## Summary

AKCOME, founded in 2003 and headquartered in China, operates a 6 GW panel factory in Huzhou, Zhejiang, and has built its identity entirely around heterojunction (HJT) cell technology. The company was previously recognized as Tier 1 by BNEF but lost that designation by early 2025 and was concurrently delisted from major module tracking indices due to website inaccessibility - a meaningful institutional red flag. Haitai Solar, founded three years later in 2006 and also China-based, carries a significantly stronger institutional profile: it completed its IPO on the Beijing Stock Exchange in August 2022, holds current BNEF Tier 1 bankability status, employs between 1,001 and 5,000 staff, and reports a declared production capacity of 10 GW. For project developers requiring lender acceptance, Haitai Solar's bankability gives it a clear advantage.

On portfolio character, the two companies diverge in scope and technology. AKCOME's catalogue of three products is narrow and high-power, averaging 671.7 Wp with a maximum of 700 Wp, at an average efficiency of 21.63% and a peak of 22.54%. Its HJT architecture delivers a notably favourable average temperature coefficient of -0.24%/°C, which translates to better real-world energy yield in warm climates. Every panel in the lineup is bifacial. Haitai Solar offers a far broader 16-panel portfolio that spans a wider power range, averaging 526.9 Wp and topping out at 720 Wp, with an average efficiency of 21.75% and a best-in-portfolio figure of 23.2%. Roughly 56% of Haitai's range uses N-type TOPCon cells, and its average temperature coefficient sits at -0.276%/°C - less competitive than AKCOME's HJT on that metric. Both manufacturers offer 100% bifacial panels and a 30-year product warranty. Haitai's broader range suits buyers from premium residential rooftops to utility-scale ground mounts, while AKCOME's high-wattage HJT panels target large-footprint commercial or utility installations where superior temperature performance matters.

For a typical buyer in 2025, Haitai Solar is the more defensible default. Its Tier 1 bankability status makes project financing straightforwardly cleaner, its portfolio breadth gives installers and developers more sizing flexibility, and its public listing provides a degree of financial transparency. AKCOME's HJT technology is genuinely superior on temperature coefficient and could be the right call in hot climates where that edge compounds over the system lifetime - but the loss of Tier 1 recognition introduces supply and warranty-backstop uncertainty that most buyers will reasonably want to avoid until the situation clarifies.
