Abstract

A solar panel and a solar panel mount system for electrically connecting the solar panel to a solar panel mount upon installation of the solar panel within the solar panel mount. The solar panel can comprise a photovoltaic cell, a support structure in support of the photovoltaic cell, and an auto-connecting electrical contact system comprising a panel electrical contact coupled to the support structure. The solar panel mount system can comprise the solar panel, the solar panel mount, and an auto-connecting electrical contact system operable to electrically connect the solar panel with the solar panel mount. The auto-connecting electrical contact system can include a panel electrical contact coupled to the solar panel and a mount electrical contact coupled to the solar panel mount. The panel electrical contact can be operable to electrically connect with the mount electrical contact upon installing the solar panel within the solar panel mount.

Claims (28)

1. A solar panel comprising:

a photovoltaic cell;

a support structure in support of the photovoltaic cell; and

an auto-connecting electrical contact system comprising a panel electrical contact coupled to the support structure, and operable to electrically connect to a mount electrical contact of a corresponding solar panel mount in an installed position,

wherein the panel electrical contact comprises a plug comprising a housing in support of a plug electrical contact,

wherein the plug further comprises a spring operable with the housing of the plug, the spring being operable to supply a biasing force to bias the plug electrical contact away from the support structure and into electrical connection with a receptacle electrical contact, the biasing force being sufficient to form a seal at an interface between the plug and the receptacle.

2. The solar panel of claim 1 , wherein the housing of the plug comprises a surface configuration having a receptacle interface.

3. The solar panel of claim 1 , wherein the housing of the plug comprises one or more materials configured to deform under an applied load.

4. The solar panel of claim 1 , wherein the housing of the plug comprises an elastic material configured to deform under an applied load and to be biased to return to an undeformed state.

5. The solar panel of claim 1 , wherein the seal is formed at an interface between a housing of the receptacle and the housing of the plug.

6. The solar panel of claim 1 , wherein the plug comprises a spring encapsulated in the housing of the plug, wherein the spring is operable to supply a biasing force to the plug electrical contact, and to the housing of the plug.

7. The solar panel of claim 6 , wherein a portion of the spring is exposed, and comprises the plug electrical contact, such that the spring is in electrical communication with the receptacle electrical contact and an electrically conductive pathway of the solar panel.

8. The solar panel of claim 1 , wherein the panel electrical contact comprises a plug comprising a housing in support of a pair of plug electrical contacts.

9. The solar panel of claim 1 , wherein the panel electrical contact comprises a receptacle comprising a housing in support of a receptacle electrical contact.

10. The solar panel of claim 9 , wherein the housing of the receptacle comprises an opening and an interior cavity formed from a guiding interior surface that facilitates multi-axis alignment between the receptacle and a connecting plug.

11. The solar panel of claim 10 , wherein the guiding interior surface comprises a plug interface.

12. The solar panel of claim 9 , wherein the housing of the receptacle comprises one or more materials configured to deform under an applied load.

13. The solar panel mount of claim 9 , wherein the housing of the receptacle is operable to form a seal with a housing of a connected plug.

14. The solar panel mount of claim 9 , wherein the receptacle comprises an elastic material configured to deform under an applied load and biased to return to an undeformed state.

15. The solar panel of claim 1 , wherein the panel electrical contact comprises a receptacle comprising a housing in support of a pair of receptacle electrical contacts.

16. The solar panel of claim 1 , wherein the auto-connecting electrical contact system further comprises a plurality of panel electrical contacts, including the panel electrical contact, coupled to the support structure.

17. The solar panel of claim 1 , further comprising a conductive pathway electrically connecting the panel electrical contact to the photovoltaic cell of the solar panel.

18. The solar panel of claim 1 , further comprising a seal disposed about the panel electrical contact, the seal being configured to seal the panel electrical contact from an environment upon the panel electrical contact connecting with the mount electrical contact.

19. The solar panel of claim 1 , wherein the panel electrical contact comprises a recess configured to engage with a protrusion.

20. The solar panel of claim 1 , wherein the panel electrical contact comprises a protrusion configured to engage with a recess.

21. The solar panel of claim 1 , wherein the auto-connecting electrical contact system comprises a mounting assembly operable to couple the panel electrical contact to the support structure.

22. A solar panel mount system comprising the solar panel of claim 1 , and a solar panel mount, wherein the solar panel is configured to be supported in an installed position within the solar panel mount.

23. The solar panel mount system of claim 22 , wherein the auto-connecting electrical contact system further comprises the mount electrical contact coupled to the solar panel mount, and wherein the mount electrical contact is electrically connected with the panel electrical contact with the solar panel in the installed position.
