It has been recently reported that the Apriltsi solar power project located in Bulgaria, has completed the installation of over 824,000 photovoltaic modules, totaling a capacity of 400 MW. Of particular note, the Apriltsi project represents the world’s largest single-site heterojunction (HJT) solar project. Huasun Energy, a leading global player in HJT technology, has been exclusively supplying HJT PV modules to the project since 2021, chosen for their exceptional performance, swift delivery, and professional service.
The Apriltsi project distinguishes itself with advanced heterojunction (HJT) photovoltaic panels renowned for superior efficiency and output compared to traditional crystalline silicon cells, along with enhanced durability and lower degradation. Furthermore, the superior temperature coefficient of HJT modules ensures stable output even at high ambient temperatures during the summer season.
As a prominent representative of n-type high-efficiency photovoltaic technology products, HJT modules are widely acclaimed in the European market for their high conversion efficiency, high power output, high bifaciality, high reliability, and low carbon emissions.

Looking at Huasunโs participation in large-scale photovoltaic projects close to home, in mid-2023, Huasun signed an agreement with PowerChina Huadong Engineering Corporation to supply a total of 2.02 GW of its G12-132 HJT modules to its large-scale solar power plants located in Dali, Yunnan province. The PV plants, constructed on mountains, will aid the prefecture in achieving its clean energy targets. To date, 300 MW of these projects have been built up.
As of 2024, Huasun has supplied more than 5GW of high-efficiency HJT products to more than 40 countries and regions worldwide, including China, Bulgaria, Germany, Switzerland, India, Pakistan, Japan, Thailand, Tunisia etc. Ensuring sustained customer satisfaction, Huasun consistently delivers superior quality and service.

As a frontrunner in the industrialization of HJT technology, Huasun has successfully established four production bases in Xuancheng and Hefei, located in Chinaโs Anhui Province, as well as in Wuxi, Jiangsu Province, and Dali, Yunnan Province. This forms a vertically integrated industrial chain encompassing silicon wafers, cells, and modules, with an annual capacity of 20GW, firmly establishing itself as a leader in HJT production capabilities.
Continuing to delve into the potentials of n-type HJT technology, Huasun has solidified its Bloomberg NEF (BNEF) Tier 1 position. Moving forward, Huasun pledges to maintain vigilance over market trends, serving the global clients with cutting-edge products and top-tier services. In doing so, it aims to propel the photovoltaic sector to the forefront of global energy provision, thereby fostering the transition towards a greener, zero-carbon future.
