Qunfeng Heavy Industry PV Panel Recycling Process Technology


Crystalline Silicon Panel Recycling

- Crystalline silicon photovoltaic panels consist of one chemical substance: crystalline silicon.

- Crystalline silicon technology is the most widely used technology today: it accounts for about 80% of panels due to its robustness and high quality performance.

- Recycling Process: Crushing or Layering

The various stages of the crushing process:

1. Receiving and unloading at the processing center

2. Pre-disassembly

3. Crushing of panels, screening and refining of chips

4. Airstream screening

5. Density or flotation separation

6. Eddy current screening

Qunfeng Heavy Industries' recycling capabilities


- State-of-the-art technology: we have selected innovative technologies to create efficient recycling processes. Different photovoltaic technologies require different treatment equipment. Waste photovoltaic panels are a fast-growing resource, with first-generation panels now reaching the end of their useful life. Our specialized and targeted solutions ensure that these panels will be recycled according to the strictest standards. We invest significant resources in research and development of innovative, environmentally friendly and value-creating solutions.

- Reducing environmental impact: We apply the proximity principle and dispose of used photovoltaic panels at the nearest location. To support the implementation of the circular economy, we reinvest recycled materials in our supply chain. We analyze the environmental impact of each process and minimize the associated impact.

- Controlling costs: Our goal is to obtain optimal recycling quality and purity, harmonizing environmental and economic development. The purity of the material obtained at the end of the recycling process is directly related to its market value. Revenues from recycled materials are an integral part of the economic benefits, covering a significant part of the costs associated with collection and disposal.

Intelligent PV panel recycling system


Qunfeng Heavy Industry|New Photovoltaic Recycling Technology (III)


The PV Panel Intelligent Recycling System is a fully automated solar panel recycling solution using artificial intelligence and machine learning technologies to achieve 100% recycling rate, 99% carbon reduction and 95% cost savings. The solution utilizes visual AI to identify solar panels and a physical disassembly system to separate the various materials while ensuring the quantity and quality of recycled materials.


Benefits of the Intelligent PV Panel Recycling System


Optimized to improve efficiency

Designed for environmentally friendly and economical solar PV panel recycling, the PV Panel Smart Recycling System is different from any other solution

- Compact dimensions in a 40-foot container size for easy deployment and expansion

- High throughput averaging one panel per minute Fully automated with no human intervention 10,000 tons per year

- Low cost of 5 kWh

Requires no materials, no water, and only 5 kWh to treat each PV panel. Saves costs and reduces carbon emissions


Sustainable

Fully recycled

The Smart Recycling System for PV panels provides a sustainable recycling solution for used PV panels that recycles all materials, including solar cells, adhesives (EVA, etc.), backsheets (fluoropolymer resin, PVDF, etc.), aluminum frames, glass, and junction boxes, without mixing pollution. The solution retains the value of the recycled materials and facilitates downstream reuse, contributing to the circular economy.

100% VS 80%

The field of WEEE recycling requires 80% of the material to be recovered, and most technologies can easily achieve this goal. However, the remaining 20% of unrecycled materials cause the greatest pollution. The Intelligent Recycling System for Photovoltaic Panels recycles all materials without any material loss or pollution, contributing to environmental sustainability.


Eco-friendly

No chemicals and no heat

The PV Panel Smart Recycling System solves the shortcomings of existing methods by using physical techniques instead of chemicals, heat or landfills. It offers the most environmentally friendly solution and complies with regulations that prohibit the use of chemicals or heating methods.


Automation

The Future of Recycling

The Smart Recycling System for PV panels is committed to sustainability and achieving net-zero carbon emissions. It starts by increasing efficiency through automation, integrating visual AI, automated machine learning and OTA to automatically recognize, adjust, self-learn and process panel recycling.

- Visual AI: recognizes PV panels and initiates automated operations

- Automated machine learning: automatically adjusts the feed to ensure recycling quality

- OTA: update the latest and optimized solutions from the cloud


Low cost and high yield

The PV panel smart recycling system realizes recycling profitability through automation, artificial intelligence, etc. 100% recycling, upgraded recycling process and carbon reduction yield more.
