This Tennessee solar farm lets cattle graze under panels using smart software while farmers chase survival in a brutal agricultural economy
- Silicon Ranch tests cattle grazing beneath active solar power infrastructure
- Software-controlled panels create space for large livestock movement safely
- Cattle rotation enables simultaneous grazing and electricity generation across paddocks
This small solar farm in Christiana, Tennessee, looks like many others from a distance – but beneath its black panels lies lush pasture 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 power generation without removing farmland from active use, with a setup that introduces a variation of agrivoltaics, which extends beyond crops and sheep 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 working farm.
Nick de Vries, the company’s chief technology officer, acknowledged that “we know it works, but you need to prove it to other people.”
Cattle present a unique challenge for solar facilities because these animals can weigh more than half a ton and might damage expensive equipment.
Solar panels normally pivot to near-vertical angles to capture the sun’s rays, leaving very little room underneath for large livestock.
Simply raising the panels would require prohibitively large amounts of steel and drive up construction costs dramatically.
Silicon Ranch solved this problem by developing custom software that workers activate to turn the panels close to horizontal whenever cattle are grazing.
The system currently rotates 10 cows and their calves between different paddocks every few days.
This allows ungrazed sections to generate roughly 5 megawatts of electricity for a rural electric cooperative.
Financial pressures make this an urgent experiment
American agriculture faces a genuinely difficult moment for farmers due to trade wars, climate extremes, and increased costs.
The USDA forecasts total animal product cash receipts will decline by $17 billion in 2026, with chicken egg revenues dropping 66% and milk falling nearly 13%.
“Agriculture is in a really tough spot right now,” said Ethan Winter from the American Farmland Trust.
“So maybe this is our moment where we can be helping states meet their energy needs and do that in a way that’s providing new opportunities for farmers.”
Farmers can earn about $1,000 per acre by leasing their land for solar installations, which is roughly 10 times more than regular agriculture typically generates.
Anna Clare Monlezun, a rangeland scientist working on the Tennessee project, observed that “there are more win-wins than trade-offs” in this arrangement.
Pasture beneath solar panels retains more moisture and becomes more drought-tolerant, while grazing in the shade leaves cattle less prone to heat stress.
These animals can gain more weight and drink less water compared to cattle in open pastures.
As of 2024, sheep have already grazed on more than 130,000 acres of solar sites across America.
However, scaling up to cattle requires overcoming additional design challenges and developing appropriate economic incentives for ranchers.
The soaring electricity demand from rapidly expanding data centers requires new power sources that do not emit carbon.
If this Tennessee experiment proves successful, advocates believe solar projects integrated with cattle grazing could “help cattle producers hold onto their land and livelihoods” while offsetting billions in financial pressure.
