AEET vs Tesla - solar panel manufacturer comparison
AEET has the broader catalog (5 vs 0 models).
Both catalogues are read from the manufacturers' own datasheets. A brand is not scored against the market here, only against the other brand on this page.

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
Now I have enough information to write the comparison.
Tesla, headquartered in the United States and listed on the NASDAQ, traces its corporate founding to 2003 and employs more than 100,000 people globally. Its solar panel business grew largely through the 2016 acquisition of SolarCity, and today Tesla Energy markets residential panels and roof tiles primarily as part of an integrated home-energy system anchored by the Powerwall battery. AEET Energy Group GmbH is a German-based solar wholesale and distribution company rather than a vertically integrated panel fabricator - it curates and resells modules from third-party OEM suppliers and is not listed on any stock exchange. Neither company appears on the current BloombergNEF Tier 1 bankable module manufacturer list, though Tesla's scale and brand recognition give it a far stronger institutional and consumer footprint than AEET's regional wholesale operation.
The available portfolio data tells a stark story about each company's product lineup. Tesla's aggregated panel statistics are incomplete in the source database, but independent reviews consistently place its standard residential module at roughly 400 Wp with efficiencies between 19 and 20 percent - an all-black monofacial format aimed squarely at premium residential rooftops, backed by a 25-year performance warranty. AEET's catalogued portfolio of five panels averages just 190 Wp at 14.9 percent efficiency, peaking at 200 Wp and 15.7 percent, with no bifacial panels and an unspecified cell technology - figures that reflect older polycrystalline-era specifications. AEET carries a 25-year average warranty across its small range, which is standard, but the low output density makes its panels better suited to cost-sensitive European buyers with ample roof space than to installations where efficiency per square metre matters.
For a typical buyer in 2025, Tesla is the stronger default if the goal is an integrated North American residential system with battery backup. AEET's modest 190-200 Wp range and non-Tier 1 status make it a poor fit for any project where lender bankability or high power density is a factor. Buyers prioritising leading-edge efficiency or utility-scale finance should look beyond both companies to dedicated module manufacturers with proven Tier 1 credentials.
