Rather than manufacturing panels under its own name, AEET acts as a full-service intermediary that sources modules from globally recognized producers and routes them through a network of more than 500 certified specialist partners across Germany. Because it is a trading and distribution business rather than a panel maker, it does not appear on BloombergNEF's Tier 1 manufacturer list, which is reserved for module producers. Fellow Energy is a vertically integrated solar manufacturer founded in 2020 in Gaziantep, Turkey, operating two production facilities that span wafer slicing, cell processing, and module assembly - making it one of the few fully integrated PV producers in the Europe-MENA region. Fellow Energy holds recognized Tier 1 bankability status, which gives it a meaningfully stronger institutional footprint in the eyes of project financiers. Because AEET distributes products from multiple manufacturers, its portfolio is flexible and can cover residential rooftops through to larger commercial applications depending on which brands it sources at any given time. Fellow Energy's own manufacturing focuses on modern technologies including TOPCon and bifacial monocrystalline formats with multi-busbar designs, suited to both residential and commercial installations. Given Turkey's position as the largest PV module producing country in the Europe-MENA region and Fellow Energy's fully domestic cell-to-module supply chain, the company is particularly well positioned for projects where European supply-chain provenance or local content requirements are a factor. For most buyers in 2025, Fellow Energy is the more verifiable choice when traceability of manufacture and Tier 1 bankability are priorities. AEET serves a genuine need as a convenient multi-brand wholesale channel in the German market, but buyers should independently confirm which manufacturer's panels AEET is supplying at the time of purchase, since underlying product quality and warranty terms will vary depending on the sourced brand. \---LINKS--- \- https://comparepv.com/reviews/fellow-energy \| Fellow Energy Solar Panels Review 2026 - ComparePV \| review \- https://www.enfsolar.com/aeet \| AEET Energy Group GmbH - ENF Solar manufacturer directory \| article \- https://energypal.com/best-solar-panels-for-homes/aeet-energy-group \| AEET Energy Group - EnergyPal buyer guide entry \| review Sources: \- \[Fellow Energy Solar Panels Review 2026 - ComparePV\](https://comparepv.com/reviews/fellow-energy) \- \[AEET Energy Group GmbH - ENF Solar\](https://www.enfsolar.com/aeet) \- \[AEET Energy Group - EnergyPal Buyer's Guide\](https://energypal.com/best-solar-panels-for-homes/aeet-energy-group) \- \[Fellow Energy - About Us\](https://fellowsolarenergy.com/about-us/) \- \[AEET Energy Group - Official Site\](https://www.aeet-energy.com/en/index.php) Written by claude-sonnet from the figures above. ## Other comparisons - [Fellow Energy vs A.B.
