- Silicon Ranch tests livestock grazing under active solar energy infrastructure
- Software-controlled panels create space for safe movement of large livestock
- Livestock rotation allows simultaneous grazing and power generation in the paddocks
This small solar farm in Christiana, Tennessee, looks like many others from a distance, but beneath its black panels are lush pastures instead of gravel.
The 40-acre facility, owned by Silicon Ranch, allows a small herd of cattle to spend their days munching on grass and resting in the shade.
The ranch is testing whether livestock can coexist with power generation without removing farmland from active use, with a setup that introduces a variation of agrivoltaics, one that extends beyond crops and sheep into larger livestock systems.

Ingenious software solves the size problem
This project, which began in late April 2026, represents the first serious attempt to integrate livestock grazing with solar energy production on a working 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 for solar installations, as these animals can weigh more than half a ton and risk damaging expensive equipment.
Solar panels normally rotate at near-vertical angles to catch the sun’s rays, leaving very little room underneath for large livestock.
Simply raising the panels would require prohibitive amounts of steel and significantly increase construction costs.
Silicon Ranch solved this problem by developing custom software that workers activate to turn the panels nearly horizontal whenever livestock are grazing.
The system currently rotates 10 cows and their calves between different paddocks every few days.
This allows ungrazed sections to generate approximately 5 megawatts of electricity for a rural electric cooperative.
Financial pressures make this an urgent experience
American agriculture is facing a truly challenging time for farmers due to trade wars, weather extremes and rising costs.
The USDA projects that total revenue from animal products will decline by $17 billion in 2026, with revenue from chicken eggs falling by 66% and milk by almost 13%.
“Agriculture is in a very difficult situation right now,” said Ethan Winter of the American Farmland Trust.
“So maybe this is the time where we can help states meet their energy needs and do it in a way that provides new opportunities for farmers.” »
Farmers can earn about $1,000 per acre by leasing their land for solar installations, which is about 10 times more than regular farming usually generates.
Anna Clare Monlezun, a rangeland scientist working on the Tennessee project, observed that “there is more win-win than compromise” in this arrangement.
Pastures under solar panels retain more moisture and become more drought tolerant, while grazing in shade makes livestock less prone to heat stress.
These animals may gain more weight and drink less water than cattle living on open pasture.
By 2024, sheep were already grazing on more than 130,000 acres of solar sites across America.
However, extending to livestock requires overcoming additional design challenges and developing appropriate economic incentives for livestock producers.
The growing demand for electricity from rapidly expanding data centers requires new energy sources that do not emit carbon.
If this Tennessee experiment proves successful, advocates say solar projects integrated with livestock grazing could “help cattle ranchers conserve their land and livelihoods” while offsetting billions in financial strain.
