Clamp assembly and mounting assembly for a solar cell module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solar module mounting systems require attachment points on the frame, which can damage the sandwich structure and are not easily removable or adaptable to different facade designs.
Innovation Solution
A clamping arrangement using a C-shaped guide rail with L-shaped brackets and a guide inside the rail, allowing secure clamping without frame attachment points, featuring a spring mechanism for easy installation and adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mounting openings or fasteners are provided on the solar module frame, then the solar module can be securely attached to the facade, but moisture and oxygen can penetrate through the fastening points causing oxidation or short circuits
Solution Approach 1:
The patent introduces a mounting assembly as an intermediary component between the solar module and the facade structure. This assembly includes a mounting bracket and mounting rail that distribute attachment forces across multiple contact points on the frame, rather than using concentrated fasteners that penetrate the frame. The intermediary mounting assembly enables secure attachment while maintaining the integrity of the solar module's sealed structure.
2Reliability
If pre-defined mounting points are specified on the solar module frame, then secure attachment is achieved, but the facade design must be adapted to these specific mounting points, reducing flexibility
Solution Approach 1:
The mounting assembly is designed as a universal interface that can accommodate different solar module types and sizes. The mounting bracket engages with standardized features on the solar module frame, while the mounting rail provides a flexible mounting interface that can be adapted to various facade structures. This universal design allows the same mounting assembly to work with different solar modules and facade types without requiring custom adaptations.
3Strength
If the solar module is securely mounted to withstand wind and snow loads, then stability is achieved, but the mounting structure becomes more complex and visible
Solution Approach 1:
The mounting bracket and mounting rail are designed to work together as an integrated system. The mounting bracket attaches to the solar module frame, and the mounting rail attaches to the facade structure, with the bracket serving as the connecting element. This merged design consolidates multiple mounting functions into a coordinated assembly that achieves the required structural strength while maintaining a relatively simple and clean appearance.
4Reliability
If traditional fastening methods are used, then secure attachment is achieved, but the mounting is not easily removable for maintenance or replacement
Solution Approach 1:
The mounting assembly incorporates reversible attachment mechanisms that allow the solar module to be securely fixed during operation but easily removed when needed. The mounting bracket and rail use mechanical engagement features that can be quickly disengaged and reengaged, enabling maintenance personnel to remove and reinstall solar modules without complex tools or procedures, thus facilitating easy repair and replacement.

AI summary
A clamping arrangement for a solar module comprises an assembly with at least one essentially C-shaped, longitudinally extended guide rail (110) and a first and a second holder. These holders (120, 130) are essentially L-shaped, forming an angle with two legs. A first leg comprises a first, extended, straight section (121, 131); the second, angled leg or second section (122, 132) has a gripping section (123, 133) at its end. This gripping section serves to positively engage the frame of a solar module. The holders (120, 130) are inserted into the longitudinal ends of the guide rail (110). For this purpose, the interior of the guide rail (110) has a guide dimensioned such that the first section (121, 131) or leg of the holders (120, 130) is slidably guided within it. One eyelet (128) each on the bracket (120) orThe guide rail (118) can be connected via a spring (250) such that the holder (120) is drawn into the guide of the guide rail (110) and exerts a tensile force on the gripping section (123, 133). A mounting arrangement for solar cell modules for facades comprises the aforementioned clamping arrangement, a support rail, and a solar cell module.
