## Summary

Astronergy is a Chinese solar manufacturer headquartered in Hangzhou, founded in 2006 as a subsidiary of the Chint Group and listed on the Shanghai Stock Exchange since 2016. It holds BloombergNEF Tier 1 bankability recognition and shipped over 30 GW of modules in 2024, placing it among the top six global module suppliers that year. ARTsolar, by contrast, is a 100% South African-owned company founded in Durban in 2010, and it is the only locally owned PV module manufacturer operating in South Africa. Its current assembly capacity stands at approximately 340 MW following a 2025 upgrade carried out in partnership with Chinese manufacturer JA Solar. No BloombergNEF Tier 1 designation for ARTsolar was found in available sources. Astronergy carries the substantially stronger global institutional footprint of the two.

Astronergy's portfolio centers on n-type TOPCon bifacial modules - including the ASTRO N5, N7, and N8 series - spanning a broad wattage range that covers residential rooftops, commercial installations, and utility-scale ground mounts worldwide. The company achieved Top Performer status in PV Evolution Labs reliability testing in 2024 and extended its technology roadmap with a 750 W anti-dust TOPCon module announced in late 2025. ARTsolar serves primarily the South African market, where its locally manufactured content gives it a structural advantage in government-backed procurement programs such as REIPPPP. Through its 2025 agreement with JA Solar, ARTsolar now assembles large-format n-type modules - specifically the JA Solar DeepBlue 4.0 Pro - making its product range competitive on cell technology while remaining anchored to South African project pipelines.

For a buyer outside South Africa, Astronergy is the clear default given its global distribution reach, Tier 1 recognition, proven reliability scores, and fully integrated n-type TOPCon production at scale. ARTsolar becomes the strategically relevant choice for projects inside South Africa that require locally manufactured content to qualify under REIPPPP or similar incentive schemes - in that specific context it is not interchangeable with Astronergy, but a distinct and often mandatory option.
