## Summary

AEET Energy Group GmbH is a German photovoltaic wholesale and specialist-partner network headquartered in Germany. Its primary role in the market is as a distribution and installation intermediary, spanning a certified partner network of more than 500 businesses across Germany rather than operating as a vertically integrated panel fabricator. Because of that positioning, AEET does not appear on BloombergNEF Tier 1 solar module lists, which track manufacturers that have supplied own-brand, own-manufactured modules to utility-scale bankable projects. Solar-Fabrik, by contrast, is a genuine German panel manufacturer founded in Freiburg im Breisgau in 1996. After a 2016 ownership change it has operated as a family-run business, leveraging more than 25 years of production heritage. Solar-Fabrik's modules are certified by TÜV Nord, and while the brand is not prominently cited on current BNEF Tier 1 rosters, it maintains an active product line sold primarily in the DACH region. On institutional footprint, Solar-Fabrik holds the clearer identity as a product manufacturer, whereas AEET is better understood as a trade and logistics partner.

Solar-Fabrik targets the residential and commercial-and-industrial rooftop segment with a range that historically covered both monocrystalline and polycrystalline formats. In September 2025 the company unveiled a back-contact solar module aimed at residential and C&I applications, signaling an ambition to move toward premium cell architectures. Its German-warranty offering covers 30 years on both product and performance for residential glass-glass modules, which is a meaningful differentiator in the European quality-conscious market. AEET Energy Group, as a wholesale partner, sources modules from multiple brands and does not publish a proprietary panel technology stack, so direct cell-technology comparisons are not meaningful.

For a buyer seeking a single branded solar panel with traceable German manufacturing heritage and a strong warranty commitment, Solar-Fabrik is the more coherent choice. AEET suits buyers looking for a turnkey supply-and-install channel that can bundle products from multiple sources with local service support. The two entities are not really interchangeable: one is a brand, the other is a distribution infrastructure.
