The company claims Tier 1 status on its own materials, though it does not appear on widely cited independent bankability lists such as those published by BloombergNEF, and its annual production scale has not been confirmed by third-party sources. ARTsolar was established in 2010 in Durban, South Africa, and is the only 100% locally owned solar panel manufacturer in the country. It assembles modules using imported cells, glass, and frames, and holds TUV-IEC and SABS certifications. A manufacturing partnership with JA Solar announced in March 2025 upgraded ARTsolar's facility to 340 MW per year, with a second line targeting a combined capacity of roughly 1 GW. ARTsolar's long track record supplying South Africa's government-backed REIPPPP procurement rounds gives it the stronger institutional footprint of the two. Fellow Energy's catalog focuses on monocrystalline bifacial panels aimed at residential rooftops and distributed generation - its website highlights panels in the 550W class - but independent technical reviews from established outlets are sparse, and cell technology specifics have not been confirmed by third-party sources. ARTsolar is oriented primarily toward utility-scale and large commercial ground-mount projects within the South African IPP market. Through its JA Solar partnership, ARTsolar became the first manufacturer in Africa to assemble n-type TOPCon modules locally - the JA Solar DeepBlue 4.0 Pro series - a meaningful technology step-up that strengthens its competitive position for developers where local content rules apply. For buyers outside South Africa, neither brand figures prominently in global review coverage, and established Tier 1 names may offer more straightforward warranty enforcement and bankability. Within South Africa, ARTsolar is the more defensible choice for project developers subject to local content requirements, with a JA Solar-backed TOPCon lineup and a certifiable domestic production story. Fellow Energy may suit Turkish or regional Middle Eastern buyers seeking a domestically manufactured option, but limited independent review coverage warrants additional due diligence before large-scale commitments. \---LINKS--- \- https://www.pv-magazine.com/2025/06/17/ja-solar-artsolar-agree-to-expand-pv-module-manufacturing-in-south-africa/ \| JA Solar and ARTsolar agree to expand PV module manufacturing in South Africa \| article \- https://www.engineeringnews.co.za/article/artsolar-and-ja-solar-driving-south-africas-renewable-energy-revolution-2025-06-12 \| ARTsolar and JA Solar - driving South Africa's renewable energy revolution \| article \- https://comparepv.com/reviews/artsolar \| ARTsolar Solar Panels Review 2026 - ComparePV \| review \- https://comparepv.com/reviews/fellow-energy \| Fellow Energy Solar Panels Review 2026 - ComparePV \| review \- https://oxpeckers.org/2025/11/solar-court-case/ \| Court case tackles not-so-proudly-South African solar power \| article Written by claude-sonnet from the figures above. ## Other comparisons - [ARTsolar vs A.B.
