ARTsolar vs Tesla - 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
Tesla is a United States-based company, operating its solar business through the Tesla Energy division headquartered in Austin, Texas. Originally known as an electric vehicle maker, Tesla entered the solar market through its 2016 acquisition of SolarCity and has since positioned itself primarily as a vertically integrated energy company rather than a standalone panel manufacturer. Tesla does not appear on the BloombergNEF Tier 1 solar module list, reflecting that its identity in solar is more that of a residential installer and system integrator than a large-scale module producer. ARTsolar, by contrast, is a dedicated panel manufacturer founded in 2011 and headquartered in Pinetown, South Africa, making it the country's only locally owned solar module producer. In March 2025, ARTsolar announced a manufacturing partnership with JA Solar - a globally Tier 1-rated supplier - that lifted the facility's annual production capacity to approximately 340 MW, giving the brand a credible institutional anchor in the African market. On institutional footprint globally, Tesla's brand recognition is far broader, though ARTsolar holds a structurally stronger position as an independent manufacturing entity within its home region.
Tesla's product line centers on the T400H, a 400-watt all-black monocrystalline module with a reported efficiency of around 20.4%, designed almost exclusively for premium residential rooftops in the United States. Its appeal rests heavily on ecosystem integration - pairing seamlessly with the Powerwall home battery and Tesla EV chargers - rather than on any particular cell-technology differentiator, since available specifications do not confirm a PERC or TOPCon designation for the T400H. ARTsolar offers a broader catalog spanning domestic and commercial applications, including monocrystalline modules such as the ART370-72M, and holds TUV (IEC) and SABS certifications. The company has demonstrated utility-scale supply capability, having delivered panels for a 75 MW project implemented by Juwi Renewable Energies, and the JA Solar partnership is expected to orient future output toward South Africa's government-backed renewable procurement programs.
For a typical buyer in 2025, the two brands serve fundamentally different markets and are not interchangeable. A US homeowner who values tight ecosystem integration with a Powerwall and a Tesla vehicle, and who is comfortable with the brand's historically inconsistent customer service, may find Tesla a reasonable choice. A buyer in South Africa or sub-Saharan Africa - whether residential or commercial - will find ARTsolar more accessible, locally supported, and increasingly well-capitalized through the JA Solar partnership. Neither brand is the obvious global default: Tesla lacks Tier 1 module-maker status and geographic breadth, while ARTsolar remains a regional player still building its international profile.
