Current solar panel mounting structures are complex and inefficient, requiring improved designs to simplify installation and enhance performance for photovoltaic module mounting on structures like roofs.
Innovation Solution
A modular apparatus comprising a bracket, clamp, and footer with adjustable positioning and securement mechanisms, along with bonding clips and trim/micro-inverter mounting brackets, allows for secure, efficient, and flexible mounting of multiple photovoltaic modules on a roof structure, enabling easy alignment and electrical bonding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If traditional mounting structures are used, then photovoltaic modules can be mounted on roofs, but the structure becomes complex and installation efficiency decreases
Solution Approach 1:
The mounting structure is divided into separate functional components: rails that provide structural support and alignment, clamps that secure modules to rails, and bonding clips that provide electrical connectivity. This segmentation allows each component to be optimized independently and simplifies installation by enabling modular assembly.
Solution Approach 2:
The rail system serves multiple functions simultaneously: it provides mechanical support for modules, establishes alignment between adjacent modules, enables adjustable positioning through slot configurations, and facilitates electrical bonding through integrated bonding clips. This multi-functionality reduces the number of separate components needed.
2Adaptability or versatility
If fixed positioning mechanisms are used, then module alignment is achieved, but adaptability to different roof configurations is reduced
Solution Approach 1:
The system incorporates adjustable positioning mechanisms where clamps can be positioned at various locations along the rails using slot configurations. This dynamic adjustability allows the same mounting structure to adapt to different roof pitches, module sizes, and installation configurations while maintaining precise alignment through the rail-guided positioning system.
Solution Approach 2:
The rail acts as an intermediary element between the roof structure and the photovoltaic modules. It provides a standardized interface that accommodates various roof configurations while ensuring precise module alignment through its geometric features and slot configurations, decoupling the alignment function from the specific roof geometry.
3Reliability
If mechanical mounting only is used, then structural support is provided, but electrical bonding efficiency is reduced
Solution Approach 1:
The bonding clip integrates mechanical clamping function with electrical bonding function into a single component. The same mechanism that secures the module to the rail structure also establishes electrical connectivity through integrated contact points, eliminating the need for separate mechanical fasteners and electrical connectors.
Solution Approach 2:
The bonding clip serves dual functions: it provides mechanical retention of the module to the mounting structure and simultaneously establishes electrical bonding for current collection. This multi-functionality simplifies the overall system by combining what would traditionally require separate components into a single integrated element.
