PVTIME – PV giant LONGi recently announced plans to invest 3.2 billion yuan (around US$440 million) in the construction of 12.5GW BC production lines in China’s Shaanxi province.
As its BC products reached mass production in the first half of 2024, LONGi plans to expand its production capacity to promote the industrialisation of BC modules. This 12.5GW capacity is the first phase of the project and will be completed by the end of 2024, with full operation in June 2025.
The core products of LONGi’s self-developed BC 2.0, which uses n-type TaiRay silicon wafers and advanced composite passivation technology, achieves a maximum conversion efficiency of 26.6% and a module power of 660W, much higher than that of the TOPCon products.
On 9 July 2024, LONGi claims to be focusing on the second generation of BC products with massive investment. According to its plan, the total production capacity of BC 1.0 and 2.0 will reach 70GW by the end of 2025, with 50GW of BC 2.0 and 20GW of BC 1.0. Most of its plants producing PERC will be rebuilt and reconfigured to produce BC 2.0 products. Then all of LONGi’s factories in China will be upgraded to produce BC products by the end of 2026, except for some of its overseas factories. In addition, LONGi has secured an order for 1GW of Hi-MO9 modules in less than 2 months since the launch of this BC product in early May 2024, and a further 5GW of the same modules is under negotiation, according to LONGi.
