On July 26, the official website of Longji green energy (601012.sh), the leader of photovoltaic silicon chips, updated the quotation of p-type monocrystalline silicon chips. Compared with the quotation on June 30, the price of 182mm silicon wafer increased by 0.24 yuan / piece, or 3.3%; The prices of 166mm silicon wafer and 158.75mm silicon wafer increased by 0.25 yuan / piece, or 4.1% and 4.3% respectively. In addition, in this quotation, Longji will increase the thickness of 182mm silicon wafer from 160 μ M adjusted to 155 μ m。< Br > < div class= "contheight" > < /div> this is the latest scene of the continuous price rise in the photovoltaic industry chain since last year. From the upstream to the midstream, the photovoltaic industry chain is divided into four links: silicon material, silicon wafer, battery slice and module, and the downstream is the power station end. Within a short week, the industry “Rose” sound linkage< Br > < div class= "contheight" > < / div > on July 21, TCL Zhonghuan (002129.sz), another silicon chip leader, took the lead in announcing a comprehensive increase in product prices. The latest p-type and n-type monocrystalline silicon chip prices released by Zhonghuan showed that the overall price of silicon chips of different sizes increased by 0.24-0.41 yuan / chip compared with the previous period, with an increase of about 4%< Br > < div class= "contheight" > < / div > on July 25, Tongwei Solar’s official website (600438.sh) announced the latest pricing of single crystal solar cells. The prices of cells of different sizes increased by 4-5 points / watt, or 3.1% – 4.1%< Br > < div class= "contheight" > < /div> the upstream increases in turns, which will directly push up the cost of photovoltaic modules. It is estimated that the price of single crystal components will comprehensively exceed 2.1 yuan / watt, which is the ultimate challenge for power station developers< Br > < div class= "contheight" > < / div > the source of the price rise in the whole industry is the continuous soaring price of silicon materials: since 2021, due to the mismatch between supply and demand in all links of the photovoltaic industry chain, the price of polysilicon materials has soared all the way. As of last week’s tracking data, the maximum price of silicon material has reached 310000 yuan / ton, up 250% compared with the beginning of 2021, hitting a new high in recent 10 years< Br > < div class= "contheight" > < / div > some photovoltaic module manufacturers have been unable to bear the heavy burden of price rise and have stopped production. At the industry forum held recently, Wang Bohua, honorary chairman of the China Photovoltaic Industry Association, said that in June this year, the bidding volume of components had fallen to the lowest level in the year. 70% of the new installed capacity in the first half of the year were distributed power stations with relatively low price sensitivity, and centralized power stations with high price sensitivity had been suppressed. In the face of the continuous rise in supply chain prices, the Ministry of industry and information technology has led relevant departments to coordinate this issue, which is currently in progress.
