Abstract

A mounting rail for securing photovoltaic (PV) modules to an underlying support structure, such as a torque tube. The mounting rail may include a body and a bracket that is attached to the body and configured to be secured around at least a portion of the support structure.

Claims (31)

1. A mounting rail comprising:

a body including:

a first side wall having a top edge and a bottom edge, the bottom edge defining a first cut-out section;

a first top flange extending from at least a portion of the top edge of the first side wall in a direction that is approximately orthogonal to the first side wall;

a second side wall having a top edge and a bottom edge, the bottom edge defining a second cut-out section;

a second top flange extending from at least a portion of the top edge of the second side wall in a direction that is approximately orthogonal to the second side wall, wherein the first and second top flanges extend in approximately opposite directions; and

a bottom structure connecting at least a portion of the bottom edge of the first side wall with at least a portion of the bottom edge of the second side wall to form a channel having a consistent width that extends an entire length of the body such that the channel is open on opposite ends of the body, the bottom structure having a third cut-out section, wherein the first, second, and third cut-out sections combine to define an aperture that is configured to receive a portion of a support structure; and

a bracket secured to the body that is configured to be secured around at least a portion of the support structure.

2. The mounting rail of claim 1 , wherein the support structure is a torque tube.

3. The mounting rail of claim 1 , wherein:

the first and second top flanges extend an entire length of the first and second side walls; and

from a top down perspective, outside edges of the first and second top flanges are wider at their end sections than at their middle sections.

4. The mounting rail of claim 1 , wherein the bracket is a U-bolt having threaded ends.

5. The mounting rail of claim 4 , wherein the threaded ends of the U-bolt are inserted through holes defined in the bottom structure.

6. The mounting rail of claim 5 , further comprising fasteners configured to secure the U-bolt to the bottom structure.

7. The mounting rail of claim 1 , wherein:

the first top flange includes at least one module mounting hole; and

the second top flange includes at least one module mounting hole.

8. A mounting rail comprising:

a body including:

a first side wall having a top edge and a bottom edge, the bottom edge defining a first cut-out section;

a first top flange extending from at least a portion of the top edge of the first side wall in a direction that is approximately orthogonal to the first side wall, the first top flange having at least one module mounting hole;

a second side wall having a top edge and a bottom edge, the bottom edge defining a second cut-out section;

a second top flange extending from at least a portion of the top edge of the second side wall in a direction that is approximately orthogonal to the second side wall, the second top flange having at least one module mounting hole, wherein the first and second top flanges extend in approximately opposite directions; and

a bottom structure connecting at least a portion of the bottom edge of the first side wall with at least a portion of the bottom edge of the second side wall to form a channel that extends at least a portion of a length of the body, the bottom structure having a first bracket hole, a second bracket hole, a first tab, a second tab, and a third cut-out section, wherein:

the first, second, and third cut-out sections combine to define an aperture that is configured to receive a portion of a support structure,

the first tab includes a third bracket hole and comprises a portion of the bottom structure that is a folded over onto itself so that the first and third bracket holes align, and

the second tab includes a fourth bracket hole and comprises a portion of the bottom structure that is a folded over onto itself so that the second and fourth bracket holes align; and

a bracket configured to be secured to the bottom structure of the body through the first, second, third, and fourth bracket holes, the bracket configured to be secured around at least a portion of the support structure.

9. The mounting rail of claim 8 , wherein the first and second tabs are square or rectangular in shape.

10. The mounting rail of claim 8 , wherein the first and second tabs each have three cut sides with fourth sides attached to the bottom structure.
