## Summary

AIKO is a Chinese manufacturer that has risen rapidly to global prominence, achieving BloombergNEF Tier 1 bankability status in Q3 2024 and reporting an annual production capacity of around 20 GW as of early 2025. DualSun was founded in 2010 and is headquartered in Marseille, France, with a module factory in Jujurieux in eastern France; its annual output exceeds 100 MW, placing it firmly in the premium-niche rather than volume-producer tier. DualSun has not appeared on the BloombergNEF Tier 1 list, though it holds a strong domestic position as the reported leader in residential solar in France and counts Bpifrance and other institutional backers among its investors. On raw institutional scale, AIKO carries the considerably broader global footprint.

AIKO's product range centers on its proprietary ABC (All Back Contact) N-type cell architecture, which eliminates front-side metal contacts to maximize light capture; the company has reported mass-production module efficiencies reaching 24.8%, among the highest recorded commercially, and its panels are marketed for both premium residential rooftops and commercial installations where high power density matters. DualSun addresses a different segment with two complementary lines - the FLASH series of shingle-cell TOPCon photovoltaic modules targeting residential self-consumption, and the SPRING hybrid PVT panels that generate both electricity and hot water simultaneously from the same roof surface, making them especially well suited to households with significant domestic hot-water demand. A plug-and-play PREASY kit rounds out the range for simpler installations.

For a buyer whose priority is raw electrical output on a constrained roof area, AIKO's ABC technology and bankable scale make it a compelling default in 2025. DualSun is the better fit for European homeowners - particularly in France - who want to maximize total energy yield by combining PV and thermal output from a single rooftop, or who value locally manufactured, low-carbon-certified products. The two brands are not directly interchangeable: AIKO competes on efficiency leadership at volume, while DualSun occupies a differentiated hybrid-energy niche.
