Rather than fabricating its own panels, the company positions itself as a sourcing and distribution hub - procuring modules from a range of established manufacturers, maintaining a well-stocked warehouse, and deploying through a network of more than 500 TUV Rheinland-certified specialist partners. Because AEET does not produce panels under its own brand at scale, it does not appear on the BloombergNEF Tier 1 manufacturers list, which tracks module makers, not distributors. DualSun, by contrast, is an independent French manufacturer founded in Marseille in 2010, producing panels under its own brand. It is a relatively small, innovation-focused company compared with global volume leaders, and it similarly does not carry Tier 1 bankability status, but it has attracted meaningful institutional attention in the European residential and self-consumption market. Between the two, DualSun has the stronger identity as an actual product manufacturer. DualSun's catalog divides into two families with clearly different use cases. The FLASH line uses TOPCon cell technology with shingle interconnection and reaches confirmed panel efficiencies above 22 percent - targeting premium residential rooftops where aesthetics and long-term yield matter. The SPRING line is a certified hybrid PV-T (photovoltaic-thermal) panel that simultaneously generates electricity and heats water, making it relevant to homes combining solar power with domestic hot water or pool heating. The thermal assembly and final integration of SPRING panels are carried out at DualSun's plant in Jujurieux, France, giving it a "Made in France" label for that product. AEET, as a distributor, can supply mono and polycrystalline modules across a broader efficiency and price range depending on which manufacturing partners it contracts with, but that breadth is a function of its wholesale model rather than proprietary technology development. For a buyer in 2025 looking for an innovative, premium residential panel - especially one interested in hybrid solar-thermal technology - DualSun is the more distinctive choice. For a buyer in Germany seeking flexible sourcing, competitive bulk pricing, or turnkey project support across a range of module brands, AEET's wholesale-integrator model serves a different and valid purpose. The two brands operate in largely non-overlapping segments, so a direct like-for-like comparison is limited. \---LINKS--- \- https://www.enfsolar.com/aeet \| AEET Energy Group GmbH profile - ENF Solar directory \| article \- https://energypal.com/best-solar-panels-for-homes/aeet-energy-group \| AEET Energy Group - EnergyPal buyer's guide 2025 \| review \- https://energypal.com/best-solar-panels-for-homes/dualsun \| DualSun - EnergyPal buyer's guide 2025 \| review \- https://seize-sa.ch/en/dualsun-solar-panels-review/ \| Independent review of DualSun solar panels 2024 \| review \- https://strategicenergy.eu/dualsun-technology-panels/ \| DualSun hybrid panels and IoT self-consumption overview \| article Sources: \- \[AEET Energy Group GmbH - ENF Solar\](https://www.enfsolar.com/aeet) \- \[AEET Energy Group - EnergyPal\](https://energypal.com/best-solar-panels-for-homes/aeet-energy-group) \- \[DualSun - EnergyPal\](https://energypal.com/best-solar-panels-for-homes/dualsun) \- \[DualSun solar panels review - Seize-SA\](https://seize-sa.ch/en/dualsun-solar-panels-review/) \- \[DualSun hybrid panels - Strategic Energy Europe\](https://strategicenergy.eu/dualsun-technology-panels/) Written by claude-sonnet from the figures above. ## Other comparisons - [DualSun vs A.B.
