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.
