Solar battery module installation structure and dwelling

Filed:2021-04-02Pub:2025-01-14
Applicant:SEKISUI HOUSE, LTD.

The present invention provides a solar cell module installation structure and a house that can reduce manufacturing cost and have good workability as compared with the related art. A support member includes a rail part that extends substantially in a vertical direction and is longer than a length of the solar cell module. The solar cell module includes: a solar cell panel; and a frame member. The solar cell panel includes: a main body panel; a terminal box provided on a back surface of the main body panel; and a wiring part extending from the terminal box. The frame member includes: a holding recess; and a mounting part. The holding recess sandwiches a part of the main body panel and is in contact with a light receiving surface and the back surface of the main body panel. The mounting part is provided on a back surface of the main body panel and is attached to the rail part of the support member. The mounting part has a penetration part that passes through from an inside to an outside with reference to the terminal box when the light receiving surface is viewed from front. The wiring part passes through the penetration part.

Solar cell module installation structure, house, and solar cell module

Filed:2021-04-02Pub:2024-11-19
Applicant:SEKISUI HOUSE, LTD.

The present invention provides a solar cell module installation structure that can be installed on a wall surface of a building, and provides a house and a solar cell module. A support member has a support surface that spreads out substantially in a vertical direction. A locking piece of the support member has: a locking part that faces the support surface at an interval and extends upward; and a connection part that connect the locking part and the support surface. A frame member of the solar cell module has: a holding recess that sandwiches a part of a main body panel of the solar cell module and is in contact with a light receiving surface and a back surface of the main body panel; and a mounting part that is provided on a back surface side of the main body panel, has higher rigidity than the main body panel, has a length longer than or equal to ½ of one side of the main body panel, and extends in the vertical direction. A mounting-side engagement part of the mounting part is a notch that is provided in a lower end part and has a depth extending upward in the vertical direction. The support member is configured to support the solar cell module such that the locking part is inserted in the mounting-side engagement part and such that the solar cell module can be inclined with an inclination angle more than or equal to 10 degrees with respect to the support surface.
