Abstract

The invention relates to a photovoltaic insulating glazing comprising a multi-layer glazing with a photovoltaic module. The glazing is further characterized in that two contact strips for contacting the photovoltaic module are led out from an intermediate space between the glass layers and a spacer spaces the glass layers apart, thereby forming the intermediate space.

Claims

1-12. -12. (cancelled)

13. A photovoltaic insulating multi-layer glazing, for connection to an electrical element disposed external to the glazing, the glazing comprising:

a photovoltaic module;

a glass pane;

a spacer disposed between said photovoltaic module and said glass pane to define a space between said photovoltaic module and said glass pane, said spacer having an opening only on an outer side thereof;

a contact strip in electrical communication with said photovoltaic module and fed out of said photovoltaic module to contact the external electrical element; and

a bolt cooperating with said contact strip, said opening and the connecting element to fix the contact strip in said opening from an outside direction.

14. The photovoltaic insulating glazing of claim 13, wherein said spacer comprises several spacer elements and several connecting elements, wherein individual spacer elements are connected via said connecting elements and said opening is provided in at least one of said connecting elements.

15. The photovoltaic insulating glazing of claim 13, further comprising an elastic sealing nipple disposed in said opening for sealing said space between said module and said glass pane from an outside of the glazing.

16. The photovoltaic insulating glazing of claim 15, wherein said elastic sealing nipple comprises a threaded nut.

17. The photovoltaic insulating glazing of claim 14, wherein at least one connecting element consists essentially of plastic material.

18. The photovoltaic insulating glazing of claim 14, wherein said spacer elements are pushed onto said connecting elements and are clamped thereon.

19. The photovoltaic insulating glazing of claim 14, wherein said connecting elements are linear connecting elements.

20. The photovoltaic insulating glazing of claim 14, wherein said connecting elements are corner connecting elements.

21. The photovoltaic insulating glazing of preceding claim 14, further comprising at least one cable lug for connection to at least one of the electrical element and said contact strip.

22. The photovoltaic insulating glazing of claim 14, wherein said spacer elements comprise electrically conducting, shaped elements.

23. The photovoltaic insulating glazing of claim 13, further comprising at least one non-conducting washer disposed to prevent electric contact between said bolt and said spacer.

24. The photovoltaic insulating glazing of claim 13, wherein said opening has a stepped bore.

25. The photovoltaic insulating of claim 13, wherein said opening has a thread and said bolt is a threaded bolt which is screwed into said opening thread.

26. The photovoltaic insulating glazing of claim 13, wherein said the bolt is a blind rivet.
