The company has been a vocal advocate for domestic localisation requirements in South African renewable-energy tenders. However, ARTsolar's "local manufacturer" positioning has been severely undermined by an ongoing legal dispute: court filings reported by GroundUp and Oxpeckers in 2025 revealed shipping records showing the company imported roughly 99% of its panels from China between 2019 and 2023, with allegations that it misrepresented its production operations to funders, regulators, and customers. ARTsolar does not appear on the BloombergNEF Tier 1 bankability list. MY Solar Technology Co., Ltd. (MYPVTECH), by contrast, is a Chinese manufacturer founded in 2010 and listed on ENF Solar, reporting an annual module production capacity of around 3 GW alongside inverter and energy storage lines. MY Solar also does not appear on the BloombergNEF Tier 1 list, but its scale and OEM-ODM activity give it a broader institutional footprint than ARTsolar currently has. MY Solar serves residential, commercial, and small utility markets across Europe, the Americas, Asia, and Africa through both branded and OEM channels, which means its modules turn up under various trade names. No independent review source confirmed the specific cell technology mix for MY Solar's current catalog, so a technology designation cannot be responsibly stated here. ARTsolar's product line - to the extent it reflects genuine local assembly rather than relabelled Chinese imports - has historically targeted the South African rooftop and commercial backup market, where local certification and after-sales support proximity matter to buyers. For a typical buyer in 2025, neither brand represents a straightforward first choice. MY Solar carries the reputational risks common to lesser-known Chinese mid-tier makers - limited independent reviews, uncertain long-term warranty enforcement outside its home market - but it at least has verifiable production scale. ARTsolar carries a more immediate and specific credibility problem: the documented gap between its "proudly local" marketing and its actual supply chain makes due diligence essential before specifying it on any project, particularly one with local-content obligations. Buyers in South Africa who need a locally sourced panel for compliance purposes should verify ARTsolar's current manufacturing status directly with the company and the IDC before committing. \---LINKS--- \- https://groundup.org.za/article/local-manufacturer-actually-imports-99-its-product-court-told/ \| ARTsolar imports 99% of panels, court told - GroundUp \| article \- https://oxpeckers.org/2025/11/solar-court-case/ \| Court case tackles not-so-proudly-South African solar power - Oxpeckers \| article \- https://www.pv-magazine.com/2026/05/13/artsolar-challenges-local-content-compliance-in-south-african-solar-tenders/ \| ARTsolar challenges local content compliance in SA tenders - PV Magazine \| article \- https://www.enfsolar.com/my-solar \| MY Solar Technology Co.
