Bracket for connection of a junction box to photovoltaic panels
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.

at least one adjustable spacer adapted to be mounted and adjustable in position in a space between the junction box and the photovoltaic panel.
2. The device of claim 1 , wherein the junction box is adapted to attach to a non-photovoltaic side of the photovoltaic panel and the plate is adapted to attach to a photovoltaic side of the photovoltaic panel.
3. The device of claim 1 , wherein the at least one adjustable spacer is spring loaded.
4. The device of claim 1 , wherein the at least one adjustable spacer is rotatable around the central fastener.
5. The device of claim 1 , further comprising: at least one fixed spacer adapted to be fixed in position in the space between the junction box and the photovoltaic panel.
6. The device of claim 1 , further comprising one or more connectors adapted to receive electrical power generated by the photovoltaic panel.
7. The device of claim 1 , wherein the central fastener is further adapted to attach the device to a second photovoltaic panel by clamping the second photovoltaic panel between the junction box and the plate.
8. The device of claim 7 , wherein the central fastener is adapted to extend between an edge of the photovoltaic panel and an adjacent edge of the second photovoltaic panel.
9. The device of claim 7 , further comprising one or more connectors mounted on the junction box and adapted to electrically connect the photovoltaic panel to the second photovoltaic panel.
10. The device of claim 1 , wherein the central fastener is further adapted to attach the device to second, third, and fourth photovoltaic panels by clamping the second, the third, and the fourth photovoltaic panels between the junction box and the plate.
11. The device of claim 1 , wherein the plate is rotatably connected to the central fastener.
12. The device of claim 1 , further comprising a direct-current-to-direct-current converter or a direct-current-to-alternating-current converter within the junction box.
13. The device of claim 1 , further comprising a bracket connecting the junction box to the central fastener.
14. A method comprising:
mounting a junction box to a photovoltaic panel by clamping the photovoltaic panel between a side of the junction box and a plate connected to the junction box by a central fastener; and
mounting a spacer adjustable in position in a space between the junction box and the photovoltaic panel.
