Abstract

Discussed are solar panel systems as well as devices and methods for mounting the solar panel systems to roofs and building structures. Catch clamp, mid clamp, and optionally end clamp assemblies can be preinstalled to the solar panels at the job site before placing and securing the resulting solar panel assemblies to the building structure such as a roof. After an installer places and secures a first solar panel assembly to the building structure, they can install each subsequent solar panel assemblies by attaching the leading edge of the subsequent solar panel assembly to the trailing edge of the previous solar panel assembly using a catch and catch receiver, hook and slot, tab and slot, or similar mechanism.

Claims (35)

1. A method of securing a solar panel array to a building structure, comprising:

pre-attaching a first solar panel clamp assembly to a first leading edge of a first solar panel frame, the first solar panel frame surrounding a first solar panel, and pre-attaching a second solar panel clamp assembly to a first trailing edge of the first solar panel frame, resulting in a first solar panel assembly;

pre-attaching a catch clamp assembly to a second leading edge of a second solar panel frame, the second solar panel frame surrounding a second solar panel, and pre-attaching a third solar panel clamp assembly to a second trailing edge of the second solar panel frame, resulting in a second solar panel assembly;

securing the first solar panel assembly to the building structure by securing the first solar panel clamp assembly and the second solar panel clamp assembly to the building structure; and

pivoting and securing the second solar panel assembly to the first solar panel assembly and pivoting the second solar panel assembly with respect to the building structure including pivoting the catch clamp assembly against the second solar panel clamp assembly.

2. The method of claim 1 , wherein:

the securing of the first solar panel assembly to the building structure by the securing of the first solar panel clamp assembly and the second solar panel clamp assembly to the building structure is carried out without positionally adjusting the first solar panel clamp assembly and the second solar panel clamp assembly lengthwise or widthwise with respect to the first solar panel.

3. The method of claim 1 , further comprising:

placing the first solar panel face down at a job site that includes the building structure before the pre-attaching of the first solar panel clamp assembly and the second solar panel clamp assembly to the first solar panel; and

turning the first solar panel assembly face up before the securing of the first solar panel clamp assembly and the second solar panel clamp assembly to the building structure.

4. The method of claim 3 , further comprising:

placing the second solar panel face down at the job site before the pre-attaching of the catch clamp assembly and the third solar panel clamp assembly to the second solar panel; and

turning the second solar panel assembly face up before securing the third solar panel clamp assembly to the building structure.

5. The method of claim 1 , wherein:

the pivoting and securing of the second solar panel assembly to the first solar panel assembly and the pivoting of the second solar panel assembly with respect to the building structure includes pivoting a hook arm of the catch clamp assembly against a panel hook platform extending from the second solar panel clamp assembly.

6. The method of claim 1 , wherein:

the pivoting and securing of the second solar panel assembly to the first solar panel assembly and the pivoting of the second solar panel assembly with respect to the building structure includes rotating and securing a hook arm of the catch clamp assembly against a panel hook platform of the second solar panel clamp assembly and engaging a hook receiver of the second solar panel clamp assembly with the hook arm.

7. The method of claim 1 , wherein:

the pivoting and securing of the second solar panel assembly to the first solar panel assembly and the pivoting of the second solar panel assembly with respect to the building structure includes rotating and securing a hook arm of the catch clamp assembly against a panel hook platform of the second solar panel clamp assembly and engaging a hook receiver of the second solar panel clamp assembly with an open end of the hook arm.

8. A method of securing a solar panel array to a building structure, comprising:

pre-attaching a first solar panel clamp assembly directly to a first leading edge of a first solar panel frame, the first solar panel frame surrounds a first solar panel and pre-attaching a second solar panel clamp assembly directly to a first trailing edge of the first solar panel frame, resulting in a first solar panel assembly;

securing the first solar panel assembly to the building structure by securing the first solar panel clamp assembly and the second solar panel clamp assembly to the building structure;

pre-attaching a catch clamp assembly directly to a second leading edge of a second solar panel frame, the second solar panel frame surrounds a second solar panel, and pre-attaching a third solar panel clamp assembly to a second trailing edge of the second solar panel frame, resulting in a second solar panel assembly; and

pivoting and securing the second solar panel assembly to the first solar panel assembly and pivoting the second solar panel assembly with respect to the building structure includes pivoting the catch clamp assembly against the second solar panel clamp assembly.

9. The method of claim 8 , wherein:

the pivoting and securing of the second solar panel assembly to the first solar panel assembly and the pivoting of the second solar panel assembly with respect to the building structure includes pivoting a hook arm of the catch clamp assembly against a panel hook platform extending from the second solar panel clamp assembly.

10. The method of claim 8 , wherein:

the pivoting and securing of the second solar panel assembly to the first solar panel assembly and the pivoting of the second solar panel assembly with respect to the building structure includes rotating and securing a hook arm of the catch clamp assembly against a panel hook platform of the second solar panel clamp assembly and engaging a hook receiver of the second solar panel clamp assembly with the hook arm.

11. The method of claim 8 , wherein:

the pivoting and securing of the second solar panel assembly to the first solar panel assembly and the pivoting of the second solar panel assembly with respect to the building structure includes rotating and securing a hook arm of the catch clamp assembly against a panel hook platform of the second solar panel clamp assembly and engaging a hook receiver of the second solar panel clamp assembly with an open end of the hook arm.

12. A method of securing a solar panel array to a building structure, comprising:

pre-attaching a first solar panel clamp assembly directly to a leading edge of a first solar panel frame and pre-attaching a second solar panel clamp assembly directly to a trailing edge of the first solar panel frame, resulting in a first solar panel assembly that is rail-less;

securing the first solar panel assembly to the building structure by securing the first solar panel clamp assembly and the second solar panel clamp assembly directly to the building structure;

pre-attaching a catch clamp assembly directly to a second leading edge of a second solar panel frame of a second solar panel and pre-attaching a third solar panel clamp assembly directly to a second trailing edge of the second solar panel frame, resulting in a second solar panel assembly that is rail-less; and

rotationally engaging a hook arm of the catch clamp assembly with a panel hook platform of a hook receiver of the second solar panel clamp assembly and securing the catch clamp assembly to the second solar panel clamp assembly, before securing the third solar panel clamp assembly directly to the building structure.
