Recently, Stage 1 of LONGi Green Energy's Phase I 12.5GW High-Efficiency BC (Back Contact) Cell Project in Xixian New Area successfully completed its environmental protection acceptance inspection upon completion and initiated the public notification phase.
It is reported that the planned total investment for the project is 3.206 billion yuan, while the Stage 1 engineering that passed the acceptance inspection this time involves an investment of 1.248 billion yuan. Phase I of the project aims for an annual production capacity of 12.5GW of high-efficiency BC cells. By leasing customized factory buildings and ancillary structures, the company has deployed cell production lines and auxiliary equipment in Workshop 1. At present, 6.25GW of high-efficiency BC cell production capacity has been constructed. This recent inspection specifically targets the environmental protection compliance of this completed portion, which constitutes Stage 1 of the Phase I project.
Previously, in July 2025, the project had already achieved the commissioning of its first production line. This project is a crucial component of LONGi's capacity layout for high-efficiency BC cells. Once fully constructed, it will further enhance LONGi's production scale and manufacturing capabilities in the high-efficiency BC cell sector.
Currently, the average mass production efficiency of LONGi's BC cells has reached 27%, as verified by authoritative international third-party certifications. The mass production power for its mainstream module formats ranges from 650W to 670W, with a peak power of 680W and a mass production conversion efficiency of 24.8%. According to the company's plan, by the fourth quarter of 2026, 50% of LONGi's BC modules will feature a power output concentrated within the 670W to 680W range.
In terms of shipment volume, LONGi's BC module shipments reached 8.34GW in the first quarter of 2026, primarily consisting of HPBC 2.0 products. The company's overall module shipment target for 2026 is approximately 80GW. Among this, BC modules are expected to account for over 65%, equating to more than 52GW, which will further consolidate the core dominant position of BC products in the future.
