Solution Overview
Problem
Existing soil cultivation systems with solar panels face a trade-off between insufficient light for agricultural plants and reduced power generation due to the need for light-transmitting regions, which limits the types of plants that can be cultivated and the amount of power produced.
Innovation Solution
A soil cultivation system with a solar panel that incorporates double-sided light-receiving solar cells, a light-transmitting region, a transmissive roof member, and a reflection sheet to maximize light capture and utilization for both plant growth and power generation, while maintaining a robust frame structure for efficient power generation and agricultural operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light transmitting region is provided between solar panels to increase light for plants, then the amount of light on agricultural plants is improved, but the power generation region is reduced and the amount of power generated is reduced
Solution Approach 1:
The patent transitions from two-dimensional planar solar panels to three-dimensional inclined solar panels mounted on frame units. This spatial reconfiguration allows sunlight to pass through gaps between panels while still providing adequate illumination to crops below, resolving the contradiction between light transmission and power generation by utilizing vertical and angular dimensions rather than just horizontal plane coverage
Solution Approach 2:
The patent applies different functional characteristics to different parts of the solar panel system. The solar panels are positioned at specific inclinations and spacing to create localized light transmission zones beneath them, while maintaining high power generation efficiency on the panel surfaces themselves. This spatial differentiation allows simultaneous optimization of both light availability for plants and power generation capacity
2Power
If solar panels are placed on the ground to generate power, then power generation is improved, but the area under the solar panel is not utilized and light for plants is insufficient
Solution Approach 1:
The patent elevates solar panels from ground-level horizontal placement to inclined mounting on frame units raised above the ground. This dimensional change creates space beneath the panels for crop cultivation while maintaining effective power generation surfaces, allowing both functions to coexist in the same spatial footprint

AI summary
In the soil cultivation system (80) equipped with a solar panel, a light transmitting region (A) is provided in a solar panel (50), and thus a larger amount of light is captured into a frame unit and can thereby be utilized for the cultivation of agricultural plants (P1, P2). Double-sided light receiving solar cells (52) are adopted in the solar panel (50), and thus light reflected off an agricultural ground surface, the agricultural plants (P1, P2), a sheet-shaped member and the like can be effectively utilized for power generation. In this way, it is possible to compensate for a reduction in the area of the solar cells caused by the formation of the transmitting regions A, and it is possible to obtain a large amount of power generated while acquiring the amount of light on the agricultural plants.
