## Summary

AKCOME is a Chinese manufacturer founded in 2006 as Jiangsu Akcome Science and Technology Co., Ltd., listed on the Shenzhen Stock Exchange in 2011 and later reorganized as Zhejiang Akcome New Energy Technology Co., Ltd. The company held an annual PV module production capacity of approximately 3.8 GW and was included on the BloombergNEF Tier 1 list as recently as Q4 2023. In mid-2024, however, a court ordered one of its subsidiaries into reorganization proceedings after creditors declared it unable to meet its obligations. The parent company had reported net losses every year since 2019, and its shares were subsequently delisted from the Shenzhen Stock Exchange after trading below 1 yuan for 20 consecutive sessions. AKCOME does not appear on the BNEF Tier 1 list for any quarter in 2025. DAH Solar, founded in 2009 as Anhui Daheng Energy Technology Co., Ltd. and headquartered in Hefei, Anhui province, operates with an annual TOPCon module capacity of up to 10 GW and has maintained a continuous presence on the BloombergNEF Tier 1 list, with confirmation in both Q1 and Q3 2025. In terms of financial stability and current institutional footprint, DAH Solar holds a considerably stronger position.

AKCOME built its technical identity around heterojunction technology (HJT), differentiating itself in a market increasingly converging on TOPCon. Its modules operated in the 655 W to 700 W power range, with average efficiencies of around 21.6% and flagship models reaching 22.5%. HJT's favorable temperature coefficient made these panels well-suited for high-irradiance environments and space-constrained rooftop applications. DAH Solar's portfolio is centered on TOPCon, and its most distinctive offering is the patented Full-Screen PV Module - a frameless design protected by patents in over 18 countries, claimed to improve energy yield by 6-15% compared with conventional framed modules. The company also provides integrated solar systems and energy storage solutions, making it competitive across residential rooftops, commercial and industrial installations, and utility-scale ground-mount projects.

For most international buyers today, DAH Solar is the more defensible procurement choice: it offers verified Tier 1 bankability in 2025, a larger and operational supply chain, and no outstanding insolvency concerns. AKCOME's HJT focus was a genuine technical differentiator, but given the documented bankruptcy proceedings and exchange delisting in 2024, warranty coverage and long-term after-sales support are in serious doubt - conditions that most project financiers and professional installers will find unacceptable. Buyers specifically seeking HJT technology would be better served by other manufacturers in that segment with intact financial standing.
