Corab vs AEET - solar panel manufacturer comparison
Corab leads on peak efficiency at 21.00%.
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 to write the comparison.
Corab is a Polish solar manufacturer founded in 1993 with over 300 employees and a stated production capacity of 2.5 GW, giving it a solid industrial base in Central Europe. AEET Energy Group GmbH, headquartered in Germany, operates primarily as a photovoltaic wholesaler and distributor rather than a vertically integrated manufacturer; the company carries no Tier 1 bankability designation and reports no proprietary production capacity of its own. For institutional buyers or project financiers, Corab's manufacturing scale and three-decade track record place it in a meaningfully stronger position.
The two lineups occupy very different performance tiers. Corab's four-model portfolio averages 395 Wp and 20.5% efficiency, peaking at 410 Wp and 21.0% - figures consistent with modern monocrystalline cell technology and well suited to space-constrained residential or commercial rooftops where output per square metre matters. AEET's five panels average just 190 Wp and 14.9% efficiency, topping out at 200 Wp and 15.7%, numbers typical of older polycrystalline technology aimed at small off-grid or budget applications. Both brands carry a 25-year warranty and show no bifacial panels in the reviewed portfolios, but the wattage gap - roughly 2:1 in Corab's favour - makes direct substitution impractical for any standard grid-tied installation.
For a typical buyer in 2025 planning a residential or small commercial project, Corab is the clearer default. Higher wattage and efficiency translate to fewer panels for the same system output, and a 2.5 GW manufacturing base supports supply continuity in a way that a distributor-led brand cannot guarantee. AEET's low-power panels may serve a specific niche - small off-grid cabins, marine applications, or legacy retrofit work where 190-200 Wp modules are an exact-fit requirement - but for mainstream grid-connected solar the two are not meaningfully interchangeable.
