How to recycle waste photovoltaic modules?

Photovoltaic modules play a vital role in the field of solar power generation. However, with the increase of service life and the upgrading of technology, a large number of waste photovoltaic modules will be generated. How to effectively recycle these photovoltaic modules is not only related to the effective recycling of resources, but also one of the keys to achieving sustainable development goals. In this context, solar panel recycling machines designed according to their structural characteristics have become an important tool to solve this problem.

In order to make everyone more deeply aware of the importance of solar panel recycling machines in solving this problem, we first need to understand the structural characteristics of photovoltaic modules, the working process of solar panel recycling equipment, and the advanced features of this technology.

Composition of photovoltaic modules:

Photovoltaic modules are mainly composed of solar cells, glass, packaging materials (such as EVA film), backplane and frame. Solar cells are the core components that convert solar energy into electrical energy and are usually made of silicon. Glass covers the top of the cell to protect and transmit light. EVA film is used to seal the cell to prevent moisture and oxygen from entering. The backplane is located on the back of the cell and provides electrical insulation and physical protection. The frame serves to fix and support the entire module. Photovoltaic modules contain rich recyclable resources, such as aluminum, silicon, silver and other metal elements. These materials can be processed and recycled through solar panel recycling machine.

In the recycling of photovoltaic modules, there are special disassembly equipment that can effectively separate the aluminum frame, glass, and solar cells with great precision. First, the frame removing machine plays an important role in the initial disassembly. It can accurately remove aluminum frame on the photovoltaic panels. Then, glass removing machine gradually softens the EVA film between the glass and the solar cells by precisely controlling the temperature, thereby separating the glass and solar cells. After disassembly, the aluminum frame and glass can be directly recycled, while the solar cells and other parts require further processing.

The disassembled solar cells are broken into small pieces by crushing equipment for subsequent processing. In this step, professional crushing equipment, such as shredders, crushers, grinders, etc., to fully crush the waste photovoltaic panels. After being fully crushed, the particles enter the physical separation stage. This stage uses the differences in physical properties such as density and magnetism of different materials in photovoltaic panels to separate copper, silicon, plastic, etc.

In addition to the above main steps, solar panel recycling machine is also equipped with corresponding auxiliary equipment and systems, such as dust removal system, PLC control system, etc., to ensure the environmental protection and sustainability of the entire recycling process.

In actual applications, photovoltaic panels of different types and specifications may have differences in structure and materials, so it is necessary to select appropriate solar panel recycling machine and technology.
