Product Description

With the widespread application of solar panels, their service life (approximately 25 years) is nearing its end, and the recycling management of end-of-life solar panels has become a new challenge for the industry. To address this challenge, we have developed a fully automated photovoltaic module pyrolysis recycling production line. This recycling line, through the integration of intelligent automation and pyrolysis technology, can efficiently recover pure silicon, glass, and copper, achieving an industry-leading 99% material purity recovery rate. Furthermore, silicon wafers are processed using our silver extraction technology to obtain silver with a purity of 99.99%. The recycling line is designed for stable and continuous operation, suitable for large-scale processing of photovoltaic modules of various sizes and generations. It is also equipped with eco-friendly processing systems that fully comply with all environmental standards.

Main Components Of Solar Panels

Advantages and recycling value of solar panel pyrolysis

The core of solar panel pyrolysis is to process photovoltaic modules in a high-temperature environment. This process decomposes internal organic binders, plastic layers, and other composite materials, releasing high-value raw materials such as silicon wafers, glass, and aluminum frames. The upgraded automated recycling production line achieves intelligent continuous operation, maximizing efficiency and recycling purity. After pyrolysis, the purity of the recycled materials can reach 99%, requiring almost no complex sorting processes. This not only reduces labor and energy consumption but also significantly simplifies subsequent processing. Compared to traditional mechanical crushing or chemical leaching methods, pyrolysis offers several advantages: 1. High integrity and high recovery rate: Maintains the physical morphology and structural integrity of crystalline silicon wafers and ultra-white glass to the greatest extent. 2. Green and zero-additive: A fully physical-thermal process, requiring no chemical reagents, eliminating secondary wastewater pollution at the source. 3. Automated control system (PLC/SCADA): Continuously monitors temperature, gas emissions, and energy consumption to ensure the stability and safety of the entire production line, making production more controllable and reliable. Meanwhile, integrated waste gas purification and emission systems (such as activated carbon adsorption and scrubbing towers) effectively treat gases generated during high-temperature decomposition, fully complying with environmental standards.

This is not merely a technological solution, but a key driver of sustainable development in the photovoltaic industry. For investors, equipment upgrades mean higher processing capacity and better material recycling purity, resulting in higher economic returns. Although the initial investment is relatively large, the increasing number of waste photovoltaic modules is driving sustained market demand for recyclable materials such as high-purity silicon wafers, recycled glass, and aluminum. This trend will significantly shorten the investment payback period. Furthermore, by adopting advanced recycling equipment, companies can not only enhance their competitiveness but also establish a positive social image under increasingly stringent environmental policies.

Solar Panel Pyrolysis Recycling Plant Working Process

The solar panel pyrolysis recycling system employs a fully automated workflow to process waste photovoltaic modules. First, a robot feeds the modules, then intelligently removes the junction boxes and aluminum frames. Its core patented pyrolysis technology decomposes EVA and backsheet materials under low-oxygen or anaerobic conditions, effectively releasing the internal components. Subsequent multi-stage physical separation precisely sorts silicon wafers, glass, metals, and other materials into independent output streams, achieving high recycling efficiency and stable continuous operation, suitable for large-scale photovoltaic module recycling.

Part 1: Fully Automated Robotic Feeding System
A Fully automated industrial robots are used to pick up and feed waste photovoltaic (PV) modules into the system.

Part 2: Junction Box Removal
A fully automated solar panel junction box removal machine equipped with optical sensing and visual recognition systems to precisely locate and automatically remove junction boxes.

Part 3: Aluminum Frame Removal
A fully automated solar panel aluminum frame removal machine efficiently detaches the aluminum frames from the PV modules.

Part 4: High-Temperature Pyrolysis Separation
Pre-treated PV modules are fed into a specialized solar panel pyrolysis tunnel furnace. The patented pyrolysis process operates under low-oxygen or oxygen-free conditions, completely decomposing the EVA encapsulant and backsheet materials.

Part 5: Multi-Stage Separation System
Using our proprietary solar panel pyrolysis sorting equipment, the material discharged from the furnace undergoes physical vibration and drum sorting to first separate large pieces of clean glass. Subsequently, air classifiers and electrostatic separators are used to precisely separate silicon wafers, copper ribbons (solder strips), and precious metals like silver based on density differences.

Part 6: Silver Extraction from Silicon Wafers
A silver stripping machine is used to extract silver (at 99.99% purity) from the silicon wafers.

Final Products: Junction box, aluminum frame, glass, silicon wafer, copper wire, silver

Solar Panel Pyrolysis Recycling Plant Features & Advantages

1. Fully Automated Production Line Operation: The core advantages of fully automated pyrolysis technology lie in achieving lossless recovery, extremely high purity, high automation, and energy self-sufficiency. This significantly reduces labor costs and accelerates processing speed, thereby improving overall production efficiency.

2. Self-Recycling of Pyrolysis Gases: During the pyrolysis process, EVA film and backsheet generate combustible organic gases (such as hydrocarbons). Modern factories collect and purify these waste gases, then reintroduce them into the tunnel furnace burner as fuel.

3. Environmentally Friendly Physical Process: The entire system operates using a purely physical method, seamlessly separating the originally tightly bonded structure through the key step of “pyrolysis.”

4. Strict Control System for Exhaust Gas and Byproducts: Equipped with highly efficient flue gas purification devices (such as activated carbon adsorption, regenerative thermal oxidizer (RTO), and dust removal devices), the system rigorously captures harmful gases such as hydrogen fluoride (HF) that may be released when the backsheet is heated, ensuring compliance with environmental standards.

5. Extremely High Resource Recovery Rate and Purity (High Economic Value): Solar Cells Retain Intact: Traditional physical crushing methods mix silicon, silver, copper, and glass together, forming highly difficult-to-separate “electronic waste powder.” Pyrolysis allows for the complete separation of solar cells, facilitating subsequent targeted extraction of high-purity silver (Ag) and solar-grade silicon (Si) through fine chemical metallurgy, maximizing economic value.

6. High-Value Glass Recycling: The tempered glass obtained after pyrolysis has no EVA residue on its surface and is extremely pure. It can be directly recycled into high-transparency photovoltaic glass, avoiding the “low-value” predicament of being downgraded for use as building aggregate.

7. Truly Achieves “Zero Cross-Contamination” of Materials: Physical crushing methods easily allow fluorine in the backsheet and sulfur in the adhesive film to contaminate the metals and silicon. Pyrolysis removes organic matter through gasification, ensuring the surface cleanliness of the metals (copper, silver) and silicon materials, significantly reducing the difficulty of downstream refining and the consumption of chemical reagents.

8. Excellent energy-saving and emission-reduction benefits (carbon footprint advantage): Compared to dissolving EVA with all chemical solvents, the pyrolysis process does not generate large amounts of toxic chemical wastewater, ensuring compliance with environmental standards.

9. Powerful comprehensive throughput and adaptability: The tunnel furnace design possesses strong continuity, capable of processing crystalline silicon solar panels of different sizes, with varying power degradation levels, and even those with partially cracked surfaces. Combined with front-end pretreatment equipment, it enables 24-hour uninterrupted large-scale industrial processing.
