Solar panel clamp system
In one embodiment the present invention includes a solar panel clamp system for mounting solar panels on ground-level and raised purlins. Such systems include left-handed and right-hand clamps that can be attached to opposite sides of solar panel assemblies that include mounting frames. Left-handed clamps can attach to the mounting frame of a solar panel and include surfaces that can rest on the top surfaces of purlins and include a lip or shelf surface onto which the right-handed clamps of a mounting frame of a neighboring solar panel can rest to increase the speed and safety of installing solar panels on raised purlins. Through holes in the left-handed and right-handed clamps can then be used as guide holes for drilling into the purlins. The majority of, if not all of, the solar panel installation using the clamps of the present invention can be completed from underneath the raised purlins.
1. A solar panel clamp assembly comprising:
a left-handed clamp comprising:
a lower structural arm;
an upper structural arm, having a clamping structure, and coupled to a first side of the lower structural arm at a first angle; and
a lip surface coupled to a second side of the lower structural arm at a second angle; and
a right-handed clamp comprising:
a lower structural arm;
an upper structural arm, having a clamping structure, and coupled to a first side of the lower structural arm at a first angle;
wherein a second side of the lower structural arm of the right-handed clamp is dimensioned to fit against the second side of the left-handed clamp; and
wherein a first end of the right-handed clamp is seated on the lip surface and a first surface of the clamping structure of the left-handed clamp matches up with a first surface of the clamping structure of the right-handed clamp, and
wherein the upper structural arm is configured to rest on a top surface of a purlin, and wherein the first side of the lower structural arm is configured to fit against a side surface of the purlin.
2. A method for installing solar panels on a plurality of purlins comprising:
forming a plurality of solar panel mounting assemblies comprising:
attaching multiple left-handed clamps to a first side of each of a plurality of solar panel mounting frames, wherein the left-handed clamps each comprise:
a lower structural arm;
an upper structural arm, having a clamping structure, and coupled to a first side of the lower structural arm at a first angle; and
a lip surface coupled to a second side of the lower structural arm at a second angle;
attaching multiple right-handed clamps to a second side each of a plurality of solar panel mounting frames, wherein the right-handed clamps each comprise
a right-handed clamp comprising:
a lower structural arm;
an upper structural arm, having a clamping structure, and coupled to a first side of the lower structural arm at a first angle;
wherein a second side of the lower structural arm of the right-handed clamp is dimensioned to fit against the second side of the left-handed clamp; and
wherein a first end of the right-handed clamp is dimensioned to fit on the lip surface and a first surface of the clamping structure of the left-handed clamp matches up with a first surface of the clamping structure of the right-handed clamp, further comprising disposing a first solar panel mounting assembly on a first purlin and a second purlin,
wherein disposing the first solar panel mounting assembly comprises:
disposing the first side of the first solar panel mounting assembly having the left-handed clamps on a top surface of the second purlin; and
holding the second side of the first solar panel mounting assembly having the right-handed clamps in a position in alignment with the first purlin.
3. The method of claim 2 drilling holes in the first purlin using through holes in the multiple right-handed clamps as guides and fastening the first solar panel mounting assembly to the first purlin using fasteners, the through holes and the drilled holes.
4. The method of claim 3 further comprising disposing a second solar panel mounting assembly on the second purlin and a third purlin;
wherein disposing the second solar panel mounting assembly comprises:
disposing the right-handed clamps of the second solar panel mounting assembly on the lip surfaces of the left-handed clamps of the first solar panel mounting assembly; and
disposing the left-handed clamps of the second solar panel mounting assembly on a top surface of the third purlin.
5. The method of claim 4 wherein disposing the second solar panel mounting assembly on the second purlin and the third purlin further comprises drilling holes in the second purlin by using through holes in the multiple left-handed clamps of the first solar panel mounting assembly and through holes in the multiple right-handed clamps of second solar panel mounting assembly.
6. The method of claim 5 further comprising fastening the first solar panel mounting assembly and the second solar panel mounting assembly to the second purlin using the through holes in the left-handed clamps of the first solar panel mounting assembly, the through holes in the right-handed clamps of the second solar panel mounting assembly, and the drilled holes in the second purlin.
7. The method of claim 6 wherein the drilled holes in the first and second purlins are disposed in vertical surfaces of the first and second purlins.
8. The method of claim 7 wherein the first and second purlin comprise raised beams disposed on a plurality of posts.
9. The method of claim 8 wherein the disposing the first solar panel mounting assembly on the first and second purlins and disposing the second solar panel mounting assembly on the second and third purlins are performed from a position below the raised beams.
