Imitation Solar Modules for Irregular Roof Arrays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard rectangular photovoltaic modules often result in aesthetically unpleasing staggered arrays and complicate installations on irregularly shaped roofs with obstructions, limiting the array's appearance and functionality.
Innovation Solution
The introduction of imitation solar modules with triangular or non-standard shapes that provide structural support and electrical grounding, filling in gaps and accommodating obstructions, while maintaining a visually appealing appearance by mimicking functional modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If standard rectangular photovoltaic modules are used in a staggered array configuration, then the array can be installed on irregularly shaped roofs with obstructions, but the perimeter edge appears jagged and aesthetically unpleasing
Solution Approach 1:
The photovoltaic array is segmented into standard rectangular modules and custom-shaped imitation modules (triangular, trapezoidal, or custom-cut modules). These imitation modules are strategically placed at perimeter positions to fill gaps and create a smooth edge appearance, while standard modules maintain the functional core of the array.
Solution Approach 2:
Custom-shaped imitation modules with asymmetric geometries (triangles, trapezoids, or irregular polygons) are used at perimeter positions to match the specific contours of the roof and create a visually pleasing smooth edge, contrasting with the symmetric rectangular standard modules used in the array interior.
2Ease of manufacture
If standard rectangular photovoltaic modules are used, then manufacturing and installation are straightforward, but the array cannot accommodate obstructions like skylights, vents, and chimneys without complex configurations
Solution Approach 1:
The array is divided into standard rectangular modules for the main array area and custom-shaped imitation modules positioned around obstructions. This segmentation allows the majority of the array to maintain simple installation procedures while specific perimeter modules are customized to fit around skylights, vents, and chimneys.
Solution Approach 2:
Standard rectangular modules with uniform properties are used in the array interior where simple installation is prioritized, while custom-shaped imitation modules with locally adapted geometries are used at perimeter positions near obstructions to provide local adaptability without complicating the entire array installation.
3Shape
If imitation modules are used to fill perimeter gaps and accommodate obstructions, then aesthetic appearance and adaptability improve, but additional non-electricity generating modules are required
Solution Approach 1:
Imitation modules are designed to visually replicate the appearance of standard photovoltaic modules, using similar materials, colors, and surface textures. This copying approach allows the use of non-electricity generating modules at perimeter positions while maintaining a unified aesthetic appearance, making the additional modules less visually prominent.
Solution Approach 2:
The imitation modules serve multiple functions: they provide structural support for the array perimeter, create a smooth visual edge, accommodate obstructions, and maintain aesthetic consistency with standard modules. This multi-functionality reduces the need for separate structural elements and minimizes the total number of additional components required.
