LONGi Solar Hi-MO S10 with HJT back contact technology: Maximum performance – impressive appearance – optimized shading performance

Our module partner LONGi Solar is launching three additional high-performance modules on the European market, which are expected to be among the future focus products. From the previously presented Hi-MO X10 series, we expect to receive the LR7-54HVBB, full-black modules with 475 Wp, in October 2025. The Hi-MO S10 series is brand new and is available as a Full Black version (LR7-54HJBB) and a transparent version (LR7-54HJD).

LONGi Solar wins German Excellence Award 2026 for its EcoLife solar module

LONGi Solar has been awarded the German Excellence Award 2026 for its 500 W EcoLife residential solar module in the category “Energy and Environment.” Under the title “LONGi EcoLife: More power, more security – the panel for an uncertain climate future,” the jury recognized the world’s first commercially available HIBC (Hybrid Interdigitated Back-Contact) solar module for combining very high efficiency with verified climate resilience, long-term safety, and a design approach tailored to modern residential architecture.
