Thornova holds a B-rating in the PV Tech Bankability Report as of Q4 2024 - a credible mid-tier bankability indicator - and its Tangra M PRO line earned Kiwa PVEL Top Performer recognition across all seven reliability test categories in the 2025 scorecard, a meaningful third-party quality endorsement. In 2025 the Tangra brand and associated intellectual property were acquired by ICE EYE, so buyers should monitor how product support and warranty obligations are honoured under the new ownership. AKCOME, by contrast, is a well-established Chinese manufacturer headquartered in Suzhou, Jiangsu Province, founded in 2006 and publicly listed in China since 2010. It holds BloombergNEF Tier 1 status, the most widely recognised bankability benchmark for project finance, operates in more than 30 countries, and owns over 1.5 GW of solar farms across the Asia-Pacific. On institutional footprint, AKCOME carries the stronger position. Both companies are committed to N-type cell technology. Thornova's Tangra M PRO is a bifacial dual-glass module aimed at commercial and utility-scale deployments where third-party reliability certification matters to lenders. AKCOME has positioned itself around heterojunction (HJT) technology - one of the more advanced N-type approaches - with planned cell capacity of 8.8 GW and module capacity of 4 GW at its Changxing facility. AKCOME also offers a 30-year performance warranty, which is notably longer than the industry norm of 25 years, making it a reasonable fit for utility developers who require long-horizon bankability alongside hardware performance. For a typical commercial or utility buyer in 2025, AKCOME is the more straightforward default: it combines verified BNEF Tier 1 bankability, a strong HJT technology roadmap, long warranty terms, and an established global presence. Tangra's PVEL Top Performer certification gives it genuine technical credibility, but the brand's mid-tier bankability rating and the uncertainty introduced by its recent ownership change make it a higher-risk choice for financed projects. Smaller developers or buyers placing performance above finance-grade bankability may still find Tangra competitive, especially if pricing reflects the brand's transitional status. \---LINKS--- \- https://www.pv-tech.org/industry-updates/thornova-solar-achieves-kiwa-pvel-top-performer-status/ \| Thornova Solar achieves Kiwa PVEL Top Performer status \| article \- https://www.thornova-solar.com/news/corporate-news/305.html \| Thornova Solar maintains B-rating in PVTech Bankability Report \| article \- https://www.solarquotes.com.au/panels/akcome-review.html \| Akcome Solar Panels Review - SolarQuotes \| review \- https://www.solarchoice.net.au/products/panels/akcome-solar-panels-review/ \| Akcome Solar Panels - Independent Review by Solar Choice \| review \- https://comparepv.com/reviews/akcome \| AKCOME Solar Panels Review 2026 - Pros, Cons and Specs \| review Sources: \- \[Thornova Solar achieves Kiwa PVEL Top Performer status - PV Tech\](https://www.pv-tech.org/industry-updates/thornova-solar-achieves-kiwa-pvel-top-performer-status/) \- \[Thornova Solar B-rating in PVTech Bankability Report\](https://www.thornova-solar.com/news/corporate-news/305.html) \- \[Akcome Solar Panels Review - SolarQuotes\](https://www.solarquotes.com.au/panels/akcome-review.html) \- \[Akcome Solar Panels Review - Solar Choice\](https://www.solarchoice.net.au/products/panels/akcome-solar-panels-review/) \- \[AKCOME Solar Panels Review 2026 - ComparePV\](https://comparepv.com/reviews/akcome) Written by claude-sonnet from the figures above. ## Other comparisons - [Tangra vs A.B.
