## Summary

ARTsolar was established in 2010 in Durban, South Africa, and is the country's only 100%-locally-owned solar module manufacturer. The company operates a production facility with a stated annual capacity of up to 300 MW and has partnered with global suppliers including Talesun Solar and LONGi to source Tier 1-grade cells, marketing its output as meeting Tier 1 quality standards. ARTsolar does not appear on the BloombergNEF independent Tier 1 module manufacturer rankings. The company has faced severe operational headwinds in 2025, including a high-court dispute over local-content requirements in South Africa's government-backed renewable energy program and the loss of over 300 employees following project shortfalls. Solar-Fabrik is a German manufacturer with more than 25 years of industry history that recently recommitted to domestic production after a period of China-based manufacturing. In May 2025 the company broke ground on a 300 MW "Factory One" facility in Hosbach, Bavaria, focusing on N-type TOPCon and heterojunction cell technologies. Solar-Fabrik also does not appear on the BloombergNEF Tier 1 list, placing both brands outside the institutional mainstream dominated by manufacturers such as JinkoSolar or LONGi. In European project-finance contexts, Solar-Fabrik carries the stronger brand equity due to its German manufacturing heritage.

ARTsolar's catalog is oriented toward utility-scale ground-mount procurement within South Africa's domestic renewable energy program, with monocrystalline module lines distributed locally. Solar-Fabrik targets a broader product mix: its new TOPCon-based modules rated at around 450 W are aimed at residential and commercial rooftop installers across Europe, while a separate 315 W line addresses the growing balcony power-system segment. The "Made in Germany" positioning supports premium pricing and is a deliberate differentiator against lower-cost Asian imports, with the company investing approximately EUR 6 million in the new facility without government subsidies.

For buyers outside South Africa, Solar-Fabrik is the more relevant option, supported by European quality certifications and a technology roadmap aligned with the industry's shift to N-type cells. ARTsolar is the more logical default for South African projects where local-content compliance and regional support infrastructure matter - but prospective buyers should assess the company's operational stability carefully given the 2025 workforce reductions and ongoing litigation. The two brands are not meaningfully interchangeable; they serve distinct geographies and project types.
