Technology behind Photovoltaic Panel Recycling Systems

With the rapid expansion of the global photovoltaic industry, a large number of solar panels will become obsolete in the coming decades. The safe and efficient disposal of these discarded photovoltaic panels, which contain glass, aluminum frames, silicon wafers, and trace amounts of hazardous materials, is not only a matter of environmental protection but also directly impacts resource recycling. Photovoltaic panel recycling systems have emerged to address this issue, combining advanced mechanical and separation technologies to provide solid support for sustainable energy development.

Photovoltaic panel recycling systems typically consist of multiple processes and supporting equipment designed to maximize resource recovery and ensure environmental friendliness throughout the entire process. Typical processes include:

Disassembly and pre-processing equipment: Automated disassembly machines remove junction boxes and aluminum frames, preparing the system for subsequent processing.

Crushing and sorting systems: A crusher cuts the panels into small pieces. Screening, gravity separation, and magnetic separation equipment then gradually separate the glass, silicon wafers, and metal components.

Heat treatment and stripping technology: The EVA film and cell wafers are separated in a temperature-controlled pyrolysis furnace, preserving the high recycling value of the silicon wafers.

Electrostatic separation and fine recovery equipment: Used to extract precious metals such as aluminum, copper, and silver, while also ensuring high-purity recovery of plastics and glass.

Exhaust gas treatment and environmental protection system: The complete equipment suite is equipped with exhaust gas purification and dust removal facilities to ensure pollution-free emissions during the recycling process, complying with environmental standards.

The coordinated operation of these core equipment significantly increases the recycling rate of photovoltaic panels, with glass and metal recovery rates exceeding 95%, while preserving the reuse value of silicon wafers.

The photovoltaic panel recycling system is more than just a tool for processing waste components; it also provides crucial technical support for promoting a circular economy and green manufacturing. Through efficient mechanical separation and environmentally friendly processing, it not only reduces landfill pressure and environmental risks, but also allows valuable resources such as aluminum, silver, and silicon to be re-integrated into the production chain, creating significant economic benefits for enterprises.
