## Summary

ARTsolar is a South African manufacturer founded in 2011 and headquartered in Pinetown, KwaZulu-Natal, positioning itself as South Africa's only locally owned solar panel producer. The company has faced significant legal controversy: court documents revealed that between 2019 and 2023 approximately 99% of panels sold under the ARTsolar name were imported from China rather than assembled domestically. ARTsolar does not appear on BloombergNEF's Tier 1 PV module list, and its stated production capacity has been reported at around 300 MW per year, though actual output ran well below that figure; the company terminated more than 300 workers in mid-2025 as anticipated project pipelines failed to materialize. DAH Solar, formally Anhui Daheng Energy Technology Co., Ltd., was established in 2009 in Hefei, China, and has secured consistent placement on BloombergNEF's Tier 1 PV module list across Q1, Q3, and Q4 2025. The company operates an integrated manufacturing chain with a reported module capacity of up to 10 GW per year and distributes products to more than 120 countries, with Europe and Latin America as its primary export regions. On institutional footprint and bankable credibility, DAH Solar holds a clear advantage.

ARTsolar's product lineup is aimed squarely at residential rooftop and small commercial installations in the South African domestic market. The company has cultivated partnerships with Chinese Tier 1 suppliers - including JA Solar and previously LONGi - to source and assemble monocrystalline modules that can satisfy local-content requirements under South African government procurement frameworks. This localization benefit carries little weight for buyers outside the region. DAH Solar, by contrast, offers a broad portfolio spanning residential, commercial and industrial, and utility-scale ground-mount applications. Its flagship DHN series leverages TOPCon cell technology across a power range stretching from roughly 420 Wp to beyond 700 Wp. The company's best-known innovation is its patented Full-Screen frameless bifacial module, which reduces soiling-related losses and raises energy yield; cumulative Full-Screen shipments had reached around 4.5 GW by 2024, with the V6 series adding double-glass variants suited to demanding climates.

For a buyer outside South Africa, DAH Solar is the more practical default. It carries verified Tier 1 bankability, serves an established distribution network across Europe and beyond, and fields a well-documented TOPCon lineup covering virtually every segment. ARTsolar's competitive case is narrowly regional - it is most relevant where South African local-content rules apply and a domestic support network matters. International buyers evaluating the two brands for a European or global project will find them far from interchangeable: DAH Solar is financed, distributed, and certified for those markets; ARTsolar is not.
