Huasun Energy is marking its fifth anniversary, celebrating the rise from ambitious startup to the world’s leading manufacturer of ultra-high-efficiency heterojunction (HJT) solar products. During the past five years, the company has established five manufacturing facilities across China, in Xuancheng, Hefei, Wuxi, Dali and Yinchuan, reaching 20 GW of production capacity with a fully integrated supply chain from ingots to modules. To date, the company has delivered over 13 GW of HJT products to more than 80 countries and regions worldwide.
Founded in 2020 amid a saturated PERC market, Huasun set its sights on HJT technology for its technical advantages and untapped potential. “I believed from the start that HJT would lead the next era of solar,” reflected Chairman Jimmy Xu. “It offers the high efficiency, low degradation and application flexibility that the world needs for sustainable energy.”
Among its several product lines, the Himalaya G12-132 module stands out with a record-breaking 768.9W in power output and up to 730W in deliverable output with a corresponding 23.5% module efficiency. The G12-132 modules have been deployed in utility-scale solar projects operating under extreme conditions, including marine and desert environments. With advanced encapsulation technology incorporating EVA, light conversion film, butyl adhesive and a glass-glass design, they offer exceptional performance, durability and long-term reliability..
The new Kunlun series, featuring near-100% bifaciality, is designed for vertical PV applications including farmland, transportation corridors and building facades. In Europe, Huasun has partnered with leading companies on nearly 100 MW of vertical PV projects across sectors including Agri-PV and solar fencing, the projects receiving praise for reducing snow and dust buildup, capturing reflected light and minimizing land disruption.
In its fifth year, the company has established a 100 MW pilot line for HJT-perovskite tandem cells, aiming to launch a next-generation module with power output of over 800 W and a 25.75% efficiency by late 2026. With a foundation built on science, speed and sustainability, Huasun remains at the forefront of solar innovation—delivering accessible, high-performance solutions to power a cleaner world.
