Our photovoltaic panel silver extraction equipment is an environmentally friendly, modular, comprehensive recycling system for waste photovoltaic modules. It targets retired photovoltaic panels, defective photovoltaic cells, and battery scraps, employing a composite process of physical sorting, anaerobic pyrolysis, and selective wet silver extraction. Unlike traditional single-process silver extraction equipment, its core advantages include: prioritizing the preservation of high-value silicon material, efficiently extracting electrode silver, and fully recycling glass, aluminum, and copper. This addresses four major pain points in the industry: damaged silicon material, excessive pollution, low recovery rates, and high labor costs.

The raw materials for silver extraction equipment from photovoltaic panels are mainly divided into two categories: 1. Silicon wafers of various sizes obtained from photovoltaic panel recycling equipment. After removing glass, EVA, and metal, they are in the form of whole wafers, half wafers, and small fragments, with residual silver on the surface. 2. Silicon powder. After the photovoltaic panels are crushed/ground, fine powder with a size of approximately 10-20 mesh is obtained. This powder is used as the raw material for silver extraction. The silicon in photovoltaic panels contains a large amount of metallic silver, which needs to be extracted using a chemical wet process.

Through the silver extraction process, waste solar PV panels can be recycled to recover 99% purity crude silver and 99.9%/99.99% high-purity silver as final products.

High Silver Extraction Efficiency and Purity

Silver recovery rate: 98%–99.5%, with almost no loss of silver content. Silver purity can reach 99.9%, and the final product, smelted into silver ingots, meets standards and can be traded directly.

High Silicon Wafer Purity
The equipment not only extracts silver but also completely separates silicon wafers:
Silicon wafers/silicon powder: 6N grade high-purity silicon, which can be recycled for crystal pulling or used as metallurgical raw materials, possessing the highest value.

Mature Technology, Low Energy Consumption, and Environmental Compliance
Mainstream process: Physical crushing + pyrolysis + wet/electrolytic silver extraction, stable and easy to maintain. Energy consumption is only 1/8–1/5 of that of primary silver smelting, saving electricity and reducing costs. Electrolyte/leaching solution is recycled, resulting in less waste liquid and lower reagent costs. Waste gas is centrally treated, meeting emission standards, with no odor or smoke. Cyanide-free and low-acid process, safe, easy to pass environmental impact assessments, and compliant with the Solid Waste Law, WEEE, and EPR.

High degree of automation and low labor costs
Automation rate: 90%–95%; feeding → crushing → pyrolysis → sorting → silver extraction → ingot casting, all on a streamlined production line. Only 2–3 people are needed to manage the entire line, resulting in extremely low labor costs.
