Inward-Facing Solar Panel Pyramidal Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional solar panels are inefficient due to reflection of sun rays at steeper angles and aesthetically unappealing when mounted on rooftops, as they protrude visibly and do not maximize energy capture from the same footprint area.
Innovation Solution
A solar panel system with solar panels arranged at an obtuse angle within a three-dimensional frame, creating an open volume where each panel faces inward, allowing for internal reflection and increased energy capture, and can be recessed into a rooftop for a hidden aesthetic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If solar panels are arranged in a conventional planar configuration, then the installation is simple and structure is straightforward, but the energy capture efficiency is limited due to reflection losses at steeper sun angles
Solution Approach 1:
The patent transitions from a two-dimensional planar panel arrangement to a three-dimensional pyramidal configuration. Multiple panels are angled inward to face a central volume, creating internal reflection paths that allow sunlight to be captured from multiple angles throughout the day, thereby improving energy capture efficiency while managing structural complexity through a systematic geometric design
2Productivity
If solar panels are mounted on rooftops to maximize sun exposure, then energy generation is optimized, but the aesthetic appearance is compromised as panels protrude visibly
Solution Approach 1:
The solar panel system is nested within a pyramidal structure that can be recessed into the rooftop. The panels are arranged inward-facing within this enclosing form, allowing the system to be integrated into the building's roofline rather than protruding outward, thus improving aesthetic appearance while maintaining energy generation capability through the internal reflection geometry
3Productivity
If solar panels are positioned to capture sunlight at various angles, then energy capture is improved, but the space required for panel installation increases
Solution Approach 1:
By arranging panels in a three-dimensional pyramidal configuration with inward-facing surfaces, the system captures sunlight from multiple angles within a compact footprint. The internal reflection geometry allows the same roof space to effectively capture more solar energy throughout the day compared to conventional flat panel arrangements
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
Enhances solar energy production efficiency by capturing more rays and providing a visually appealing, space-efficient solution by integrating solar panels into a building's interior or exterior, potentially doubling the energy output of conventional panels within the same footprint.
Implementation Method 1
each solar panel of the plurality of solar panels includes a face of solar cells facing inward into the open volume of space
Implementation Method 2
The efficiency in generating power of a conventional solar panel is limited by the angle of incidence from sun rays shining on the panels. When the sun is at steeper angles relative to solar panels, a lot of rays are lost due to reflection bouncing off the panel surface without absorption

AI summary
A solar panel system is assembled into a three-dimensional volume with the solar cell(s) positioned on an inward facing surface to collect sunlight and reflect sunlight from different angles as the sun passes overhead. Embodiments may be mounted into the interior of a building with a top end of the module being positioned on or proximate a roof surface and disposed to collect sunlight into the module interior below the roof line. Some embodiments may be pyramidal shaped. Outdoor mounting of the solar panel module includes embodiments that may be held in a frame and rail mounted system.
