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, operating through AEET Energy Group and its manufacturing arm AE Solar, is a German company founded in Königsbrunn, Bavaria in 2003, with production facilities in China, Georgia and Turkey and a combined annual capacity of roughly 2.5 GW. The company has been named a BloombergNEF Tier 1 PV module manufacturer for five consecutive years as of the first quarter of 2026, its 17th such recognition since first qualifying in 2021, reflecting a solid banking and project-financing track record. SpolarPV, by contrast, is a Chinese manufacturer based in Nanjing, Jiangsu Province, founded in 2010, with a considerably smaller stated production footprint of around 800 MW annually and a sales network spanning over 50 countries; no BloombergNEF Tier 1 listing or major independent review coverage for the brand turned up in available sources. On institutional footprint, AEET holds the clearer edge, with a longer verified bankability history and larger, more geographically diversified manufacturing base.

Product-wise, AEET markets a broad module lineup including mono- and poly-crystalline and bifacial panels aimed at both residential rooftop and commercial/utility-scale installations across Europe, the Middle East and beyond, leveraging its European headquarters for CE-market credibility. SpolarPV positions itself primarily as an OEM/ODM supplier, offering N-type TOPCon modules, including MBB (multi-busbar) and dual-glass configurations, in power classes from roughly 430 W to 700 W, generally serving private-label and export customers such as distributors and system integrators building commercial or BIPV projects rather than end consumers directly.

For a typical buyer in 2025 prioritizing bankability, warranty confidence and traceable project financing, AEET is the safer default given its sustained Tier 1 status and longer operating history. SpolarPV can be a reasonable option for buyers seeking TOPCon technology through an OEM relationship or private-label sourcing, but its lack of independent Tier 1 confirmation and limited third-party review coverage mean it carries more due-diligence risk and is better suited to sourcing-savvy commercial buyers than residential consumers.
