VomDach finds roofs in Bavaria with no solar panels yet and sells them per roof. baseray makes the same check in Romania and Czechia, with the photo date and the building’s facts.
One record per building in Romania and Czechia: use, floors and construction year, height and volume, a dated solar panel check, a heat card and the company registered at the address.
VomDach uses AI on aerial and satellite images to find buildings in Bavaria without a PV system and shows each roof’s shape, area, orientation and PV status.
