On February 17, 2025, the Huasun HJT Exclusive Gala took place in Tokyo, uniting nearly 100 key stakeholders from Japan’s solar energy industry. The event brought together prominent project developers, EPCs, solar distributors, investment firms, and industry media to discuss the latest advancements in heterojunction (HJT) solar technology and its applications.
Japan is a critical market for renewable energy, fueled by progressive policies and continuous technological innovation. As the birthplace of HJT technology, Japan has established a strong market for high-efficiency HJT solar solutions, which are widely used in both rooftop and utility-scale projects. The country aims to generate 36%–38% of its electricity from renewable sources by 2030, with solar power expected to contribute 14%–16%. This ambitious goal opens up significant opportunities for advanced photovoltaic (PV) technologies like HJT.
Criss Jin, General Manager of Huasun’s Overseas Sales & Marketing Center, welcomed attendees, emphasizing Japan’s vital role in the development of HJT solar technology and its close ties to Huasun. “Japan is particularly significant for Huasun as the origin of HJT. In 2021, we delivered our first batch of HJT modules to a 6 MW ground-mounted solar project in Hamamatsu, Shizuoka. Today, we have surpassed 10 GW in global shipments, a milestone achieved through the trust and support of our partners. With our latest technological breakthroughs and extensive commercial experience, we are eager to introduce new HJT products and system solutions to the Japanese market.”
The event featured a keynote address by Mr. Ryu Junsei, CEO of WWB Corporation, a leading Japanese renewable energy company. As a respected figure in the green energy sector, Mr. Ryu highlighted HJT technology’s advantages: “HJT is widely recognized as one of the most competitive solar technologies available today. Witnessing Huasun’s rapid industrialization of this technology and its tangible benefits for PV projects is genuinely inspiring. I urge 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 detailed overview of the company’s HJT technology, product advantages, and market applications. Earlier this year, Huasun successfully began mass production of 730 W high-power modules. With a strong track record of commercial success, leading power output, and efficiency, the company is committed to ongoing research and development, aiming to push cell efficiency beyond 27% by 2025.
HJT is not only one of the most advanced PV technologies today but is also an ideal platform for developing perovskite tandem cells, which have the potential 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. In the near future, the integration of these technologies could enable solar modules to exceed 800 W in power output and achieve 28% efficiency,” noted Ms. Kosugi.
During the final session, Mr. Makoto Tsuchida, President of Ecostu Corporation, shared insights from a project development perspective. “Through extensive research and real-world performance data from Huasun, we have confirmed that HJT technology, with its high bifaciality, superior low-light performance, and excellent temperature coefficient, delivers higher energy yields compared to TOPCon or BC products. This translates into stronger investment returns, making Huasun’s HJT modules an outstanding choice for our projects.”
Huasun’s HJT product portfolio spans utility-scale, commercial and industrial, residential, and agrivoltaic applications. The company will showcase its full range of solutions at the upcoming World Smart Energy Week, taking place from February 19-21 at Tokyo Big Sight. Industry professionals will have the opportunity to explore Huasun’s latest innovations in HJT technology and engage in discussions about the future of solar energy.
