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 raised structure comprising an outer perimeter, wherein said mounting plate extends beyond an outer perimeter of said mounting device, and wherein there is an open space directly below where said mounting plate extends beyond said outer perimeter of said mounting device;

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 in at least adjacent relation to oppositely disposed portions on said outer perimeter of said raised structure, with said first and second photovoltaic modules being supported by said mounting plate, and with said first and second photovoltaic modules being spaced from said building surface, wherein said first and second photovoltaic modules are spaced from one another and said clamping member is disposed between said first and second photovoltaic modules, wherein said first photovoltaic module is disposed in a direction of increasing elevation of said building surface relative to said second photovoltaic module, wherein said first photovoltaic module is secured between said first clamping leg of said first mounting assembly and said mounting plate of said first mounting assembly, and wherein said second photovoltaic module is secured between said second clamping leg of said first mounting assembly and said mounting plate of said first mounting assembly.

2. The photovoltaic system of claim 1, wherein said raised structure of said mounting plate is centrally disposed relative to an outer perimeter of said mounting plate.

3. The photovoltaic system of claim 1, wherein said threaded clamp fastener extends through a center of said raised structure.

4. The photovoltaic system of claim 1, wherein said outer perimeter of said raised structure and an outer perimeter of said mounting plate are concentric relative to said threaded clamp fastener.

5. The photovoltaic system of claim 1, wherein said first and second photovoltaic modules abut said oppositely disposed portions on said outer perimeter of said raised structure of said first mounting assembly.

6. The photovoltaic system of claim 1, wherein said raised structure of said first mounting assembly positionally registers each of said first and second photovoltaic modules relative to said first mounting assembly.

7. The photovoltaic system of claim 1, wherein said outer perimeter of said raised structure is circular in a plan view.

8. The photovoltaic system of claim 1, wherein each said mounting device comprises a slot and at least one seam fastener that extends through said mounting device and engages a corresponding standing seam of said building surface that is disposed within said slot.

9. The photovoltaic system of claim 1, wherein each of said mounting plate and said clamping member comprises an un-threaded hole through which said threaded clamp fastener extends.

10. The photovoltaic system of claim 1, wherein said mounting plate of each said mounting assembly is clamped onto its corresponding said mounting device by its corresponding said clamping member.

11. The photovoltaic system of claim 1, wherein said mounting plate of each said mounting assembly is located between its corresponding said mounting device and its corresponding said clamping member.

12. The photovoltaic system of claim 1, wherein said upper surface of said mounting plate of each said mounting assembly has a surface area of at least about 5 in.².
