Why scientists are studying Volkswagen’s flock of solar-farm sheep in Poland

There’s real science behind the cuteness of Volkswagen’s newest recruits. The carmaker is working with Poznań University of Life Sciences, whose researchers are studying how a flock of 100 grazing sheep at its Polish solar farm affects animal welfare, biodiversity, soil quality, vegetation and the site’s microclimate — including whether shade from the panels actually reduces heat stress in the animals.

The sheep now manage vegetation across an 18.3 MW photovoltaic installation built and managed by Berlin-based Quanta Energy, which spans more than 31,000 solar panels and supplies roughly 25% of the power needs of Volkswagen’s Poznań plant over a full year, and can meet the factory’s entire demand on bright, sunny days.

According to flock owner Justyna Nowak-Gajek, the sheep have settled in fast, splitting into smaller groups and grazing calmly across different parts of the farm — a reliable sign they feel safe, since a threatened flock tends to huddle together instead.

Beyond the research value, the arrangement makes practical sense: grazing trims maintenance costs and emissions while creating habitat for insects and other wildlife, cutting down on the mechanical mowing that would otherwise be needed between the rows of panels.
