## Summary

AEET Energy Group GmbH is a German photovoltaic company headquartered in Bad Gandersheim, Germany, where it has operated as one of Europe's early solar wholesale and manufacturing specialists, maintaining production facilities in China for ingots, wafers, cells, and modules. It distributes through a network of more than 500 certified specialist partners across Germany and positions itself primarily as a European-market partner rather than a volume export brand. No BNEF Tier 1 bankability listing for AEET was found in available search results, which is consistent with its profile as a regional specialist rather than a global-scale volume supplier. Gamko New Energy - formally Nantong Gamko New Energy Co., Ltd. - is a Chinese manufacturer based in Nantong, Jiangsu, active in solar production since approximately 2008 and reporting annual output of around 1.2 GW as of 2023. Gamko likewise does not appear on publicly available BNEF Tier 1 module lists, placing both brands in a similar mid-market, non-bankability-rated tier. On sheer production scale and international distribution reach, Gamko holds the larger manufacturing footprint.

AEET's product catalog, as indexed on ENF Solar, centers on crystalline silicon modules suited to residential and small commercial rooftop installations in the European market, with the company serving primarily as a full-service wholesale partner rather than a high-volume OEM supplier. Gamko covers a notably wider wattage range - from compact 5W portable panels up to 800W large-format modules - and confirms both PERC and TOPCon cell technology across its lineup, along with bifacial and flexible variants, giving it broader applicability across residential, commercial, and light utility segments. Gamko holds a substantial certification portfolio including IEC 61215, IEC 61730, ISO 9001, and ISO 14001, and markets a 30-year product warranty, which is above average for a manufacturer in its tier.

For a typical European residential buyer in 2025, neither brand sits in the same league as BNEF Tier 1 names in terms of institutional bankability. Buyers who prioritize local European support infrastructure and a vetted installer network may find AEET's regional model advantageous. Buyers seeking broader module choice, higher wattage options, or competitive pricing on larger commercial or off-grid projects will likely find Gamko's wider catalog more flexible. Neither brand is a clear universal default - the better choice depends almost entirely on the installer relationship and regional availability.
