Retractable Solar Panel Orientation for Radiative Heat Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional solar panels on movable bodies face issues with insufficient radiative heat release during retraction, leading to temperature rises that exceed the heatproof range of the panel base material.
Innovation Solution
The solar panel is designed to retract with its light receiving surface facing the support body, allowing heat to be efficiently released through the light reflecting surface, and is pivotally mounted on a movable body to optimize sunlight exposure.

1Volume of moving object
If the solar panel is retracted by folding, then the solar panel can be stored compactly, but the radiative heat release is insufficient causing temperature to rise
Solution Approach 1:
The patent applies inversion by changing the retraction orientation from the conventional approach (light receiving surface facing outward) to the opposite approach (light receiving surface facing the support body). This inversion allows the light reflecting surface to face outward, enabling effective radiative heat release while maintaining compact storage. The back surface of the solar panel is designed with high reflectivity to efficiently radiate heat to the external environment during retraction.
Solution Approach 2:
The patent changes the orientation parameter of the solar panel during retraction. Instead of maintaining a fixed retraction posture, the system adjusts the panel's attitude so that the light receiving surface faces the support body and the light reflecting surface faces outward. This parameter change optimizes heat radiation efficiency while preserving the compact folded state.

If the solar panel is expanded to increase power generation area, then electric power generation increases, but the panel material may exceed heatproof temperature range
Solution Approach 1:
The patent applies inversion by orienting the light reflecting surface outward during operation, which is opposite to the conventional design where the light receiving surface faces outward. This inversion enables the panel to effectively radiate heat to the external environment while maintaining high power generation efficiency, preventing temperature from exceeding the heatproof range of the panel material.
Solution Approach 2:
The patent converts the potentially harmful effect of solar heat absorption into a beneficial effect by utilizing the light reflecting surface for radiative heat release. The high reflectivity of the back surface allows the panel to efficiently emit absorbed heat to the external environment, transforming the heat problem into an effective cooling mechanism that enables sustained high-power operation.
3Productivity
If the light receiving surface faces outward for maximum sunlight exposure, then power generation efficiency is maximized, but heat dissipation is insufficient
Solution Approach 1:
The patent applies inversion by reversing the conventional orientation arrangement. Instead of having the light receiving surface face outward for both power generation and heat dissipation, the system inverts the configuration so that the light reflecting surface faces outward. This enables the panel to maintain high power generation efficiency while simultaneously achieving effective radiative heat dissipation to the external environment.
Solution Approach 2:
The light reflecting surface serves dual functions: it reflects sunlight away from the panel during operation and acts as an efficient radiative heat release surface. This multi-functionality allows the panel to simultaneously maximize power generation and minimize temperature rise, resolving the contradiction between power generation efficiency and heat dissipation.
