AEET vs Powitt Solar - solar panel manufacturer comparison
Powitt Solar has the broader catalog (21 vs 5 models). Powitt Solar leads on peak efficiency at 23.69%. Powitt Solar leans bifacial (100% of lineup).
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
AEET Energy Group GmbH is a small German-registered manufacturer with a limited public profile and a portfolio of just five panel models; Powitt Solar is a Chinese producer based in Jiangsu province, founded around 2007, with an annual production capacity of approximately 1 GW and 21 catalogued models. Neither company currently holds Tier 1 bankable status from BloombergNEF, and neither appears on a major stock exchange. On institutional footprint alone, Powitt Solar carries more weight: it operates fully automated lines, exports globally, and has a documented product history spanning nearly two decades, while AEET remains largely opaque outside European ENF Solar directory listings.
The two portfolios differ sharply in every measurable dimension. AEET's lineup tops out at 200 Wp with an average of 190 Wp and a peak efficiency of 15.7% against an average of 14.9%; cell technology is unlisted, no bifacial models exist, and the product warranty runs 25 years. These figures place AEET squarely in legacy or budget-tier territory, suited at best to small off-grid systems or low-cost commercial retrofit projects where roof space is not a constraint. Powitt Solar's current range is built entirely around N-type TOPCon cells, is 100% bifacial, averages 636 Wp with a ceiling of 720 Wp, and delivers average module efficiency of 22.9% peaking at 23.69%. A low average temperature coefficient of -0.30%/degrees C and a 30-year product warranty round out a profile aimed squarely at utility-scale ground mounts and premium large-format commercial rooftops.
For a typical buyer in 2025, Powitt Solar is the clear default choice between these two. Its N-type bifacial panels deliver roughly 8 percentage points more efficiency and more than three times the watt-peak output of AEET's top model, which matters for both land-constrained and bankability-sensitive projects. AEET's portfolio reflects specifications from an earlier era of polycrystalline technology and is not competitive for any standard residential or commercial application at current market pricing. The two lineups do not overlap in any practical use case.
