## Summary

HD Solar and AIKO represent two very different tiers of market presence. AIKO was founded in 2009, is headquartered in China, and trades on the Shenzhen Stock Exchange (SZSE). It has achieved BloombergNEF Tier 1 bankable status - a designation held by roughly the top 2% of the roughly 17,000 solar manufacturers worldwide - and operates six major production facilities, having shipped more than 2 GW in Q1 2025 alone. HD Solar, by contrast, carries no Tier 1 bankable classification, has no disclosed founding date, stock exchange listing, or verifiable production-capacity figure, and its catalogue spans just 7 panel models. For any project requiring lender approval or long-horizon warranty security, AIKO has a materially stronger institutional footprint.

On paper performance, the two lineups overlap but diverge in character. HD Solar runs an entirely TOPCon, 100% bifacial portfolio averaging 620 Wp and 23.0% efficiency, peaking at 635 Wp and 23.5%, with a temperature coefficient of -0.30%/degree C and a 30-year product warranty - a clean, uniform offering suited to utility-scale ground mounts or large commercial rooftops where bifacial gain and predictable spec sheets matter. AIKO leans on its proprietary ABC (All Back Contact) cell architecture, which underpins about 74% of its 144-model range and drives a higher average efficiency of 23.7% and a best-in-class peak of 25.2%, with a milder temperature coefficient of -0.27%/degree C and a maximum panel output of 805 Wp. Only 24% of AIKO's portfolio is bifacial, however, so buyers seeking rear-side gains across the whole product range will find HD Solar a simpler match. AIKO's warranty averages 29.5 years - marginally shorter than HD Solar's uniform 30-year commitment.

For a typical buyer in 2025, AIKO is the more defensible default: the Tier 1 rating reduces financing friction, the ABC technology leads commercial silicon efficiency benchmarks, and the large installed base provides real-world performance data. HD Solar's fully bifacial, all-TOPCon lineup is technically coherent and carries a slightly longer warranty, but the absence of Tier 1 bankability is a meaningful risk for financed or large-scale projects. For smaller cash-purchased installations where bankability is irrelevant, the two lineups are closer - though AIKO's efficiency edge and broader module range still give it the advantage.
