A growing trend is emerging at the intersection of renewable energy and sustainable agriculture – solar grazing. This practice involves using sheep to manage vegetation on solar farms, providing a win-win solution for both farmers and solar developers.
Solar grazing offers numerous benefits:
• Sustainable land management: Sheep naturally control vegetation without the need for mowing or herbicides, reducing emissions and chemical use.
• Dual land use: Grazing allows agricultural production to continue on land used for solar energy, maximizing land efficiency.
• Cost savings: Solar operators save on vegetation management costs while farmers gain additional income from grazing fees.
• Improved solar performance: By keeping vegetation low, sheep help maintain optimal sunlight exposure for solar panels.
• Soil health: Sheep grazing and manure improve soil quality over time.
• Rural economic opportunities: Solar grazing creates new income streams for farmers in areas with solar development.
Growing Adoption
The American Solar Grazing Association reports that solar grazing has expanded rapidly, with over 500 solar sites now using sheep across the U.S. Major solar developers like Lightsource BP and Clearway Energy have embraced the practice.
“We’re seeing tremendous interest from both the solar and agricultural sectors,” said Lexie Hain, executive director of the American Solar Grazing Association. “It’s a perfect example of how renewable energy and sustainable farming can work together.”
Success Stories
In Seneca, New York, Nate Chittenden runs a flock of 150 sheep that graze rotationally across 200 acres of solar arrays. The arrangement provides a steady income stream that has allowed him to expand his farming operation.
“Solar grazing has been a game-changer for our farm,” Chittenden said. “It’s opened up new opportunities while letting us continue our agricultural traditions.”
Looking Ahead
As the solar industry continues to expand, experts predict solar grazing will become increasingly common. Research is ongoing to optimize grazing practices and quantify the environmental benefits.
“Solar grazing exemplifies the kind of innovative, multifunctional land use we need to address our energy and agricultural challenges,” said Dr. Joshua Pearce, Director of the Michigan Tech Open Sustainability Technology Lab. “It’s a model for how we can make our energy systems more sustainable and resilient.”
With its ability to combine clean energy production, sustainable land management, and rural economic development, solar grazing represents a promising path forward in the transition to a more sustainable future.
