Abstract

A solar cell module is configured from a solar cell panel, and a frame structural body. The frame structural body is provided with: a plurality of frame members which are provided to peripheral edges of the solar cell panel, and which have a cross-sectional shape having a hollow portion; corner members which are provided in the hollow portions; holding sections which are provided in the hollow portions, and which hold the corner members; and a plurality of formed rivet sections which apply pressure to the frame members.

First claim

The invention claimed is:

1. A solar cell module, comprising:
a solar cell panel;
a plurality of frame members that are provided at the peripheral edge of the solar cell panel and that have a cross-sectional shape having a hollow portion;
a corner member provided in the hollow portion;
a holding section that is provided in the hollow portion and that holds the corner member; and
a plurality of rivet sections formed by pressing the frame member.

2. The solar cell module according to claim 1 , wherein: the plurality of rivet sections are provided on an inner wall of the frame member.

3. The solar cell module according to claim 2 , wherein: the plurality of rivet sections are configured so that a dent is formed in the inner wall of the frame member superposed with the corner member.

4. The solar cell module according to claim 2 , wherein: the plurality of rivet sections are provided in the inner wall of the frame member superposed with the holding section of the frame member and the corner member.

5. The solar cell module according to any one of claims 1 to 4 , wherein: the corner member is smaller than an insertion section surrounded by the holding section.

6. A production method of a solar cell module comprising:
preparing a plurality of frame members having a cross-sectional shape having a hollow portion and inserting L-shaped corner members to the hollow portions of the two frame members;
simultaneously pressing inner walls of the two frame members superposed on the corner member to form rivet sections in the two frame members, respectively; and
integrating the two frame members to forma corner portion; and using the plurality of frame members to form a frame of the solar cell panel.
