Abstract

A solar power system can include a rail and a solar module disposed on the rail. A clamp assembly can couple the solar module to the rail. The clamp assembly can have a clamped configuration in which the solar module is secured to the rail and an unclamped configuration. The clamp assembly can comprise an upper clamp member, a lower clamp member coupled to the rail, and a stabilization member mechanically engaging the upper clamp member and the lower clamp member. The stabilization member can prevent rotation of the lower clamp member relative to the rail when the clamp assembly is in the clamped and unclamped configurations. In the unclamped configuration, the stabilization member can be biased such that the upper clamp member is disposed at a sufficient clearance above the rail to permit the insertion of the solar module between the upper clamp member and the rail.

First claim

What is claimed is:

1. A solar module clamp assembly having a major axis, the solar module clamp assembly comprising:
an upper clamp member;
a lower clamp member;
a fastener extending along the major axis and coupling the upper clamp member with the lower clamp member; and
a stabilization member positioned between the upper clamp member and the lower clamp member, the stabilization member being configured to support the upper clamp member at a position vertically spaced above the lower clamp member, the stabilization member having a relaxed state and one or more compressed states,
wherein the stabilization member in the relaxed state prevents translation of the upper clamp member towards the lower clamp member along the major axis,
wherein the stabilization member in the one or more compressed states is compressed such that the upper clamp member is translated towards the lower clamp member along the major axis relative to the relaxed state,
wherein the upper clamp member has a first arm and a second arm extending in opposite directions perpendicular to the major axis, the first arm being adapted to secure a first solar module to a mounting structure and the second arm being adapted to secure a second solar module to the mounting structure, and
wherein the stabilization member includes a central portion, a first upwardly-extending flange, a second upwardly-extending flange, a first downwardly-extending flange, and a second downwardly-extending flange.

2. The clamp assembly of claim 1 , wherein the lower clamp member is positioned between the first downwardly-extending flange and the second downwardly-extending flange.

3. The clamp assembly of claim 1 , wherein the first upwardly-extending flange and the second upwardly-extending flange directly contact the upper clamp member.

4. The clamp assembly of claim 1 , wherein the central portion of the stabilization member includes an opening and the fastener extends through the opening of the central portion.

5. The clamp assembly of claim 1 , wherein the fastener is a threaded fastener and the threaded fastener threadably couples the upper clamp member with the lower clamp member.

6. The clamp assembly of claim 1 , wherein the fastener passes through the upper clamp member to couple with the lower clamp member.

7. The clamp assembly of claim 1 , wherein the first arm captures an edge portion of the first solar module and the second arm captures an edge portion of the second solar module such that the first and second solar modules are secured between the first and second arms and the mounting structure.

8. A solar power system, comprising:
a mounting structure;
a first solar module disposed on the mounting structure;
a second solar module disposed on the mounting structure adjacent to the first solar module;
solar module clamp assembly having a major axis, the solar module clamp assembly comprising:
an upper clamp member;
a lower clamp member;
a fastener extending along the major axis and coupling the upper clamp member with the lower clamp member; and
a stabilization member positioned between the upper clamp member and the lower clamp member, the stabilization member being configured to support the upper clamp member at a position vertically spaced above the lower clamp member, the stabilization member having a relaxed state and one or more compressed states,

wherein the stabilization member in the relaxed state prevents translation of the upper clamp member towards the lower clamp member along the major axis,
wherein the stabilization member in the one or more compressed states is compressed such that the upper clamp member is translated towards the lower clamp member along the major axis relative to the relaxed state,
wherein the upper clamp member has a first arm and a second arm extending in opposite directions perpendicular to the major axis, the first arm secures the first solar module to a mounting structure and the second arm secures the second solar module to the mounting structure, and
wherein the stabilization member includes a central portion, a first upwardly-extending flange, a second upwardly-extending flange, a first downwardly-extending flange, and a second downwardly-extending flange.

9. The solar power system of claim 8 , wherein the lower clamp member is positioned between the first downwardly-extending flange and the second downwardly-extending flange.

10. The solar power system of claim 8 , wherein the first upwardly-extending flange and the second upwardly-extending flange directly contact the upper clamp member.

11. The solar power system of claim 8 , wherein the central portion of the stabilization member includes an opening and the fastener extends through the opening of the central portion.

12. The solar power system of claim 8 , wherein the fastener is a threaded fastener and the threaded fastener threadably couples the upper clamp member with the lower clamp member.

13. The solar power system of claim 8 , wherein the fastener passes through the upper clamp member to couple with the lower clamp member.

14. The solar power system of claim 8 , wherein the first arm captures an edge portion of the first solar module and the second arm captures an edge portion of the second solar module such that the first and second solar modules are secured between the first and second alias and the mounting structure.

15. The clamp assembly of claim 1 , wherein the first upwardly-extending flange and the second upwardly-extending flange each include a first end attached to the central portion and a second end that is positioned higher than the first end when the stabilization member is in the relaxed state.

16. The clamp assembly of claim 1 , wherein the first downwardly-extending flange and the second downwardly-extending flange each include a first end attached to the central portion and a second end that is positioned lower than the first end when the stabilization member is in the relaxed state.

17. The solar power system of claim 8 , wherein the first upwardly-extending flange and the second upwardly-extending flange each include a first end attached to the central portion and a second end that is positioned higher than the first end when the stabilization member is in the relaxed state.

18. The solar power system of claim 8 , wherein the first downwardly-extending flange and the second downwardly-extending flange each include a first end attached to the central portion and a second end that is positioned lower than the first end when the stabilization member is in the relaxed state.
