Rather than manufacturing panels itself, AEET operates as a full-service PV wholesale partner, sourcing modules from globally recognized manufacturers and supplying installers, investors, and operators primarily across European markets. Because it is a distribution company rather than a cell-and-module producer, AEET does not carry a BloombergNEF Tier 1 bankability rating of its own. Eco Delta Power Co., Ltd., by contrast, is a Chinese panel manufacturer based in Changzhou City, Jiangsu Province, with a reported annual module production capacity of approximately 3.2 GW and roughly 1,800 employees. Its products have reached more than 50 countries. No confirmed BloombergNEF Tier 1 listing has emerged for Eco Delta in publicly available sources, placing it in the mid-tier of Chinese manufacturers by institutional standing. In terms of manufacturing scale and production infrastructure, Eco Delta carries the stronger footprint. On the product side, AEET's catalog reflects whatever modules its supply partners offer at a given time - typically mainstream PERC and increasingly TOPCon panels sourced from established brands - making it better understood as a procurement channel than a distinct panel brand in its own right. Eco Delta manufactures a range that includes shingled crystalline silicon modules reaching up to around 480W, TOPCon-based products such as the ECO-440-450M-54LHC-DGBF series, and flexible modules suited to non-standard mounting configurations. Reported shingled module efficiency reaches approximately 20.9%. The company appears oriented toward residential and light commercial applications in export markets, with some older PERC lines no longer in production. For a project developer or installer selecting a panel brand in 2025, the comparison is inherently asymmetric. AEET is a procurement intermediary rather than a specification-ready brand, making it most relevant for European installers seeking supply-chain support. Eco Delta is a genuine GW-scale module producer, though buyers on financed projects should independently verify current bankability status before specifying it in lender documentation. \---LINKS--- \- https://www.enfsolar.com/aeet \| AEET Energy Group GmbH - ENF Solar industry directory profile \| article \- https://www.enfsolar.com/eco-delta \| Eco Delta Power Co., Ltd. - ENF Solar industry directory profile \| article \- https://energypal.com/best-solar-panels-for-homes/eco-delta-power \| Eco Delta Power buyer's guide - EnergyPal 2025 \| review \- https://www.enfsolar.com/pv/panel-datasheet/crystalline/61707 \| Eco Delta TOPCon module datasheet ECO-440-450M-54LHC-DGBF \| article Sources: \- \[AEET Energy Group GmbH - ENF Solar\](https://www.enfsolar.com/aeet) \- \[Eco Delta Power Co., Ltd. - ENF Solar\](https://www.enfsolar.com/eco-delta) \- \[Eco Delta Power buyer's guide - EnergyPal\](https://energypal.com/best-solar-panels-for-homes/eco-delta-power) \- \[Eco Delta TOPCon module datasheet\](https://www.enfsolar.com/pv/panel-datasheet/crystalline/61707) Written by claude-sonnet from the figures above. ## Other comparisons - [ECODELTA vs A.B.
