Gokin Solar Launches BC Modules for Australia
Gokin Solar's back-contact solar module series is set to reach Australian rooftops from early 2027.
Updated on Nov. 3, 2026 in Energy
Gokin Solar unveiled its BC GK-3-54HGF back-contact solar module series for Australian rooftops on 3 November 2026. The company also signed agreements with OSW, GBP and Peak Energy.
Why it matters
The modules are positioned as an output upgrade for Australian rooftop installations, with Gokin claiming 6-10% more output than TOPCon products for the same installed area. The claim is company-reported and has not been independently verified in the extraction.
The BC GK-3-54HGF series is rated 495 W to 510 W with efficiencies up to 25%, and Gokin claims a 6-10% output advantage over TOPCon products. These are manufacturer-reported figures, and independent verification is not yet available.
The players
Gokin Solar
Gokin Solar is a Chinese solar manufacturer that controls its own wafers and sources cells from partners including Aiko.
The details
The modules use 108 N-type back-contact half-cells sourced from partner Aiko, and carry Clean Energy Council certification. The panel measures 1,800 mm by 1,134 mm by 30 mm, weighs 21.4 kg, and is rated for a 1,500 V maximum system voltage.
Timeline
3 November 2026: Gokin unveiled the BC module series and signed partner agreements.
Early 2027: The BC GK-3-54HGF modules are expected to become available in Australia.
Big Picture
Gokin positions its back-contact platform against TOPCon, the dominant rooftop module technology it claims to outperform by 6-10% for the same installed area. The claim is company-reported and the extraction does not include independent comparison data.
Rooftop installers and homeowners evaluating panels may see the BC series as an option once it becomes available in early 2027. The modules carry a 25-year product warranty and a 30-year linear performance guarantee.
The takeaway
For buyers planning rooftop systems, the 25-year product warranty and 30-year linear performance guarantee are the concrete terms to compare against other modules. The 6-10% output claim should be checked against independent test data before relying on it.
What happens next
The BC GK-3-54HGF modules are expected to become available in Australia from early 2027.
