The company has grown rapidly, reportedly reaching roughly 7 GW of annual manufacturing capacity according to distributor data, and it serves predominantly the North American residential and commercial market. ARTsolar, by contrast, was founded in 2010 and operates as South Africa's only locally owned solar panel manufacturer, running a production facility in Pinetown, Durban with a reported annual capacity of around 250 MW. Neither company appears on the BloombergNEF Tier 1 bankability list as of the latest publicly available information, though Aptos is widely described as bankable by US distributors. On sheer production scale and geographic reach, Aptos carries the stronger institutional footprint. Aptos Solar's core product line is built around its patented Dual Nano Absorber technology, which applies selective-emitter PERC cell design with thin-film enhancements and a split-cell, multi-busbar layout to reduce resistive losses and improve heat tolerance. The range spans roughly 410 W to 580 W and covers both residential all-black panels and larger commercial and utility-scale bifacial modules, with the company having introduced N-type variants in recent product cycles. ARTsolar offers monocrystalline PERC panels in the 545-550 Wp range alongside newer N-type TOPCon modules up to 600 Wp, targeting local residential rooftops and grid-tied commercial installations across southern Africa. Both brands back their panels with a 30-year linear power output guarantee. For a buyer in North America, Aptos Solar is the practical default - it has an established US distribution network, well-documented warranty support, and competitive pricing versus mainstream Tier 1 brands. ARTsolar is the logical choice for South African projects, where local certification, regional support, and economic-development considerations make it a preferred option. The two brands effectively operate in separate regional markets and are rarely in direct competition. \---LINKS--- \- https://www.solarreviews.com/blog/aptos-solar-panels-expert-review \| Aptos Solar panels expert review - SolarReviews \| review \- https://www.energysage.com/solar-panels/aptos-solar-technology/ \| Aptos Solar Technology panels - EnergySage \| review \- https://www.pv-magazine.com/2019/05/27/artsolar-south-africa-must-preserve-its-solar-module-industry/ \| ARTsolar - South Africa must preserve its solar module industry \| article \- https://www.engineeringnews.co.za/article/artsolar-and-ja-solar-driving-south-africas-renewable-energy-revolution-2025-06-12 \| ARTsolar and JA Solar driving South Africa's renewable energy revolution \| article Sources: \- \[Expert Review Of Aptos Solar Panels\](https://www.solarreviews.com/blog/aptos-solar-panels-expert-review) \- \[Aptos Solar Technology Solar Panels - EnergySage\](https://www.energysage.com/solar-panels/aptos-solar-technology/) \- \[ARTsolar: South Africa must preserve its solar module industry - PV Magazine\](https://www.pv-magazine.com/2019/05/27/artsolar-south-africa-must-preserve-its-solar-module-industry/) \- \[ARTsolar and JA Solar: Driving South Africa's renewable energy revolution - Engineering News\](https://www.engineeringnews.co.za/article/artsolar-and-ja-solar-driving-south-africas-renewable-energy-revolution-2025-06-12) \- \[Aptos Solar Technology - Profile & Reviews - EnergySage\](https://www.energysage.com/supplier/25391/aptos-solar-technology/) Written by claude-sonnet from the figures above. ## Other comparisons - [ARTsolar vs A.B.
