US farmers are dealing with the quadruple whammy of tariffs, inflation, employee shortages, and local weather impacts, resulting in a spike within the variety of bankruptcies this yr. New developments in agricultural science can’t overcome all of these challenges without delay, however a brand new agrivoltaic undertaking in Virginia goals to display that the brand new power crop of the twenty first century — photo voltaic power, that’s — may also help present a lifeline to farmers and native communities in these difficult occasions.

Photo voltaic Panels And The New Power Crop Of The twenty first Century

Power crops have been a well-known characteristic throughout the trendy world agriculture trade for generations, with corn and soybeans at present dominating the manufacturing of ethanol and biodiesel right here within the US. Though a carbon-recycling sustainability case will be made for biofuels, these conventional, land-based crops are industrial operations requiring herbicides, pesticides, heavy equipment, and transportation to and from refineries earlier than they attain the power client.

The UK consulting agency Cerulogy is among the many power analysts to run the numbers on biofuels and carbon emissions, and their numbers say that biofuels should not a very efficient various to fossil fuels. “World biofuels manufacturing emits 16% extra CO2 than the fossil fuels it replaces,” explains the group Transportation & Surroundings, citing a brand new report commissioned from Cerulogy.

“The identical land may feed 1.3 billion folks, whereas utilizing simply 3% of that land for photo voltaic panels would produce the identical quantity of power,” T&E provides.

Certainly. Not like conventional power crops that contain lengthy durations between harvest cycles, photovoltaic panels seize photo voltaic power from the solar and convert it to electrical energy with each passing second of daylight, delivering it on to power customers or to power storage techniques because the case could also be.

The worldwide photo voltaic trade may chip away additional at Cerulogy’s land use estimate of three%, by making use of agrivoltaic rules that allow farmers to proceed utilizing the land in between photo voltaic panels.

Agrivoltaics is a brand new science, rising on the heels of the preliminary photo voltaic growth of the early 2000s. Again then, the price of photo voltaic tools was comparatively excessive and builders minimize their prices by planting photo voltaic panels on beds of low-maintenance sand and gravel, at finest seeding the land with monocrops of clover or brief grasses. By 2018, although, researchers had been compiling ample proof that the shade from photo voltaic panels conserves soil moisture whereas enabling different shade-tolerant vegetation and grasses to thrive, opening the door to a robust new device within the farmland conservation toolkit. Since then, lowering wildfire threat has additionally emerged as a follow-on profit.

So far, most agrivoltaic operations within the US concentrate on livestock grazing, which additionally helps cut back upkeep prices by stopping vegetation from overgrowing the panels. Habitat restoration to spice up pollinator populations can be starting to emerge.

Rising crops for human consumption is a next-level problem, and that’s what the Piedmont Environmental Council in Virginia has got down to sort out. The group’s pilot undertaking at Roundabout Meadows in Aldie, Virginia, surfaced briefly on the CleanTechnica radar final month, when it earned the title “Plan of the Yr” within the 2025 North American Agrivoltaics Awards program. Though the undertaking weighs in on the virtually minuscule measurement of half an acre, NAAA described the forthcoming undertaking as a “deeply strategic set up that might have statewide ripple results,” with the purpose of launching the agrivoltaic area past fields for grazing and pollinator habitats, and into the human meals crop space.

Agrivoltaics In Motion

Exercise on the PEC website was effectively underway by the point NAAA tapped the undertaking for Plan of the Yr, with the photo voltaic panels up and operating together with an onsite power storage system. Final week, PEC kindly emailed extra particulars to CleanTechnica prematurely of a proper launch to be held on October 17.

The power storage part might shock sure high-ranking public officers who doubt that such techniques exist, however there it’s. “The Roundabout Meadows undertaking will embrace a wise panel, which allows the farm to measure power utilization, in addition to on-site battery storage,” PEC notes. The battery will allow onsite tools to proceed operating on photo voltaic power after the solar goes down, together with effectively pumps, fridges, and heated greenhouses.

“Supposed as an illustration website and proof-of-concept for a number of functions, we’ve designed the 42-panel photo voltaic panel set up with 4 rows of greens instantly within the floor to imitate a standard farm setup,” PEC explains, “And 4 in raised beds to make the undertaking equally related to smaller functions, together with city settings, rooftops, and different constructed environments.” Wineries, breweries, and parking heaps are additionally on PEC’s radar.

PEC additionally attracts consideration to the broader context that helps agrivoltaic options for farmers and their communities. “PEC’s agrivoltaics pilot undertaking can be a part of an even bigger story about agricultural and meals system safety and clear power technology, battery storage, and internet metering, all in a state dealing with unprecedented power calls for from knowledge heart growth.”

15 Agrivoltaic Initiatives To Rule Them All

If all goes in keeping with plan (and thus far, it has), the Roundabout Meadows undertaking will display that 42 photo voltaic panels can co-exist with eight rows of greens on a comparatively small plot of land. Put in by the agency Tiger Photo voltaic, the photo voltaic panels are located in three rows of 14 panels every, positioned 12.5 ft aside to permit extra daylight onto the crops. The panels are additionally mounted on excessive racks measuring six ft tall, additional easing entry to the crop rows.

The plantings embrace lettuces and different greens identified to thrive in partial shade, together with sun-loving staples like tomatoes and potatoes. The varied choice will allow the researchers to gather knowledge resulting in suggestions for optimum plantings.

In an in depth article concerning the undertaking final yr, PEC described how the agrivoltaic motion has grown right into a sprawling data base. To launch the brand new undertaking, PEC has drawn upon its expertise participating with different initiatives, photo voltaic trade stakeholders, and conservation teams. The brand new undertaking additionally faucets into Virginia Tech’s agrivoltaic stakeholder group, and it has earned technical help from agrivoltaic researchers on the Nationwide Renewable Power Laboratory in Colorado, by a Clear Power to Communities grant. Final yr, NREL additionally chosen PEC to affix a brand new cohort of 15 organizations conducting next-generation work within the agrivoltaic area.

PEC is already lined as much as make a big contribution to the hassle. The undertaking is designed to generate extra power than the farm at present wants, opening up the potential to switch its present inventory of fuel-burning instruments and tools with electrical ones.
