Jiang Yali, a solar analyst at BloombergNEF, said he believes this might to some extent worsen the temporary undersupply of the key solar PV material polysilicon and cause a global supply chain bottleneck.
Polysilicon spot prices surged to $39.20 a kilogram in the week beginning Aug 8, the highest since October 2011, even before this announcement.
"During the period, the exports of raw plastics, electric vehicles and polysilicon have doubled.
The manufacturing output, including approximately 1.14 million metric tons of polysilicon, around 460 GW of wafers, 404 GW of cells and 367 GW of PV modules, contributed to an output value exceeding 1.3 trillion yuan ($182 billion).
The country produced about 233,500 tonnes of polysilicon during the period, surging 93.8 percent from a year earlier, said the Ministry of Industry and Information Technology.
The output of polysilicon wafers expanded 84.3 percent over the previous year to 98.9 gigawatts, the data showed.
China's output of polysilicon, silicon wafers, photovoltaic cells, and modules reached new highs in the first half, with year-on-year growths all exceeding 65 percent.
The output of polysilicon, silicon wafer, cell wafer, and component reached 600,000 tons, 250 gigawatts, 220 gigawatts, and 200 gigawatts, respectively, in the first half of this year, to surge over 60 percent year-on-year for the each, said the paper, citing the China Photovoltaic Industry Association.
During the period, the output growth of polysilicon, silicon wafers, batteries, and components all exceeded 72 percent year-on-year, according to the ministry.
In the March-April period, the output of polysilicon increased by 72.1 percent year-on-year, while that of silicon wafers rose 79.8 percent, according to the ministry.
On the same day, top polysilicon maker Tongwei Co Ltd announced its plan to invest in the construction of a project that will have an annual production capacity of 25 GW solar cells and 20 GW PV modules.
The country is also the world-leading producer of polysilicon, a critical raw material used in solar modules, it said.
The country produced about 176,000 tons of polysilicon during the period, up more than 60 percent from a year earlier, said the Ministry of Industry and Information Technology.
The output of polysilicon wafers expanded 78 percent over the previous year, the data showed.
The output of the major links of the industrial chain, including polysilicon, wafers, cells and modules, all registered year-on-year growth of over 55 percent, according to the Ministry of Industry and Information Technology.
In the first three quarters, the output of four major products — polysilicon, silicon wafers, cells and modules — exceeded last year's total, with year-on-year growth of more than 40 percent, said the association.
More efforts are in the pipeline to ease surging polysilicon prices as China is promoting healthier development of the fast-growing photovoltaic industry, said ministry officials and experts.
More efforts are called for in the output expansion to increase the supply of polysilicon — a key material for PV module manufacturing — rational purchase from downstream buyers to improve supply and demand balance and a crackdown on illegal activities such as price gouging and hoarding products.
With such efforts, experts estimate that production capacity of polysilicon will expand and surpass 2.4 million metric tons in 2023, while the material supply will reach over 1.56 million tons — an equivalent amounting to the manufacturing needs of more than 600-gigawatt PV modules.
The remarks came after the Ministry of Industry and Information Technology (MIIT) released a notice on Sunday and called for strengthened self-initiative inspections and regulations for polysilicon companies.
The price of polysilicon reached 310,000 yuan ($43,400) per ton as of the end of August, up from as high as 247,000 yuan per ton at the end of January, according to the Silicon Industry of China Nonferrous Metals Industry Association.
Calculations from financial news provider Hexun showed that polysilicon has seen 29 rounds of price increases in the first eight months of this year.
The price increase of polysilicon was mainly due to a surge in demand driven by the low-carbon campaign on a global scale and the rapid development of the PV industry, said Lyu Jinbiao, deputy director of the expert commission at the Silicon Industry of China Nonferrous Metals Industry Association.
"The huge demand and the investment spree have driven up prices of polysilicon.
Lyu said that production expansion of polysilicon materials normally takes more than one year — much longer than the expansion of PV power generators of less than six months — causing difficulties to strike a balance between supply and demand.
"Currently, many mid-stream and downstream suppliers are complaining about polysilicon whose prices continue to rise, because upstream suppliers are constantly squeezing profit margins of mid-stream and downstream suppliers.
The half-year output of polysilicon, wafers, cells and modules expanded 53.4 percent, 45.5 percent, 46.6 percent and 54.1 percent year-on-year respectively, according to the Ministry of Industry and Information Technology.
For the last 11 years, China has been topping the world rankings for the output of polysilicon, a key raw material for solar modules.
China produced 505,000 metric tons of polysilicon and 227 GW of silicon wafer during the period.
In addition to large screens, the company started to build a sixth-generation low-temperature polysilicon active-matrix OLED display panel production line in Wuhan, Hubei province, in 2017.
Its annual solar-grade polysilicon output increased from 6,000 metric tons to 8,000 tons after the parent invested $200 million in 2014, while reducing the production cost from $30 per kilogram to less than $10.
As China's first Gen 6 LTPS (low temperature polysilicon) LCD line, the T3 project produces both small and medium-sized panels aimed mainly at smart end devices.
The whole solar value chain from polysilicon to wafers and cell/module production is dominated by Chinese companies.
Polysilicon is abundant in China.
The Guangdong Financial Supervisory Authority released an action plan on Aug 2 to support the listing of carbon emissions rights, electricity, commodity indexes, silicon metals, polysilicon and lithium futures on the Guangzhou Futures Exchange.
Focusing on green and sustainable development, the Guangzhou Futures Exchange will promote the listing of industrial silicon, polysilicon, lithium, rare earth, platinum and palladium and other metal varieties related to new energy, Zhu added.
