Photovoltaic Panels Recycling Machines
With the large-scale application of photovoltaic power generation worldwide, a large number of photovoltaic modules are about to enter the decommissioning period. How to efficiently and safely dispose of these waste PV panels have become the focus of the industry, and the machines and technologies developed by SUNY GROUP related to PV panel recycling are therefore of particular importance.
The main process of PV panel recycling
Currently, the recycling of photovoltaic panels consists of three main steps: dismantling → crushing and sorting → material reuse. This process can maximize the separation of usable resources, such as silicon materials, metal frames, glass, plastic, etc., so as to achieve the recycling of resources.

Key equipment required for the dismantling process
The first step is an automatic dismantler, which is mainly used to remove the aluminum alloy frame of the PV panels and ancillary parts such as the junction box. The equipment can be cut and separated precisely to ensure the safety and efficiency of subsequent processing. Compared to traditional manual dismantling, the automatic dismantler significantly improves work efficiency and reduces the risk of personnel coming into contact with hazardous materials.
Crushing and Sorting System
The dismantled PV panels enter the crushing and sorting process. The system usually consists of a crusher, vibrating screen, magnetic separation equipment, eddy current sorting equipment, and so on.
The crusher breaks the PV panels into small particles, which is convenient for subsequent screening.
Magnetic separation and eddy current sorting equipment are further in accordance with the magnetic properties of the material, and conductivity separation.
The core of the sorting technology lies in “physical sorting”, relying on the differences in density, conductivity, and other aspects of different materials to achieve efficient separation and purification, so as to obtain silicon powder, copper, silver, glass, and other recyclable materials.
Photovoltaic recycling equipment is not only a means of resource treatment but also an important part of the green energy closed-loop system. It connects the end point of energy use and the beginning point of resource regeneration and promotes the development of the PV industry in the direction of being more environmentally friendly and efficient. With the continuous maturation of technology and improvement of policy, the future PV recycling market will usher in a broader prospect.
