Solar panels can convert light energy into electrical energy, bringing great convenience to outdoor lighting. As a new energy source, solar energy greatly reduces environmental pollution, but it may also involve another issue. So, are these devices that utilize these new energy sources, such as damaged or scrapped solar panels, causing new pollution? This involves the issue of recycling solar panels, so how can scrapped solar photovoltaic panels be recycled and reused?
Photovoltaic panel recycling and processing equipment
In fact, many materials used in the production of solar panels can still be recycled, such as the core material crystalline silicon, which can be reused in the heavy metal industry, glass panels that can be sent to the glass manufacturing industry, aluminum frames that can be sent to aluminum refineries, cables and connectors that can be crushed and reused in the form of copper beads, and waste plastics that can be used as fuel… Therefore, as long as they are handled properly, there is no need to worry too much about the new pollution or resource waste caused by the scrapping of solar panels. The photovoltaic panel recycling equipment developed now can effectively recycle and reuse photovoltaic panels without causing pollution. Below, we will formally introduce this specific process flow:
The specific process of photovoltaic panel recycling equipment is as follows: firstly, remove the glass from the photovoltaic panel; The second step is to disassemble and remove the back panel and wires; The third step is to break the components and remove the tempered glass on the outside; The fourth step is pyrolysis, which aims to dissolve EVA; The next step is extraction, which involves extracting valuable metals and silicon materials from the components. It has been officially put into operation and can separate, sort, process, and recycle 95% of the materials in crystalline silicon photovoltaic panels: 2/3 of the glass is recycled into broken glass and sent to glass manufacturing plants; The aluminum frame is sent to the aluminum refining plant; Waste plastics can be used as fuel in cement plants; The recycled silicon can be reused in the precious metal industry; The remaining cables and connectors are crushed and sold in the form of copper beads.
