Abstract

Provided is a solar cell module having improved weatherability. A frame body has a groove. A module main body is inserted into the groove. An adhesive material is disposed in the groove. The adhesive material is provided at least on a part of a frame body portion excluding frame body corner portions. Through holes communicating with the groove are provided at the corner portions of the frame body.

First claim

The invention claimed is:

1. A solar cell module comprising:
a rectangular plate-shaped module main body including a solar cell, first and second end surfaces parallel to each other, and third and fourth end surfaces parallel to each other;
a frame provided so as to surround the module main body and including a groove into which the module main body is inserted; and
an adhesive member disposed in the groove and bonding the module main body and the frame to each other, wherein
the frame includes:
a first frame section disposed outside the first end surface and including longitudinal end surfaces thereof;
a second frame section disposed outside the second end surface and including longitudinal end surfaces thereof;
a third frame section disposed outside the third end surface and including longitudinal end surfaces on both longitudinal ends of the third frame section, one of the longitudinal end surfaces facing to one of the longitudinal end surfaces of the first frame section, the other of the longitudinal end surfaces facing to one of the longitudinal end surfaces of the second frame section;
a fourth frame section disposed outside the fourth end surface and including longitudinal end surfaces on both longitudinal ends of the fourth frame section, one of the longitudinal end surfaces facing to the other longitudinal end surface of the first frame section, the other of the longitudinal end surfaces facing to the other longitudinal end surface of the second frame section; and
four corner portions at which adjacent two of the first, second, third, and fourth frame sections intersect with each other,

the frame comprises:
a first portion disposed above one principal surface side of the module main body;
a second portion disposed below another principal surface side of the module main body; and
a third portion connecting the first portion and the second portion and constituting the groove with the first and second portions, such that the groove is defined by the first portion, the second portion, and the third portion, and the second portion provided below the groove is formed with a hollow section,

the adhesive member is provided in at least part of a region where the groove is provided except one of the corner portions of the frame and thereby forming a space, where the adhesive member is not provided in the groove, in the one of the corner portions,
the one of the corner portions of the frame includes, at the third portion of the frame, a through hole communicating an exterior of the frame directly with the space in the groove, in such a manner that the through hole comprises a notch opened in a longitudinal end surface of a corresponding one of the frame sections, and
the one of the corner portions of the frame includes, at the first portion of the frame, a removed portion communicating an exterior of the frame directly with the space in the groove, in such a manner that the removed portion comprises a notch opened in the longitudinal end surface of the corresponding one of the frame sections, such that the through hole and the removed portion are provided adjacent to each other.

2. The solar cell module according to claim 1 , wherein
the through hole includes a plurality of through holes respectively provided in the corner portions, and the plurality of through holes are provided in the longitudinal end surfaces of each of the first and second frame sections but are not provided in any of the third and fourth frame sections.

3. The solar cell module according to claim 1 , wherein
the through hole includes a plurality of through holes respectively provided in the corner portions, and the plurality of through holes comprise notches opened in one of the longitudinal end surfaces of each of the frame sections.

4. The solar cell module according to claim 1 , wherein
each of the longitudinal end surfaces of the first frame section is inclined at an angle with respect to the longitudinal direction of the first frame section,
each of the longitudinal end surfaces of the second frame section is inclined at an angle with respect to the longitudinal direction of the second frame section,
each of the longitudinal end surfaces of the third frame section is inclined at an angle with respect to the longitudinal direction of the third frame section, and
each of the longitudinal end surfaces of the fourth frame section is inclined at an angle with respect to the longitudinal direction of the fourth frame section.

5. The solar cell module according to claim 1 , wherein
each of the longitudinal end surfaces of the first frame section is inclined at an angle of approximately 45 degree with respect to the longitudinal direction of the first frame section,
each of the longitudinal end surfaces of the second frame section is inclined at an angle of approximately 45 degree with respect to the longitudinal direction of the second frame section,
each of the longitudinal end surfaces of the third frame section is inclined at an angle of approximately 45 degree with respect to the longitudinal direction of the third frame section, and
each of the longitudinal end surfaces of the fourth frame section is inclined at an angle of approximately 45 degree with respect to the longitudinal direction of the fourth frame section.

6. The solar cell module according to claim 4 , wherein the longitudinal end surfaces of the frame sections facing to each other are in contact with each other.

7. The solar cell module according to claim 1 , wherein
the adhesive member in the groove is not provided between the through hole provided at the third portion and the removed portion at the first portion in the one of corner portions of the frame.

8. The solar cell module according to claim 1 , wherein
the one of the corner portions of the frame includes, at a bottom wall of the hollow section, a second through hole communicating an exterior of the frame directly with a space in the hollow section, in such a manner that the second through hole comprises a notch opened in the longitudinal end surface of the corresponding one of the frame sections.

9. The solar cell module according to claim 1 , wherein
the through hole is provided at each of both longitudinal end surfaces of the first and second frame section, and
the removed portion is provided at each of both longitudinal end surfaces of the first and second frame section.

10. The solar cell module according to claim 8 , wherein
the through hole is provided at each of both longitudinal end surfaces of the first and second frame sections,
the removed portion is provided at each of both longitudinal end portions of the first and second frame sections, and
the second through hole is provided at each of both longitudinal end surfaces of the first and second frame sections.
