Henan Doing - Model DY-500,DY-1000 -What are the steps in solar panel recycling?

As the global shift toward renewable energy accelerates, the lifecycle management of solar panels has become a critical environmental and economic concern. At Henan Doing Holdings Co., Ltd., we are pioneering sustainable solutions for solar panel recycling, ensuring that every decommissioned panel contributes to a circular economy. Our cutting-edge technology and global expertise make us a trusted partner in the green energy transition.

Here are five specific steps for DOING's solar panel recycling equipment to process used solar panels:

1. Dismantling the Aluminum Frame

The recycling process begins with the removal of the aluminum frame, which holds significant scrap value. Using our specialized aluminum frame dismantling machines, this step is completed efficiently and safely with minimal manual intervention. The automated system ensures high recovery rates while reducing labor costs and operational risks.

2. Glass Removal and Primary Crushing

Next, the glass removal unit carefully separates the protective glass covering. The remaining panel components are then processed through double-shaft shredders and crushers, breaking them down into smaller, uniform fragments. This step is crucial for preparing materials for efficient separation in the following stages.

3. Multi-stage Separation and Sorting

The crushed materials undergo a sophisticated multi-stage separation process using vibrating screens, air classifiers, and other advanced sorting equipment. This system efficiently segregates glass, silicon materials, copper, and plastics with high precision. Through physical separation methods, materials such as aluminum, glass, and plastics can achieve over 98% purity, while copper and silicon powders also exceed 98% purity—making them suitable for direct reuse in manufacturing.

4. Eco-Friendly Disposal and Reintegration

Recovered glass and plastics are repurposed for construction materials, while any remaining waste is disposed of responsibly. This ensures that the entire process aligns with circular economy principles, minimizing landfill use and environmental pollution.

In summary, recycling old photovoltaic panels involves five key stages: dismantling the aluminum frames, removing and crushing the glass and panel components, separating various materials through multi-stage sorting, chemically recovering high-value metals, and responsibly reintegrating or disposing of residual materials. This comprehensive approach not only maximizes resource recovery and reuse but also prevents environmental pollution associated with traditional disposal methods.

In addition to the equipment advantages, DOING can provide fully customized solutions tailored to your processing capacity, from small-scale operations to large industrial old photovoltaic panel recycling plants. Our service extends beyond equipment supply – we assist in obtaining necessary certificates and compliance documentation for your market. With over 14 years of experience in exporting and installing recycling systems worldwide, we have successfully established projects across more than 120 countries. We have a professional technical service team that can serve customers around the world and ensure efficient support, including major markets such as India, China, the United States, Poland, and the United Kingdom. Additionally, we offer engineer dispatch for on-site installation, commissioning, and operational training to guarantee smooth project implementation and optimal performance.

At Henan Doing Holdings, we turn solar panel waste into valuable resources. By maximizing recovery rates and minimizing environmental impact, we help businesses meet sustainability goals while creating economic value. Join us in building a cleaner, greener future.
