At Elm Department Photo voltaic Farm, about an hour south of Dallas, Texas, a flock of sheep grazes between a wide area of photo voltaic panels. The flock’s shepherd, Amanda Stoffels, watches about it as the sheep munch on the grass and nap in the shade delivered by the panels.
Stoffels owns this land, but leases it to Lightsource BP, a big solar electricity developer that’s 50% owned by British oil major BP. She earns a continual every month cash flow from the lease payments as perfectly as by means of her grazing deal with Lightsource, which pays her to graze her sheep around the panels, therefore maintaining vegetation in look at.
“It really is a new, contemporary solution to agriculture,” Stoffels states. Her contracts with Lightsource permitted her to quit her 9 to 5 career to come to be a full-time shepherd.
An emerging sector known as agrivoltaics brings together solar energy manufacturing with agricultural activities this sort of as sheep grazing, beekeeping and crop growing. This land management system could assist relieve the pressure concerning farmers and photo voltaic developers, teams that typically have competing land-use interests.
“Even however the United States is a very significant nation with a ton of available land, each individual solitary sq. inch of land is either owned, secured or cherished by someone or many persons. And lots of men and women do not want to see that land improve or transform into something various from what it has been,” explained Jordan Macknick, the Guide Electrical power-Drinking water-Land Analyst for the Nationwide Renewable Power Laboratory.
Agrivoltaic tasks, Macknick claims, could be a sort of compromise. “So agrivoltaics definitely presents us that opportunity to proceed farming, continue on performing these agricultural things to do though also generating thoroughly clean electrical power.”
Amanda Stoffels feeds her flock of sheep at Elm Department Solar Farm in Ellis County, Texas. Stoffels earns money by leasing her land to solar developer Lightsource BP and grazing her sheep all over the panels.

Crop growing on photo voltaic farms is even now a nascent region of research and some farmers however have worries.
“Photo voltaic normally takes some of the best land out of output due to the fact they want land that’s 1% to 4% slope,” stated Tom Koranek, a landowner and beekeeper who leases land to Lightsource and creates honey on the photo voltaic farm. That flat, treeless land is ideal for equally photo voltaic panels and crop output, he claims.
However, agrivoltaic jobs are as shut to a get-earn for farmers and solar developers as we currently have, and as the photo voltaic business promptly expands, industry experts say we can assume to see agrivoltaics increasing ideal along with it.
Opening up new marketplaces
The nation will need to establish out a substantial volume of utility-scale photo voltaic to meet up with its decarbonization objectives. Provided that agricultural land contains 44% of the U.S.’ total land space, lots of solar builders are wanting to cite new initiatives on farms.
“For solar developers, I feel the attraction of agrivoltaics is mainly that it will help with community acceptance and group enjoyment about photo voltaic initiatives” describes Becca Jones-Albertus, Director of the U.S. Office of Energy’s Photo voltaic Vitality Systems Business. “Grazing land in this nation is about a 3rd of all of our land use. And if you might be in a position to make that a twin use with photo voltaic electricity manufacturing, you have now opened up a massive prospective industry place that wasn’t open right before.”
Today, the U.S. has about 5 gigawatts of agrivoltaic projects, encompassing a lot more than 35,000 acres across above 30 distinct states. Though this only represents about 3% of the country’s set up solar potential, it can be a expanding industry, and farmers are getting take note.
“It is really a substantially far better money contribution than growing crops,” mentioned Koranek about leasing his land to Lightsource. “Crops are pretty dangerous. So some many years you might make a great return and other years you might not. And so this is a continual revenue yr each calendar year.”

Lightsource operates a combined 615 megawatts of sheep grazing and solar ability projects, all-around 12% of the nation’s overall agrivoltaic portfolio. The enterprise options to insert an supplemental 1,058 megawatts worth of assignments future calendar year.
Shell is also included in the room by means of its 44% stake in photo voltaic developer Silicon Ranch. The ranch operates 1,300 megawatts of agrivoltaic assignments with an additional 900 megawatts prepared over the subsequent two many years.
Even though most photo voltaic builders decide to lease land, Silicon Ranch buys it outright, generally buying degraded farmland that is no for a longer period in production.
“We want to tell these communities that we are committed for the extensive haul, and we’re heading to become associates of these communities in meaningful techniques,” said Silicon Ranch’s Co-Founder and CEO, Reagan Farr. “So our business model of proudly owning serious estate was a functionality of how we seen this asset class.”
Like Lightsource, Silicon Ranch pays community ranchers to graze sheep on their solar farms. But Farr states the company has encountered a sheep shortage, primary Silicon Ranch to make investments in its own flock, which it ideas to grow to over 30,000 by 2030.
Though there are other players in the domestic agrivoltaic current market these types of as Enel Inexperienced Power and US Photo voltaic, Lightsource and Silicon Ranch keep on being the premier players in the space. American oil majors this kind of as Chevron and Exxon haven’t invested in agrivoltaics.
Photo voltaic as well as crop creation
Whilst it is fairly very well comprehended how to graze sheep and produce pollinator habitats among solar panels, it truly is a trickier prospect to develop crops under and between the panels.
Many crops these kinds of as tomatoes and broccoli can theoretically expand beneath solar panels, but the style and design of the solar array generally requires to be altered, often by elevating the panels so that crops can reach their entire peak. That will get costly, and whilst the economics can operate for little-scale projects in marketplaces with potent photo voltaic incentives, scaling up is a problem.
“I would say provided the current price tag of PV know-how, supplied the existing vitality markets that we have in the United States, it will be very difficult to see crop creation agrivoltaics transpire at a scale even larger than 5 megawatts at a time,” says Macknick.
But even if we will not likely see utility-scale crop manufacturing and solar vitality initiatives at any time soon, there’s continue to a great deal of electricity in this space. The Office of Energy is currently funding six agrivoltaic jobs, with the objective of enabling the deployment of over 1 megawatt of assignments focused on crop production, and in excess of 10 megawatts of projects concentrated on grazing and pollinator habitats.
Lightsource BP says it really is intrigued in getting into crop generation, hoping that a person of its sites can provide as a check task upcoming 12 months. Farr claims Silicon Ranch is not pursuing partnerships but. But no matter what route both of those companies, and their oil field backers, get, neighborhood associations and mutually helpful land-use preparations are heading to be paramount.
“We will need to deliver benefit to the communities wherever we web site these solar arrays, or we’re likely to shed our social license to operate. And that is going to hurt our ability to fulfill some of these very aggressive, renewable energy targets that we have as a region,” explained Farr.
