Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Solar panels in large grids become dirty over time, affecting their energy absorption efficiency, and existing cleaning methods are time-consuming and require careful handling to avoid dislodging the panels.
Innovation Solution
A movable frame with frame wheels, nozzles, and brushes that can be adjusted for pressure and direction, allowing for automated or manual cleaning while maintaining panel alignment and accommodating panel gaps, with features like squeegees and covers for efficient cleaning and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual cleaning methods are used, then the cleaning can be performed with simple equipment, but the cleaning process is time-consuming and labor-intensive
Solution Approach 1:
The cleaning system is designed to be self-propelled along the solar panels using the panels themselves as the track. The frame moves automatically along the grid without requiring external propulsion equipment, operators manually guide it, and the cleaning components (brushes, nozzles) are self-contained on the frame, enabling efficient cleaning with minimal equipment complexity
Solution Approach 2:
The frame structure serves multiple functions: it supports the cleaning components (brushes, nozzles), provides the moving mechanism along the panels, and acts as the structural platform for the entire cleaning system. This multi-functionality increases productivity while avoiding the need for separate propulsion and support systems
2Productivity
If cleaning pressure is increased to improve cleaning effectiveness, then the cleaning efficiency improves, but the risk of dislodging or damaging the solar panels increases
Solution Approach 1:
The frame structure is designed with specific geometric configurations and support elements that distribute the cleaning pressure locally across multiple contact points. The cleaning components are positioned to apply force distributed over the panel surface rather than concentrated at single points, maintaining cleaning effectiveness while preventing panel dislodgement
Solution Approach 2:
The frame includes cushioning or damping elements that absorb excess cleaning force before it reaches the solar panels. This pre-cushioning mechanism ensures that even when higher cleaning pressure is applied, the panels are protected from forces that could cause dislodgement or damage
3Adaptability or versatility
If the cleaning system is designed to accommodate panel gaps and bumps, then the adaptability to different panel configurations improves, but the structural complexity of the frame increases
Solution Approach 1:
The frame structure incorporates dynamic elements that allow it to adapt to panel gaps and surface variations during movement. The frame can flex or adjust its configuration as it moves along the solar panel grid, accommodating bumps and gaps without requiring complex adjustment mechanisms or reducing structural simplicity
