## Summary

Hounen Solar is a US-based manufacturer founded in 2022, operating an assembly facility in Orangeburg, South Carolina. The company has been targeting approximately 1 GW of annual production capacity and, as of late 2024, was actively working toward achieving Tier 1 bankability recognition - a milestone it had not yet formally reached. AEET Energy Group GmbH is a Germany-based wholesale and distribution company headquartered in Bad Gandersheim that sells own-branded photovoltaic modules alongside products from partners such as Suntech and CNPV. AEET has no publicly documented Tier 1 or BloombergNEF listing, and its scale is regional rather than global. In terms of institutional footprint, Hounen Solar - despite being a younger company - carries greater visibility in the North American utility and commercial market due to its domestic manufacturing credentials.

Hounen Solar's current catalog runs from roughly 400W residential modules up to 720W large-format commercial panels, with PERC bifacial technology confirmed in available product listings and HJT modules announced as a near-term addition. The company explicitly targets US residential rooftops, commercial and industrial (C&I) installations, and utility-scale ground mounts, and its US-assembled status offers buyers a tariff-compliance advantage. AEET's own-branded modules sit in the 270W to 300W range based on ENF Solar directory data - a more modest specification that reflects an older design generation - and the company's primary value proposition is its network of over 500 certified installer partners across Germany, making it essentially a regional European distribution channel rather than a frontline manufacturer.

For a buyer outside Germany evaluating the two on product generation, technology roadmap, and market transparency, Hounen Solar is the more credible default in 2025, particularly for North American projects where its domestic assembly directly reduces import-tariff exposure. AEET suits buyers already embedded in its German partner network who value local service support over cutting-edge module performance.
