Breakthrough in solar panel recycling technology research in photovoltaic industry

China State Grid Qinghai Electric Power Company introduced on the 3rd that the company has made new breakthroughs in the research of solar panel recycling technology in the photovoltaic industry, achieving large-scale, low energy consumption, low-cost resource treatment and recycling of waste solar panels, which promotes new energy power generation. The healthy and sustainable development of industry has positive significance.

In recent years, China ’s new and cumulative installed photovoltaic capacity is the first in the world. Qinghai has relied on location advantages to build the entire industrial chain of the photovoltaic industry. It has become the most concentrated area of ​​large-scale photovoltaic power grid integration in the world. How can it be harmless and resourceful Handling and recycling solar panels has become a hot issue of concern to industry and environmental protection.

According to the Electric Power Research Institute of China State Grid Qinghai Electric Power Company, the waste solar panel recycling method is prone to generate waste liquid and waste gas, cannot effectively separate valuable components, and poses a threat to the dismantled ecosystem and residents ’health.

It is understood that the service life of solar panels is 20 to 30 years, and it is predicted that by 2050, China's waste photovoltaic modules will reach about 20 million tons.

According to the Electric Power Research Institute of China State Grid Qinghai Electric Power Company, the vast majority of discarded solar panels and photovoltaic modules can be used as recycled materials, with considerable recycling value, and the need for environmentally friendly and efficient photovoltaic module treatment technology and equipment .

According to reports, through empirical evidence, this technology can realize the recycling of various types of materials such as glass, metal, silicon powder and other materials after the solar panel is dissociated. At the same time, it has less material waste and crushing effect than traditional mechanical disassembly. Good and low processing costs.

According to the Electric Power Research Institute of China State Grid Qinghai Electric Power Company, this technology has the characteristics of low environmental pollution, low energy consumption and high economic returns, and has a broad application space, which can provide new solutions for the environmentally friendly recycling of waste solar panels in China. , Is conducive to promoting the recycling of solar panels in China.
