ls there any recycling value for scrapped solar photovoltaic panels? And how to recycle?

Scrapped solar photovoltaic (PV) panels indeed hold substantial recycling value, given the recoverable materials they contain. As solar photovoltaic panels reach the end of their functional life, estimated to be approximately 25 to 30 years, how to recycle scrapped solar photovoltaic panels becomes critical. Recycling end-of-life solar photovoltaic panels not only alleviates the environmental issues associated with waste disposal, but also recovers valuable resources for reuse in manufacturing. The process is typically driven by specialized solar panel recycling machine and involves multiple stages to ensure efficient material recovery.

Recycling value of scrapped solar photovoltaic (PV) panels:

Solar PV panels are composed of various materials, including glass, aluminum frames, silicon cells, polymers, and trace amounts of metals like silver, copper, and lead. Each of these components has its own recycling potential:

Glass: Makes up about 75% of solar photovoltaic panels and can be recycled into new glass products.

Silicon cells: High-value component, accounting for roughly 10%, can be smelted and refined back into solar-grade silicon or used in electronics.

Metals: Copper wiring and aluminum frames are readily recyclable and have high market demand.

Plastic: The encapsulation and backsheet plastics can be used to make new photovoltaic modules or other plastic products. Backsheet materials usually have good weather resistance and insulation, so their utilization value is high.

Solar panel recycling machine and recycling process:

Henan DOING environmentally friendly solar photovoltaic panel recycling machine extracts silicon powder, copper powder and plastic with high market value through physical crushing and sorting. Recycling of solar photovoltaic panels involves the following steps, often performed using specialized solar panel recycling machine.

The recycling process of solar photovoltaic recycling machine is generally divided into three steps: 1. Disassemble the module by machine or manually, removing the backsheet, wires and aluminum frame; 2. Remove glass; 3. Crush and sort the remaining panels to extract the metal, silicon and plastic. The specific process is as follows.

1.DOING solar panel recycling machine is equipped with a frame dismantling machine, which uses mechanized and automated technologies to dismantle aluminum frames of scrapped solar photovoltaic panels with high efficiency and stability.

2.Through a solar panel glass removing machine, the glass on the surface of the solar photovoltaic panel can be removed.

3.Solar photovoltaic panels with aluminum frames and glass removed enter the double-shaft shredder. The shredder tears the photovoltaic panels into strips. Next, the strip material enters the crusher and is broken into small pieces.

4.Through negative pressure feeding, these small pieces will enter the grinder (pulverizer). If the ground particle size is not up to standard, return it to the grinder and grind it again. Qualified particles enter the air separator. Metal powder is screened out from one side of the air separator, with plastic and a small amount of metal on the other side. These plastics and small amounts of metal enter the electrostatic separator. Pure plastic and metal are sorted out again.
