With the growing global demand for clean energy, solar photovoltaic (PV) power generation systems are widely used. However, PV modules will gradually enter the end-of-life period after a service life of 20 to 25 years, bringing a large number of used solar panels. If not handled properly, it will not only cause waste of resources, but also may trigger environmental pollution. Therefore, it is particularly important to establish an efficient and environmentally friendly PV module recycling system. And professional recycling equipment is the key to achieve the goal of resource reuse and environmental protection.
Equipment for the Recycling of Solar and Photovoltaic Panels
The recycling process of solar PV panels mainly includes three stages: crushing, separation and purification. First of all, the crushing equipment carries out preliminary crushing of the whole PV module, so that the glass, silicon wafers, aluminum frames and so on can be separated. Subsequently, metal, glass and silicon materials are further classified efficiently through advanced sorting technologies, such as magnetic separation, wind separation and electrostatic separation. Among them, the application of pyrolysis technology is able to remove the EVA encapsulation layer from the module, leaving the silicon wafers intact and creating favorable conditions for subsequent purification and remanufacturing. The whole process not only realizes a high recovery rate of raw materials, but also effectively reduces energy consumption and carbon emissions.
At present, there are a variety of special equipment for solar panel recycling in the market, covering from crusher, pyrolysis furnace, magnetic separator to fully automatic PV recycling production line, etc., which are suitable for recycling enterprises with different scales and needs. For start-up recycling enterprises or regional recycling stations, the integrated all-in-one machine is the ideal choice, which is compact and easy to operate; while for large-scale processing centers, modular production lines are available to achieve higher capacity and automation levels. When selecting equipment, it should be scientifically configured in conjunction with treatment capacity, PV panel type, environmental standards and recyclables reuse plans, so as to achieve sustainable development and good economic benefits at the same time.
