The company assembles panels using components sourced from Germany, Japan, the United States, and China rather than manufacturing cells or wafers in-house. It does not appear on any BloombergNEF Tier 1 bankability list, and its production scale is modest compared to global benchmark manufacturers. DualSun, by contrast, is a French manufacturer founded in 2010 by engineers from Ecole Centrale Paris and headquartered in Marseille, with a module factory in Jujurieux in eastern France. The company has grown to become the residential solar market leader in France with over 100,000 rooftops equipped, and it maintains an active profile in the European renewable-energy press. On institutional footprint and market recognition, DualSun clearly has the stronger standing. ASM's catalog centers on monocrystalline panels in a relatively modest wattage range that reflects older design generations, making the brand most relevant to buyers seeking a locally assembled product in the Australian market rather than cutting-edge cell technology. DualSun offers two distinct product families: the FLASH series, which uses shingle cell architecture built on TOPCon cells and targets premium residential and light commercial rooftops, and the SPRING series, a hybrid photovoltaic-thermal panel that simultaneously generates electricity and heats water. The SPRING panels have been validated in independent testing by French research institutes CEA and INES for best-in-class thermal performance. Both product lines carry a product guarantee of 25 years plus an extended performance warranty. For a buyer outside of Australia seeking a premium residential installation in 2025, DualSun is the more compelling default, particularly where water-heating demand is high and the hybrid SPRING panel can displace a conventional hot-water system. ASM is a reasonable choice only when local Australian assembly is a procurement requirement; beyond that specific context, its technology and bankability profile lag behind DualSun and many other mainstream brands. \---LINKS--- \- https://www.solarfeeds.com/biz/australian-solar-manufacturing-pty-ltd/ \| Australian Solar Manufacturing Company Overview - Production Capacity, Is it Tier1? \| article \- https://dualsun.com/en/guides/solar-panel/advantages-shingle-panels/ \| Advantages of Dualsun FLASH and SPRING Shingle panels - 2025 \| article \- https://www.pv-magazine.com/2024/04/24/dualsun-launches-foldable-plug-and-play-solar-kits/ \| DualSun launches foldable plug-and-play solar kits - pv magazine \| article \- https://dualsun.com/en/guides/news/study-comparing-pv-t-modules-shows-that-dualsun-panels-have-the-best-thermal-performances/ \| Study shows Dualsun panels have the best thermal performances \| article \- https://energypal.com/best-solar-panels-for-homes/dualsun \| DualSun - Best Solar Panels for Homes 2025 - EnergyPal Buyer's Guide \| review Sources: \- \[Australian Solar Manufacturing Company Overview\](https://www.solarfeeds.com/biz/australian-solar-manufacturing-pty-ltd/) \- \[Advantages of Dualsun FLASH and SPRING Shingle panels\](https://dualsun.com/en/guides/solar-panel/advantages-shingle-panels/) \- \[DualSun launches foldable plug-and-play solar kits - pv-magazine\](https://www.pv-magazine.com/2024/04/24/dualsun-launches-foldable-plug-and-play-solar-kits/) \- \[Study shows Dualsun panels have the best thermal performances\](https://dualsun.com/en/guides/news/study-comparing-pv-t-modules-shows-that-dualsun-panels-have-the-best-thermal-performances/) \- \[DualSun - Best Solar Panels for Homes 2025 - EnergyPal\](https://energypal.com/best-solar-panels-for-homes/dualsun) Written by claude-sonnet from the figures above. ## Other comparisons - [ASM vs A.B.
