The adoption of solar energy continues to grow, and so does the need for effective end-of-life management of solar panels. Proper dismantling and recycling of solar panels is critical to minimize waste and recover valuable materials. Now let’s take a look at the equipment involved.
Types of main dismantling equipment for solar panels
Steps in the Solar Panel Disassembly Process
There are roughly two main types of solar panels, silicon-based and thin-film-based. Currently, silicon-based panels are more common, but that doesn’t mean that thin-film-based cells don’t have great value. Research studies conducted on the topic of recycling solar panels have resulted in numerous technologies. Some even reach an astonishing 96% recycling efficiency, but the aim is to raise the bar higher in the future.
Engineers are exploring new technologies that can improve efficiency and reduce material loss. They are also trying to simplify the sorting and dismantling process to make recycling more efficient and cost-effective.
The physical recycling process of solar panels is mainly divided into four steps:
- Remove the aluminum frame and junction box by machine.
- Remove the tempered glass.
- Crush the panels, then sort the silicon powder, copper powder and EVA powder.
- Extract silver from silicon powder.
The pyrolysis process of solar panels generally has four main steps:
- Remove the aluminum frame and junction box by machine.
- Next step is solar photovoltaic panel pyrolysis.
- Sort the waste photovoltaic panels.
- Extract silver from silicon powder.
Benefits of Solar Panel Disassembly Equipment
- 1
Compact structure. Reasonable layout and stable performance. Low noise.
- 2
The waste circuit board recycling equipment adopts two-stage crushing to make the crushing finer. Return system makes crushing more efficient.
- 3
The waste circuit board recycling equipment adopts PLC to control the whole production line, and the whole production line is unified feeding and coordinated operation.
- 4
The whole production line adopts negative pressure feeding, which effectively reduces the dust overflow.
- 5
Equipped with magnetic sorting function, which can separate iron from the material. The sorting rate of air flow sorting equipment can reach 99%. High voltage electrostatic sorting machine makes the sorting more efficient and effectively controls the loss of non-ferrous metals.
- 6
