An Angus ranch in southern Oregon has become the test case for a new kind of cattle-friendly solar, hosting RUTE SunTracker’s first commercial project.
The one‑acre, 120‑kilowatt array is the first real‑world installation of RUTE’s patented, cable‑stayed solar tracker designed specifically to coexist with grazing cattle. RUTE supplies the hardware and is also acting as the developer for its first regional cattle‑plus‑solar demonstrations.
What makes the setup different is the clearance. The tracker system provides about 10 feet of headroom, with panel heights reaching up to 16 feet across the array. That gives cattle full access to the pasture underneath while allowing ranchers to keep managing the land as usual. The project is interconnected to Pacific Power’s grid in Jackson County, Oregon.
Projects like this are getting more attention as the solar industry runs into land‑use limits. In the US alone, about 30 gigawatts of new solar capacity installed last year covered roughly 150,000 acres. Meanwhile, the country has close to 120 million acres of cattle pasture, much of it facing rising heat and water stress.
That’s where agrivoltaics come in. By adding solar to working pastureland, ranchers can create a second revenue stream while improving growing conditions for forage through partial shade.
“Within weeks of installing the RUTE canopy, the crew observed leafier forage and increased legume presence inside the array compared to outside,” RUTE president Doug Krause said. “Even on irrigated pasture, direct summer sun can be too intense.”
RUTE’s work has been supported by grants from the US Department of Energy’s American‑Made Solar Prize and the US Department of Agriculture. In October, Oregon State University’s Agrivoltaics Program began quantitative studies at the site to measure pasture production, adding hard data to what ranchers are already seeing on the ground.
Next, RUTE plans to take the project on the road. This winter, the company will present at cattlemen’s association meetings as it looks for ranch partners with onsite electric loads, such as irrigation pivot systems.
“In the near term, our focus is on regional, behind‑the‑meter installations so ranchers and power producers can see the equipment operating in real conditions,” Krause said. “While interconnection timelines are long, these projects allow us to build momentum as we connect with developers and ranches on utility‑scale pipeline.”
