## Summary

AE Solar, operating formally as AE Alternative Energy GmbH and headquartered in Gersthofen, Bavaria, is a Germany-based solar brand with manufacturing spread across China, Georgia, and Turkey, giving it an annual production capacity of over 2 GW. The company has earned repeated inclusion on the BloombergNEF Tier 1 PV Module Manufacturer List - its sixteenth consecutive appearance was recorded in Q1 2025 - and Bloomberg identified it in 2024 as Europe's sole Tier 1 PV manufacturer carrying high bankability. DualSun is a French company founded in 2010 by Laetitia Brottier and Jerome Mouterde, headquartered in Marseille and specializing in hybrid photovoltaic-thermal (PVT) panels. Final assembly of its flagship product takes place at the Jujurieux plant in France, where more than half of the added value originates, allowing the panels to carry a "Made in France" label. However, DualSun's reserved production capacity is around 100 MW through an Austrian partner facility, well below the threshold for BloombergNEF Tier 1 recognition. On the dimension of institutional footprint and project-finance bankability, AE Solar holds a clear structural advantage.

AE Solar's lineup spans the Meteor series of N-type TOPCon bifacial modules covering residential through utility-scale ground-mount applications, the Comet HJT series reaching up to 23.05% module efficiency, and the Aurora PERC series available in mono- and bifacial configurations. The company carries a 30-year product warranty - well above the industry norm - and earned the PVEL Top Performer Award 2025 alongside a top rating in PV Magazine's module test. DualSun centers its commercial identity on the SPRING hybrid PVT panel, which simultaneously generates electricity from the front surface and captures usable heat from the rear, making it a strong fit for residential installations where hot water demand or pool heating can absorb the thermal output. A new pure-PV TOPCon line called AZUR is expected to become commercially available at the end of May 2026, which could extend DualSun's reach into more conventional PV procurement.

For a standard international buyer seeking bankable modules for residential, commercial, or utility-scale projects with no special thermal requirements, AE Solar is the more straightforward choice given its verified Tier 1 status, diverse technology portfolio, and established global distribution. DualSun is a well-justified but genuinely niche selection: it excels specifically in scenarios where simultaneous heat and power generation on a constrained roof area can displace a separate solar thermal system, reducing total energy costs in a way that a conventional PV panel simply cannot. The two brands are not interchangeable - they serve meaningfully different buyer profiles.
