## Summary

Renewsys is an Indian manufacturer headquartered in Mumbai, Maharashtra, founded as an integrated solar components business that expanded into module production. The company is recognized as a Tier 1 manufacturer, and in early 2026 it inaugurated a new 3 GW automated module plant in Khopoli, bringing its total reported module capacity to roughly 5.6 GW. Beyond modules, Renewsys manufactures cells, encapsulants, and backsheets in-house, with encapsulant lines recently scaled to a cumulative 30 GW of capacity. ARTsolar, by contrast, is a South African manufacturer based in Durban, founded in 2010 and operating as the country's only 100% locally owned solar PV module producer. Its assembly facility, upgraded through a technology partnership with JA Solar, runs at a reported 340 MW of annual capacity - a fraction of Renewsys's scale. ARTsolar does not appear on mainstream global Tier 1 or BloombergNEF bankable manufacturer lists, whereas Renewsys carries recognized Tier 1 standing, giving it a clearly stronger institutional footprint for project finance purposes.

On the product side, Renewsys has moved firmly toward N-type technology, offering TOPCon bifacial and monofacial modules in the 550-640 Wp range alongside legacy mono PERC lines, positioning it for utility-scale ground-mount, large commercial rooftop, and export markets. ARTsolar manufactures high-efficiency large-format modules aligned with JA Solar's current designs and also carries product lines under the Honeywell brand following a Clean Energy Associates audit - targeting primarily South African residential, commercial, and public-sector projects where local-content requirements apply. The company backs its modules with a 30-year linear power output guarantee, which is competitive, but the value of that guarantee depends heavily on the manufacturer's long-term financial continuity, which has faced uncertainty after ARTsolar laid off over 300 workers in 2025 amid project delays.

For a buyer outside South Africa in 2025, Renewsys is the more straightforward default: it carries Tier 1 bankability, multi-GW scale, and a diversifying technology portfolio suitable for project finance. ARTsolar's strongest case is for South African buyers who need or want to meet local-content procurement rules - its partnership with JA Solar brings credible module quality, but its operational difficulties make due diligence on long-term warranty coverage especially important before committing.
