SE Vega ATS

Vega ATS has a Rijeka head-office address but a separate production facility at Ulica rijeke Dragonje 12, Novigrad (Istria, near the Slovenian border on the Dragonja river) -- a rooftop solar plant most plausibly sits on the factory building rather than the Rijeka office, but no source explicitly states this. Medium confidence.
