The company entered the photovoltaic business in 2004 and commissioned an automated PV module production line in 2012. It operates at a relatively modest scale, primarily serving the Central and Eastern European market, and no publicly available evidence places it on BloombergNEF or other Tier 1 bankability lists. ARTsolar, by contrast, was founded in 2010 and is based in Pinetown, near Durban, South Africa. It describes itself as South Africa's only fully locally owned solar module manufacturer and has pursued a series of OEM assembly partnerships with major Chinese producers - first LONGi Solar and Talesun, and most recently JA Solar, with whom it opened a 325 MW factory in 2022 and agreed to expand further in 2025. ARTsolar is not itself a Tier 1 manufacturer in the traditional BloombergNEF sense, but its ties to Tier 1 cell suppliers give it a more visible institutional footprint than Selfa on the international stage. Selfa's current product range covers crystalline modules using PERC, TOPCon, and N-type cell technologies, with output ratings roughly in the 410-550 Wp band, and the company markets a proprietary self-cleaning surface coating. Its panels are positioned primarily for residential and commercial rooftop installations in Poland and neighboring European markets. ARTsolar's assembled range has historically spanned mono- and polycrystalline modules from around 100 W to 350 W, though its newer JA Solar-based production shifts toward large-format, high-efficiency panels better suited to commercial rooftops and utility-scale ground mounts. ARTsolar's products are also engineered to meet South African grid standards and domestic-content requirements under the country's Independent Power Producer procurement programs. For a buyer in South Africa in 2025, ARTsolar is the more natural default - it qualifies under local content rules and benefits from JA Solar's cell technology - though the company has faced serious financial and legal headwinds after anticipated IPP contracts did not materialize, so due diligence on its current operational status is warranted. For a buyer in Poland or the EU, Selfa offers a domestically manufactured option with local warranty support, though a buyer prioritizing maximum efficiency or bankability for project finance would likely look to larger global brands first. The two manufacturers do not realistically compete in the same geography. \---LINKS--- \- https://www.pv-magazine.com/2025/06/17/ja-solar-artsolar-agree-to-expand-pv-module-manufacturing-in-south-africa/ \| JA Solar and ARTsolar agree to expand PV module manufacturing in South Africa \| article \- https://www.pv-magazine.com/2022/11/07/talesun-artsolar-open-325-mw-module-factory-in-south-africa/ \| Talesun and ARTsolar open 325 MW module factory in South Africa \| article \- https://www.enfsolar.com/selfa \| Selfa GE S.A. - Poland solar panel manufacturer profile on ENF Solar \| review \- https://www.enfsolar.com/artsolar \| ARTsolar Pty Ltd - South Africa solar panel manufacturer profile on ENF Solar \| review \- https://www.climatescorecard.org/2025/02/artsolar-in-south-africa/ \| ARTsolar in South Africa - Climate Scorecard overview \| article Written by claude-sonnet from the figures above. ## Other comparisons - [ARTsolar vs A.B.
