Authorised Gokin Solar Distributor in New Zealand 15-Year Product Warranty 30-Year Linear Power Warranty Exceptional Module Efficiency – 23.5% Gokin Solar GBC All Black Series – 480W Bifacial Dual-Glass Solar Panel The GK-3-54HGDb-480M combines advanced GBC back-contact cell technology with a premium all-black design. Delivering 480W output and 23.5% efficiency, it generates more power from limited roof space while providing a clean appearance without visible front busbars. Its bifacial dual-glass construction can utilise reflected light from the rear for additional energy generation. Partial-shading optimisation, strong low-light performance and a low power temperature coefficient help maintain reliable output under changing conditions. The durable 2.0mm + 2.0mm dual-glass structure offers excellent resistance to micro-cracks, high temperatures and severe weather. Highlights: 480W output | 23.5% efficiency GBC back-contact cell technology Bifacial, all-black dual-glass design Partial-shading optimisation Power temperature coefficient: -0.26%/°C Front/rear static load: 5400Pa / 2400Pa 15-year product warranty | 30-year linear power warranty Model: GK-3-54HGDb-480M Testing Condition: STC Maximum Power (Pmax/W): 480 Open Circuit Voltage (Voc/V): 40.76 Short Circuit Current (Isc/A): 14.96 Voltage at Maximum Power (Vmp/V): 33.84 Current at Maximum Power (Imp/A): 14.19 Module Efficiency: 23.5% Mechanical Parameters Cell Type: GBC Cell Orientation: 108 cells (6 × 18) Junction Box: IP68 Output Cable: TÜV 1 × 4mm², (+)300mm and (-)200mm Glass: Dual glass, 2.0mm + 2.0mm coated semi-tempered glass Frame: Black anodised aluminium Connector: MC4 compatible / MC4-Evo2 Weight: 24.8kg Dimensions: 1800 × 1134 × 30mm Maximum System Voltage: 1500V DC Maximum Series Fuse Rating: 25A Fire Rating: IEC Class C Ideal for premium residential rooftops and space-limited installations requiring high energy yield and refined aesthetics.
