## Summary

AEET Energy Group GmbH is a German photovoltaic wholesale specialist headquartered in Bad Gandersheim, Lower Saxony. Rather than acting as a primary manufacturer, AEET functions as a full-service distributor, sourcing from leading global module makers - including First Solar - while also offering its own polycrystalline, monocrystalline, and thin-film modules. It maintains a network of more than 500 certified specialist partners across Germany. Solarwatt is one of Germany's oldest solar brands, founded in Dresden in 1993, and remains a recognised name in the premium residential segment across DACH markets. Neither company appears on the BloombergNEF Tier 1 bankability list - AEET because it operates chiefly as a distributor rather than a volume module producer, and Solarwatt because its premium niche positioning sits outside the utility-scale project finance market where Tier 1 status is most relevant. In terms of brand recognition and direct-consumer standing, Solarwatt carries the stronger institutional footprint.

AEET's catalog reflects its trade model: a broad selection of modules across power classes and technologies aimed at installers and developers who value procurement flexibility over a single technology commitment. Its own-brand modules carry a 10-year product warranty and a 25-year performance guarantee, broadly in line with market norms. Solarwatt focuses squarely on the premium residential rooftop segment, building its Panel vision line around TOPCon cell technology and a glass-glass construction it positions as more durable and crack-resistant than conventional glass-foil panels. Output reaches up to 450 Wp in the standard format and up to 620 Wp in the larger Panel vision XL variant, and all glass-glass modules are backed by a 30-year product and performance guarantee - among the longest available in the industry. It is worth noting that Solarwatt closed its 300 MW manufacturing plant in Dresden in 2024, shifting production to other facilities.

For homeowners and residential installers prioritising long-term durability and a strong direct-from-manufacturer warranty, Solarwatt is the more compelling choice in 2025, particularly in German-speaking markets where its brand and installer network are well established. AEET fits better as a sourcing partner for trade buyers - small installers or project developers - who need access to multiple brands and technologies through a single wholesaler. The two occupy different roles in the supply chain more than they compete head to head on product.
