650W Hi-MO 9 HPBC 66 Cell Double Glass Silver Frame MC4-EVO2

The LONGi Hi-MO 9 LR8-66HYD-650M is a 650W high-efficiency bifacial solar panel based on N-type TOPCon and hybrid passivated back-contact (HPBC) cell technology. The panel achieves 24.1% module efficiency with 132 half-cut monocrystalline cells in a 6×22 configuration. The 2382×1134mm panel weighs 33.5kg and features dual-glass construction with 2.0mm coated tempered front glass and 2.0mm semi-tempered rear glass in a silver anodised aluminium frame. The bifaciality factor of 75% enables substantial energy generation from the rear surface when installed on reflective surfaces, ideal for ground-mounted arrays or roofs with high ground reflection. Standard test conditions produce open-circuit voltage of 49.72V and short-circuit current of 16.54A. Maximum system voltage is 1500V DC with operating range from -40 to +85°C. First-year degradation remains below 1% with 0.35% annual losses thereafter. An IP68 junction box with three bypass diodes ensures electrical protection. The panel carries a 12-year warranty on materials and workmanship plus a 30-year linear power output warranty.
