Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional photovoltaic module installations face challenges with wind deflector design, including labor-intensive installation, quality issues, and fixed ground coverage ratios, which hinder optimal sunlight collection and maintenance access.
Innovation Solution
A photovoltaic module assembly with a removably mounted wind deflector, featuring a clip and support arm configuration that allows for adjustable orientations and easy installation without tools, enabling flexible wind deflection angles and reduced footprint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wind deflectors are permanently affixed as part of the PV module, then wind protection is improved, but installation complexity and labor time increase
Solution Approach 1:
The wind deflector is separated from the PV module into independent components. The deflector can be independently attached or removed from the PV module frame, allowing simplified installation and maintenance while maintaining wind protection functionality when needed.
2Reliability
If wind deflectors are permanently affixed, then wind protection is improved, but manufacturing and shipping costs increase
Solution Approach 1:
By separating the wind deflector from the PV module, each component can be manufactured and packaged independently. This reduces overall packaging volume and shipping costs, while allowing the deflector to be added only when wind protection is required at the installation site.
3Ease of manufacture
If a fixed wind deflector design is used, then manufacturing is simplified, but adaptability to different installation sites is reduced
Solution Approach 1:
The wind deflector system transitions from a fixed design to a dynamic, adjustable configuration. The deflector can be attached at different positions and angles to the PV module frame, allowing adaptation to various wind conditions and installation site requirements while maintaining straightforward manufacturing of the individual components.

AI summary
A photovoltaic (PV) module assembly including a PV module, a deflector, and a clip. The PV module includes a PV device and a frame. A PV laminate is assembled to the frame, and the frame includes a support arm forming a seat. The deflector defines a front face and a rear face, with the clip extending from either the trailing frame member or the rear face of the deflector. In a mounted state, the deflector is nested within the seat and is releasably mounted to the trailing frame member via the clip. In some embodiments, the support arm forms a second seat, with the PV module assembly providing a second mounted state in which the deflector is in a differing orientation/slope, nested within the second seat and releasably mounted to the trailing frame member via the clip.
