LONGi Solar Panel — Hi-MO X Series with HPBC Technology for Ultimate Efficiency & Reliability
LONGi Green Energy is the world's largest solar technology company and the global leader in monocrystalline silicon innovation, with over 100 GW of cumulative wafer and module shipments. The Hi-MO X series features proprietary HPBC (Hybrid Passivated Back Contact) cell technology, delivering record-breaking module efficiency, exceptional aesthetics with all-black design, and outstanding reliability for residential, commercial, and utility-scale installations across Europe, Middle East, Northern Africa and worldwide.
- HPBC Proprietary Cell Technology — LONGi's patented HPBC (Hybrid Passivated Back Contact) technology places all electrical contacts on the rear side, eliminating front busbar shading. This breakthrough design achieves module efficiency exceeding 23.0% — among the highest in mass production — with a pure black, visually stunning appearance.
- World-Leading Monocrystalline Quality — As the pioneer and global leader of monocrystalline silicon technology, LONGi controls the entire value chain from ingot pulling and wafer slicing to cell manufacturing and module assembly. Each module benefits from LONGi's industry-defining wafer quality and precision manufacturing.
- Ultra-Low Degradation & 25-Year Warranty — LONGi modules feature best-in-class degradation rates — less than 1% in the first year and less than 0.4% annually thereafter. The 25-year linear power warranty guarantees at least 84.8% output at year 25, backed by LONGi's AAA bankability rating and financial strength.
- Premium All-Black Aesthetic Design — The Hi-MO X series showcases a sleek, all-black appearance with no visible busbars on the front face — ideal for residential and commercial installations where aesthetics matter. Premium looks combined with premium performance make LONGi the preferred choice for design-conscious projects.
