China's photovoltaic glass industry has developed from an import dependence to a global leader, with the current output accounting for more than 90% of the world's total. With the conditional liberalization of the photovoltaic glass production capacity policy, the industry has entered a new round of capacity expansion.
Photovoltaic glass is a kind of packaging material used on photovoltaic modules, which is mainly used to protect the cell from moisture and gas oxidation and corrosion of electrodes; According to different application scenarios and processes, it can be divided into ultra white calendered (embossed) glass and ultra white float glass.
According to the Research Report on the Market Entry of Photovoltaic Glass Products (2022-2027 Edition) of China Research Institute
Development status of photovoltaic glass industry
According to incomplete statistics, since 2021, photovoltaic glass enterprises have announced at least 12 major photovoltaic glass expansion projects, with a total investment of nearly 45 billion yuan. At present, the total production capacity of photovoltaic calendered glass production line under construction in China is about 40000 tons/day. In theory, the new capacity in 2022 should be 15000~20000 tons/day.
In the first half of 2021, with the slowing demand and the release and expectation of new capacity, the price of photovoltaic glass will continue to decline. In September, due to increased energy consumption control and maintenance of soda ash production line, the price increased significantly. At the beginning of December, due to the increase of soda ash inventory and the shipment pressure of natural gas due to sufficient supply, the price of photovoltaic glass has been adjusted so far.
From the perspective of market share, the top six PV glass production capacity in China are Xinyi Solar 32%, Fulaite 22%, Rainbow New Energy 10%, Jinshan Jinxin 9%, China National Building Materials 9%, and CSG 5%. The upstream of photovoltaic glass is soda ash (48%), quartz sand (25%) and dolomite (6%), which account for 79%.
Photovoltaic policy is good for the development of photovoltaic glass industry. China attaches great importance to energy security and sustainable development. With the continuous progress of photovoltaic power generation technology and the continuous reduction of cost, photovoltaic power generation has become the main force. The growth of photovoltaic installed capacity has driven the development of photovoltaic glass industry. In recent years, with the continuous promotion of cost reduction and efficiency improvement in the photovoltaic industry, the economy of photovoltaic power generation has become increasingly prominent, and China's photovoltaic installed capacity has shown a trend of rapid growth.
Development prospect of photovoltaic glass industry
In 2022, China's photovoltaic market may increase to more than 75GW under the huge scale reserve, and the annual average new photovoltaic installed capacity is expected to reach 83-99GW from 2022 to 2025.
The proportion of double glass components has increased year by year. As the double glass module has the advantages of high photoelectric conversion efficiency and slow attenuation, it is expected that the double glass module will gradually become the mainstream of the market during the "Fourteenth Five Year Plan" period, which also means that the demand for photovoltaic glass will increase significantly. The proportion of large-sized silicon chips has gradually increased. At present, there are many silicon wafer sizes on the market, mainly smaller than 166mm, 166mm, 182mm, 210mm, etc. At present, silicon chips smaller than 166mm are the mainstream in the market. However, since large size silicon chips can reduce the manufacturing cost of silicon chips, it is expected that silicon chips will develop towards large size in the future. The larger the silicon chip size, the more photovoltaic glass will be needed.
