Solar Panel Backside Coating for Local Crack Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Solar panel backboards deteriorate over time due to aging, cracking, and damage during transportation and installation, leading to safety and functional failures, with existing repair methods being costly, wasteful, and environmentally harmful, and lacking flexibility to address various types of defects.
Innovation Solution
A method involving the application and curing of a moisture curable composition on damaged solar panel backboards to repair scratches, holes, cracks, and micro-cracks, which is fast, economically effective, and environmentally friendly, allowing for on-site, waste-free restoration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the damaged solar module is replaced as a whole, then the functionality and safety are restored, but the cost increases extremely high and environmental pollution is caused
Solution Approach 1:
The patent applies local repair by targeting only the damaged backside areas of solar modules rather than replacing entire modules. The curable composition is applied locally to cracked or damaged regions, restoring functionality only where needed and minimizing material waste.
Solution Approach 2:
The patent enables recovery and continued use of solar modules that would otherwise be discarded. By repairing the backside damage in place, modules can be restored to functional status and remain in service, preventing them from becoming waste.
2Reliability
If the damaged solar module is replaced as a whole, then the safety requirements are met, but the cost increases extremely high
Solution Approach 1:
The patent restores safety by applying curable composition specifically to damaged backside regions where cracks or damage compromise structural integrity. This localized reinforcement meets safety requirements without the expense of complete module replacement.
Solution Approach 2:
The patent uses inexpensive curable composition materials to repair backside damage, providing a low-cost alternative to expensive module replacement while restoring safety and functionality.
3Ease of repair
If traditional repair methods are used, then some damage can be addressed, but the methods are not environmentally friendly and create waste
Solution Approach 1:
The patent enables repair capability by applying curable composition locally to damaged areas. This targeted approach maintains repair effectiveness while minimizing material consumption and environmental impact compared to whole-module replacement.
Solution Approach 2:
The patent prevents environmental harm by recovering and continuing to use damaged solar modules through backside repair. Modules that would be discarded as waste are instead restored to service, reducing landfill burden and environmental pollution.
4Reliability
If whole module replacement is performed, then functionality is restored, but time and resources are wasted
Solution Approach 1:
The patent restores functionality by applying curable composition only to damaged backside regions rather than replacing entire modules. This localized approach significantly reduces repair time while achieving the same functional restoration.
Solution Approach 2:
The patent enables quick repair by having curable composition ready for immediate application to damaged areas. The composition cures rapidly upon exposure to moisture, restoring functionality without the extended time required for module replacement logistics.
