Catalogue against catalogue
An average over a catalogue describes the range a manufacturer publishes, not the module you would buy. A brand with two flagship panels and eighty older ones averages worse than one that has retired its back catalogue.

Written summary
TN Solar Co., Limited is a Chinese photovoltaic manufacturer founded in 2006 and headquartered in China, operating a production facility exceeding 100,000 square meters. The company carries ISO 9001 certification alongside CE and TUV marks, covering an integrated production chain that spans silicon ingots and wafers through to finished modules. No independent BloombergNEF Tier 1 bankability listing for TN Solar was found in available sources. AEET Energy Group GmbH is a Germany-based company headquartered in Bad Gandersheim that operates primarily as a photovoltaic wholesale and distribution partner, sourcing modules from established manufacturers and selling a portion under its own brand. AEET holds TUV Rheinland certification and markets its branded modules with a 10-year product warranty and a 25-year performance guarantee, but no BloombergNEF Tier 1 status was confirmed for it either. Of the two, TN Solar has the stronger claim to being an actual manufacturing entity with its own production assets.
TN Solar's catalog is oriented around smaller specialty panels in the 20-200 W range - suited to off-grid, marine, and portable applications - while also extending into mainstream residential and commercial modules in the 400-755 W class using PERC, TOPCon, and HJT cell technologies. AEET Energy Group, by contrast, positions itself explicitly as a full-service wholesale partner; its own-brand module line appears to complement a broader services offering rather than anchor a dedicated manufacturing programme, making it a better fit for European project developers seeking a single-source procurement and consultancy arrangement.
For a buyer primarily focused on module procurement at volume, TN Solar's manufacturing footprint gives it more transparency around production origin and cell technology. AEET Energy Group may suit European installers who value regional support and a single partner for supply, financing, and project services, but buyers requiring deep technical datasheets and bankable references from a dedicated factory would be better served by TN Solar or one of the established Tier 1 brands AEET itself distributes.
