## Summary

Heckert Solar is a German manufacturer founded in 2003, headquartered in Chemnitz, Saxony, with a second production facility in Langenwetzendorf, Thuringia. It is widely recognized as the last solar module producer maintaining fully domestic manufacturing in Germany, following the 2024 exits of Solarwatt and Meyer Burger from German production. Its combined manufacturing capacity stands at approximately 800 MWp per year. No BloombergNEF Tier 1 listing has been confirmed in available sources, consistent with its modest scale relative to multi-gigawatt Asian rivals, though it carries strong name recognition across European residential and commercial markets. AEET Energy Group GmbH is a German wholesaler and system integrator based in Bad Gandersheim that markets some own-brand modules alongside third-party products; independent review sources treat it primarily as a distributor rather than a dedicated manufacturer, and no Tier 1 standing has been identified for the brand. On institutional footprint, Heckert Solar holds the clearly stronger position.

Heckert Solar's portfolio covers three confirmed series: the NeMo range for residential and light commercial rooftops, the Apollon line featuring N-type TOPCon cells, and the Zeus glass-glass series suited to longer-life commercial and ground-mount deployments, with module efficiency reported between roughly 19.7% and 23.5%. The Zeus series carries up to a 30-year product and performance warranty, and the brand has collaborated with the Fraunhofer Institute for Solar Energy Systems on advanced rooftop module development. AEET's own-label panels are built on an older cell generation, with efficiency ratings in the 14% to 15.5% range and rated outputs predominantly below 300 Wp, placing them in the entry-level residential and small commercial segment.

For a typical buyer in 2025, Heckert Solar is the more substantive choice. Its verified domestic production, modern TOPCon cell technology, and extended warranty terms represent a clear step up in product maturity over AEET's distributor-led, older-specification lineup. Buyers who prioritize European provenance and long-term bankability will find Heckert Solar the more credible option.
