Volkswagen is turning to an unlikely workforce to maintain the grounds around its solar farms: sheep. Instead of relying on gasoline-powered lawnmowers, the automaker is increasingly using grazing animals to keep vegetation under control beneath thousands of solar panels at multiple manufacturing facilities.
The latest example comes from Volkswagen’s Poznań plant in Poland, where a flock of 100 sheep has been introduced to manage grass around the factory’s large solar installation. The initiative follows a similar program that has already been operating for several years at Volkswagen’s Chattanooga, Tennessee, manufacturing plant.
While the idea may seem unconventional, it serves several practical purposes beyond simply cutting grass. Sheep reduce the need for fuel-powered maintenance equipment, naturally fertilize the soil, and can safely graze around solar panels without damaging the infrastructure.
Volkswagen also sees the projects as part of its broader environmental strategy. Alongside renewable energy generation, the company is exploring ways to improve biodiversity, reduce emissions associated with facility maintenance, and make better use of the land surrounding its factories.
Poland’s Factory Welcomes 100 New Workers
Volkswagen’s newest grazing program is located at its Poznań manufacturing facility, where an 18.3-megawatt solar installation stretches beneath more than 31,000 photovoltaic panels. On favorable days, the array can generate enough electricity to meet the factory’s full power demand while supplying roughly one-quarter of its annual electricity consumption.
Rather than sending lawnmowers between the rows of solar panels, Volkswagen has introduced approximately 100 sheep to naturally control vegetation throughout the grazing season. According to the flock’s owner, the animals quickly adapted to their new surroundings and have comfortably settled into smaller grazing groups across the site.
The project also supports ongoing scientific research. Working alongside Poznań University of Life Sciences, Volkswagen is studying how sheep grazing affects biodiversity, soil quality, vegetation growth, animal welfare, and the local microclimate, including whether the solar panels provide meaningful shade that reduces heat stress.
Chattanooga Has Been Doing It for Years
The idea is not entirely new for Volkswagen. At its Chattanooga, Tennessee, assembly plant, sheep have been maintaining vegetation beneath the facility’s solar farm for several years as part of a partnership with renewable energy company Silicon Ranch.
The Chattanooga solar installation generates up to 8 megawatts of electricity through more than 33,000 solar panels spread across approximately 60 acres. During full production, the renewable energy system supplies roughly 8 to 10 percent of the factory’s electricity needs.
Around 50 sheep rotate through different grazing areas to prevent overgrazing while naturally trimming vegetation and fertilizing the soil. The site even employs guard donkeys to help protect the flock from predators, allowing the animals to safely work year-round.
Agrivoltaics Offers Multiple Benefits
Volkswagen’s approach is part of a growing practice known as agrivoltaics, which combines agriculture with solar energy production. Instead of dedicating solar farms solely to electricity generation, companies allow livestock to graze beneath the panels, creating productive use for the same land.
Sheep are particularly well suited to the job because they are gentle on the equipment and can easily access areas that conventional mowing equipment may struggle to reach. Unlike goats, which are known to climb on structures and chew cables, sheep typically graze without damaging the solar infrastructure.
Adaptive grazing also helps minimize erosion while reducing the need for herbicides, fuel consumption, and frequent mechanical maintenance. The result is a system that benefits both renewable energy production and the surrounding ecosystem.
Sustainability Beyond Vehicle Production
Volkswagen says projects like these reflect the company’s broader commitment to improving the environmental performance of its manufacturing operations. Renewable energy generation remains an important part of that strategy, but reducing the environmental impact of day-to-day facility maintenance is also becoming a priority.
The expansion of sheep grazing from Chattanooga to Poland demonstrates how relatively simple ideas can deliver practical benefits at industrial facilities around the world. By replacing lawnmowers with livestock, Volkswagen is reducing emissions, supporting ecological research, and finding another way to make its factories more sustainable without relying on additional technology.
