Solar Cell Assembly With Backside Adhesive and Bolt Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional solar cell clamping assemblies are prone to reduced clamp force due to aging under UV, water vapor, and corrosion, and have poor resistance to air and snow pressure, leading to potential deformation and damage, while requiring high installation accuracy and being unsuitable for installation near the ground.
Innovation Solution
A solar cell module with an installation member featuring a supporting portion on the backside of the solar panel and a connecting portion extending parallel to the panel, allowing for adhesion and bolt fixation to a support beam, enhancing safety and load capacity, and reducing installation accuracy requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rubber pad is used in the clamping assembly, then the solar panel can be clamped effectively, but the rubber pad ages under UV, water vapor and corrosion gases, reducing clamp force and causing the solar panel to drop off
Solution Approach 1:
The patent removes the rubber pad from the clamping assembly entirely, replacing it with a direct metal-to-glass contact design where the clamping force is applied through the metal clamp body itself, eliminating the aging component
Solution Approach 2:
The patent uses a composite structure combining metal clamp body with integrated positioning features and sealing elements, where the metal provides structural strength and the sealing elements provide protection without relying on rubber pads
2Strength
If a conventional clamping assembly is used, then the solar panel can be fixed, but the assembly has poor resistance against air pressure and snow pressure, leading to deformation and damage
Solution Approach 1:
The patent employs curved or rounded contact surfaces in the clamping assembly that better distribute concentrated loads from snow and wind pressure, preventing stress concentration and deformation
Solution Approach 2:
The clamping assembly is divided into multiple independent clamping points along the solar panel edges, allowing each segment to independently bear localized loads from air pressure and snow, preventing overall structural deformation
3Ease of operation
If the fixing assembly is disposed on the back of the solar cell assembly, then the solar panel can be fixed, but the mounting point location requires relatively high accuracy, especially when the solar panel is near the ground
Solution Approach 1:
The patent changes the positioning parameters of the clamping assembly to provide a larger tolerance range for mounting hole locations, and incorporates adjustable positioning features that can accommodate variations in hole position without requiring high precision
Solution Approach 2:
The patent introduces positioning pins or guide features as intermediaries between the clamping assembly and the solar panel mounting holes, which automatically align and accommodate position deviations, making the installation process more tolerant of location inaccuracies
