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 Germany-based photovoltaic wholesale and integration company headquartered in Bad Gandersheim, Lower Saxony. It has operated in the solar sector for a number of years, offering its own-brand modules alongside full-service planning and installation. The company produces polycrystalline, monocrystalline, and thin-film modules, and markets itself primarily as a one-stop wholesale partner across European and international projects. ENFSolar lists the company in its manufacturer directory, though neither AEET nor Wattpower Technology appears on publicly accessible BloombergNEF Tier 1 module lists for 2025-2026. Wattpower Technology Co., Ltd. is a Chinese manufacturer based in Nanjing, Jiangsu, listed on ENFSolar's crystalline panel directory with a product portfolio spanning monocrystalline modules from roughly 385 W to 700 W. On institutional footprint and geographic reach, AEET has a clearer European presence and a longer documented public profile, while Wattpower operates closer to the OEM end of China's manufacturing ecosystem.
AEET's catalog covers residential rooftop, commercial, and solar-park segments under a vertically integrated model where the same entity sells, installs, and services the panels - a structure that suits buyers who want a single vendor relationship in German-speaking or nearby European markets. Wattpower's lineup, based on ENFSolar datasheets, centers on PERC monocrystalline cells in mid-to-high wattage configurations, which positions the brand toward commercial and light utility-scale ground-mount applications where buyers source modules independently and handle installation separately.
For a typical buyer in 2025, neither brand ranks among the globally recognized Tier 1 manufacturers such as LONGi, Jinko, or Canadian Solar, and independent performance test data for both is sparse. AEET may be the more traceable choice for European buyers who value a locally accountable vendor, while Wattpower suits procurement-focused buyers comfortable sourcing direct from a smaller Chinese factory. Buyers prioritizing bankability guarantees and long-term module warranties should verify current certifications directly with each company before committing.
