AIKO was founded in 2009, is headquartered in China, and is publicly listed on the Shenzhen Stock Exchange (SZSE). It achieved BloombergNEF Tier 1 bankable status in Q3 2024 and has claimed production of over 130 GW of solar cells through 2024, with an additional 11 GW of ABC-dedicated module capacity being expanded. Gokin Solar is a newer entrant, founded in 2019 and based in Zhuhai, China. It is privately held, having raised roughly $746 million in funding, and reached a milestone of 3 million BC modules shipped as of early 2026 - but it does not yet appear on the BloombergNEF Tier 1 list. For any project requiring non-recourse finance from commercial banks, AIKO's Tier 1 status gives it a decisive institutional advantage. On paper, the two lineups are remarkably close in raw performance, which makes the non-technical differences matter more. AIKO's 144-panel portfolio averages 581 Wp and 23.65% efficiency, with a peak of 805 Wp and 25.2% - figures that reflect its leading ABC (All Back Contact) cells and place it squarely in the premium residential and utility segment. About 24.3% of its panels are bifacial, making roughly one-in-four modules suitable for ground-mount installations where rear-side gain is valuable. Its average temperature coefficient of -0.27%/°C is competitive. Gokin's 44-panel portfolio averages 517 Wp and 23.58% efficiency, peaking at 780 Wp and 24.5%, with Back Contact cells making up an even larger share of the range at 79.6%. Only 11.4% of Gokin's panels are bifacial, which narrows its utility-scale appeal. Gokin holds a slight edge on temperature coefficient (-0.26%/°C) and warranty length (30 years average versus AIKO's 29.5 years), small but real differences for long-horizon asset owners. For a typical buyer in 2025-2026, AIKO is the safer default. Its Tier 1 bankability removes a key barrier for project-financed or commercial-scale installations, its product catalog is broader, and its peak efficiency and power figures are the highest in this comparison. Gokin is a credible option for buyers who can accept a non-Tier-1 supplier - its BC technology is independently certified, its warranty stance is slightly stronger, and its lower temperature coefficient is a real benefit in hot climates - but it is still building the track record that lenders require. \---LINKS--- \- https://www.pv-magazine.com/2025/12/15/gokin-solar-launches-new-back-contact-solar-module-series/ \| Gokin Solar launches new back-contact solar module series \| article \- https://www.pv-tech.org/aiko-capacity-upgrades-abc-cell-technology/ \| Aiko steps up ABC transition with 11 GW capacity upgrade \| article \- https://www.pv-magazine.com/2025/03/12/aiko-launches-500-w-ci-back-contact-solar-module-with-25-efficiency/ \| Aiko launches 500 W C&I back-contact module with 25% efficiency \| article \- https://taiyangnews.info/technology/aiko-solar-abc-module-power-efficiency \| AIKO's ABC Module - Making The Most Of Each Electron \| article \- https://solarquarter.com/2026/05/11/gokin-solar-hits-3-million-bc-module-milestone-reinforcing-global-pv-supply-capacity/ \| Gokin Solar hits 3 million BC module milestone \| article Sources: \- \[Gokin Solar launches new back-contact solar module series\](https://www.pv-magazine.com/2025/12/15/gokin-solar-launches-new-back-contact-solar-module-series/) \- \[Aiko steps up ABC transition with 11 GW capacity upgrade\](https://www.pv-tech.org/aiko-capacity-upgrades-abc-cell-technology/) \- \[Aiko launches 500 W C&I back-contact module with 25% efficiency\](https://www.pv-magazine.com/2025/03/12/aiko-launches-500-w-ci-back-contact-solar-module-with-25-efficiency/) \- \[AIKO's ABC Module - Making The Most Of Each Electron\](https://taiyangnews.info/technology/aiko-solar-abc-module-power-efficiency) \- \[Gokin Solar hits 3 million BC module milestone\](https://solarquarter.com/2026/05/11/gokin-solar-hits-3-million-bc-module-milestone-reinforcing-global-pv-supply-capacity/) Written by claude-sonnet from the figures above. ## Other comparisons - [Gokin vs A.B.
