Flexible laminates for solar modules
View Patent ↗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.
1. A solar module comprising:
a plurality of solar cells arranged in at least two columns, each of the columns having at least two solar cells and including a column reinforcement that is laminated to a first face of each of the solar cells in the column, the column reinforcements of different columns being separated from each other such that a gap is defined between each of the columns;
a first cover layer attached to an outer face of each of the column reinforcements;
a second cover layer attached to a second face of each of the plurality of solar cells; and
flexible conductors located between the first cover layer and the second cover layer, wherein the flexible conductors extend through the gap between the columns of solar cells and electrically connect the solar cells to each other.
2. The solar module according to claim 1 , wherein the columns of solar cells are electrically connected to each other in parallel such that a DC current output by the solar module is proportional to the number of columns of solar cells connected in parallel.
3. The solar module according to claim 1 , wherein the columns of solar cells are electrically connected to each other in series such that an AC voltage output by the solar module is proportional to the number of columns of solar cells connected in series.
4. The solar module according to claim 1 , wherein the column reinforcements are made of a hard plastic material.
5. The solar module according to claim 1 , wherein the column reinforcements are made of glass.
6. The solar module according to claim 1 , wherein the first face of the solar cells comprises a back face of the solar cells.
7. The solar module according to claim 1 , wherein the first face of the solar cells comprises a front face of the solar cells.
8. The solar module according to claim 1 , wherein the flexible conductors comprise ribbon-type conductors or multi-wire conductors.
9. The solar module according to claim 1 , wherein the solar module includes a module interconnection interface for electrically connecting the solar module to another solar module, the module interconnection interface comprising at least two terminal interconnections.
10. The solar module according to claim 1 , wherein the solar module is a frameless module.
11. The solar module according to claim 10 , wherein the first cover layer is a flexible material that continuously covers the outer face of each of the column reinforcements.
12. The solar module according to claim 11 , wherein the second cover layer is a flexible material that continuously covers the second face of each of the plurality of solar cells.
13. The solar module according to claim 12 , wherein the first cover layer, the second cover layer and the gap defined between the columns allows for each of the solar cells to bend or deflect at least 5 degrees with respect to each other.
14. The solar module according to claim 9 , wherein
the solar module is a frameless module, and
the module interconnection interface is disposed between the first cover layer and the second cover layer.
15. The solar module according to claim 10 , further comprising:
one or more openings provided in the first cover layer and the second cover layer for anchoring the solar module to a mounting surface.
16. The solar module according to claim 15 , wherein the one or more openings are provided in a periphery of the first cover layer and the second cover layer in a region that does not overlap with the column reinforcements.
17. The solar module according to claim 10 , further comprising:
one or more openings provided through the first cover layer, the second cover layer and a least one of the column reinforcements for anchoring the solar module to a mounting surface.
