Can end-of-life solar photovoltaic panels be recycled
The service life of solar panels is 20 to 30 years. With the great development of the global solar energy manufacturing industry, there will be a wave of "scrapping" of photovoltaic panels all over the world. According to relevant statistics, by 2050, waste photovoltaic modules will even reach 80 million tons. Therefore, it is very important to strengthen the recycling of waste photovoltaic modules.
At present, there are three mainstream solid waste treatment methods for waste photovoltaic modules: one is to downgrade or use after repair; the other is to remove the frame and junction box and use it as filler in the construction field or incinerate as garbage; the third is to recycle and reuse . Among them, the recycling of waste photovoltaic modules is considered the most scientific and effective method.
Solar panel material composition
In fact, many materials used to make battery panels can still be recycled. For example, the core material crystalline silicon can be reused in the heavy metal industry, glass panels can be sent to the glass manufacturing industry, aluminum frames can be sent to aluminum refineries, cables, After being crushed, joints and the like can be reused in the form of copper beads, and waste plastics and the like can be used as fuel... So as long as they are handled properly, there is no need to worry too much about the waste of solar panels that will bring new energy to the environment. Pollution, or waste of resources, the photovoltaic panel recycling equipment developed now can recycle and reuse photovoltaic panels very well, and will not cause pollution. The following is a formal introduction to this specific process:
End-of-life solar panel recycling process
The specific process of photovoltaic panel recycling and processing equipment: first, remove the glass on the photovoltaic panel; second, disassemble, remove the backplane and wires; third, break the components and remove the outer tempered glass; fourth, carry out Pyrolysis, the main purpose of this step is to dissolve EVA; the next step is extraction, to remove valuable metals and silicon materials from the components. It has been officially put into operation and can dismantle, sort, process and recycle 95% of the materials in crystalline silicon photovoltaic panels: 2/3 of the glass is recycled into broken glass and sent to the glass factory; the aluminum frame is It is sent to aluminum refineries; waste plastics can be used as fuel in cement plants; the recovered silicon can be reused in the precious metals industry; and the remaining cables and connectors are crushed and sold as copper beads.
The solar panel recycling equipment developed and produced by SUNY GROUP sorts and disassembles decommissioned components, and recycles reusable materials such as silicon, silver, copper, aluminum, etc., forming a comprehensive recovery rate of more than 95%. Through the recycling of component materials Reuse reduces the mining of primary resources and reduces the energy consumption of resource extraction, thereby effectively alleviating the pressure on the ecological environment and reducing the energy consumption of the entire industrial chain. It also protects the environment and avoids waste of resources.
