Solar panel mounting assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solar panel mounting systems require fasteners and tools, increasing labor and overhead costs, and risking damage during installation, as they necessitate multiple fasteners per module and complex tool usage.
Innovation Solution
A solar racking system featuring a rail and clamp assembly with a grounding lock that allows for fastener-less mounting and electrical grounding of solar modules, using a rail assembly with internal volume and locking interfaces to secure the module without tools or fasteners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fastening hardware (nuts, bolts, washers, clamps) is used to mount solar modules, then adequate mounting strength and electrical grounding are achieved, but labor and overhead expenses increase due to required tools and complex installation procedures
Solution Approach 1:
The patent combines multiple functions into a single integrated mounting element. The U-shaped mounting element with integrated locking arms and grounding contacts eliminates the need for separate fasteners, clamps, and grounding hardware, thereby reducing tool requirements and installation complexity while maintaining mounting reliability
Solution Approach 2:
The U-shaped mounting element serves multiple functions simultaneously: it provides structural support, mechanical locking through retractable arms, electrical grounding via integrated contacts, and module retention. This multi-functionality replaces traditional multi-component fastening systems
2Ease of operation
If mounting clamps are hammered onto frame rails to secure solar modules, then fastener-less mounting is achieved, but installation damage risk increases due to hammering forces
Solution Approach 1:
The locking arms are pre-configured in a retracted position within the mounting element, allowing the module to be first positioned onto the rail without force. The arms then automatically engage and lock the module in place, eliminating the need for hammering or impact forces during installation
3Reliability
If multiple fasteners per module are used in traditional mounting systems, then secure mounting is achieved, but material costs and installation time increase
Solution Approach 1:
Multiple fastening functions are merged into a single U-shaped mounting element with integrated locking arms. Instead of installing multiple separate fasteners, the system uses one mounting element that automatically engages and secures the module, significantly reducing installation time and material usage
