Solar battery module

Abstract

A solar battery cell having a hexagonal shape is divided into four at a straight line connecting between opposed apexes and a straight line connecting between middle points of opposed sides. Two of the divided cells are arranged without being turned upside down such that oblique sides thereof oppose each other; thus, a substantially rectangular-shaped unit is configured. In adjoining two units, an interconnector is routed from a front surface of one of the units to a back surface of the other unit. Thus, the two units are electrically connected to each other through the interconnector. Hence, it is unnecessary to route an interconnector from a front surface of one divided cell to a back surface of another divided cell at a portion where oblique sides of the divided cells oppose each other; therefore, it is unnecessary to secure a large clearance at the portion.

Claims

1. A solar battery module comprising: a plurality of tetragonal-shaped solar battery cells forming a substantially rectangular contour in pairs such that oblique sides of two solar battery cells oppose each other, whereinthe plurality of solar battery cells are arranged on a plane in a state that oblique sides of two solar battery cells oppose each other, and the solar battery cells having the oblique sides opposing each other are connected in parallel through an interconnector.

2. The solar battery module according to claim 1, comprising: a plurality of units each forming the substantially rectangular contour by combining two solar battery cells such that the oblique sides thereof oppose each other, whereinthe plurality of units are arranged in a matrix such that longer sides of the substantially rectangular contours thereof oppose each other and shorter sides of the substantially rectangular contours thereof oppose each other.

3. The solar battery module according to claim 2, wherein in the plurality of units, a front surface of one of adjoining two units is electrically connected to a back surface of the other unit in accordance with a predetermined electrical connection pattern in sequence.

4. The solar battery module according to claim 3, wherein in a portion where shorter sides of the adjoining two units oppose each other, the interconnector is routed from a front surface of one of the units to a back surface of the other unit for electrical connection between the front surface and the back surface.

5. The solar battery module according to claim 1, comprising: a plurality of blocks each forming the substantially rectangular contour by combining two solar battery cells such that the oblique sides thereof oppose each other, whereinthe plurality of blocks are arranged such that shorter sides of the substantially rectangular contours thereof oppose each other to configure a plurality of units each having a substantially rectangular contour slenderer than the substantially rectangular contour of the block, andthe plurality of units are arranged in a matrix such that longer sides of the substantially rectangular contours thereof oppose each other and shorter sides of the substantially rectangular contours thereof oppose each other.

6. The solar battery module according to claim 5, wherein in the plurality of units, a front surface of one of adjoining two units is electrically connected to a back surface of the other unit in accordance with a predetermined electrical connection pattern in sequence.

7. The solar battery module according to claim 6, wherein in a portion where shorter sides of the adjoining two units oppose each other, the interconnector is routed from a front surface of one of the units to a back surface of the other unit for electrical connection between the front surface and the back surface.

8. The solar battery module according to any one of claims 1 to 7, wherein the solar battery cells placed on the solar battery module are identical in type to one another, and are arranged on a plane such that identical polarities thereof are directed to a single direction.

9. A solar battery module comprising: a unit including a plurality of tetragonal-shaped solar battery cells forming a substantially rectangular contour in pairs such that oblique sides thereof oppose each other; andan interconnector for electrically connecting between the solar battery cells in the unit, whereinthe unit is formed into a square shape by the plurality of solar battery cells, andthe interconnector connects between the solar battery cells configuring the unit without being routed from a front surface of one of the solar battery cells to a back surface of the other solar battery cell and vice versa at a portion where the oblique sides of the solar battery cells oppose each other.

10. The solar battery module according to claim 9, wherein the plurality of solar battery cells configuring the unit are electrically connected in parallel.
