What makes heterojunction fit for utility scale solar projects?

Huasun Energy, in collaboration with pv magazine, recently delivered an insightful webinar titled "Heterojunction at the Pinnacle of its Power" to an eager audience of 500 industry experts on November 9, 2023.

Moderated by Emiliano Bellini, News Director at pv magazine, Huasun Energy discussed the remarkable efficiency increases and how the company is integrating the results in commercial production including analyzing in details of heterojunction (HJT) solar cell and module technologies. Christian Comes, Director of Business Development Europe and Anna Paskaleva, Sr. Sales Manager Europe elaborated on why HJT is perfectly fitting for utility scale photovoltaic project and demonstrated the practical use on world’s largest HJT plant in Bulgaria.

Moderated by Emiliano Bellini, the News Director at pv magazine, Huasun Energy unveiled impressive efficiency advancements and the seamless integration of these breakthroughs into their commercial production. The discussion delved into the intricacies of heterojunction (HJT) solar cell and module technologies, joined by Christian Comes, Director of Business Development Europe, and Anna Paskaleva, Senior Sales Manager Europe. They also offered a comprehensive explanation of why HJT technology is ideally suited for utility-scale photovoltaic projects, exemplifying its practical application at the world's largest HJT plant in Bulgaria.

Heterojunction modules stand out as the perfect solution for large-scale utility solar projects, owing to their exceptional advantages, including high efficiency, stellar performance, unrivaled reliability, and cost-effectiveness attributed to rapid industrialization.

Recent reports from Taiyangnews highlight a remarkable reduction in the factory CAPEX of heterojunction technology, dropping from RMB 1000M/GW in 2019 to RMB 300M/GW in 2023. HJT is now at the forefront of rapid technological innovation, with Huasun successfully integrating HJT 3.0 cell technology featuring a 120μm wafer, with future plans to further advance to a 90μm wafer. Upcoming advancements such as 0BB and copper plating will further reduce the use of silver, ultimately driving down the costs associated with heterojunction technology and making it the prevailing choice in the PV industry.

With 18 years of experience in the PV sector, Christian Comes expressed his optimism in welcoming more industry players to join the game, emphasizing the importance of collective efforts to propel the rapid development of HJT. That's why Huasun initiated and organized the HJT collaborative innovation platform in July this year, with more than 120 member companies spanning the entire value chain joining forces to expedite the industrialization of HJT technology.

Anna Paskaleva added, "We are delighted to witness a growing interest from the industry in HJT in recent years. Thanks to the joint efforts led by Huasun, we have successfully brought this exceptional technology to an industrial scale."

Huasun Energy boasts multiple manufacturing facilities in key industrial cities across China, with a capacity projected to surpass 20GW by the end of 2023. The company has set a series of TUV SUD-certified efficiency records for both HJT solar cells and modules. In Early November, Huasun achieved a remarkable 25.8% power average conversion efficiency in a solar cell mass production. Additionally, their Himalaya G12-132 heterojunction solar module achieved an impressive output of 750.544 W and a power conversion efficiency of 24.16%.

Earlier this year, Huasun signed a strategic agreement with Inercom, a renowned EPC company in Bulgaria, to supply 1.5GW of high-efficiency HJT modules for utility-scale solar projects by 2025. To date, 350MW of the Apriltsi Village solar project has been completed, the owner is reporting 32% higher energy yield than expected based on initial calculations. The project owners spoke highly of the performance of Huasun's high-efficiency HJT modules which delivered high energy yield. HJT has demonstrated to the world its positive impact on investors' balance sheets. "We believe that maybe in five years, heterojunction is going to be the majority of the production of solar panels in the world.”
