## Summary

Solitek is a Lithuanian solar manufacturer founded in Vilnius, where it built its factory in 2013 and has since grown into the largest solar panel producer in Northern Europe. The company operates at roughly 250 MW of annual module production capacity and recently brought a new fully automated line to full scale, further consolidating its position as a credible European-made option. Solitek does not appear on the BloombergNEF Tier 1 lists that typically cover multi-gigawatt Chinese or global brands, but it holds meaningful third-party credentials including the Cradle to Cradle Gold sustainability certification and the UK Microgeneration Certification Scheme. ARTsolar is a South African manufacturer headquartered in Durban, established in 2010 and billed as the country's only fully locally owned solar panel maker. Its production footprint was recently upgraded to 340 MW per year through a partnership with JA Solar - announced in mid-2025 - which brings Tier 1-grade n-type cell technology into local assembly. Between the two, Solitek has the longer independent track record and a stronger foothold in European institutional markets.

In terms of product focus, Solitek offers a range that spans standard residential and commercial rooftop modules to building-integrated photovoltaic (BIPV) solutions such as its Solid Solrif line, all based on monocrystalline cells with TOPCon and PERC variants confirmed across its portfolio. Efficiencies on newer models have been reported above 22%. ARTsolar's current range centers on large-format monocrystalline TOPCon n-type panels in the 500 W to 600 W class, aimed squarely at residential rooftops and mid-scale commercial or light utility projects in sub-Saharan Africa, with compliance tailored to South Africa's procurement and domestic-content requirements.

For a buyer in Europe seeking a locally sourced, sustainability-certified premium module, Solitek is the natural choice. For projects in South Africa - especially those subject to local content rules under the government's renewable energy procurement program - ARTsolar is effectively the default, and its new JA Solar technology tie-up meaningfully narrows any efficiency gap. Outside their respective home regions, these brands serve very different markets and are not directly interchangeable.
