The off-season of photovoltaic industry is not light, and the prices of related products in the industrial chain also rise. According to the data of China photovoltaic Association, the silicon material increased by 224% in 2021. Although it decreased at the end of the year, it still increased by 177% compared with the beginning of the year. Since this year, under the high demand, the price of silicon material has continued to rise. On March 16, the silicon branch of China Nonferrous Metals Industry Association announced the latest silicon material price. The average transaction price rose for nine consecutive weeks, with the latest increase of about 0.5%. Industry insiders believe that the progress of silicon material production expansion has accelerated, but it is still in the climbing period of new production capacity, and the overall supply shortage may be alleviated in the second half of the year.
