Abstract

A solar module includes a laminate structure having at least two solar cells. Each of the solar cells has an individual reinforcement laminated to one face of each of the solar cells. The solar cells are spaced apart from each other and the individual reinforcements are spaced apart from each other such that a gap is defined between each of the solar cells. The solar module includes flexible conductors that extend through the gap between the solar cells and electrically connect the solar cells to each other.

First claim

What is claimed is:

1. A solar module comprising:
a first cover layer;
a second cover layer;
an active layer including a plurality of solar cells disposed between the first cover layer and the second cover layer, wherein a first gap is defined between each of the plurality of solar cells;
a reinforcement on a first face of each of the plurality of solar cells, wherein the reinforcement includes a plurality of separate reinforcement layers attached to the first face of each of the plurality of solar cells, wherein a second gap is defined between edges of each of the plurality of separate reinforcement layers; and
a plurality of flexible connectors located between the first cover layer and the second cover layer, wherein the flexible connectors extend through the first gap between each of the plurality of solar cells to electrically connect the solar cells to one another,
wherein the plurality of separate reinforcement layers include reinforcement layers that each reinforce a subset of at least two solar cells of the plurality of solar cells, wherein one of the plurality of separate reinforcement layers corresponding to that subset bridges the first gap between the at least two solar cells.

2. The solar module of claim 1 further comprising:
a module interconnection interface configured to electrically connect the solar module to another solar module.

3. The solar module of claim 2 , wherein
the module interconnection interface includes at least two terminal interconnections.

4. The solar module of claim 2 , wherein
the module interconnection interface is disposed between the first cover layer and the second cover layer.

5. The solar module of claim 1 , wherein
the flexible connectors comprise ribbon-type conductors or multi-wire conductors.

6. The solar module of claim 1 further comprising:
at least one of a DC/AC microinverter, a DC/DC converter and a DC/DC optimizer disposed between the first cover layer and the second cover layer.

7. The solar module of claim 1 , further comprising:
at least one of a DC/AC microinverter, a DC/DC converter and a DC/DC optimizer secured to an outer face of one of the first cover layer and the second cover layer.

8. The solar module of claim 1 , wherein
reinforcement is made of glass or a hard plastic material.

9. The solar module of claim 1 , wherein
the first gap between each of the plurality of solar cells includes a filler material configured to limit flexing of the flexible connectors in the first gap.

10. The solar module of claim 1 , wherein
the solar module is a frameless module; and,
the first cover layer and the second cover layer include anchor points at a peripheral region located outside of the plurality of solar cells;
wherein the anchor points of the peripheral region are secured to a mounting surface using a fastener, an adhesive or a combination thereof.

11. The solar module of claim 1 , further comprising:
one or more openings provided in the first cover layer and the second cover layer for receiving fasteners to secure the solar module to a mounting surface.

12. The solar module of claim 1 , wherein
the first cover layer is a flexible material that continuously covers an outer face of the reinforcement.

13. The solar module of claim 12 , wherein
the second cover layer is a flexible material that continuously covers a second face of each of the plurality of solar cells.

14. The solar module of claim 1 , further comprising:
an attachment structure configured to mechanically attach the solar module to another solar module.

15. The solar module of claim 14 , wherein the attachment structure includes a plurality of latches configured to mechanically attach the solar module to the another solar module to form an array of solar modules.

16. A solar module comprising:
a laminate structure including
a first flexible cover layer;
a second flexible cover layer;
a plurality of solar cells disposed between the first cover layer and the second cover layer, wherein a first gap is defined between each of the plurality of solar cells;
a rigid reinforcement layer on one or more of the plurality of solar cells, wherein the rigid reinforcement layer includes a plurality of separate reinforcement layers attached to a first face of each of the one or more of the plurality of solar cells, wherein a second gap is defined between edges of each of the plurality of separate reinforcement layers,
wherein the plurality of separate reinforcement layers include reinforcement layers that each reinforce a subset of at least two solar cells of the plurality of solar cells, wherein one of the plurality of separate reinforcement layers corresponding to that subset bridges the first gap between the at least two solar cells;
a plurality of flexible connectors located between the first flexible cover layer and the second flexible cover layer, wherein the flexible connectors extend through the first gap between each of the plurality of solar cells and electrically connect the solar cells to one another; and

a module interconnection interface integrated into the laminate structure between the first and second flexible cover layers, the module interconnection interface being configured to electrically connect each of the plurality of laminate structures to another of the plurality of laminate structures.

17. The solar module according to claim 16 , further comprising at least one of a DC/AC microinverter, a DC/DC converter and a DC/DC optimizer.
