Abstract

A device for attaching a junction box to a photovoltaic. The photovoltaic panel has a photovoltaic side and a non-photovoltaic side. The device includes a bracket with a first side attachable to the junction box and a second side attachable to the non-photovoltaic surface of the photovoltaic panel. A central fastener is attachable at one end to the bracket and a plate is adapted for connecting to the other end of the central fastener and for mounting on the photovoltaic side of the photovoltaic panel. One or more rotatable spacers, connectible to the central fastener, may be located on the non-photovoltaic side of the photovoltaic panel. One or more fixed spacers may be located on the non-photovoltaic side connectible to the bracket.

Claims

1. An apparatus, comprising:

a fastener having a first end and a second end, wherein the fastener is configured to extend between at least two photovoltaic panels each comprising a first side and a second side, the first end of the fastener is disposed on the first sides of the at least two photovoltaic panels, and the second end of the fastener is disposed on the second sides of the at least two photovoltaic panels;

a bracket connected to the first end of the fastener, wherein the bracket is configured to enable attachment to the bracket of a junction box configured to service the at least two photovoltaic panels; and

wherein the fastener and the bracket, are configured to clamp the at least two photovoltaic panels to the bracket.

2. The apparatus of claim 1, further comprising an adjustable spacer configured to be mounted and adjustable in position in a space between the junction box and the at least two photovoltaic panels.

3. The apparatus of claim 2, wherein the adjustable spacer is rotatable around the fastener.

4. The apparatus of claim 1, further comprising the junction box, wherein the junction box includes a direct-current-to-direct-current converter or a direct-current-to-alternating-current converter.

5. The apparatus of claim 4, wherein the junction box is adapted to attach to a non-photovoltaic side of a photovoltaic panel of the at least two photovoltaic panels.

6. The apparatus of claim 1, further comprising a plate connected to the second end of the fastener.

7. A device comprising:

a central junction box;

a bracket including a first side and a second side, the first side adapted to attach to a side of the central junction box and the second side positioned opposite the first side and adapted to attach to a side of a first photovoltaic panel and a side of a second photovoltaic panel; and

a central fastener having first and second ends, the first end attached to said bracket,

wherein the central fastener and bracket are adapted to suspend the bracket and the central junction box from the first photovoltaic panel and the second photovoltaic panel by clamping the first photovoltaic panel and the second photovoltaic panel between the second side of the bracket and the central fastener.

8. The device of claim 7, wherein the second side of the bracket is further adapted to attach to a side of a third photovoltaic panel and a side of a fourth photovoltaic panel.

9. The device of claim 8, wherein the central fastener and bracket are further adapted to clamp the third photovoltaic panel and the fourth photovoltaic panel between the second side of the bracket and the central fastener.

10. The device of claim 7, wherein the bracket comprises mounting holes configured to enable attachment of the bracket to the central junction box.

11. The device of claim 7, wherein, the first photovoltaic panel has a first junction box attached to a side thereof and the second photovoltaic panel has a second junction box attached to a side thereof.

12. The device of claim 11, wherein the first junction box and the second junction box are operably connected to the central junction box.

13. The device of claim 7, wherein the central junction box includes a direct-current-to-direct-current converter or a direct-current-to-alternating-current converter.

14. A method comprising:

mounting a central junction box to at least two adjacent photovoltaic panels by clamping the at least two adjacent photovoltaic panels between a side of the central junction box and a fastener connected to the central junction box, the fastener extending between corners or sides of the at least two adjacent photovoltaic panels.

15. The method of claim 14, further comprising mounting a spacer adjustable in position in a space between the central junction box and the at least two adjacent photovoltaic panels.

16. The method of claim 14, wherein the at least two adjacent photovoltaic panels include a first photovoltaic panel and a second photovoltaic panel, and wherein the method further comprises connecting a first junction box to the first photovoltaic panel and connecting a second junction box to the second photovoltaic panel.

17. The method of claim 16, further comprising connecting the first junction box and the second junction box to the central junction box.

18. The method of claim 16, further comprising:

mounting the first junction box to the first photovoltaic panel by clamping the first photovoltaic panel between a side of the first junction box and a first fastener; and

mounting the second junction box to the second photovoltaic panel by clamping the second photovoltaic panel between a side of the second junction box and a second fastener.

19. The method of claim 16, further comprising electrically connecting the central junction box to the first photovoltaic panel and to the second photovoltaic panel.

20. The method of claim 14, wherein the at least two adjacent photovoltaic panels are electrically connected within the central junction box.
