Solar panel frame clamps mounting a solar panel frame to a purlin
Solar panel frame clamps are disclosed. The clamps can include a clamp body for coupling together a mounting rail of a solar panel frame and a purlin. The clamp body may be c-shaped with ends of the clamp body defining an opening for receiving objects to be clamped. The ends of the clamp body may be provided with threaded apertures for receiving a set screw and a set screw bolt. Tightening the set screw bolt can pull the clamp body towards the objects to be clamped. The set screw, or another suitable feature, may contact the clamped object to facilitate electrical continuity throughout a system incorporating the solar panel frame clamps.
1. A solar panel system, comprising:
a solar panel frame comprising a mounting rail;
a purlin; and
a frame clamp, comprising:
a clamp body comprising a first end and a second end defining an opening therebetween;
a threaded aperture extending through the first end in communication with the opening;
a continuity element extending from the second end into the opening; and
a bolt extending through the threaded aperture into the opening opposing the continuity element, wherein the continuity element comprises a set screw that extends into the opening and contacts the mounting rail before the second end contacts the mounting rail when the bolt is tightened.
2. The solar panel system of claim 1 , further comprising a second frame clamp that clamps a second flange of the mounting rail to the purlin.
3. The solar panel system of claim 1 , wherein:
the bolt perpendicularly engages the purlin; and
the continuity element perpendicularly engages a flange of the mounting rail.
4. The solar panel system of claim 3 , wherein the bolt and the continuity element facilitate electrical continuity between the mounting rail and the purlin through the clamp body.
5. The solar panel system of claim 1 , wherein the clamp body defines a void within the frame clamp and adjacent to the opening.
6. The solar panel system of claim 5 , wherein at least one of the purlin and the mounting rail comprises an extending member disposed within the void.
7. The solar panel system of claim 1 , wherein tightening the bolt causes the bolt to engage the purlin and pulls the second end against the mounting rail to clamp the mounting rail to the purlin.
8. The solar panel system of claim 1 , wherein:
the first end comprises a first arm projecting in a first direction, the first direction extending perpendicularly to the threaded aperture and obliquely from a contiguously formed portion of the first end; and
a second arm projects from the second end in a second direction, the second direction extending parallel to a direction of extension of the continuity element.
9. The solar panel system of claim 1 , wherein the first end and the second end comprise parallel flat surfaces that face each other.
10. The solar panel system of claim 1 , wherein the first end and the second end taper towards each other.
11. The solar panel system of claim 1 , wherein the clamp body comprises one of aluminum and stainless steel.
