Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional solar modules are unsightly on residential roofs, obscure architectural features, and have irregular edges that can lead to water retention and damage, while existing solutions fail to integrate seamlessly with shingle roofs.
Innovation Solution
A solar power system with uniform-sized solar modules and dummy panels that match in size, aspect ratio, and coloring, allowing for edge treatments to smooth irregular edges and create a continuous perimeter, enhancing both aesthetics and water shedding capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If traditional solar modules are installed on residential roofs, then solar energy generation is achieved, but the aesthetic appearance and architectural features of the roof are obscured
Solution Approach 1:
The patent uses dummy panels that replicate the visual appearance, size, and coloring of traditional solar modules without containing photovoltaic cells. These dummy panels are installed in non-visible areas or areas where solar generation is not needed, creating a visual copy that maintains aesthetic continuity while allowing the actual solar modules to be positioned optimally for energy generation
Solution Approach 2:
The solar array is segmented into functional solar modules for energy generation and aesthetic dummy panels for visual continuity. This segmentation allows different portions of the roof to serve different purposes - some areas generate electricity while others maintain the architectural appearance, resolving the contradiction between energy generation and aesthetics
2Productivity
If solar modules are installed to maximize energy generation, then productivity is improved, but irregular edges create water retention and potential damage
Solution Approach 1:
The patent incorporates edge treatments and dummy panels during the initial installation phase to create continuous perimeter edges and smooth irregularities before water exposure occurs. This preliminary action prevents water retention issues from developing, ensuring both productivity and reliability are maintained from the start
Solution Approach 2:
Different portions of the solar array receive different treatments - the central areas contain functional solar modules optimized for energy generation, while the perimeter edges receive special treatment with dummy panels and edge coverings that ensure proper water shedding. This local differentiation allows each area to optimize its primary function while supporting the overall system reliability
3Shape
If dummy panels are added to smooth edges and improve aesthetics, then appearance and water shedding are enhanced, but device complexity increases
Solution Approach 1:
The dummy panels are designed to be homogeneous in appearance with the functional solar modules - same size, coloring, and visual characteristics. This homogeneity allows the dummy panels to blend seamlessly into the array, creating uniform edges and improving aesthetics without introducing visually complex or heterogeneous elements that would increase perceived system complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system integrates solar energy generation with residential roof aesthetics, preventing water accumulation and enhancing structural integrity by creating a uniform edge that mimics traditional shingles, improving both appearance and functionality.

Data Source
AI summary
A roof-mounted solar power system for generating electrical power that includes a plurality of solar modules adapted for generating electrical power from sunlight, and with each of the plurality of solar modules having substantially the same size, aspect ratio and surface coloring. The plurality of solar modules are mounted on the deck of a roof to form a bank of solar modules having at least one irregular edge. The solar power system further includes one or more non-power generating edge treatments having substantially the same size, aspect ratio and surface coloring as the solar modules and that are adapted for installation along the irregular edge. Each edge treatment is adapted for a cutting away of at least one corner thereof to smooth the irregular edge of the bank of solar modules to a regular edge.
