It does not appear on any published BloombergNEF or comparable bankability list, and its geographic headquarters, founding date, and annual production scale remain unverifiable from available sources. Buyers should treat it as an unclassified, likely regional or emerging brand until independent certification data becomes available. The absence of third-party coverage makes a balanced head-to-head comparison difficult, and any specific figures would be invented rather than sourced. Tangra is the flagship module line of Thornova Solar, a company founded in Fremont, California, in late 2022. Despite its short history, Thornova reached BloombergNEF Tier 1 bankability status within its first year of operation - a rare achievement for a newly established entity. Thornova's Tangra series uses N-type TOPCon cell architecture in a bifacial, dual-glass construction, covering a power output range of roughly 400 W to over 700 W. The Tangra M PRO series earned Top Performer recognition from Kiwa PVEL across all seven of its reliability test categories and cleared an enhanced 40 mm hail stress test, which positions it competitively against established Chinese manufacturers on durability. In 2025 the Thornova brand and its intellectual property were acquired by ICE EYE, introducing some uncertainty about long-term supply continuity and corporate support structures. For a typical buyer in 2025-2026, Tangra panels carry more verifiable third-party validation than ASM panels do, making them the more bankable default where project financing or insurance is involved. If ASM is being considered for a small off-grid or residential installation where bankability is not a constraint, the lack of public data is less critical - but due diligence with the local distributor is strongly recommended before committing to that brand for any larger project. \---LINKS--- \- 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 Tangra M PRO earns Kiwa PVEL 2025 Top Performer award \| article \- https://www.renvu.com/blogs/learn/tier-1-solar-panels-list-2025-updated-manufacturers-rankings \| Tier 1 Solar Panels List 2025 - Updated Manufacturers and Rankings \| article Sources: \- \[Thornova Solar panels review 2026 - A1 SolarStore\](https://a1solarstore.com/blog/thornova-solar-panels-review-sharp-solutions.html) \- \[Thornova Solar Tangra M PRO earns Kiwa PVEL 2025 Top Performer award\](https://www.thornova-solar.com/news/corporate-news/297.html) \- \[Tier 1 Solar Panels List 2025 - Updated Manufacturers and Rankings - RENVU\](https://www.renvu.com/blogs/learn/tier-1-solar-panels-list-2025-updated-manufacturers-rankings) Written by claude-sonnet from the figures above. ## Other comparisons - [ASM vs A.B.
