ARTsolar vs Sunova - solar panel manufacturer comparison

Sunova, marketed in some regions under the Thornova Solar brand, is a Chinese manufacturer founded in 2016 with cell and module production facilities in Sichuan province and Indonesia. It has held Bloomberg New Energy Finance (BNEF) Tier 1 status since August 2023 and received a "B" bankability rating in the PV Tech Module Bankability Report as recently as 2025, reflecting assessed low financial risk. The company reports a module manufacturing capacity of approximately 6.5 GW per year, with cumulative global shipments reaching 7.1 GW by the end of 2024. ARTsolar, founded in 2010 and headquartered in Durban, South Africa, is positioned as the country's only 100% locally owned solar panel manufacturer, operating a facility capable of up to 250 MW of annual module output. ARTsolar does not appear on the BNEF Tier 1 list. Sunova holds a substantially stronger institutional footprint of the two.

Sunova's product range spans n-type TOPCon modules under the Tangra series and PERC-based modules under the Zosma series, with large-format G12 bifacial variants targeting utility-scale ground mounts alongside standard residential formats. The company has also signaled plans to add North American manufacturing capacity. ARTsolar serves the South African residential and commercial rooftop market, offering modules certified to both local and international standards and backed by a 30-year linear power output guarantee. Its production equipment supports PERC, bifacial, N-type, and HJT cell formats, and the company holds status as an authorized manufacturing facility for Honeywell-branded panels, with a supply partnership involving JA Solar intended to support South Africa's government procurement programs.

For buyers outside South Africa, Sunova is the more practical default given its Tier 1 bankability, multi-GW scale, and broad global distribution. ARTsolar is a meaningful option specifically within South Africa, where local-content requirements under programs such as the REIPPP provide a direct incentive to source domestically, and where its on-the-ground warranty support adds practical value. Prospective buyers should note that ARTsolar faced production and financial headwinds in 2024-2025, including significant workforce reductions, which are worth monitoring from a supply-continuity perspective.
