How to recycle solar panels? What's the recycling process?

Solar panels are a vital component of renewable energy systems, but they have a limited lifespan. As these panels reach the end of their life, it is important to recycle them properly to minimize waste and environmental impact. Solar panel recycling machine is specifically designed to extract valuable materials from old solar panels, allowing for their reuse. In this article, we will discuss the working process of DOING solar panel recycling machine.

Solar panel recycling machine

The structure of solar panel recycling machine is mainly divided into three parts: aluminum frame removing machine, glass removing machine, solar panel crushing and sorting equipment. After sufficient processing and sorting, the solar panel recycling machine can systematically recycle aluminum frames, glass, metal, silicon and plastic from old solar panels.

The solar panel recycling process involves three stages, each requiring technology and equipment.

Aluminum frame removing: Use an aluminum frame removing machine to remove any non-recyclable components such as frames and junction boxes. The remaining panels are then ready for the main recycling process.

Glass removing: Then use a solar panel removing machine to remove most of the glass from the surface of old solar panels.

Crushing and Sorting: The solar panels with aluminum frames and glass are removed into the shredder. The shredder tears the solar panels into strips. Next, the material enters the crusher. The crusher breaks the material into small pieces of 1-2 cm. Through negative pressure feeding, these small pieces will enter the fine grinder. If the size of the ground material is unqualified, return to the fine grinder to continue grinding. Qualified size enters 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 metals go into an electrostatic separator, which separates pure plastics and metals. Finally, different types of materials are screened and sorted. These materials can include glass, copper, silicon and plastic.

Final products

The components in solar panels consist of good quality glass, aluminium frames, silicon, copper and silver paste (used for the printed conductors on each cell), all of which (up to 95%), can in principle be successfully recycled. Each of these materials can be reused in various industries. This is why solar panel recycling machine plays a vital role in the sustainable economy of end-of-life solar panels.

The advantages of DOING solar panel recycling machine:

1.Easy to operate, saving labor, high separation efficiency, low cost, easy to handle on a large scale.

2.Reasonable structural layout, stable performance and low noise.

3.Low maintenance cost and extremely long service life.

4.The pulse dust removal system can effectively capture dust, and the dust removal rate can reach 99.5%.

5.Solar panel recycling machine adopts dry type physical crushing and separation method, no water, no fire, no chemical, completely environmental friendly.

6.Equipped with pulse dust collector, which can effectively suppress dust volatilization and prevent secondary pollution.
