Abstract

A bonding clamp includes a top bracket including opposing side walls defining a channel therebetween. The top bracket has an aperture through a central portion thereof. The top bracket is shaped to receive a first photovoltaic (“PV”) module on a first side and a second PV module on a second side. A bottom bracket includes a body and a pair of top flanges extending vertically from a top surface of the body. The pair of top flanges are spaced apart from each other. The bottom bracket also includes anti-rotation flanges extending from a bottom surface of body. A fastening mechanism fastens the top bracket in a fixed position with respect to the bottom bracket.

First claim

What is claimed is:

1. A bonding clamp comprising:
a top bracket including opposing sidewalls defining a channel therebetween, the top bracket having an aperture through a central portion thereof, and the top bracket being shaped to receive a first photovoltaic (“PV”) module on a first side and a second PV module on a second side;
a bottom bracket including:
a body,
a pair of top flanges extending vertically from a top surface of the body, the pair of top flanges being spaced apart from each other equidistantly as the opposing sidewalls of the top bracket to align therewith, and
anti-rotation flanges extending from a bottom surface of body; and

a fastener to fasten the top bracket in a fixed position with respect to the bottom bracket, the fastener having a head shaped and sized to fit between the anti-rotation flanges such that the anti-rotation flanges prevent the fastener from rotation.

2. The bonding clamp according to claim 1 , wherein the fastener includes threading such that a vertical distance between the top bracket and the bottom bracket is adjustable.

3. The bonding clamp according to claim 1 , wherein the fastener extends through the aperture in the top bracket and into the bottom bracket.

4. The bonding clamp according to claim 1 , wherein the sidewalls of the top bracket each include an outwardly extending flange.

5. The bonding clamp according to claim 4 , wherein the outwardly extending flanges of the top bracket extend orthogonally to the respective sidewalls.

6. The bonding clamp according to claim 1 , wherein the bottom bracket further includes a pair of oppositely extending lateral support landings that extend laterally from the body.

7. The bonding clamp according to claim 6 , wherein a height of vertical extension of the pair of top flanges of the bottom bracket is less than a length of horizontal extension of the pair of lateral support landings, respectively.

8. A bonding clamp comprising:
a top bracket including opposing sidewalls defining a channel therebetween, the top bracket having an aperture through a central portion thereof, and the top bracket being shaped to receive a first photovoltaic (“PV”) module on a first side and a second PV module on a second side; and
a bottom bracket having an aperture therethrough, the bottom bracket including:
a body from which extend on opposite sides a pair of support landings,
a pair of top flanges extending vertically from a top surface of the body, the pair of top flanges being spaced apart from each other equidistantly as the opposing sidewalls of the top bracket to align therewith, and
anti-rotation flanges extending from a bottom surface of body,

wherein the aperture of the top bracket and the aperture of the bottom bracket are equally sized to accept a fastener therethrough, and
wherein the fastener has a head shaped and sized to fit between the anti-rotation flanges such that the anti-rotation flanges prevent the fastener from rotation.

9. The bonding clamp according to claim 8 , further comprising the fastener, wherein the fastener is configured to fasten the top bracket in a fixed position with respect to the bottom bracket.

10. The bonding clamp according to claim 8 , further comprising the fastener, wherein the fastener is configured to extend through the bottom bracket and through the top bracket whereat a distal end of the fastener is secured to the top bracket via a nut.

11. The bonding clamp according to claim 8 , wherein the top bracket is configured to be positioned in varying heights above the bottom bracket to accommodate varying thicknesses of PV modules to be secured therebetween.

12. The bonding clamp according to claim 8 , wherein the sidewalls of the top bracket each include an outwardly extending flange.

13. The bonding clamp according to claim 12 , wherein the outwardly extending flanges of the top bracket extend orthogonally to the respective sidewalls.

14. The bonding clamp according to claim 12 , wherein the outwardly extending flanges extend in a direction parallel to a direction of extension of the support landings.

15. A bonding clamp comprising:
a top bracket including:
a central portion,
opposing sidewalls extending from the central portion and defining a channel therebetween,
an aperture through the central portion thereof, and
a pair of outwardly extending flanges that extend transversely from the opposing sidewalls; and

a bottom bracket including:
a body from which extend on opposite sides a pair of support landings,
a pair of top flanges extending vertically from a top surface of the body, the pair of top flanges being spaced apart from each other equidistantly as the opposing sidewalls of the top bracket to align therewith,
a pair of anti-rotation flanges extending from a bottom surface of body in a direction opposite the pair of top flanges; and
a fastener having a head shaped and sized to fit between the pair of anti-rotation flanges such that the pair of anti-rotation flanges prevent the fastener from rotation.

16. The bonding clamp according to claim 15 , wherein the fastener is a bolt sized to extend through both the top bracket and the bottom bracket.

17. The bonding clamp according to claim 16 , wherein the top bracket further includes a tool channel formed into an inner surface of the opposing sidewalls of the top bracket and shaped to accommodate a tool for tightening a nut onto the bolt within the bonding clamp.

18. The bonding clamp according to claim 15 , wherein the top bracket further includes one or more bonding pins that protrude downwardly from one or both of the outwardly extending flanges of the top bracket.

19. The bonding clamp according to claim 15 , wherein the fastener is further sized to extend through the top bracket and the bottom bracket and maintain a space therebetween.
