Solar Module Mounting Structure for Tolerance-Adjusted Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solar cell arrays face challenges in accurately securing solar cell modules due to dimensional tolerances, requiring reinstallation or additional work when the modules' tolerances are large, which complicates the installation process.
Innovation Solution
A solar cell array design featuring a mounting member with a first supporting member and a second supporting member, restrained by first and second restraining members, allows for easy positioning and securing of adjacent modules by determining the gap between them based on the module's dimensions, reducing the need for precise alignment and simplifying the installation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If solar cell modules are secured using conventional mounting methods with bolts, then the modules can be fastened to the base, but large dimensional tolerances of the modules make accurate positioning difficult, requiring reinstallation or additional work
Solution Approach 1:
The mounting member incorporates a movable component that allows adjustment in the direction of the solar cell module's longitudinal side. This dynamic adjustment mechanism enables the installer to compensate for dimensional tolerances by moving the mounting member to the correct position, thereby achieving accurate positioning without requiring precise pre-determination of fastening positions or reinstallation work
Solution Approach 2:
The mounting member is divided into a fixed component and a movable component. The fixed component provides stable mounting to the base, while the movable component allows for positional adjustment to accommodate dimensional variations of solar cell modules. This segmentation enables independent optimization of both stability and adjustability
2Strength
If multiple fastening points are used to secure mounting members, then structural integrity is improved, but the number of installation steps and fastening operations increases
Solution Approach 1:
The mounting member combines multiple functions into a single integrated structure: the fixed component provides structural support and stability, while the movable component enables positional adjustment. This merging allows the mounting member to achieve both high structural integrity and easy installation with reduced fastening operations, as the movable component can be adjusted without requiring additional fastening points

AI summary
A solar cell array includes solar cell modules arranged in a first-direction, and a mounting member for securing adjacent ones of the solar cell modules. The mounting member comprises a first supporting member extending in the first-direction, a second supporting member provided on the first supporting member and extending in a second-direction, a first restraint provided on one side of the second supporting member in the first-direction and configured to restrain the second supporting member from moving in the second-direction and in a height direction, and a second restraint provided on another side of the second supporting member in the first-direction and configured to restrain the second supporting member from moving in the height direction. The first restraint is movable together with the second supporting member in the first-direction on the first supporting member. The second restraint restrains the second supporting member from moving in the first-direction.
