ARTsolar, founded in 2010 and headquartered in South Africa, markets itself as the country's only locally owned solar panel manufacturer, with a stated annual capacity of approximately 250 MW; court proceedings active in 2025 and 2026, however, surfaced claims that up to 99% of its panels are imported from China, a controversy that materially clouds its institutional credibility. Neither brand appears on the BloombergNEF Tier 1 bankable list. On manufacturing depth and international footprint, Gokin is overwhelmingly the larger player. The two lineups differ sharply in breadth, technology, and buyer fit. Gokin fields a 44-panel portfolio in which Back Contact (BC) architecture accounts for roughly 80% of the range; average output sits at 517 Wp, peak output reaches 780 Wp, average efficiency is 23.6%, and the top panel hits 24.5%. Its average temperature coefficient of -0.26%/C is notably low, making it well suited to hot climates. Around 11% of its panels are bifacial. ARTsolar's portfolio consists of a single TOPCon N-type module rated at 600 Wp with a 23.21% efficiency, a -0.31%/C temperature coefficient, and no bifacial option. Gokin's range serves residential rooftops, C&I, and utility-scale projects alike; ARTsolar's single SKU targets commercial or large residential installations where South African local-procurement preferences may apply. For most buyers outside South Africa in 2025, Gokin is the more defensible choice - broader product selection, marginally superior efficiency, a better temperature coefficient, and far greater manufacturing depth behind its warranties. ARTsolar's primary appeal is geographic and regulatory: its 600 Wp TOPCon panel may satisfy local-content thresholds in South African tenders, but buyers should weigh the unresolved legal questions about its actual manufacturing origin before relying on that distinction. \---LINKS--- \- https://www.pv-magazine.com/2025/12/15/gokin-solar-launches-new-back-contact-solar-module-series/ \| Gokin Solar launches new back-contact solar module series \| article \- https://solarquarter.com/2026/02/09/gokin-solar-enters-solarbes-2025-global-pv-module-shipment-rankings/ \| Gokin Solar enters Solarbe 2025 global PV module shipment rankings \| article \- https://groundup.org.za/article/local-manufacturer-actually-imports-99-its-product-court-told/ \| ARTsolar court claim - local manufacturer imports 99% of product \| article \- https://oxpeckers.org/2025/11/solar-court-case/ \| South Africa solar court case tackles localisation claims \| article Sources: \- \[Gokin Solar launches new back-contact solar module series - PV Magazine\](https://www.pv-magazine.com/2025/12/15/gokin-solar-launches-new-back-contact-solar-module-series/) \- \[Gokin Solar enters Solarbe 2025 global PV module shipment rankings - SolarQuarter\](https://solarquarter.com/2026/02/09/gokin-solar-enters-solarbes-2025-global-pv-module-shipment-rankings/) \- \[ARTsolar - local manufacturer actually imports 99% of its product, court told - GroundUp\](https://groundup.org.za/article/local-manufacturer-actually-imports-99-its-product-court-told/) \- \[South Africa solar court case tackles not-so-proudly-South African solar power - Oxpeckers\](https://oxpeckers.org/2025/11/solar-court-case/) Written by claude-sonnet from the figures above. ## Other comparisons - [ARTsolar vs A.B.
