Rather than manufacturing its own solar panels, AEET sources modules from major global producers and resells them through a network of more than 500 certified specialist partners across Germany. It does not hold Tier 1 or BloombergNEF bankability status as a manufacturer, since that designation applies to panel makers rather than distributors. AU Optronics (AUO), by contrast, is a Taiwanese corporation headquartered in Hsinchu, originally established as a leading flat-panel display maker and now operating a dedicated solar energy division. BNEF has recognized AUO as a Tier 1 PV module manufacturer, and EuPD Research has repeatedly awarded it Top Brand PV status, giving AUO the considerably stronger institutional manufacturing footprint between the two. Because AEET is a distributor rather than a producer, its panel lineup at any given time reflects the portfolio of its supply partners rather than a proprietary technology roadmap. AUO, on the other hand, manufactures its own modules, most notably the SunAlto series - a large-format M10 dual-glass bifacial module featuring n-type TOPCon cells with reported average cell efficiencies around 25.5%, rated at approximately 490 W. AUO also operates a 150 MW module factory in Brno, Czech Republic, giving it a local-production foothold in the European market. Its panels are certified by the California Energy Commission for the US market and are suited primarily to commercial rooftop and utility-scale ground-mount applications. For a buyer seeking a bankable, technology-traceable panel brand with a defined manufacturing pedigree, AUO is the more substantive choice. AEET, however, serves a different role: it is best understood as a procurement and project-services partner for installers in the German market, potentially reselling AUO or other Tier 1 modules alongside its planning and maintenance services. Comparing them as competing panel suppliers is therefore not quite an apples-to-apples exercise. \---LINKS--- \- https://www.pv-magazine.com/2024/10/10/au-optronics-sas-win-pv-awards-in-taiwan-for-high-efficiency-module/ \| AU Optronics wins Taiwan PV award for high-efficiency TOPCon module \| article \- https://www.solarfeeds.com/biz/au-optronics/ \| AUO company overview - Tier 1 status and production profile \| review \- https://www.enfsolar.com/aeet \| AEET Energy Group GmbH profile - ENF Solar database \| review \- https://www.pv-magazine.com/press-releases/auo-pv-modules-approved-by-cec-for-expansion-into-us-market\_10002678/ \| AUO PV modules approved by CEC for US market expansion \| article Sources: \- \[AU Optronics, SAS bet on larger, high-efficiency solar modules - pv magazine\](https://www.pv-magazine.com/2024/10/10/au-optronics-sas-win-pv-awards-in-taiwan-for-high-efficiency-module/) \- \[AUO Company Overview - Tier 1 status\](https://www.solarfeeds.com/biz/au-optronics/) \- \[AEET Energy Group GmbH - ENF Solar\](https://www.enfsolar.com/aeet) \- \[AUO PV modules approved by CEC for US market\](https://www.pv-magazine.com/press-releases/auo-pv-modules-approved-by-cec-for-expansion-into-us-market\_10002678/) \- \[AEET Energy Group GmbH - Your photovoltaic wholesale partner\](https://www.aeet-energy.com/en/index.php) Written by claude-sonnet from the figures above. ## Other comparisons - [AU Optronics vs A.B.
