655W Hi-MO 9 HPBC 66 Cell Double Glass Silver Frame MC4-EVO2

The LONGi Hi-MO 9 LR8-66HYD-655M is a 655W premium bifacial solar panel using N-type TOPCon and hybrid passivated back-contact (HPBC) cell technology. The panel delivers 24.2% module efficiency with 132 half-cut monocrystalline cells arranged in a 6×22 configuration. The 2382×1134mm panel weighs 33.5kg and combines dual-glass construction with 2.0mm coated tempered front glass and 2.0mm semi-tempered rear glass in a silver anodised aluminium frame. The 75% bifaciality factor allows the rear surface to generate significant additional energy from reflected light, making the panel ideal for ground-mounted installations or roofs with high reflection coefficients. Under standard test conditions, the module produces an open-circuit voltage of 49.82V and short-circuit current of 16.62A. Maximum system voltage rating is 1500V DC and operating range spans -40 to +85°C. Power loss is limited to 1% in year one, declining to 0.35% annually thereafter. An IP68 junction box with three bypass diodes provides electrical safety. The panel includes a 12-year warranty on materials and workmanship plus a 30-year linear power output warranty.
