring to urge the rear portion of the nut member away from the leg portion of the clamping body.

7. The assembly of claim 6 , wherein the front extension comprises a front through-hole and the rear extension comprises a rear through-hole, wherein the front through-hole and the rear-through hole are sized and configured to receive the threaded shank of the fastener member therethrough so as to couple the retaining member to the clamping body and the nut member.

8. The assembly of claim 1 , wherein the base portion of the clamping body further comprises a pair of projecting side surfaces having respective sloping ledges and the flanges of the nut member comprise respective sloping flange bottom surfaces, further wherein the sloping flange bottom surfaces engage the sloping ledges when the fastening member is tightened.

9. The assembly of claim 1 , wherein the pair of flanges of the nut member further comprise respective wing projections angled outwardly therefrom, wherein the wing projections are configured to provide a slidable interface between the nut member and a pair of elongated recesses of the rail.

10. The assembly of claim 9 , wherein each wing projection comprises at least one piercing projection extend from an upper portion of a notch.

11. The assembly of claim 1 , wherein the base portion of the clamping body further comprises a front face, wherein a surface plane of the front face is parallel to the angled leg portion of the clamping body.

12. The assembly of claim 1 , wherein a rear surface of the top clamping portion of the clamping body comprises a plurality of parallel ribs to form a textured surface.

13. The assembly of claim 1 , wherein the base portion of the clamping body further comprises a barb connector.

14. The assembly of claim 13 , further comprising a tether, wherein the tether is configured to be coupled to the barb connector.

15. The assembly of claim 14 , wherein the tether comprises a pulling end portion, an elongated central portion, and a coupling end portion, wherein the coupling end portion comprises an opening sized and configured to surround the barb connector.

16. The assembly of claim 1 , wherein each of the clamp body, the nut member, and the fastener member are formed of an electrically conducting material.

17. A hidden end clamp assembly configured to secure a frame member of a solar panel module to a rail, the assembly comprising:
a clamping body, wherein the clamping body comprises a top clamping portion having a lower clamping surface and a leg portion extending downwardly from the lower clamping surface at an acute angle, wherein a distal end portion of the leg portion comprises a base portion having at least one elongated opening formed therethrough;
a nut member, wherein the nut member comprises a pair of flanges extending from a rear portion, wherein the pair of flanges are spaced apart so as to at least partially receive the base portion of clamping body, wherein the rear portion extends at an angle substantially parallel to the leg portion of the clamping body, and further wherein the rear portion comprises a threaded opening formed therethrough; and
a fastener member, comprises a drive head and a threaded shank, the threaded shank through the at least one elongated opening of the base portion wherein a longitudinal axis of the threaded shank is nonparallel to the rail, and engage with the threaded opening of the rear portion of the nut member such that tightening of the fastener member causes the clamping body to move downward relative to the nut member.

18. The assembly of claim 17 , a retaining member positioned at least partially between the clamping body and the nut member and configured to support the clamping body relative to the nut member wherein the retaining member comprises a bottom retaining portion, a front extension, a rear extension, and a curved portion coupling the front extension and the rear extension, wherein the rear extension is configured to extend within the rear portion of the nut member such that the retaining member acts as a spring to urge the rear portion of the nut member away from the leg portion of the clamping body.

19. The assembly of claim 17 , wherein the clamping body comprises a barb connector extending from a surface thereof; and a tether, wherein the tether is configured to be couplable to the barb connector of the base portion of the clamping body to allow the assembly to be selectively positioned along the rail such that the lower clamping portion of the clamping body extends at least partially over the frame member of the solar panel module.

20. The assembly of claim 19 , wherein the longitudinal axis of the threaded shank extends in a direction through the rail.
