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, connectable 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 connectable to the bracket.

Claims

1. An apparatus, comprising:

a junction box including a direct-current-to-direct-current converter or a direct-current-to-alternating-current converter;

a fastener configured to extend between at least two photovoltaic panels;

a bracket connected to the fastener, wherein the bracket is configured to attach to the junction box, wherein the junction box is configured to electrically connect the at least two photovoltaic panels; and

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

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 at least one of 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, wherein the junction box is configured to attach to a non-photovoltaic side of a photovoltaic panel of at least one of the at least two photovoltaic panels.

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

6. A device comprising:

a first junction box;

a bracket configured to attach to (1) the first junction box and (2) a first photovoltaic panel or a second photovoltaic panel; and

a central fastener attached to said bracket,

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

7. The device of claim 6, wherein the bracket is further configured to attach to a third photovoltaic panel and a fourth photovoltaic panel.

8. The device of claim 7, wherein the central fastener and bracket are further configured to clamp the third photovoltaic panel and the fourth photovoltaic panel between the bracket and the central fastener.

9. The device of claim 6, wherein the bracket comprises mounting holes configured to attach of the bracket to the first junction box.

10. The device of claim 6, wherein, the first junction box is attached to the first photovoltaic panel on a side thereof and the second photovoltaic panel has a second junction box attached to a side thereof.

11. The device of claim 10, wherein the second junction box is operably connected to the first junction box.

12. The device of claim 6, wherein the first junction box includes a direct-current-to-direct-current converter or a direct-current-to-alternating-current converter.

13. A method comprising mounting a first junction box to at least one of at least two photovoltaic panels by clamping at least one of the at least two photovoltaic panels between the first junction box and a fastener extending between front or back sides of the at least one of the at least two photovoltaic panels.

14. The method of claim 13, further comprising mounting a spacer between the first junction box and at least one of the at least two photovoltaic panels.

15. The method of claim 13, wherein the at least two photovoltaic panels include a first photovoltaic panel and a second photovoltaic panel, and wherein the method further comprises connecting the first junction box to the first photovoltaic panel and connecting a second junction box to the second photovoltaic panel.

16. The method of claim 15, further comprising connecting the first junction box to the second junction box.

17. The method of claim 15, further comprising:

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

18. The method of claim 15, further comprising electrically connecting the first junction box to the first photovoltaic panel and to the second photovoltaic panel.

19. The method of claim 13, wherein the at least two adjacent photovoltaic panels are electrically connected within the first junction box.
