Solution Overview
Problem
Photovoltaic apparatuses face operational instability due to high temperatures, particularly in locations where the control panel is exposed to direct sunlight and radiant heat, leading to potential failure of electronic components.
Innovation Solution
A photovoltaic apparatus design where the power generation part and function part are positioned such that the back surface of the power generation part faces the function part, with a position changeable part allowing them to change positions while maintaining this orientation, thereby blocking direct sunlight and radiant heat from reaching the function part.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the control panel is mounted on the post to facilitate maintenance, then ease of operation is improved, but the control panel is exposed to direct sunlight and radiant heat causing temperature rise
Solution Approach 1:
The control panel is extracted from the post structure and integrated with the photovoltaic panel assembly. By making the control panel movable together with the photovoltaic panel, it is taken out from the fixed hot location on the post and relocated to a position that can be cooled by wind while maintaining operational accessibility.
Solution Approach 2:
The control panel is transformed from a static fixed position on the post to a dynamic position that moves with the photovoltaic panel. This dynamic relocation allows the control panel to be positioned in areas with better air circulation for cooling while maintaining ease of access for maintenance operations.
2Temperature
If the control panel is positioned away from direct sunlight to reduce temperature, then temperature control is improved, but the structure becomes more complex
Solution Approach 1:
The control panel is merged with the photovoltaic panel assembly, forming an integrated unit. This combination eliminates the need for separate mounting structures and complex positioning mechanisms, as the control panel naturally moves with the photovoltaic panel to achieve optimal thermal conditions.
Solution Approach 2:
The photovoltaic panel assembly serves multiple functions: it generates electricity, tracks sunlight, and simultaneously relocates the control panel to optimal thermal positions. This multi-functionality reduces the need for additional dedicated structures for temperature control.
