As the core component of solar power generation, the life span of photovoltaic panels is 25 years, because according to the requirements of the T80 standard, the attenuation rate of monocrystalline modules is not higher than 3% in the first year, and the attenuation rate is not higher than 0 in the subsequent years7%, so that 80% efficiency can be maintained for 25 years.
We need to use the method of physical separation to carry out the effective use of photovoltaic panels, the scrapped photovoltaic panels into the shredder for shredding, the shredded materials into the special crusher for crushing, the EVA film and monocrystalline silicon wafers are scattered, the scattered materials enter the aggregate through the induced draft fan, and then after sorting, the silicon is sorted, and the remaining mixed materials then enter the special crusher, and then enter the air flow sorting screen through the closed air filter, and collect the positive metals and plastics through the air flow and vibration. At the same time, the dust generated by the air separator is collected.
Through ** and reuse, we can extract valuable silicon materials, metals and glass from waste photovoltaic panels, reduce the demand for raw materials, and reduce environmental pollution. In order to achieve sustainable development, we need to start from policy, technology, capital and other aspects to promote the in-depth development of waste photovoltaic panel treatment. With the continuous progress of technology and the improvement of public awareness, the prospect of the utilization of waste photovoltaic panels will become more and more broad. We also need to strengthen publicity and education, raise people's awareness of environmental protection, and let everyone become an active participant in the disposal of waste photovoltaic panels.
