## Summary

ARTsolar is a South African manufacturer founded in 2010 and headquartered in Durban, operating as the country's only 100% locally owned solar panel producer. It is a niche, domestically focused player with an assembly capacity of roughly 340 MW per year, a level enabled by a strategic partnership with Chinese Tier 1 manufacturer JA Solar announced in June 2025. ARTsolar does not appear on BloombergNEF's Tier 1 bankability list. Trina Solar, founded in December 1997 in Changzhou, China, operates at a radically different scale: annual production capacity of approximately 100 GW, cumulative global shipments exceeding 225 GW, and a consistent presence on the BloombergNEF Tier 1 list - which it has topped on eight occasions. Trina Solar maintains commercial operations in over 170 countries, and on institutional footprint it is the significantly stronger entity.

ARTsolar's product range centers on large-format TOPCon-based modules developed in collaboration with JA Solar, serving residential rooftop, commercial, and independent power producer segments within South Africa. The company's market position is tightly linked to government procurement rules that reward locally assembled content - though court proceedings in 2025 raised substantive questions about the actual proportion of in-country value add, an issue the JA Solar partnership is intended to address at the upgraded Durban facility. Trina Solar covers the full spectrum of applications through its Vertex product families. The Vertex S+ G3, a dual-glass N-type TOPCon module, entered mass production in Q2 2025 targeting residential and commercial rooftop installations, while the Vertex N i-TOPCon Ultra - bifacial modules delivering outputs exceeding 740 W - serves utility-scale ground-mount projects globally and was in international delivery by late 2025.

For buyers outside South Africa, Trina Solar is the clear default choice: its Tier 1 status, global logistics network, and product depth from residential to utility scale deliver the bankability that project lenders and EPC contractors require. ARTsolar serves a genuinely distinct purpose, one driven by South African localisation policy rather than open-market competitiveness. In any procurement context that does not involve that specific regulatory incentive, the two brands are not interchangeable.
