## Summary

ARTsolar is a South African manufacturer founded in 2010 and headquartered in Durban, making it the only 100% locally owned solar panel producer in the country. Its facility uses Swiss and German equipment and, following a 2025 agreement with JA Solar, operates a 340 MW assembly line producing large-format n-type modules. ARTsolar does not appear on BloombergNEF's Tier 1 bankability list, which limits its eligibility for certain project-finance structures outside South Africa. LONGi Solar, by contrast, was founded in 2000 in Xi'an, China, and is one of the world's largest module producers, with annual production capacity exceeding 110 GW and BloombergNEF Tier 1 recognition for both modules and storage. In terms of institutional footprint and global bankability, LONGi is in an entirely different league.

On the product side, ARTsolar's current lineup centers on modules assembled under JA Solar's DeepBlue 4.0 Pro platform, targeting domestic utility and commercial projects that must meet South Africa's local-content procurement rules. LONGi's Hi-MO series covers a much wider range of applications - from premium residential rooftops to large utility-scale ground mounts. Its flagship lines use proprietary HPBC 2.0 back-contact cell technology, with the Hi-MO X10 delivering 670 W output at 24.8% module efficiency, and the newer HIBC platform achieving a certified cell efficiency of 27.81%, currently a world record.

For a buyer outside South Africa, LONGi is the clear default choice in 2025: its global supply chain, Tier 1 bankability, and leading cell technology make it suitable for virtually any project type. ARTsolar's value proposition is specific and legitimate - it exists to serve South African projects where local-content compliance, job creation, and rand-denominated supply chains matter. Buyers in that context may actually prefer ARTsolar, but the two brands are not interchangeable on the global stage.
