On February 17, 2025, the Huasun HJT Exclusive Gala Japan took place in Tokyo, attracting nearly 100 key figures from Japan’s solar energy sector. The event brought together prominent project developers, EPCs, solar distributors, investment firms, and industry media, all focused on discussing the latest advancements in heterojunction (HJT) solar technology and its applications.
Japan remains a crucial market for renewable energy, driven by progressive policies and continuous technological innovation. As the birthplace of HJT technology, Japan has developed a robust market for high-efficiency HJT solar solutions, which are widely utilized in both rooftop installations and utility-scale projects. The nation aims to source 36% to 38% of its electricity from renewable sources by 2030, with solar power projected to contribute 14% to 16%. This ambitious goal creates significant opportunities for advanced PV technologies like HJT.
Criss Jin, General Manager of Huasun’s Overseas Sales & Marketing Center, welcomed the attendees and underscored Japan’s vital role in the development of HJT solar technology, as well as its strong connection with Huasun. “Japan is of special significance to Huasun as the origin of HJT. In 2021, we delivered our first batch of HJT modules for a 6 MW ground-mounted solar project in Hamamatsu, Shizuoka. Today, we have exceeded 10 GW in global shipments, a milestone made possible through the trust and support of our partners. With our latest technological advancements and extensive commercial experience, we are eager to introduce new HJT products and system solutions to the Japanese market,” he stated.
The event featured a keynote address from Mr. Ryu Junsei, CEO of WWB Corporation, a leading Japanese renewable energy company. Renowned in the green energy sector, Mr. Ryu emphasized the advantages of HJT technology: “HJT is widely recognized as one of the most competitive solar technologies available today. Huasun’s rapid industrialization of this technology and its tangible benefits for PV projects are truly inspiring. I encourage the industry to collaborate in accelerating the adoption of cutting-edge technologies, making solar energy more efficient and cost-effective for businesses and households worldwide.”
Ms. Kosugi Tobai, Huasun’s Business Head for Japan, provided a comprehensive overview of the company’s HJT technology, its product advantages, and market applications. Earlier this year, Huasun commenced mass production of 730 W high-power modules. With a proven track record of commercial success, industry-leading power output, and efficiency, the company is committed to ongoing R&D, aiming to push cell efficiency beyond 27% by 2025.
HJT technology is not only among the most advanced PV technologies available today but also serves as an ideal platform for developing perovskite tandem cells, potentially allowing for significant efficiency improvements. “Huasun currently operates with 20 GW of HJT production capacity and is actively developing a 100 MW pilot line for HJT-perovskite tandem cells. Soon, we could see solar modules exceeding 800 W in power output and achieving 28% efficiency,” Ms. Kosugi noted.
In the concluding session, Mr. Makoto Tsuchida, President of Ecostu Corporation, shared insights from a project development perspective. “Based on extensive research and real-world performance data from Huasun, we have confirmed that HJT technology, with its high bifaciality, excellent low-light performance, and superior temperature coefficient, yields higher energy outputs compared to TOPCon or BC products. This translates into better investment returns, making Huasun’s HJT modules an outstanding choice for our projects.”
Huasun’s HJT product portfolio caters to various applications, including utility-scale, commercial and industrial, residential, and agrivoltaic uses. The company’s complete range of solutions will be showcased at the upcoming World Smart Energy Week, scheduled for February 19-21 at Tokyo Big Sight. This event will provide industry professionals with the opportunity to explore Huasun’s latest innovations in HJT technology and engage in discussions regarding the future of solar energy.
