Abstract

Provided are novel building integrable photovoltaic (BIP) modules that are mechanically and electrically interconnectable. According to various embodiments, the modules include channels and protrusion members. A channel of one module snugly fits over a protrusion member of an adjacent module to provide a moisture seal and, in certain embodiments, to collect water in between two modules and direct it downward. In certain embodiments, a channel is configured to interlock with a protrusion member in one or more directions. The channel is positioned along one edge of the module, while the protrusion member is positioned along the opposite edge, so that BIP modules can form a continuous interconnected row. The channel and protrusion member include electrical connectors having conductive elements. Inserting a protrusion member into a channel and, in certain embodiments, sliding one with respect to another also electrically interconnects the conductive elements.

First claim

What is claimed is:

1. A building integrable photovoltaic module comprising:
a photovoltaic insert comprising one or more photovoltaic cells having a front light incident side and a back side, the photovoltaic insert comprising a first edge and a second edge, wherein the first edge is opposite of the second edge;
a channel at the first edge of the photovoltaic insert, the channel having an opening having a width and a length and facing in a downward direction extending from the front light incident side to the back side, wherein the channel is capable of sliding along a length of an adjacent protrusion member of a first adjacent building integrable photovoltaic module while the opening of the channel is physically engaged with the adjacent protrusion member of the first adjacent building integrable photovoltaic module;
a first channel electrical connector positioned within the channel and comprising a first channel conductive element in electrical communication with the one or more photovoltaic cells;
a protrusion member at the second edge of the photovoltaic insert and facing an upward direction, opposite of the downward direction, the protrusion member having a width and a length with first and second ends located at opposing ends of the protrusion member along its length, wherein the length of the protrusion member is capable of sliding along a length of an opening of a channel of a second adjacent building integrable photovoltaic module while physically engaged with the opening of the channel of the second adjacent building integrable photovoltaic module;
a first protrusion electrical connector comprising a first protrusion conductive element in electrical communication with the one or more photovoltaic cells, the first protrusion electrical connector attached to the protrusion member, wherein the first protrusion electrical connector is capable of slidingly engaging a second channel electrical connector positioned within the opening of the channel of the second adjacent building integrable photovoltaic module for making an electrical connection to the second adjacent building integrable photovoltaic module and the first channel electrical connector is capable of slidingly engaging a second protrusion electrical connector positioned at an end of the protrusion member of the first adjacent building integrable photovoltaic module for making an electrical connection to the first adjacent building integrable photovoltaic module,
wherein the first channel conductive element comprises a male conductive element that extends out of the first channel electrical connector in a direction along the length of the channel.

2. The building integrable photovoltaic module of claim 1 , wherein the channel is capable of interlocking with the adjacent protrusion member of the first adjacent building integrable photovoltaic module in an installed position to prevent the channel from sliding with respect to the adjacent protrusion member of the first adjacent building integrable photovoltaic module in the upward direction and/or in a direction parallel to the first edge.

3. The building integrable photovoltaic module of claim 1 , wherein the one or more of the channel and the protrusion member comprises one or more interlocking features.

4. The building integrable photovoltaic module of claim 1 , further comprising a side moisture flap capable of extending under the second adjacent building integrable photovoltaic module.

5. The building integrable photovoltaic module of claim 1 , wherein one or more parts of the channel and/or of the protrusion member are flexible.

6. The building integrable photovoltaic module of claim 1 , wherein the opening of the channel is smaller than a maximum cross-sectional width of the protrusion member.

7. The building integrable photovoltaic module of claim 1 , wherein the first channel electrical connector comprises a second channel conductive element not directly connected to the one or more photovoltaic cells.

8. The building integrable photovoltaic module of claim 1 , wherein the male conductive element is a pin extending out of the first channel electrical connector in a direction along the length of the channel.

9. The building integrable photovoltaic module of claim 1 , wherein the male conductive element comprises a conductive surface along the length of the opening of the channel, and wherein the first protrusion conductive element comprises a conductive surface facing in an outward direction from the end of the protrusion member.

10. The building integrable photovoltaic module of claim 1 , wherein the first protrusion connector is integrated with the protrusion member.

11. The building integrable photovoltaic module of claim 1 , wherein the channel is a part of an overmold formed around the photovoltaic insert.

12. The building integrable photovoltaic module of claim 1 , wherein the first protrusion electrical connector is a female connector.
