What Can I Do With An Old Solar Panel?

Solar photovoltaic panels whose service life is: 20~30 years. The rapid development of photovoltaic energy industry. The whole world will face a large number of waste solar photovoltaic modules scrapped. According to incomplete statistics, by 2050. The amount of used PV module decommissioning is up to 80 million tonnes. Then for the recycling treatment of waste PV modules is crucial. So how to deal with old solar PV panels? It can reduce ecological pollution.

Physical dry method: need to use solar PV panel recycling machine. First through the dismantling machine, remove the aluminium frame, junction box and other components. The aluminium frames can be recycled directly. The junction box can also be sold directly, and the metal part can also be recycled. Then, through the crushing and sorting system, the panels are crushed, ground, screened, gravity sorted and electrostatically sorted. Materials such as glass, silicon powder, plastic and copper powder are separated separately. Silicon can then be purified and recycled.

Pyrolysis treatment method: High-temperature pyrolysis process is adopted. Thermal decomposition of waste solar photovoltaic panels through high-temperature pyrolysis furnace. The organic materials are heated, decomposed and gasified, so that the whole silicon wafer and glass can be separated separately. Achieve thermal decomposition with other inorganic materials. The material obtained after pyrolysis then passes through a cooling system. The valuable metals are recovered. In the pyrolysis process generated in the exhaust gas can be used gas purification device after treatment to meet the discharge standards. Thus reducing the pollution of the environment.

Chemical decomposition method: It is necessary to use chemicals to dissolve the specific components in the photovoltaic panels. Thus, the materials are recovered. Often use acid to dissolve the metal part. The silver, copper and other metals in the panels are dissolved. Valuable metals are then extracted from the solution through methods such as pitting. Often collectively referred to as: wet extraction. However, this recovery process has high treatment costs. And chemical reagents produce wastewater to be properly treated. Avoid secondary pollution of the environment.
