From February 19 to 21, the prestigious World Smart Energy Week took center stage at Tokyo Big Sight Exhibition Center. As a premier event in Asia’s renewable energy sector, the exhibition spotlighted the latest advancements in photovoltaics, energy storage, smart grids, and other cutting-edge technologies—offering invaluable insights and collaboration opportunities for the global energy transition. A frontrunner in heterojunction (HJT) solar technology, Huasun Energy made a powerful impression, unveiling its latest innovations and capturing widespread attention.
Japan, a global leader in technological innovation and often referred to as the “birthplace of heterojunction technology,” is accelerating its energy transition. The government has set ambitious targets to raise renewable energy’s share to 36%-38% by 2030 and achieve carbon neutrality by 2050. This commitment creates a vast market for high-efficiency, reliable photovoltaic solutions.
Huasun’s full lineup of HJT modules, engineered with ultra-high efficiency half-cell technology, delivers superior power output, high bifaciality, minimal degradation, exceptional low-light performance, and outstanding reliability—perfectly aligning with Japan’s exacting quality and performance standards.
Given Japan’s high urban density and scarce land resources, rooftop solar has emerged as a key driver of energy generation. At this year’s exhibition, Huasun showcased its Everest Series G12R-96 Color and G12R-132 Transparent Black rectangular HJT modules, tailor-made for residential and commercial distributed solar applications. Featuring cutting-edge zero-busbar (0BB) technology, these modules offer exceptional performance and durability. Their sleek aesthetic—available in color and transparent black—seamlessly integrates with architectural designs. The colored glass boasts superior UV resistance over conventional transparent glass, achieving up to 80% light transmittance, while the composite frame significantly reduces carbon emissions compared to traditional aluminum frames, combining sustainability with design excellence for the Japanese market.
As Japan’s mature solar sector explores new growth frontiers, agrivoltaics is emerging as a promising opportunity. In a market-first debut, Huasun introduced its Kunlun Series G12-132 Vertical HJT module, captivating attendees with its breakthrough performance. With a mass production power output of up to 720 W and an efficiency of 23.2%, along with outstanding bifacial generation and low-light response, this module excels in vertical installations. Its versatility makes it an ideal solution for agriculture, transportation, and fencing applications, pushing the boundaries of solar deployment in Japan and beyond.
Huasun’s return to World Smart Energy Week underscored the surging demand for HJT technology, drawing strong interest from Japan’s top companies. Moving forward, Huasun remains committed to pioneering innovation, delivering high-performance solar solutions, and collaborating with industry partners to drive the evolution of the solar sector—powering a sustainable future in Japan and across the globe.
