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.

Silfab Solar is a North American manufacturer with roots in Toronto, Canada, where it was founded in 2010 and has maintained its corporate headquarters. It operates module production in Bellingham, Washington and is adding fully integrated cell-and-module manufacturing in Fort Mill, South Carolina - a facility backed by $110 million in U.S. 45X Advanced Manufacturing Tax Credits secured in May 2025. Silfab holds Tier 1 bankability status and is recognized by major financiers as a reliable domestic supplier, a distinction that gives it a strong position among installers seeking IRA-compliant, U.S.-made hardware. ARTsolar, also founded in 2010, is headquartered in Durban, South Africa, and is the country's only 100% locally owned solar module manufacturer. It recently upgraded its Durban facility to a 340 MW assembly line through a partnership with JA Solar announced in June 2025. ARTsolar does not appear on major BloombergNEF Tier 1 lists, though its products carry international certifications and it holds an important position as a local-content supplier within South Africa's IPP procurement programs. On institutional footprint, Silfab has the broader international standing.

On the product side, Silfab targets premium residential rooftops and light commercial installations in North America, with its current lineup built around n-type TOPCon technology and a newer back-contact module line it is scaling at its Bellingham plant following the May 2025 acquisition of EnPV's patent portfolio. Warranties run to 25 years on the product and 30 years on linear performance. ARTsolar focuses primarily on utility-scale and commercial ground-mount projects within Sub-Saharan Africa, assembling large-format modules using JA Solar cells under the new partnership arrangement. It also offers a 30-year linear output guarantee and serves residential buyers through its own e-commerce channel, though utility and commercial work remains its core market.

For a buyer in North America seeking bankable, domestically manufactured panels in 2025, Silfab is the clearer choice, particularly given its Tier 1 status and IRA eligibility. ARTsolar is not a realistic alternative in that market - it is purpose-built for the South African and broader African context, where local-content mandates make it a meaningful competitive option that Silfab simply cannot match.
