Solar module producer Longi announced May 26 that the prices of all its wafer products will be raised in June.
The G1 products with the size of 158.75mm were priced at RMB4.79 per piece, with an increase of RMB0.40, 9.1%, compared to the previous value.
The new price for M6 wafers with the size of 166mm increased by RMB0.40 to RMB4.89 per piece.
The 182mm M10 wafers were priced at RMB5.87 per piece, up RMB0.48.
It is the second time that Longi has raised its prices in May, after doing so on May 14.
The silicon branch of the China Nonferrous Metals Association reported that polysilicon reached a price of RMB200-210 per kg, and that the highest price exceeded RMB230 per kg. Major downstream buyers and upstream suppliers are in price negotiations for long-term supply orders for next month.
According to industry sources, many prices for long-term orders have risen to around RMB200 per kilo and even higher. Some buyers have started trying to settle price for July.
Since average supply prices rise sharply, industry observers say wafer prices are estimated to continue growing in June.
