Inter-Facing Solar Panel Layout for Reflected Light Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional solar panels face inefficiencies in maximizing energy collection due to reflected sunlight, as they are typically positioned in a single plane and require anti-reflecting coatings to minimize reflection.
Innovation Solution
The method involves positioning solar panels to inter-face each other, allowing sunlight to be reflected between them, with both sides coated with active photovoltaic layers, eliminating the need for anti-reflecting coatings and optimizing energy conversion across different wavelengths and dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If solar panels are positioned in a single plane facing the sun, then the structure is simple and easy to install, but a significant portion of sunlight is reflected back to space, reducing energy collection efficiency
Solution Approach 1:
The patent transitions from a conventional single-plane solar panel arrangement to a three-dimensional inter-facing configuration where panels are positioned at angles to each other (e.g., 45 degrees). This dimensional change allows sunlight to be reflected between panels, enabling multiple absorption opportunities and reducing the portion of sunlight reflected back to space, thereby resolving the contradiction between structural simplicity and energy collection efficiency.
Solution Approach 2:
The patent converts the harmful effect of reflected sunlight (which normally represents energy loss) into a beneficial resource by positioning panels to intercept and absorb the reflected light. The reflection that would otherwise be wasted is now captured by adjacent panels, transforming an adverse factor into a useful energy source and improving overall system efficiency.
2Loss of energy
If anti-reflecting coatings are applied to solar panels, then reflection is reduced and energy absorption is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent extracts and removes the anti-reflecting coating layer from the solar panel structure. Instead of applying complex coatings to reduce reflection, the invention uses a geometric arrangement of inter-facing panels that naturally captures reflected sunlight through their positioning and angular relationships, thereby eliminating the need for additional coating materials and simplifying the device structure.
Solution Approach 2:
The patent replaces the chemical/optical approach of anti-reflecting coatings with a mechanical/geometric solution. By carefully positioning panels at specific angles to each other, the system uses physical geometry rather than material coatings to control light reflection and absorption, substituting a complex chemical layer with a simpler structural arrangement.
3Productivity
If solar panels are positioned vertically to sunlight direction, then energy collection efficiency is maximized, but the system cannot adapt to changing sun positions throughout the day
Solution Approach 1:
The patent merges multiple fixed solar panels into an inter-facing array where each panel contributes to both direct and reflected light absorption. This combination creates a system that maintains high efficiency at a fixed position while effectively tracking the sun's movement throughout the day, as the reflected light paths change with sun position, allowing different panels to capture light at different times without requiring individual panel movement.
