475W Hi-MO X10 Artist HPBC 54 Cell All Black MC4-EVO2

The LONGi Hi-MO X10 Artist LR7-54HVB-475M is a 475W residential solar panel with single-glass construction and an all-black appearance. Built on N-type hybrid passivated back-contact (HPBC2.0) cell technology, the panel achieves 23.3% module efficiency with 108 half-cut monocrystalline cells arranged 6×18. The 1800×1134mm panel weighs 21.6kg and combines 3.2mm coated tempered glass with a black anodised aluminium frame. Under standard test conditions, the module produces an open-circuit voltage of 40.18V and short-circuit current of 15.03A. Maximum system voltage is 1500V DC and the panel operates across -40 to +85°C. Initial power loss is limited to under 1% in year one, with 0.35% annual degradation thereafter. The panel is backed by a 25-year materials and workmanship warranty and a 30-year linear power output warranty.
