AKCOME vs Sunplus - solar panel manufacturer comparison

AKCOME is a Chinese solar manufacturer founded in 2006 and headquartered in Jiangsu province. The company has built an annual module production capacity of roughly 3.8 GW alongside 5 GW of solar mounting structures, and it operates across more than 30 countries with a workforce of over 6,000. AKCOME held BloombergNEF Tier 1 status for several years, though it was removed from that list in 2024. Sunplus, trading as Sunplus Optimum Inc., is a newer brand targeting the North American, Latin American, and Caribbean markets, with a claimed global production footprint of 6.5 GW and distribution warehouses in California, New Jersey, and Texas. Sunplus markets its modules as built to Bloomberg Tier 1 standards and carries CSA/UL certification for the US market, but it does not appear on published BloombergNEF Tier 1 lists as of mid-2025. On institutional footprint alone, AKCOME's longer track record and prior Tier 1 accreditation give it a modest edge despite the 2024 delisting.

AKCOME's current lineup centers on TOPCon and HJT cell technologies. Its AK iTopper series uses TOPCon 182mm cells while the flagship AK iPower HJT series pushed into the 730 W range with 23.5% module efficiency before its listing was suspended in early 2025, reportedly due to website accessibility issues. Independent Australian reviewers place AKCOME toward the budget-to-mid tier, noting solid headline specs but limited real-world installer feedback. Sunplus Optimum offers TOPCon, shingled, and HJT modules in both all-black and dual-glass bifacial configurations, covering residential rooftops through utility-scale ground mounts. Its product range extends to 550 W bifacial models with N-type cells, and the brand's UL certification makes it a viable option for US installers seeking alternatives to the dominant Chinese Tier 1 names.

For a typical buyer in 2025, neither brand belongs in the same conversation as JinkoSolar, LONGi, or Trina Solar for large-scale projects where bankability and secondary-market liquidity matter most. For cost-sensitive residential or small commercial installations where a local distributor backs the warranty, either brand can be a reasonable choice. AKCOME's longer history and broader geographic presence give it a slight reliability edge; Sunplus's US distribution network and UL certification may make it more practical for North American buyers specifically. The two are broadly interchangeable in budget-tier residential contexts, and the decisive factor will usually be local installer support and panel availability rather than technology differentiation.
