Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Two-dimensional photovoltaic module arrays face cooling inefficiencies and increased wind pressure due to contiguous mounting, leading to reduced power output and the need for heavier structural supports.
Innovation Solution
A three-dimensional array assembly with overlapping vertically spaced grid layers and interconnected web members, allowing photovoltaic modules to be arranged in non-overlapping vertical relationships, with peripheral frames overlapping to maintain exposure and facilitate cooling and wind passage, and a two-axis mount for solar tracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If photovoltaic modules are mounted in two-dimensional planar arrays in contiguous side-by-side relationship, then the structural support is simpler, but the cooling of individual photovoltaic modules is hindered and wind pressure on supports increases
Solution Approach 1:
The patent transitions from a two-dimensional planar array to a three-dimensional array structure with multiple vertically spaced grid layers. This dimensional change allows modules to be arranged in successive layers where none vertically occludes another, creating interlayer spacing that enables cooling airflow and reduces wind pressure while maintaining structural efficiency.
2Ease of manufacture
If photovoltaic modules are mounted in two-dimensional planar arrays in contiguous side-by-side relationship, then the installation is simpler, but the power output of individual modules is reduced
Solution Approach 1:
By arranging modules in three-dimensional space across multiple grid layers rather than flat two-dimensional planes, the invention enables better thermal management and solar exposure for each module. The vertical spacing prevents overheating and maximizes power generation while the modular grid structure maintains installation efficiency.
3Quantity of substance
If photovoltaic modules are mounted in two-dimensional planar arrays, then the material usage is lower, but heavier structural supports are required to withstand wind pressure
Solution Approach 1:
The three-dimensional array configuration distributes modules across multiple vertically spaced grid layers, creating a more aerodynamic structure that reduces wind pressure. This spatial distribution allows for lighter support structures compared to two-dimensional arrays, while the modular grid design optimizes material usage across the extended structure.
