## Summary

Solar-Fabrik is a German manufacturer with roots going back to 1996, when it was founded in Freiburg by solar pioneer Georg Salvamoser. After transitioning to a family-run operation in 2016, the company shifted module production to China in 2018 to reduce costs, but in May 2025 it broke ground on a new 300 MW domestic factory, with series production targeting autumn 2025 and a stated long-term expansion path toward 1 GW annually. Solar-Fabrik does not appear on current BloombergNEF Tier 1 lists, which reflects its comparatively modest production scale rather than any product deficiency. AIKO Solar, founded in 2009 and headquartered in China with multiple gigafactories across Yiwu, Foshan, Zhuhai, and Jinan, is a substantially larger operation: it achieved BloombergNEF Tier 1 status in Q3 2024 and by Q2 2026 was listed with annual capacity of roughly 35 GW, placing it inside the global top-ten ranked manufacturers. On institutional footprint, AIKO holds a clear advantage.

The two brands serve overlapping but distinct segments. Solar-Fabrik positions itself on the European premium market, emphasizing German-quality heritage, and its upcoming domestic factory will produce N-type TOPCon and heterojunction modules, making it a credible choice for buyers who prioritize locally manufactured product and long supply-chain accountability. It offers up to 30-year product and performance warranties. AIKO is best known for its proprietary N-type ABC (All Back Contact) cell architecture, which has delivered leading commercial module efficiencies confirmed at above 24% and has earned recognition from both pv magazine and the Intersolar Awards. Its Neostar series targets premium residential rooftops and commercial and industrial rooftops where high output per square metre justifies a price premium, and its 30-year performance warranty includes a tightly degradation rate of 0.35% per year after year one.

For most buyers in 2025, AIKO is the stronger default if efficiency and bankability are primary criteria, given its proven BloombergNEF standing, large installed base, and industry-leading ABC technology. Solar-Fabrik is the more defensible choice for European buyers who specifically need or prefer domestically manufactured modules - a consideration that is growing in relevance under EU content and supply-chain policies - provided they are comfortable with a smaller, less globally recognized brand.
