The company operates at a modest volume suited to the Australian rooftop segment and does not appear on BloombergNEF's Tier 1 module list or any comparable bankability ranking. Thornova Solar, formerly operating under the Sunova Solar brand, is a Chinese-origin manufacturer with fabrication sites in Southeast Asia, including an Indonesian facility commissioned in late 2024 with approximately 2.5 GW of module capacity. Thornova achieved BloombergNEF Tier 1 status in August 2023 and was confirmed on the Q1 2026 Tier 1 list; it also received a B ranking in the PV Tech Bankability Report for Q4 2024 and placed thirteenth in Wood Mackenzie's H1 2024 Solar Module Manufacturer Ranking. By every institutional measure, Thornova carries a significantly stronger global footprint. On the product side, ASM's catalog has historically centered on lower-wattage monocrystalline panels suited to residential rooftops where local assembly and Australian compliance are priorities. Thornova, by contrast, offers a broad range spanning roughly 400 W to 720 W, built on N-type TOPCon bifacial cell technology, with efficiency figures that search results place between roughly 20.5% and 23.2%. Its lineup covers residential rooftops, commercial flat roofs, and utility-scale ground mounts, and it earned a Kiwa PVEL 2025 Top Performer designation for module reliability. Thornova has also established a US sales network with offices in Texas, Florida, New Jersey, and New York, signaling active pursuit of the North American market. For most buyers outside Australia, Thornova is the more practical default in 2025: it is bankable, independently tested, widely distributed, and built on proven N-type TOPCon technology at competitive wattages. ASM's appeal is narrower - buyers who specifically value Australian assembly and local after-sales support may find it worthwhile, but it cannot be compared to Thornova on scale, technology generation, or institutional credibility. \---LINKS--- \- https://www.pv-magazine.com/press-releases/thornova-solar-ranked-as-bnef-tier-1-module-manufacturer/ \| Thornova Solar ranked as BNEF Tier 1 module manufacturer \| article \- https://a1solarstore.com/blog/thornova-solar-panels-review-sharp-solutions.html \| Thornova Solar panels review 2026 - A1 SolarStore \| review \- https://www.thornova-solar.com/news/corporate-news/297.html \| Thornova Solar module receives Kiwa PVEL 2025 Top Performer award \| article \- https://www.thornova-solar.com/news/corporate-news/237.html \| Thornova Solar achieves B ranking in PV Tech Bankability Report \| article \- https://www.enfsolar.com/asm \| Australian Solar Manufacturing (ASM) - ENF Solar profile \| review Sources: \- \[Thornova Solar ranked as BNEF Tier 1 module manufacturer\](https://www.pv-magazine.com/press-releases/thornova-solar-ranked-as-bnef-tier-1-module-manufacturer/) \- \[Thornova Solar panels review 2026 - A1 SolarStore\](https://a1solarstore.com/blog/thornova-solar-panels-review-sharp-solutions.html) \- \[Thornova Solar module receives Kiwa PVEL 2025 Top Performer award\](https://www.thornova-solar.com/news/corporate-news/297.html) \- \[Thornova Solar achieves B ranking in PV Tech Bankability Report\](https://www.thornova-solar.com/news/corporate-news/237.html) \- \[Australian Solar Manufacturing (ASM) - ENF Solar profile\](https://www.enfsolar.com/asm) Written by claude-sonnet from the figures above. ## Other comparisons - [ASM vs A.B.
