## Summary

Renesola is a Chinese solar manufacturer founded in 2005 and listed on the New York Stock Exchange since 2008, with production facilities spanning China, Turkey, India, Taiwan, and South Africa. It has maintained BloombergNEF Tier 1 bankability status consistently, including through all reported quarters of 2025, and has accumulated over 25 GW in cumulative global shipments. ARTsolar, founded in 2010 and headquartered in KwaZulu-Natal, South Africa, is the only 100% locally owned photovoltaic manufacturer in that country, operating an assembly plant that has been expanded to approximately 340 MW annual capacity following a 2025 technology partnership with JA Solar. It does not appear on the BNEF Tier 1 list and operates at a scale an order of magnitude smaller than Renesola, giving Renesola the stronger institutional and financial footprint by a wide margin.

Renesola offers a broad catalog spanning residential rooftop, commercial, and utility-scale ground-mount segments, with a product range extending from compact lightweight modules up to high-wattage double-glass formats. Its confirmed cell technologies include N-type TOPCon and HJT variants alongside conventional PERC-generation lines. ARTsolar's product offering has historically centered on panels suited for South African utility-scale IPP programmes - particularly government-backed REIPPPP tenders - while also supplying residential and commercial installers domestically. Through its JA Solar partnership, ARTsolar began producing DeepBlue 4.0 Pro N-type modules locally in 2025, bringing higher-efficiency N-type technology to a market where local content requirements are a key procurement criterion.

For a buyer outside South Africa, Renesola is the default choice given its global distribution network, verified BNEF Tier 1 bankability, and broader technology portfolio. ARTsolar is a compelling option specifically for South African projects where local-content compliance is mandatory or commercially advantageous, but its ongoing legal disputes and 2025 workforce reductions introduce near-term supply-chain risk worth monitoring.
