Photovoltaic module mounting structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting structures for photovoltaic modules are inflexible, unable to accommodate both landscape and portrait orientations, do not effectively reduce shading, and require post-installation grounding, which is costly and risky.
Innovation Solution
A dual-tilt mounting structure that allows for both landscape and portrait orientations, reduces shading by optimizing PV module placement, and establishes grounding paths during construction using clamps and fasteners to secure PV modules to support rails.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed mounting structure is used, then the structure is simple to manufacture, but it cannot accommodate both landscape and portrait orientations of PV modules
Solution Approach 1:
The mounting structure incorporates adjustable rails that can be positioned at different angles and orientations. The rails are designed to accommodate PV modules in both landscape and portrait orientations through adjustable mounting positions and configurable rail arrangements, allowing the system to adapt dynamically to different module configurations without requiring multiple fixed structures
Solution Approach 2:
The mounting structure uses universal support rails and clamps that can secure PV modules in multiple orientations. The same rail system serves both landscape and portrait mounting configurations, eliminating the need for separate mounting structures for different orientations and reducing overall system complexity while maintaining versatility
2Object-affected harmful factors
If PV modules are mounted in traditional fixed positions, then installation is straightforward, but shading is not adequately reduced
Solution Approach 1:
The mounting structure enables dynamic adjustment of PV module positions and angles through adjustable rails and mounting positions. This allows optimization of module placement to minimize shading from surrounding objects and structures, while maintaining ease of installation through standardized adjustable components that simplify the positioning process
Solution Approach 2:
The mounting structure provides localized adjustment capabilities at each module position, allowing individual modules to be positioned optimally to reduce shading. The adjustable rails and mounting positions enable site-specific optimization of module placement without requiring complex overall structural changes
3Reliability
If complex grounding setups are required, then safety is improved, but installation time and complexity increase
Solution Approach 1:
The grounding function is integrated into the mounting structure itself through conductive rails and clamps that provide electrical connectivity. The mounting components serve dual purposes: mechanical support and electrical grounding, eliminating the need for separate grounding installations and reducing overall installation time while maintaining safety
Solution Approach 2:
The mounting structure provides self-grounding capabilities through its conductive components. As modules are mounted to the rails using the provided clamps and fasteners, electrical connectivity and grounding are automatically established without requiring additional grounding wires or separate grounding procedures
