Solar panels convert solar energy into electricity, effectively reducing dependence on fossil fuels and contributing to environmental protection and sustainable development. But do you know that the lifespan of solar panels is 25~30 years, and the working efficiency will decline after 25 years. With the rapid development of the solar industry, more and more panels are produced and used, we can not escape the problem of how to deal with the used panels. At present, the main treatment of waste battery panels is recycling, reuse and landfill disposal.
At present, the recycling rate of solar panels is still low, the used panels can be handed over to the panel manufacturers or relevant professional organizations for recycling, and the disassembled processing can get glass, plastic and metal, which will be re-invested into the production of new panels to realize the sustainable use of resources.
As long as the used battery panels do not cause environmental hazards, reuse is a viable option. Old battery panels may not be suitable for producing electricity, but they can be used for certain small power supply devices. For example, home backup power, outdoor yard and street lighting.
Due to the inadequacy of the current battery panel recycling process and the high cost of recycling, landfill is one of the simplest and cheapest ways to dispose of them. Before formal landfill, it needs to be professionally evaluated and confirmed to be safe for disposal. However, there are many problems in landfill treatment, which occupy and jeopardize land resources, and the toxic and harmful substances produced in the process of degradation pollute water resources and air, which seriously jeopardize the ecological environment.
1. Hazardous materials handling. Battery plates contain heavy metal elements such as cadmium and lead, which can seriously jeopardize human health and the natural environment if they are not effectively treated.
2. Inadequate infrastructures for recycling. The current battery board recycling and treatment process is at the beginning stage, and there are problems such as immature recycling and treatment technology, unsatisfactory treatment effect and imperfect treatment facilities. These problems seriously affect the current process and efficiency of battery panel recycling.
3. High recycling cost. The process of recycling panels requires many factors to be considered, resulting in recycling costs that are usually higher than the cost of manufacturing new panels, which means that many solar panels are directly discarded or landfilled instead of being recycled.
4. Lack of recycling awareness among the general public. The general public, faced with used panels, do not know that they contain hazardous substances, which reduces the importance of used panels, and panels that are not effectively disposed of will jeopardize the natural environment.
Effective recycling of used battery panels is conducive to the realization of environmental protection and sustainable development, but the current battery panel disposal is facing a very serious challenge, which requires the joint efforts of the government, manufacturers and consumers.
