## Summary

ARTsolar is a South African manufacturer founded in 2011 and headquartered in Pinetown, KwaZulu-Natal, operating as the country's only locally owned solar panel producer. Its production scale has grown through successive technology-transfer partnerships with globally recognised cell makers, most recently agreeing in June 2025 with JA Solar to upgrade its facility to a 340 MW annual production line assembling JA Solar's n-type DeepBlue 4.0 Pro modules. ARTsolar does not carry standalone BloombergNEF Tier 1 status but has reached bankability by leveraging its partners' Tier 1 credentials together with TUV-certified bill of materials and ISO 9001-backed quality management. Exiom Solution S.A. is a Spanish manufacturer with roughly 14 years of sector experience and around 300 employees. It operates two highly automated Chinese factories with a combined stated capacity of approximately 2.7 GW, and in late 2024 opened a 500 MW plant in Langreo, Asturias, built in strategic alliance with utility major Iberdrola - making it one of the first industrial-scale module factories in Europe. Exiom's larger manufacturing base and its Iberdrola tie-up give it a considerably stronger institutional footprint in international markets.

ARTsolar's catalog has historically spanned monocrystalline modules from around 100 W to 500 W, primarily targeting residential rooftops and small commercial installations across sub-Saharan Africa. The 2025 JA Solar partnership shifts its flagship output toward high-efficiency n-type technology, broadening its appeal to utility-scale developers who must also satisfy South African local-content procurement thresholds. Exiom covers a wider watt-class range - roughly 270 W to around 605 W - and its portfolio encompasses PERC, TOPCon, HJT, and bifacial configurations. Its higher-wattage, multi-technology lineup makes it a natural fit for utility-scale ground mounts and larger commercial rooftops across the EU, where European-manufactured provenance is increasingly valued under energy-security policy.

For buyers outside sub-Saharan Africa, Exiom's scale, European manufacturing credentials, and broader technology portfolio make it the more versatile default choice heading into 2025-2026. ARTsolar is, however, the compelling and often obligatory option for projects needing to satisfy South African REIPPPP local-content rules, and its JA Solar-backed line now produces genuinely competitive n-type modules for that context. The two brands largely serve distinct geographies and procurement frameworks, so a direct substitution between them is unlikely in practice.
