First Solar vs AIKO - solar panel manufacturer comparison

First Solar is an American manufacturer headquartered in Tempe, Arizona, founded in 1999 and traded on the NASDAQ. It is the only large-scale module producer based in the Western hemisphere and has consistently held a strong bankability position with institutional financiers. The company operates factories across the United States, India, Malaysia, and Vietnam, and by 2025 its combined nameplate capacity had grown well beyond 14 GW annually, with further expansion underway toward a stated target approaching 20 GW. AIKO is a Chinese manufacturer founded in 2009 and headquartered in Guangzhou, China. It holds Bloomberg NEF Tier 1 bankability status and has reported annual production capacity exceeding 5 GW, a figure that has grown rapidly alongside its technology push. Between the two, First Solar carries the stronger institutional footprint in Western markets, particularly in the United States where domestic manufacturing grants it significant advantages under the Inflation Reduction Act.

The two companies serve almost entirely different market segments, which makes a head-to-head comparison somewhat unusual. First Solar produces its Series 6 and Series 7 modules, both built on its proprietary cadmium telluride (CdTe) thin-film technology. These large-format modules are engineered almost exclusively for utility-scale ground-mount projects, and the company does not meaningfully compete in the residential or small commercial rooftop segment. AIKO, by contrast, has staked its identity on N-type all back contact (ABC) cell technology, which eliminates front-side shading losses by moving all electrical contacts to the rear of the cell. Its Neostar series targets residential rooftops with compact high-efficiency panels, the Comet series serves commercial and industrial rooftops at higher wattages, and the company has also introduced bifacial ABC modules aimed at utility applications.

For a residential or commercial rooftop buyer in 2025, First Solar is simply not a realistic option - its products and sales model are oriented toward large project developers. AIKO, with its ABC technology and strong installer reception, is a credible premium choice for those segments. For utility-scale developers, particularly in North America, First Solar's domestic supply chain, thin-film performance advantages in high-temperature environments, and deep project-finance track record make it the default institutional pick. The two brands are not interchangeable - the right choice depends almost entirely on project scale and geography.
