Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of solar cell modules on building walls faces challenges with complex connections and increased manufacturing costs due to narrow wiring spaces and the need for longer wiring lengths when frames are mounted on the sides, affecting both cost and workability.
Innovation Solution
A solar cell module installation structure featuring a support member with a rail part extending vertically, allowing the wiring to pass through a penetration part, which reduces wiring length and simplifies connections, and separate frame members for easier maintenance and reduced production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the height from the wall surface to the light receiving surface is lowered to achieve design excellence, then the aesthetic unity is improved, but the wiring space is extremely narrowed
Solution Approach 1:
The patent utilizes the depth dimension (distance from wall surface) to resolve the contradiction. By positioning the light receiving surface close to the wall for aesthetic purposes while arranging wiring channels in the depth direction and using rear-side mounting structures, the wiring space problem is solved in a different dimensional space without compromising the aesthetic appearance from the front view
2Reliability
If the wiring line goes around the mounting part to connect solar cell modules, then the connection is achieved, but the wiring length increases and manufacturing cost increases
Solution Approach 1:
The patent extracts the wiring path from the conventional route that goes around the mounting part and creates a dedicated wiring channel through the mounting part itself. This separation of functions allows the wiring to take a direct path while the mounting part maintains its structural role, thereby reducing wiring length without compromising connection reliability
Solution Approach 2:
The mounting part serves as an intermediary structure that provides internal wiring channels. Instead of wiring going around the mounting part, the mounting part itself becomes the conduit for the wiring, facilitating a more efficient path while maintaining its primary mounting function
3Strength
If frames are provided on the four sides of the solar cell panel with mounting parts extending along the sides, then the structural support is improved, but the connection between solar cell modules becomes complex
Solution Approach 1:
The mounting part is designed to perform multiple functions: providing structural support for the solar cell panel, serving as a connection interface between adjacent modules, and containing internal wiring channels. This multi-functionality eliminates the need for separate connection structures, thereby reducing overall system complexity while maintaining structural strength

AI summary
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.
