It serves a niche domestic audience that values locally assembled hardware. ASM does not appear on BloombergNEF Tier 1 bankability lists, and its production scale remains modest compared with mainstream global suppliers. Sunman, by contrast, was founded in 2014 in China by Dr. Zhengrong Shi, the industry veteran who previously built Suntech into one of the world's largest solar companies. Sunman opened a 1 GW manufacturing facility in Jiangsu province in 2022, has shipped more than 600 MW of modules to over 40 countries, and in late 2025 secured AUD 171 million in Australian federal and state government funding to build a 500 MW plant in New South Wales. Sunman is also not currently ranked on the BloombergNEF Tier 1 list, but its international project pipeline and government-backed expansion give it a considerably stronger institutional footprint than ASM. The two brands occupy very different product niches. ASM produces conventional crystalline-silicon modules targeted at Australian residential and small commercial rooftop customers who prioritize local assembly provenance; specific cell technology confirmations are not available from independent sources. Sunman's entire product strategy is built around its proprietary eArc technology, a glass-free polymer-composite module that weighs roughly 70 percent less than a standard glass panel and can conform to curved surfaces. This makes eArc panels the go-to choice for weight-sensitive applications such as heritage buildings, vessel hulls, vehicle rooftops, and industrial shed roofs that cannot support conventional glazed modules. Sunman offers a 12-year product warranty and 25-year power performance warranty on its eArc line. For a typical buyer in 2025, the two brands are not meaningfully interchangeable. If the project is a standard Australian rooftop with normal structural capacity, both are viable but most installers would recommend higher-volume Tier 1 brands ahead of either. Where Sunman genuinely stands out is in lightweight or curved-surface deployments, where its eArc modules have no equivalent from ASM. ASM's value proposition rests almost entirely on Australian assembly origin, which matters to buyers with local-content requirements but is a narrow differentiator otherwise. \---LINKS--- \- https://www.pv-magazine.com/2022/01/12/sunman-opens-1gw-lightweight-pv-module-factory/ \| Sunman opens 1 GW lightweight PV module factory \| article \- https://www.pv-magazine.com/2025/12/02/sunman-to-build-500-mw-solar-panel-manufacturing-plant-in-australia/ \| Sunman to build 500 MW solar panel plant in Australia \| article \- https://www.cefc.com.au/case-studies/sunman-flexible-earc-technology-a-solar-revolution/ \| CEFC case study - Sunman flexible eArc technology \| article \- https://www.solarquotes.com.au/panels/sunman-energy-review.html \| Sunman Energy solar panels review - SolarQuotes \| review \- https://www.solarchoice.net.au/products/panels/sunman-earc-solar-panels-review/ \| Sunman eArc solar panels independent review - Solar Choice \| review Written by claude-sonnet from the figures above. ## Other comparisons - [ASM vs A.B.
