The company operates at a niche scale and does not appear on BloombergNEF's Tier 1 module manufacturer rankings. Its portfolio centers on modules in the 170-200 Wp range, a specification that reflects an older technology tier suited mainly to the domestic residential replacement and legacy retrofit market. Customer feedback on service and warranty responsiveness is mixed. Sunova Solar Technology, by contrast, is a Chinese manufacturer founded in 2016 and headquartered in Wuxi, Jiangsu, that had shipped a cumulative 7.1 GW of modules globally by the end of 2024. It operates 5.5 GW of module production capacity with a further 4.5 GW under construction, and has maintained BNEF Tier 1 bankability status continuously for over a year as of 2024. On institutional footprint, Sunova holds a decisive advantage. Sunova's current lineup spans both TOPCon and HJT cell technologies. Its TOPCon bifacial modules, showcased at Intersolar Europe with panel-level efficiencies reaching 22.9%, target residential rooftops, commercial installations, and utility-scale ground mounts. Its HJT series carries a 30-year linear power guarantee with very low annual degradation, making it appealing to buyers with long time horizons. ASM's assembled modules, based on available evidence, do not include TOPCon or HJT designs and are best suited to straightforward Australian rooftop applications where locally assembled product is a compliance or preference requirement. For a typical buyer in 2025, Sunova is the stronger default. It offers modern cell technology, verified bankability, a warranty infrastructure backed by multi-GW production scale, and global installation references. ASM retains a narrow role only for Australian buyers with a firm local-content requirement, and it cannot match Sunova on technology generation, bankability, or scale. \---LINKS--- \- https://www.pv-magazine.com/press-releases/sunova-solar-listed-as-tier-1-module-manufacturer-by-bnef/ \| Sunova Solar listed as Tier 1 module manufacturer by BNEF \| article \- https://www.pv-tech.org/sunova-presents-high-efficiency-topcon-module-at-intersolar/ \| Sunova presents high-efficiency TOPCon module at Intersolar \| article \- https://energypal.com/best-solar-panels-for-homes/sunova-solar-technology \| Sunova Solar Technology - EnergyPal Buyer Guide \| review \- https://www.enfsolar.com/asm \| ASM - Australian Solar Manufacturing Pty Ltd profile \| review Sources: \- \[Sunova Solar listed as Tier 1 module manufacturer by BNEF\](https://www.pv-magazine.com/press-releases/sunova-solar-listed-as-tier-1-module-manufacturer-by-bnef/) \- \[Sunova presents high-efficiency TOPCon module at Intersolar\](https://www.pv-tech.org/sunova-presents-high-efficiency-topcon-module-at-intersolar/) \- \[Sunova Solar Technology - EnergyPal Buyer's Guide\](https://energypal.com/best-solar-panels-for-homes/sunova-solar-technology) \- \[ASM - Australian Solar Manufacturing Pty Ltd\](https://www.enfsolar.com/asm) Written by claude-sonnet from the figures above. ## Other comparisons - [ASM vs A.B.
