ARTsolar vs Thornova Solar - 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
ARTsolar is a South African manufacturer headquartered in Durban, founded in 2010 under the name African Renewable Technologies. It is widely described as South Africa's only locally owned solar panel assembler, with a production facility designed for around 300 MW per year, though utilization has varied with market conditions. A 2025 partnership with JA Solar expanded the plant to a 340 MW assembly operation. ARTsolar has pursued bankable-quality production through successive technology licensing deals - first with Talesun, then LONGi Solar, and now JA Solar - which supply the cell technology and quality oversight that can satisfy project-finance lenders in the South African context, though ARTsolar does not appear independently on the BloombergNEF Tier 1 list as a standalone brand. Thornova Solar, the rebranded commercial identity of Chinese-origin Sunova Solar, manufactures at scale - roughly 2.5 GW of annual capacity in Indonesia - and has held a BloombergNEF Tier 1 designation since August 2023. It carries a B rating in the PV Tech Bankability Report as of Q3 2025 and ranked 14th in Wood Mackenzie's H2 2024 module manufacturing assessment. On independently verified institutional footprint, Thornova has the stronger global standing.
ARTsolar's product catalog centers on monocrystalline TOPCon modules assembled locally in Durban, aimed at South African residential and commercial rooftop buyers as well as the country's Independent Power Producer procurement programme, where local content compliance is a significant purchasing factor. Thornova's lineup extends up to 720 W per module using TOPCon technology - confirmed by a pv-magazine report from March 2024 - and the brand earned a Kiwa PVEL Top Performer award in 2025, signaling reliable durability under stress testing. Thornova's expanding North American distribution, including a partnership with Sunhub, positions it for utility-scale and large commercial projects well beyond its home region.
For most international buyers in 2025, Thornova is the lower-risk default given its independent bankability credentials, broader distribution, and third-party performance validation. ARTsolar is the more logical choice specifically for South African projects where local-content rules, IPP programme compliance, or domestic supply-chain resilience carry procurement weight.
