- Silicon Ranch tests cattle grazing under active solar infrastructure
- Software-controlled panels create space for large livestock movements safely
- Cattle rotation enables simultaneous grazing and electricity production across paddocks
This small solar farm in Christiana, Tennessee, looks like many others from a distance—but beneath its black panels lie lush pastures instead of gravel.
The 40-acre facility, owned by Silicon Ranch, allows a small herd of cattle to spend their days munching grass and resting in the shade.
The ranch is testing whether cattle can coexist with electricity generation without removing farmland from active use, with a setup that introduces a variety of agrivoltaics that extend beyond crops and feed into larger livestock systems.

Ingenious software solves the size problem
This project, which debuted in late April 2026, represents the first serious attempt to integrate cattle grazing with solar energy production on a farm.
Nick de Vries, the company’s chief technology officer, acknowledged that “we know it works, but you have to prove it to other people.”
Cattle present a unique challenge to solar systems because these animals can weigh more than half a ton and can damage expensive equipment.
Solar panels usually rotate to near-vertical angles to catch the sun’s rays, leaving very little room underneath for large livestock.
Simply raising the panels would require prohibitively large amounts of steel and dramatically increase construction costs.
Silicon Ranch solved this problem by developing custom software that workers activate to turn the panels close to horizontal as the cattle graze.
The system currently rotates 10 cows and their calves between different pens every few days.
This enables untreated sections to generate about 5 megawatts of electricity for a rural electric cooperative.
Financial pressures make this an urgent experiment
American agriculture is facing a really difficult moment for farmers due to trade wars, extreme climates and increased costs.
The USDA predicts that total cash receipts from animal products will decline by $17 billion by 2026, with chicken egg revenues falling 66% and milk falling nearly 13%.
“Agriculture is in a really tough spot right now,” said Ethan Winter of the American Farmland Trust.
“So maybe this is our moment to help states meet their energy needs and do it in a way that creates new opportunities for farmers.”
Farmers can earn about 1,000 dollars per hectares by renting their land for solar installations, which is about 10 times more than conventional agriculture typically generates.
Anna Clare Monlezun, a rangeland scientist working on the Tennessee project, noted that “there are more win-wins than trade-offs” in this arrangement.
Grasslands under solar panels retain more moisture and become more drought tolerant, while grazing in the shade leaves cattle less exposed to heat stress.
These animals may gain more weight and drink less water compared to cattle on open pasture.
As of 2024, sheep have already grazed on more than 130,000 acres of solar across America.
However, scaling up to cattle requires overcoming additional design challenges and developing appropriate financial incentives for ranchers.
The soaring demand for electricity from rapidly expanding data centers requires new power sources that do not emit carbon.
If this Tennessee experiment proves successful, advocates believe solar energy projects integrated with cattle grazing could “help cattle producers hold on to their land and livelihoods” while offsetting billions in economic pressure.
