High-Efficiency Solar Panel Recycling Machinery from China

As the number of decommissioned photovoltaic modules continues to rise, solar panel recycling equipment is gradually shifting from simple dismantling towards automation, large-scale operations, and high recovery rates. The photovoltaic panel recycling production line developed by SUNY GROUP, featuring an automated feeding system with robotic arms, can effectively improve processing efficiency, reduce labour costs, and ensure the stable sorting and recovery of aluminium frames, glass, silicon powder, and plastic materials.

Automated feeding system enhances overall line efficiency

In traditional solar panel recycling processes, manual handling and feeding have always been critical factors affecting efficiency and safety. This equipment utilises a robotic arm-based automatic gripping and feeding system, which can continuously convey waste solar panels, reducing the risks associated with manual contact with broken glass and sharp frame edges, whilst ensuring a more stable feeding rhythm.

Depending on the equipment model, the production line offers two processing capacity options: 50–60 panels per hour and 1,000–1,500 kg per hour, making it suitable for both small and medium-sized recycling centres and large-scale photovoltaic module processing projects. The total power range of the equipment is 240 kW–390 kW, capable of meeting continuous production requirements.

Compared to conventional manual feeding methods, the greatest advantage of automated feeding lies not merely in labour savings, but in the reduction of material jams, misalignment, and equipment idling, which has a significant impact on the stability of subsequent crushing and sorting processes.

The multi-stage sorting structure enables efficient material recovery

The entire solar panel recycling line primarily comprises processes such as frame removal, crushing, pulverisation, air classification, and material recovery. The equipment first dismantles the frames of the photovoltaic modules to separate the aluminium; the modules then enter the crushing system for preliminary processing of the glass and backsheet; finally, the fine crushing and air classification systems further separate materials such as copper, plastic, and silicon powder.

Due to the complex internal material structure of photovoltaic modules, simple crushing alone rarely achieves high purity; therefore, the production line typically employs a multi-stage sorting process to improve the recovery rates of different materials. In particular, the separation of glass and lightweight plastics places high demands on airflow control and discharge uniformity; this is also the primary reason why the sorting performance of many lower-specification machines becomes unstable over time.

In actual recycling operations, aluminium frames and glass usually account for the majority of the module’s total weight, whilst silicon powder and metallic materials directly impact the recovery value; consequently, a stable sorting system is more important than simply increasing the crushing speed.

Equipment is better suited to continuous recycling projects

In terms of equipment dimensions, large models can reach lengths of over 10 metres, making them typical examples of continuous industrial recycling equipment. Such equipment is better suited to long-term, stable operation rather than short-term, intermittent production.

For the photovoltaic recycling industry, future competition will focus not merely on ‘whether recycling is possible’, but on energy consumption per unit, material purity, and labour cost control. The higher the level of automation, the more pronounced the operational advantages will be in the long term. Particularly against the backdrop of rising labour costs overseas, solar panel recycling equipment equipped with robotic automatic feeding systems has gradually become a key configuration for large-scale recycling projects.
