With proper end-of-life management technology, the recycling rate of solar panel materials can be as high as more than 90%, which helps to improve the resource efficiency and sustainability of solar power generation. New recycling processes can even recover semiconductor materials such as silicon for reuse.

Solar panel material composition

The main recyclable materials for solar panels include aluminum frames, glass, silicon wafers, copper wire, silver flakes and plastics. The following is the recycling process and related equipment for these materials:

Aluminum frame: The aluminum frame around the solar panel can be efficiently dismantled through special disassembly equipment, and the resulting aluminum frame can be recycled again.

Glass: Special crushing and separation machines can break glass pieces into small particles and completely separate them from the solar panels for subsequent processing.

Silicon wafer: Silicon is approximately 15-20% recyclable material. Use a grinder to crush the solar panels into powder, and then use equipment such as air flow separators and electrostatic separators to separate and recycle the silicon powder.

Copper wire: Recyclable material accounts for about 5%. Recycling using dismantling machines and magnetic separators.

Silver pieces: Although the quantity is small, the value is very high. After crushing and grinding, chemical extraction is used to recover the silver.

Plastics: Recycling using crushers and separation extraction units.

In addition, a photovoltaic module disassembly machine is also required for preliminary disassembly of the modules. The entire set of equipment developed by SUNY GROUP adopts automatic control to achieve efficient separation and recycling of different materials. This equipment is considered the current best practice for photovoltaic module recycling.

By recycling and reusing solar panel materials, we can reduce resource waste and reduce the need for raw materials while minimizing the environmental impact of e-waste. Choosing solar power not only contributes to the environment but also promotes the development of sustainable energy.
