As a major force of clean energy, solar power generation has developed rapidly in recent years. However, there is still no clear and unified answer on how to dispose of solar panels after they are scrapped.

　　Forbes.com pointed out that the toxicity of solar panels has a more serious impact on the environment than other garbage. At present, solar cells are mainly two types of technical routes, crystalline silicon cells and thin-film cells. The former is mostly glass, but still contains traces of toxic compounds such as cadmium and lead; the latter is cadmium telluride, which is toxic and carcinogenic. They will cause harm to the public environment and human health if they are piled up in the garbage dump for a long time.

　　Some countries have categorized solar panels as hazardous waste, which can only be transported at designated times and routes, plus unforeseen costs such as dismantling, storage, and professional treatment. The overall scrap price is not cheap, which leads the recycling industry to fundamentally There is no profit, so they are naturally unwilling to recycle solar panels.

　　The International Renewable Energy Agency (IRENA) pointed out that only with a clear policy support framework can a new industry for the recycling and reuse of "wind and solar power" equipment be born, thereby promoting the creation of considerable economic value.

　　It is understood that at present, European solar panel manufacturers have begun to establish their own scrap business, and special allocations for the recycling and subsequent processing of discarded solar panels.

　　The United States has not paid much attention to this issue so far. Even if the "Resource Protection and Recycling Act" was revised, it still did not include obsolete solar panels.

　　US Environmental Protection Agency data believes that the amount of "solar e-waste" is negligible. In this regard, some analysts warned that with the rapid development of the solar energy industry, the scrapping rate of solar panels in the future will be faster than expected and larger in scale.

　　Countries around the world should formulate relevant recycling incentive policies and measures, and at the same time develop sufficient recycling infrastructure. Only by creating a profitable recycling market can the cleanliness and sustainability of the solar energy industry be best reflected.

　　Lithium-ion battery (LIB) has become the main energy storage solution in modern social life. Among them, lithium iron phosphate batteries are a perfect replacement for lead-acid batteries, and they are the first choice for grid-connected peak shaving, off-grid energy storage, photovoltaic energy storage, UPS, data center and other industries.

　　Solar power generation system with lithium battery energy storage system is a very promising clean energy.
