Delivered 13 GW Of HJT Products In 80 Countries: Huasun Energy

Huasun Energy is marking its fifth anniversary with a milestone achievement: a rapid rise from a startup to the world’s leading manufacturer of ultra-high-efficiency heterojunction (HJT) solar products.

Founded in 2020, the China-based firm has expanded its footprint to five major manufacturing hubs across Xuancheng, Hefei, Wuxi, Dali, and Yinchuan, reaching a production capacity of 20 GW. Its fully integrated supply chain spans from ingots to finished solar modules. Huasun said it has delivered more than 13 GW of HJT products to over 80 countries and regions worldwide.

An Untapped Potential 

Chairman Jimmy Xu, reflecting on the company’s journey, said the firm was launched with a strong belief in the untapped potential of HJT technology. “I believed from the start that HJT would lead the next era of solar,” Xu said. “It offers the high efficiency, low degradation, and application flexibility that the world needs for sustainable energy.”

Huasun entered the market during the peak of PERC technology’s dominance but opted for HJT citing its superior long-term potential. Since then, the company has rolled out several product lines, including the Himalaya, Everest, and Kunlun series.

Himalaya G12-132 module

Among them, the Himalaya G12-132 module has drawn global attention for reaching a record-breaking 768.9 W in champion power and up to 730 W in deliverable output with 23.5% module efficiency. These modules have been deployed in extreme conditions—such as marine and desert environments—and feature advanced encapsulation technology, including EVA, light conversion film, butyl adhesive, and glass-glass architecture for enhanced durability.

The newly launched Kunlun series targets vertical PV applications such as agriculture, transport corridors, and architectural facades. The modules, boasting nearly 100% bifaciality, are being used in Europe through a partnership with Next2Sun AG, powering nearly 100 MW of vertical installations across sectors like Agri-PV and solar fencing.

These vertical systems offer advantages such as reduced snow and dust buildup, better light capture, and lower land-use impact—key for adoption in land-constrained regions.

HJT-perovskite tandem cells

Looking ahead, Huasun has already commissioned a 100 MW pilot line for HJT-perovskite tandem cells. The company aims to launch a next-generation module with over 800 W output and 25.75% efficiency by late 2026.

As it enters its sixth year, Huasun said it remains focused on "science, speed, and sustainability" as guiding principles. “We’re committed to delivering accessible, high-performance solar solutions to power a cleaner world,” the company said in a statement.
