## Summary

Hounen Solar is a US-assembled panel brand established in 2022 with a manufacturing facility in Orangeburg, South Carolina, currently operating at approximately 1 GW of annual production capacity and targeting 3 GW in the near term. The company is Chinese-backed but positions itself specifically around domestic US assembly, which shields buyers from import tariffs and qualifies projects for relevant domestic-content incentives. As of mid-2025, Hounen had not yet achieved BloombergNEF Tier 1 bankability status, though the company publicly stated a goal of reaching that designation by end of 2025. AKCOME - formally Jiangsu/Zhejiang Akcome New Energy Technology - is a substantially larger Chinese manufacturer listed on the Shenzhen stock exchange, with panel production capacity reported around 10 GW and cumulative shipments exceeding 15 GW by 2023. AKCOME held BloombergNEF Tier 1 status as recently as 2022 but was removed from that list in 2024. On sheer institutional scale and track record, AKCOME carries the broader footprint, though neither brand currently sits in the first tier of bankability.

Hounen Solar's catalog spans roughly 400W to 720W across residential, commercial, and utility-scale form factors, with PERC bifacial technology confirmed across its current US-assembled lineup. Its domestic production angle makes it a natural fit for US buyers navigating tariff exposure or pursuing IRA domestic-content adders. AKCOME's product range leans more heavily toward high-efficiency n-type technologies - the company has been developing HJT cells since 2012 and confirmed mass-production HJT cell efficiencies above 25.6%, and it also offers TOPCon bifacial modules. AKCOME targets commercial rooftop and utility-scale ground-mount applications globally, with a 30-year performance warranty backing its modules.

For a US-based buyer in 2025, Hounen Solar's domestic assembly is a concrete commercial advantage if tariff costs or content requirements are a factor. For international or utility-scale buyers who prioritize proven high-efficiency n-type technology and a longer shipping history, AKCOME's HJT and TOPCon offerings are more compelling - provided buyers account for its lapsed Tier 1 status when seeking project financing.
