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
Heckert Solar is a German manufacturer based in Langenwetzendorf, Thuringia, and is widely recognized as one of the last companies still producing solar modules on German soil at meaningful scale. Its current annual output stands at roughly 800 MWp, with a publicly announced expansion targeting 2.8 GW across multiple sites. AEET Energy Group GmbH, also registered in Germany - in Bad Gandersheim, Lower Saxony - operates primarily as a photovoltaic wholesale partner rather than a vertically integrated manufacturer; it sources modules from established global suppliers and markets them under its own brand alongside third-party product lines. Neither company appears on publicly available BloombergNEF Tier 1 lists, which are dominated by large-scale Asian and select European volume producers. In terms of institutional footprint, Heckert carries meaningfully more brand recognition among European installers and has received consistent independent press coverage.
Heckert's catalog spans three main product families. The NeMo line is made entirely in Germany and targets the residential and small commercial segment. The Apollon series uses n-type TOPCon cell technology for buyers seeking higher efficiency in space-constrained rooftop installations. The Zeus series features glass-glass construction suited to flat roofs and commercial ground mounts, with select models carrying a 30-year product and performance warranty - well above the industry norm. AEET's own-branded modules are less distinctly positioned in publicly available sources; the company's materials emphasize wholesale availability and a broad portfolio of partner brands rather than a proprietary technology stack, and no confirmed cell technology for its house-brand panels was found in independent reviews.
For a typical European buyer in 2025, Heckert is the clearer choice when provenance, warranty depth, and traceable German manufacturing matter. AEET may suit installers seeking flexible wholesale sourcing, but it is not straightforwardly comparable as a peer manufacturer - the two occupy meaningfully different positions in the supply chain.
