ARTsolar vs SEG Solar - 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 is a South African company founded in Durban in 2010 by Eshu Seevnarayan, Patrick Goss, and Nhlanhla Zondo. It presents itself as South Africa's only locally owned solar panel manufacturer, though court proceedings in 2025 raised questions about the degree of local production versus assembly of imported components. Its Durban facility is rated at 340 MW following a March 2025 partnership with JA Solar, with bankability historically tied to the reputations of technology partners rather than an independent BloombergNEF Tier 1 designation. SEG Solar was founded in 2016 and is headquartered in Houston, Texas. It holds a confirmed BloombergNEF Tier 1 designation, most recently reaffirmed for Q1 2025, and had shipped more than 7.5 GW of modules globally by the end of 2025, with active production capacity of approximately 6.5 GW and additional U.S. plants under construction targeting over 10 GW of combined domestic capacity. On institutional footprint, SEG Solar is the substantially larger and more globally recognised player.
ARTsolar's product range is oriented toward the South African residential and commercial market, and its panels are positioned to qualify for local-content requirements under South Africa's REIPPPP independent power producer programmes. Its current lineup uses high-efficiency large-format modules produced in cooperation with JA Solar. SEG Solar serves a broader mix of utility, commercial, and residential customers across North America, Europe, and beyond. Its existing modules rely on TOPCon cell technology, and the company has announced a new SIERRA N series using HJT cells reaching up to 740 W and roughly 23.8% conversion efficiency, positioning it toward the premium end of the mainstream market.
For a buyer outside South Africa, SEG Solar is the more practical default in 2025 - it carries independent Tier 1 bankability, a demonstrated global supply chain, and a growing domestic U.S. manufacturing footprint that matters increasingly for IRA-related incentives. ARTsolar is a compelling choice specifically for South African projects where local content compliance is a procurement requirement or competitive advantage, and where JA Solar-grade module quality delivered through a locally chartered entity meets both technical and policy criteria.
