Solar Panel Recycling Machine For Sale

In today’s society, the global pursuit of clean energy is gaining momentum. With environmental pollution becoming increasingly severe and traditional energy sources gradually depleting, solar energy—as a clean, renewable resource—has garnered widespread attention and promotion. The photovoltaic industry has experienced rapid development, leading to the extensive installation of solar photovoltaic panels worldwide. Over time, the earliest batches of these panels have reached the end of their operational lifespan. The recycling and processing of end-of-life photovoltaic panels have thus become a critical and highly challenging issue. Highly efficient, environmentally friendly, and energy-saving solar panel recycling machine is key to achieving a green closed-loop system and resource circulation within the photovoltaic industry.

Introduction to Solar Panel Recycling Machine

The equipment employs a modular design, enabling integrated processing throughout the entire disassembly, crushing, sorting, and recovery workflow. Precision equipment first cuts and separates the aluminium frames and glass from the panels. Controlled-speed crushing equipment then reduces the photovoltaic components into fine particles. This is followed by airflow separation and high-voltage electrostatic separation technologies to precisely isolate valuable materials such as silicon wafers, plastics, and copper wires. The core material recovery rate of the entire system exceeds 98%. The purity of the separated silicon powder meets photovoltaic panel production standards, enabling its reuse in manufacturing new solar panels. The entire production line operates in a fully enclosed process. Paired with high-efficiency pulse dust collectors, it eliminates dust leakage. Crushing collection efficiency reaches 99.9%. The entire process employs dry physical-mechanical methods, requiring no chemical additives. Consequently, it avoids water pollution and consumption, preventing secondary contamination. It fully complies with environmental standards and supports continuous automated operation. The PLC intelligent control system enables real-time parameter adjustment.

Solar Photovoltaic Panel Recycling Process Flow

Aluminium Frame Disassembly

Initial inspection and pre-treatment of waste PV modules. Removal of junction boxes and aluminium frames via dedicated disassembly equipment. Professional separation of aluminium frames from laminated substrates. Recovered aluminium frames exhibit high material purity. High economic value. After simple processing, it can be directly reused as recycled aluminium material. Equipment in this stage features high efficiency and energy savings, ensuring complete frame recovery.

Glass Removal

The laminate (composite of glass, EVA, cells, and backsheet) after frame removal presents the primary processing challenge. This stage typically employs specialised solar panel deglazing machinery. Glass is removed from the panels with an efficiency exceeding 96%.

Crushing and Sorting

• Shredding: Post-glass removal, panels are shredded into 3-4cm fragments using shredders. This facilitates subsequent pulverisation and screening.
• Pulverisation: Materials undergo further crushing in the fine grinding stage. This separates distinct layers (glass, silicon powder, plastics, metals).
• Sorting:Materials are progressively separated using a series of screening equipment based on physical properties (density, particle size, conductivity, magnetic properties, etc.).
• Air-flow Sorting:Utilises air currents and gravity to separate lightweight plastics from heavier glass and metal particles.
• Vibratory Sorting:Classifies materials by particle size, creating optimal conditions for subsequent sorting stages.
• Electrostatic separation: Exploits material conductivity differences. Under high-voltage electric fields, conductive metal particles (silver, copper, etc.) are efficiently separated from non-conductive silicon powder and proportion particles.
• Through the combined application of these physical separation techniques, relatively high-purity valuable materials—including glass particles, silicon powder, plastics, proportion particles, and copper—are ultimately obtained. The entire process requires no chemical reagents, constituting an environmentally friendly green treatment method.

Material Analysis of Solar PV Panel Recycling Machine

Materials obtained through crushing and sorting can enter corresponding resource recovery channels:
Silicon Powder: Post-sorting, silicon powder undergoes further purification. It serves as raw material for metallurgical industries or other silicon-based materials.
Glass: Utilised as raw material for construction insulation, foam glass, or new glass production.
Plastics: Processed plastics may be utilised in the production of lower-specification plastic goods.
Metals: Undergo further pyrometallurgical or hydrometallurgical purification processes. This yields high-value copper and silver.

The complete photovoltaic panel recycling system eliminates the risk of secondary environmental pollution while safeguarding the quality of valuable resources. This equipment enables a closed-loop “resource regeneration” process, delivering tangible economic benefits to enterprises. Crucially, it facilitates the green development of the photovoltaic industry throughout its entire lifecycle, providing practical technological support for achieving the dual carbon goals.
