DAH vs ARTsolar - solar panel manufacturer comparison
Both brands are closely matched on catalog size, efficiency and bifacial share - the choice comes down to local availability, price and specific model features.
Both catalogues are read from the manufacturers' own datasheets. A brand is not scored against the market here, only against the other brand on this page.

Catalogue against catalogue
An average over a catalogue describes the range a manufacturer publishes, not the module you would buy. A brand with two flagship panels and eighty older ones averages worse than one that has retired its back catalogue.
What each of them builds
Written summary
ARTsolar, founded in 2010 and headquartered in Durban, is South Africa's only locally owned solar panel manufacturer. Operating at roughly 325-340 MW of annual assembly capacity through partnerships with larger Chinese cell suppliers, it serves primarily the South African residential and commercial market. DAH Solar, established in 2009 in Hefei, China, works at a substantially larger scale, targeting up to 10 GW of TOPCon module output, and distributes to more than 120 countries. DAH Solar has been listed on BloombergNEF's Tier 1 PV Module roster continuously through 2025, with confirmed appearances in Q1, Q3, and Q4, a bankability credential that matters to project lenders and international developers. ARTsolar does not appear on published BNEF Tier 1 lists, reflecting both its regional footprint and the qualifying barriers smaller manufacturers face. By any measure of global institutional standing, DAH Solar is the larger and more broadly recognized entity.
ARTsolar offers a broad wattage range for local buyers, including monocrystalline PERC and N-type TOPCon panels reaching around 550-600 W, targeting residential rooftops and small-to-medium commercial systems with a value proposition built on local manufacturing, local certification, and in-country warranty support. DAH Solar is best known for its patented Full-Screen module series, a frameless anti-dust design built on TOPCon cell technology, with cumulative shipments of that product line reaching approximately 4.5 GW. The company's newer V6 series breaks through the 24% efficiency threshold, and its portfolio spans residential, commercial, and utility-scale applications across multiple continents. Independent reviewers note that DAH Solar's specifications are competitive within the Chinese Tier 1 peer group, though not always class-leading.
For buyers in South Africa who value locally assembled panels and domestic warranty backing, ARTsolar is a credible and locally relevant choice. For projects outside South Africa, or anywhere international lenders or bankability requirements apply, DAH Solar is the more practical option given its Tier 1 status, wider distribution network, and well-documented TOPCon technology. The two brands are not meaningfully interchangeable in most markets given their very different geographic footprints, but each is well positioned for its primary audience.
