It is the country's only 100% locally owned PV module producer, operating an assembly facility that was recently upgraded to a 340 MW annual line through a partnership with Chinese manufacturer JA Solar announced in mid-2025. ARTsolar is not listed on the BloombergNEF Tier 1 module rankings, which typically require multi-gigawatt scale and multi-bank project financing evidence, placing it firmly in the regional-manufacturer category. Growatt, founded in 2011 and headquartered in Shenzhen, China, built its name primarily as an inverter and energy-storage supplier rather than a module maker. It claims the position of world's leading residential inverter supplier and distributes across more than 100 countries, giving it a substantially larger global institutional footprint than ARTsolar. ARTsolar serves South Africa's residential, commercial, and utility-scale procurement programmes - most notably the country's risk-mitigation IPP frameworks - and its modules are positioned partly as a locally manufactured alternative that satisfies domestic-content requirements. The JA Solar collaboration adds access to large-format, high-efficiency cell designs to that lineup. Growatt's solar-panel range sits in the budget-to-mid-market tier; independent reviews indicate the panels use PERC cell technology and deliver efficiency figures that are competitive within that price band, though the company's primary competitive strength remains its inverter and hybrid-storage ecosystem rather than its module portfolio. For a buyer outside South Africa who simply needs panels, neither brand sits at the top of the performance hierarchy - Growatt is a reasonable budget choice when bundled with its own inverter, while ARTsolar's value proposition is almost entirely tied to South African local-content rules and supply-chain proximity. A buyer inside South Africa working on projects requiring domestic manufacturing will find ARTsolar the more relevant option; a buyer seeking a globally bankable module should look at established Tier 1 names rather than either of these two. \---LINKS--- \- 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://comparepv.com/reviews/growatt \| Growatt Solar Panels Review 2026 - Pros, Cons and Specs \| review \- https://www.energysage.com/supplier/24759/growatt/ \| Growatt profile and reviews on EnergySage \| review \- https://www.energymatters.com.au/renewable-news/growatt-inverter-review-in-2025-what-to-know/ \| Growatt Inverter Review 2025 - What to Know \| review \- https://techpoint.africa/guide/solar-companies-south-africa/ \| Top 10 trusted solar companies in South Africa 2025 expert guide \| article Sources: \- \[JA Solar, ARTsolar agree to expand PV module manufacturing in South Africa\](https://www.pv-magazine.com/2025/06/17/ja-solar-artsolar-agree-to-expand-pv-module-manufacturing-in-south-africa/) \- \[Growatt Solar Panels Review 2026 - ComparePV\](https://comparepv.com/reviews/growatt) \- \[Growatt profile - EnergySage\](https://www.energysage.com/supplier/24759/growatt/) \- \[Growatt Inverter Review 2025 - Energy Matters\](https://www.energymatters.com.au/renewable-news/growatt-inverter-review-in-2025-what-to-know/) \- \[Top 10 trusted solar companies in South Africa 2025 - TechPoint Africa\](https://techpoint.africa/guide/solar-companies-south-africa/) Written by claude-sonnet from the figures above. ## Other comparisons - [ARTsolar vs A.B.
