ARTsolar vs Tangra - solar panel manufacturer comparison
Both brands are closely matched on catalog size, efficiency and bifacial share - the choice comes down to local availability, price and specific model features.
Both catalogues are read from the manufacturers' own datasheets. A brand is not scored against the market here, only against the other brand on this page.

An average over a catalogue describes the range a manufacturer publishes, not the module you would buy. A brand with two flagship panels and eighty older ones averages worse than one that has retired its back catalogue.
What each of them builds
Written summary
Tangra is the flagship module line of Thornova Solar, a manufacturer that began operations around 2022 with production facilities in China. The brand achieved Bloomberg NEF Tier 1 status in Q3 2023 and holds a B-rating in the PV Tech ModuleTech Bankability Report, meeting the minimum financial-credibility threshold recognized by most project lenders. ARTsolar was founded in 2010 in Durban, South Africa, marketing itself as the country's only locally owned solar panel manufacturer - its name standing for African Renewable Technologies. ARTsolar has not appeared on BNEF's Tier 1 list and carries substantially less international institutional recognition; on that measure, Thornova holds a meaningfully stronger global footprint.
Thornova's Tangra line centers on high-wattage N-type bifacial dual-glass modules, with the Tangra M PRO series rated in the 575-595 W range. In 2025, Kiwa PVEL recognized these modules as Top Performers across all seven reliability test categories - including thermal cycling, damp heat, PID, and hail resistance - making them well suited for utility-scale and commercial ground-mount projects where third-party durability validation is expected. ARTsolar offers monocrystalline modules, including panels incorporating TOPCon cells sourced through partnerships with established manufacturers such as BYD and JA Solar, and targets primarily the South African residential and commercial rooftop segment. The company received IDC funding of R96.8 million in 2022 to expand local production, but a 2024 court case brought attention to allegations that the large majority of modules sold under the ARTsolar brand were imported from China rather than assembled domestically, a dispute that remained unresolved as of late 2025.
For buyers outside South Africa, Thornova's Tangra modules are the more straightforward option: recognized third-party quality certification, BNEF Tier 1 status, and a growing international project record support financing. ARTsolar's appeal is largely regional - its local-content positioning holds regulatory value in South Africa's REIPPP programme - but ongoing legal uncertainty about the extent of its domestic manufacturing adds risk for developers pursuing strict localisation compliance.
