How to recycle old photovoltaic panels?

As solar energy becomes a core part of the world's renewable transition, the number of old photovoltaic panels is skyrocketing—millions of tonnes will reach the end of their life by 2030. But here's the critical point: improper handling of these panels isn't just a waste of valuable materials like aluminum, silicon, and glass—it also risks leaking toxic substances into soil and water, harming ecosystems and human health. So, how do you recycle old PV panels in a way that's safe, efficient, and compliant?

DOING's photovoltaic panel recycling machine utilizes a state-of-the-art physical processing method that requires no chemical agents, guaranteeing an environmentally safe and clean operation. The integrated setup includes specialized machinery such as aluminum frame dismantling machines, glass removal units, double-shaft shredders, crushers, and multi-stage separation systems, which work in sequence to effectively recover aluminum frames, glass, silicon, plastics, and other valuable materials from end-of-life PV panels. The recycling rate of this equipment can reach greater than or equal to 98% while avoiding the ecological harm typical of conventional disposal practices. Below is the detailed operational workflow of DOING's physical photovoltaic panel recycling machine：

1. Dismantling the Aluminum Frame

The process begins by removing the aluminum frame, which holds significant scrap value. Using specialized aluminum frame dismantling machines, this step can be completed efficiently with minimal labor. Advanced automated systems can perform this task without any manual intervention, ensuring both safety and efficiency.

2. Glass Removal and Primary Crushing

Next, the glass removal unit separates the protective glass covering, while double-shaft shredders and crushers break down the remaining panel components into smaller, manageable pieces. This preparation is crucial for effective material separation in subsequent stages.

3. Multi-stage Separation and Sorting

The crushed materials then undergo a sophisticated separation process through a multi-stage separation system. This technology efficiently segregates and recovers glass, silicon materials, copper, and plastics. The physical separation method ensures high purity levels—aluminum, glass, and plastics can achieve over 98% purity, while copper and silicon powders exceed 98%, making them suitable for direct reuse in manufacturing.

In summary, recycling old photovoltaic panels involves three key stages: dismantling the aluminum frames, removing and crushing the glass and panel components, and finally separating the various materials through advanced sorting technology. This comprehensive approach not only maximizes resource recovery and reuse but also prevents environmental pollution associated with traditional disposal methods.
