## Summary

AIKO is a Chinese manufacturer founded in 2009 and headquartered in Guangzhou, Guangdong province. The company achieved BloombergNEF Tier 1 status in Q3 2024 and has scaled rapidly, with reported production capacity of roughly 20 GW per year in early 2025 and continuing upward momentum that placed it among the top ten Tier 1 manufacturers by volume in 2026. Silfab Solar is a North American manufacturer with roots in Italy and Canada, currently operating module plants in Ontario, Washington state, and South Carolina, with a combined North American module capacity approaching approximately 3.4 GW. Silfab holds Tier 1 bankability recognition from third-party testing laboratories RETC and Kiwa-PVEL, and has received RETC's "High Achievement in Performance" designation for four consecutive years through 2025. On raw institutional footprint and global production scale, AIKO holds the larger position by a wide margin.

AIKO's defining technology is its proprietary ABC (All Back Contact) n-type cell architecture, which moves all electrical contacts to the rear of the cell and has pushed some modules into the 23-25 percent efficiency range for residential rooftop applications. The ABC platform is marketed for premium residential installs, commercial and industrial rooftops, and increasingly utility-scale projects. Silfab centers its residential and light-commercial lineup around n-type TOPCon cells, with module efficiencies in the 20-22 percent range. Its Elite and Prime series are specifically aimed at the North American residential market and carry a 25-year product warranty and a 30-year performance warranty - among the longer coverage terms available in the industry. Silfab's domestic manufacturing also makes its modules eligible for U.S. Inflation Reduction Act domestic content bonuses, a meaningful financial advantage for American buyers.

For a buyer who prioritizes peak efficiency and is comfortable with a Chinese-manufactured product, AIKO offers a compelling technical edge. For a buyer in the United States who values North American manufacturing, domestic content incentives, and a long established track record with U.S. installers, Silfab is the more pragmatic default. The two brands occupy genuinely different niches and are not interchangeable choices.
