## Summary

ARTsolar is a South African manufacturer founded in 2011 and headquartered in Pinetown, near Durban. It is 100% locally owned and is backed by financing from the Industrial Development Corporation. The facility is rated for up to 300 MW of annual output and holds Tier 1 module accreditation, making it the only South African-owned plant with that rating. In June 2025, ARTsolar formalized a partnership with JA Solar to upgrade its production line to 340 MW per year for high-efficiency, large-format modules, directly supporting South Africa's utility procurement programmes. Weran Solar, by contrast, was founded in 2015 and is headquartered in Shanghai, China. It operates primarily as an authorized LONGi distributor rather than an independent module manufacturer at scale, and no independently verified Tier 1 or BloombergNEF bankability status for Weran Solar itself has surfaced in available sources. On institutional footprint, ARTsolar carries the stronger standing.

ARTsolar's product focus is on utility-scale and large commercial ground-mount projects in Southern Africa. Its updated production line assembles TOPCon modules - confirmed through the JA Solar collaboration - with efficiency ratings around 23.2%, and panels carry TUV IEC and SABS certification. Weran Solar positions itself across a wider product mix including PERC, HPBC (LONGi back-contact technology), and N-TOPCon modules, targeting residential, commercial, agro-solar, and industrial buyers. It established a Nigerian warehouse and distribution hub in the Lekki Free Trade Zone in 2024, making it an increasingly visible supplier across West Africa.

For a buyer in South Africa who requires locally assembled content under government procurement rules, ARTsolar is the clear choice. For buyers elsewhere in sub-Saharan Africa seeking cost-effective LONGi-backed modules through a regional distributor, Weran Solar offers a practical route. The two brands serve largely different supply chains, so direct substitution is uncommon in practice.
