Abstract

A mounting assembly (70c) for installing solar cell or photovoltaic modules (58) on a building surface (34) is disclosed. The mounting assembly (70c) includes a mounting device (74), a stud (114) that may be threaded to the mounting device (74), a clamping member (142) that may be positioned on the stud (114), and a nut (128) that may be threaded onto the stud (114) to secure the clamping member (142) to the mounting device (74). A mounting plate (110′) is disposed somewhere between the clamping member (142) and the mounting device (74). This mounting plate (110′) includes a raised structure or dome (174) on its upper surface (170) for positionally registering modules (58) thereto, a plurality of grounding projections (172) on this same upper surface (170), and a plurality of wiring tabs or clips (178) on its lower surface (176).

Claims

1. A photovoltaic system, comprising:

a building surface;

a plurality of mounting assemblies comprising a first mounting assembly, wherein each said mounting assembly comprises;

a mounting device mounted to said building surface;

a mounting plate positioned on said mounting device, wherein an upper surface of said mounting plate comprises a plurality of grounding projections;

a clamping member comprising first and second clamping legs; and

a threaded clamp fastener that extends through said clamping member, through said mounting plate, and that is secured to said mounting device; and

first and second photovoltaic modules positioned on said upper surface of said mounting plate of said first mounting assembly, wherein said first clamping leg of said first mounting assembly is engaged with said first photovoltaic module, wherein said second clamping leg of said first mounting assembly is engaged with said second photovoltaic module, wherein at least one of said plurality of grounding projections of said first mounting assembly is engaged with said first photovoltaic module, and wherein at least one of said plurality of grounding projections of said first mounting assembly is engaged with said second photovoltaic module.

2. The photovoltaic system of claim 1, wherein said plurality of grounding projections are spaced about said threaded clamp fastener.

3. The photovoltaic system of claim 1, wherein said plurality of grounding projections are equally spaced about said threaded clamp fastener.

4. The photovoltaic system of claim 1, wherein each of said plurality of grounding projections is integrally formed with said mounting plate.

5. The photovoltaic system of claim 1, wherein said mounting plate further comprises a lower surface that is disposed oppositely of said upper surface, wherein said lower surface of said mounting plate comprises at least one wiring clip.

6. The photovoltaic system of claim 5, wherein said lower surface of said mounting plate comprises a plurality of wiring clips.

7. The photovoltaic system of claim 6, wherein said plurality of wiring clips are equally spaced about said threaded clamp fastener.

8. The photovoltaic system of claim 5, wherein each said wiring clip is integrally formed with said mounting plate.

9. The photovoltaic system of claim 5, wherein each said wiring clip comprises a recessed region.

10. The photovoltaic system of claim 5, wherein said mounting plate further comprises an aperture associated with each said wiring clip, wherein said aperture provides access to a space below said mounting plate.

11. The photovoltaic system of claim 5, wherein said upper surface of said mounting plate comprises first and second PV module positional registrants.

12. The photovoltaic system of claim 11, wherein said upper surface of said mounting plate comprises a raised structure, wherein first and second portions on an outer perimeter of said raised structure comprises said first and second PV module positional registrants, respectively.

13. The photovoltaic system of claim 12, wherein said raised structure of said mounting plate is centrally disposed relative to an outer perimeter of said mounting plate.

14. The photovoltaic system of claim 12, wherein said threaded clamp fastener extends through a center of said raised structure.
