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
AIKO is a Chinese solar manufacturer that achieved BloombergNEF Tier 1 bankability status in Q3 2024, placing it among the small fraction of global solar brands recognized for project-finance credibility by commercial lenders. By early 2025 the company had built out a production capacity reported at approximately 20 GW per year. AEET Energy Group GmbH is registered in Germany and describes itself primarily as a photovoltaic wholesale partner with manufacturing operations in China; no appearance on BloombergNEF or equivalent Tier 1 bankability lists was found during research, and no verified annual production figure has been publicly reported. On institutional footprint and third-party recognition, AIKO holds the considerably stronger position.
AIKO has built its reputation on ABC (All Back Contact) cell technology, which eliminates front-side metallization to raise module efficiency. Independent reviewers in 2025 consistently place AIKO panel efficiencies above 23 percent, and the company has reported a mass-production world-record result of 24.4 percent. Its product line targets premium residential and commercial rooftop installations where limited roof area makes per-watt yield critical, supported by a 30-year performance warranty with a stated annual degradation rate of 0.35 percent after year one - a figure that contributed to AIKO winning first place in the 2025 SolarQuotes Installers' Choice Awards in Australia. AEET, by contrast, offers a broader catalogue that spans polycrystalline, monocrystalline, and thin-film modules, a range more consistent with positioning across budget commercial and specialist niche segments than a single high-efficiency premium tier.
For a typical 2025 buyer who values verified bankability, independently tested efficiency, and long-term warranty support, AIKO is the clearer default. AEET may suit buyers seeking a European-registered wholesale partner for a varied technology mix, but the absence of Tier 1 credentials and published independent benchmarks makes a direct performance comparison difficult, and prospective buyers should request project references and third-party test data before committing.
