LONGi has announced that a PV power plant at a factory owned by Longfei Wood Products in China’s Heilongjiang province has been connected to the grid, making it the first HPBC 2.0 distributed power plant to be officially put into commercial operation.
■ Longfei Wood Products Factory PV Power Plant
The plant has an installed capacity of 2.2 MW and deploys LONGi’s industry-leading HPBC 2.0 dual-glass PV modules with a power output of 630W. The plant generates an annual output of 3.2 million kWh, providing electricity for the factory while also yielding annual electricity sales revenue of 1.2 million RMB.
The HPBC 2.0 modules deliver superior power generation performance, supplying an additional annual 110,000 kWh when compared to a TOPCon based plant of the same capacity, representing a 3.56% power gain.
Based on the same surface area, the LONGi modules increase installed capacity by 5% compared to TOPCon equivalents, translating into an 8.56% power generation gain.
To maximize installed capacity and power generation, the project adopted ground-mounted installation at an optimal tilt angle. This method ensures maximum absorption of solar radiation, significantly improving efficiency. Compared to a flat rooftop installation, the ground-mounted approach delivers 25% more power generation while offering easier maintenance and lower operational costs.
HPBC 2.0 builds on the strong foundation of its first generation, overcoming critical technical challenges in cell substrates, passivation technology and manufacturing process technology. Its cell efficiency exceeds 26.6%, making it the world’s most efficient cell technology in mass production. The technology incorporates LONGi’s proprietary high-quality TaiRay silicon wafers, significantly reducing PV cell degradation, with the company’s self-developed bipolar composite passivation technology achieving an open circuit voltage exceeding 745 mV, reducing current loss and further improving conversion efficiency.
Compared to TOPCon modules, HPBC 2.0 products exhibit superior resistance to UV, damp heat and thermal cycling, also featuring a temperature coefficient of -0.26%/°C, an improvement of 0.03%/°C over TOPCon. In Heilongjiang, China’s northernmost province, where winter temperatures can drop as low as -30°C, the modules demonstrate outstanding durability and reliable performance under extreme conditions.
The establishment of the first HPBC 2.0 power plant not only supports the area’s transition from a timber-based to an ecological economy, but also illustrates the nationwide potential for HPBC 2.0 distributed power plants to take root and flourish.
As the BC technology ecosystem continues to expand, LONGi remains committed to working alongside its partners to deliver premium PV power plants for commercial and industrial customers.
