Munich, Germany - May 7, 2025 - LONGi Solar is proud to announce that its Hi-MO X10 back contact module is among the winners of the annual Smarter E AWARD 2025 in the Photovoltaics category. The award was presented last night in Munich, on the eve of The smarter E Europe exhibition, ahead of Intersolar 2025.
The Hi-MO X10 was recognized for its contribution to advancing module technology through the integration of LONGi’s proprietary second-generation Hybrid Passivated Back Contact (HPBC 2.0) technology that is based on the highly efficient LONGi TaiRay wafer. The jury further praised the zero-busbar (0BB) structure and the module’s Bipolar Hybrid Passivation Technology which brings significant improvements in efficiency, mechanical characteristics and reliability. The module’s shading optimizer technology furthermore reduces the loss of power output by 70% and decreases localized temperatures by up to 28% reducing the risk of hotspots and system fires, according to the jury’s summary. All in all, the Hi-MO X10 would set new standards for performance and reliability.
First launched in November 2024, the Hi-MO X10 has already been widely adopted in European markets. The module represents LONGi's strategic focus on R&D driven back contact innovation to meet performance, aesthetics and application requirements in a changing energy landscape.
The Hi-MO X10 is part of LONGi’s new EcoLife Series – a premium residential brand to be launched on May 7th at Intersolar
The Hi-MO X10 delivers a maximum power output of up to 670W for commercial and industrial (C&I) applications, and 500W in its 54-cell format for residential use. With a module efficiency of 24.8% and a cell efficiency of 26.6%, it outperforms conventional TOPCon modules by as much as 30W. The integration of zero busbar (0BB) technology enhances light absorption, improving performance in diffuse light—an advantage in markets with frequent overcast conditions. Designed for long-term reliability, the Hi-MO X10 features just 1% degradation in the first year and a 0.35% annual linear degradation rate. Its improved power temperature coefficient of -0.26%/°C ensures dependable output in both hot and moderate climates.
The Hi-MO X10 54-cell module is part of LONGi’s new premium end-consumer brand, the “EcoLife Series”, designed to make advanced solar technology more accessible for homeowners. Combining high performance, safety, and refined aesthetics, it offers long-term reliability and strong investment value. With EcoLife, LONGi addresses the practical needs of residential users by delivering trusted technology, streamlined service, and solutions tailored for modern living.
LONGi will showcase the Hi-MO X10 at Intersolar Europe 2025, opening today, May 7, and will officially unveil its latest high-efficiency back contact innovation at 11:00 AM at booth A2.170. External visitors are welcome to participate.
