With the rapid development of the global solar photovoltaic industry, a large number of solar photovoltaic panels are gradually entering the scrap period. However, these waste photovoltaic panels are not worthless; the key materials such as silicon and aluminum in them have huge recycling potential.

Silicon, as the core material of photovoltaic panels, has extremely high recycling value in waste photovoltaic modules. According to relevant statistical data, the recycling value of silicon materials per ton in waste photovoltaic modules is about 1,500 US dollars. Through advanced photovoltaic panel recycling and processing equipment, the extraction efficiency of silicon powder is gradually improving, which further increases the value of its recycling market. The recycled silicon can be reused in the manufacture of new photovoltaic modules after purification and other processes, greatly reducing production costs.

The aluminum frame is another part with significant recycling value in photovoltaic panels. In the overall structure of the photovoltaic panel, the aluminum frame plays an important role in supporting and protecting. At present, the recycling value of aluminum frames is about 2,000 US dollars per ton. After professional photovoltaic panel frame dismantling machines and regeneration treatment, these recycled aluminum materials can be re - invested in the production and manufacturing process, realizing the circular utilization of resources.

From an environmental perspective, recycling silicon and aluminum from waste solar photovoltaic panels helps reduce the exploitation of new raw materials, lower energy consumption and carbon emissions. From an economic perspective, the recycling industry can not only create new economic growth points but also bring considerable benefits to related enterprises.

However, the current waste solar photovoltaic panel recycling industry still faces some challenges, such as the further optimization of recycling technology, the reduction of recycling costs, and the improvement of the recycling system. But with the continuous progress of technology and the gradual maturity of the market, the recycling value of silicon and aluminum in waste solar photovoltaic panels will become more and more prominent, injecting new vitality into sustainable development.
