## Summary

AE Solar was founded in 2003 by Alexander Maier in Königsbrunn, Germany (now headquartered in Gersthofen) and has grown from a family business into a globally active PV module manufacturer with a presence in over 100 countries. The company operates manufacturing facilities in China, Georgia, and Turkey, and reports an annual production capacity of approximately 2.5 GW. Its institutional standing is well-documented: BloombergNEF has included AE Solar in its Tier 1 list for 16 or more consecutive quarters, and the 2024 BNEF bankability survey ranked it 18th out of 67 evaluated manufacturers, identifying it as the sole European Tier 1 producer with high bankability - a rating that climbed from 26% in 2023 to 50% in 2024. Solar-Fabrik has a more turbulent history: the original company was founded in 1996 in Freiburg im Breisgau, Germany, declared bankruptcy in 2015, and was subsequently revived under new ownership. The current Solar-Fabrik GmbH broke ground on a new TOPCon module factory in Hösbach near Aschaffenburg in May 2024, targeting approximately 300 MW of annual capacity, with production scheduled to begin in autumn 2025 and a Future Campus training center opened at the site in January 2026. In July 2024 the company's CEO was arrested in connection with a customs investigation, adding legal uncertainty to an already nascent manufacturing ramp-up. AE Solar holds the considerably stronger institutional and bankability footprint of the two.

AE Solar's product portfolio centers on two main families: the Aurora series using P-type PERC technology and the Meteor series using N-type TOPCon cells, covering residential rooftop installations through to commercial and industrial C&I projects. PV Magazine awarded the company's N-type TOPCon modules a five-star rating in performance testing, and AE Solar holds DIBt certification - the first Tier 1 manufacturer to do so according to the company. Solar-Fabrik positions its offering around a "Made in Germany" quality narrative, with the planned Hösbach modules based on bifacial N-type TOPCon technology in a glass-glass format, targeting the premium end of the European residential and C&I market. However, since domestic production had not yet fully commenced as of early 2026, modules sold under the Solar-Fabrik brand in the recent period were largely sourced from Asian supply chains.

For international buyers, AE Solar is the lower-risk choice given its established track record, verified Tier 1 status, broad distribution network, and documented bankability with financiers and insurers. Solar-Fabrik's "Made in Germany" ambition may appeal to buyers with a strong preference for European manufacturing, but the unresolved legal situation around its leadership and the early stage of its production ramp make due diligence especially important before committing to large volumes.
