Written summary
ARTsolar is a South African manufacturer founded in 2011 and headquartered in Pinetown, KwaZulu-Natal. It is the only 100% locally owned solar panel assembler in South Africa, with an annual production capacity of around 300 MW. The company does not appear on BloombergNEF's formal Tier 1 module list as an independent entry; its bankability instead rests on strategic tie-ups with globally ranked Tier 1 makers - most recently JA Solar, with whom it agreed in mid-2025 to co-produce 340 MW of n-type modules annually, and previously LONGi. Hanersun is a Chinese manufacturer headquartered in Nanjing that entered the BloombergNEF Tier 1 list in Q2 2023 on the strength of its 600 W-plus high-efficiency products. It has a substantially larger global manufacturing footprint and active international distribution, including a presence at Intersolar Europe 2025. On institutional recognition and global scale, Hanersun holds the stronger position.
For products, ARTsolar assembles modules - currently including n-type TOPCon panels such as the JA Solar DeepBlue 4.0 Pro series - primarily aimed at utility-scale and large commercial ground-mount projects within South Africa, where local-content procurement rules give domestically assembled modules a structural advantage. Hanersun's portfolio spans a wide power range (roughly 420 W to 750 W-plus) and covers TOPCon, HJT, and its proprietary ABC back-contact technology, reaching efficiencies up to around 23-24 percent. Its lineup serves residential rooftops, C&I installations, and utility-scale projects across multiple geographies.
For a buyer operating outside South Africa with no local-content obligation, Hanersun is the more straightforward choice: it offers verified Tier 1 status, a broader technology menu, and an established international supply chain. ARTsolar's proposition is compelling specifically within the South African market, where its government-procurement eligibility and local manufacturing story add real value that Hanersun cannot replicate.
