Therefore, establishing a recycling and reuse project for discarded photovoltaic panels is of great significance for resource recovery and environmental protection.
Currently, the mainstream recycling technologies for photovoltaic panels primarily include physical dismantling and chemical pyrolysis.
Physical disassembly method: An automated disassembly line can achieve an efficiency of processing 50 components per hour, with an aluminum frame recycling rate of 98%, but the silicon material utilization rate is less than 60%.
Pyrolysis technology: Separates EVA film, enhancing the purity of glass to 99.2%, with an annual processing capacity of 100,000 tons.
The physical dismantling process is more refined, with relatively lower energy consumption and less environmental pressure.
The chemical pyrolysis process has stricter requirements for equipment and exhaust gas treatment systems, with relatively higher costs, but it can handle larger quantities.
