Wisconsin Farmers Adopted Sheep For Solar Maintenance
Livestock grazing has helped manage vegetation around solar panels in Wisconsin as a sustainable alternative to mowing.

Do you support using livestock to manage vegetation at local solar farm sites?
Wisconsin farmers are increasingly using sheep to graze vegetation at solar power sites, a practice that maintains land health while supporting renewable energy infrastructure. The method is currently active at sites across the state including projects in Fond du Lac and Grant counties.
Why it matters
By keeping grass short, sheep grazing prevents vegetation from shading panels, which can improve solar energy production efficiency by 5-10 percent. The practice offers a lower-cost, ecological alternative to traditional mechanical mowing at large-scale solar installations.
The American Solar Grazing Association reports over 500 solar grazing sites exist across the U.S., covering 200,000 total acres. While the practice has scaled rapidly, the long-term efficacy compared to conventional mechanical vegetation management is still being evaluated.
The players
Beau Stafford
An organic farmer managing solar grazing on 109 acres in Wisconsin.
Alliant Energy
A utility provider utilizing sheep for vegetation management in Fond du Lac and Grant counties.
American Solar Grazing Association
A trade organization that supports the integration of livestock and solar energy production.
We Energies
An energy provider that previously piloted and subsequently ended grazing projects in Texas.
The details
Sheep graze the vegetation beneath ground-mounted solar panels, ensuring grass remains short enough to avoid interfering with solar energy collection. Fencing is installed around these sites to protect the livestock from local predators while they perform this maintenance. While effective in many environments, the practice is not universal, as shown by We Energies, which discontinued solar grazing at two infrastructure projects in Texas due to safety concerns.
Timeline
Annual sheep grazing season occurs mid-April through October.
ASGA held a workshop in the Madison area in September 2026.
State elections in November 2026 may influence future grazing incentive programs.
Health Landscape
The integration of solar grazing represents an evolution in industrial land management, moving away from heavy machinery and herbicides toward biological solutions. This shift aligns with broader industry standards established by the American Solar Grazing Association to maximize land utility.
If you live near solar infrastructure, you may notice livestock grazing in your local community as a non-chemical method of land maintenance. If you are concerned about land management practices near your residence, this is a topic worth discussing with your local utility provider.
The takeaway
Solar grazing uses sheep to maintain vegetation, which can improve the efficiency of solar panels by 5-10 percent. Residents interested in renewable land use can track local utility policies regarding vegetation management to see if this practice is being implemented in their area.
What happens next
Wisconsin legislators may consider state financial assistance for solar grazing programs following the state elections in November 2026.
