The production of photovoltaic module generates a large amount of pollutants

         Photovoltaic cell module production includes several industrial chain segments such as high-purity polysilicon, silicon ingots and wafers, photovoltaic cells, and photovoltaic modules. Reports of related pollution mainly refer to the by-products generated during the production of high-purity polysilicon, the raw material for photovoltaic modules. High-purity polysilicon production primarily uses the modified Siemens method, which converts metallurgical-grade silicon and then reduces it with hydrogen to produce solar-grade polysilicon, while also forming the by-product silicon tetrachloride. Silicon tetrachloride decomposes upon contact with moist air and can cause pollution issues if not handled properly. However, currently, polysilicon production enterprises in China using the modified Siemens method have achieved closed-loop production, recycling by-products like silicon tetrachloride and tail gases, thereby enabling clean production. In December 2010, the state issued the "Polysilicon Industry Access Conditions," stipulating that the recovery rates of silicon tetrachloride, hydrogen chloride, and hydrogen in the reduction tail gas should be no less than 98.5%, 99%, and 99%, respectively. Therefore, mature modified Siemens production technology can fully meet environmental protection requirements and will not cause environmental pollution issues.

     Mangzhong Construction is dedicated to photovoltaic power plant investment, development, design, construction, intelligent operation and maintenance, professional consulting services, and photovoltaic power plant equipment recycling. After a customer expresses installation needs, our engineers will arrive on-site according to the scheduled appointment to conduct professional and efficient on-site surveys, providing you with customized design solutions. To ensure the rigor of later-stage detailed design and further enhance our service quality, we conduct rapid on-site surveys. The design team uses professional tools to accurately measure roof area, assess roof load capacity, surrounding environment, and shading, among other factors. Combining different types of residential roofs and buildings, we scientifically design the optimal solution for you, ensuring maximum returns and long-term stable performance.
