The company has confirmed BloombergNEF Tier 1 status, most recently reaffirmed for Q1 2025 and Q1 2026, and operates approximately 2.5 GW of annual module production capacity. It holds certifications from TUV Rheinland, CE, US ETL, Brazil's INMETRO, and ISO 9001/14001/45001, giving it a broad compliance footprint for international project finance. ARTsolar, by contrast, is a South African manufacturer founded in 2010 and based in Durban, KwaZulu-Natal. It describes itself as South Africa's only locally owned solar panel maker and has an annual assembly capacity that has grown toward 340 MW following a 2025 facility upgrade in partnership with JA Solar. ARTsolar does not appear on BNEF Tier 1 lists in its own right, though its new JA Solar tie-up brings globally bankable module designs into the facility. On institutional footprint and scale, Horay Solar holds a clear advantage. In terms of products, Horay Solar covers a wide range of applications - from commercial rooftop to utility-scale ground mounts - using mono-crystalline PERC, TOPCon, HJT, and back-contact (BC) cell technologies. Its bifacial modules in the 440-665 W range are targeted at developers seeking financeable, high-output solutions for international markets. ARTsolar has historically focused on PERC modules in the 545-550 Wp range for the South African utility and commercial market, particularly supplying into government programs such as REIPPP and RMIPPP. Its updated 340 MW line now assembles large-format JA Solar-designed modules incorporating TOPCon technology, broadening its product offering for high-efficiency projects. For a buyer outside southern Africa, Horay Solar is the more straightforward default - it is BNEF Tier 1 certified, operates at far greater scale, and its products are distributed across multiple continents with recognized third-party certifications. ARTsolar is a compelling choice specifically within South Africa, where local content requirements, government program eligibility, and proximity to the supply chain make its domestically assembled panels a meaningful differentiator. The two brands are not interchangeable: they serve largely different geographies and procurement contexts. \---LINKS--- \- https://www.horaysolar.com/News/230.html \| Horay Solar Recognised as BloombergNEF Tier 1 Manufacturer \| article \- https://www.pv-magazine.com/2025/06/17/ja-solar-artsolar-agree-to-expand-pv-module-manufacturing-in-south-africa/ \| JA Solar and ARTsolar agree to expand PV module manufacturing in South Africa \| article \- https://www.pv-magazine.com/2022/11/07/talesun-artsolar-open-325-mw-module-factory-in-south-africa/ \| Talesun and ARTsolar open 325 MW module factory in South Africa \| article \- https://www.enfsolar.com/horay-solar \| Horay Solar Co., Ltd - ENF Solar manufacturer profile \| article \- https://www.enfsolar.com/artsolar \| ARTsolar (Pty) Ltd - ENF Solar manufacturer profile \| article Sources: \- \[Horay Solar BNEF Tier 1 announcement\](https://www.horaysolar.com/News/230.html) \- \[JA Solar and ARTsolar PV manufacturing expansion - pv magazine\](https://www.pv-magazine.com/2025/06/17/ja-solar-artsolar-agree-to-expand-pv-module-manufacturing-in-south-africa/) \- \[Talesun and ARTsolar 325 MW factory - pv magazine\](https://www.pv-magazine.com/2022/11/07/talesun-artsolar-open-325-mw-module-factory-in-south-africa/) \- \[Horay Solar - ENF Solar profile\](https://www.enfsolar.com/horay-solar) \- \[ARTsolar - ENF Solar profile\](https://www.enfsolar.com/artsolar) Written by claude-sonnet from the figures above. ## Other comparisons - [ARTsolar vs A.B.
