Gokin vs AIKO - solar panel manufacturer comparison

Gokin Solar and AIKO Solar are both Chinese manufacturers staking their reputations on Back Contact (BC) cell technology, but they occupy meaningfully different positions in the industry. 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.
