In dry circumstances with moist winters and shade-loving crops, combining photo voltaic and farming can create a synergistic impact the place each power and crop manufacturing are enhanced. Agrivoltaics, pairing photo voltaic power with farming and ranching–vegetation and livestock–can enhance manufacturing and management wind and soil erosion, enhance pollinator habitat, and promote soil well being. Crops are sheltered from intense rain or hail, a typical drawback on conventional farms. They’re additionally protected against an overabundance of daylight. Extra daylight, not required in sure rising circumstances, will be harvested for power era.
If correctly sited, photo voltaic panels accomplice properly with farming. They are often extra environment friendly on farmland, particularly with trackers, and shade-loving crops could have improved rising circumstances. Rainwater is directed to crops planted under the underside fringe of the photo voltaic panels. Whilst you might not have the ability to pack in as many panels per acre as on a rooftop, the soil and vegetation under the panels cool the panels because of evapotranspiration, which additionally enhances panel manufacturing effectivity. Photo voltaic panels present pollinator habitat in addition to grazing and shade for some livestock, an additional advantage, particularly within the U.S., the place 35% of farmland is used for grazing.1
I just lately noticed an indication within the Lafayette/Erie rural suburbs of Boulder, Colorado, that mentioned, “Say NO to photo voltaic panels on our farms.” I used to be shocked to see this–was photo voltaic being compelled on farms?
Although not a standard analysis supply, I discovered Reddit helpful in distilling the nuanced sentiments of the controversy, based mostly on socio-economics and coverage. One commenter on Reddit addressed the problem: “It amuses me that people who find themselves strongly into property rights consider they’ll inform farmers what they’ll do with their property. The entire world isn’t a HOA.”2
These against photo voltaic argue the economics of land use and property values. Opposition to photo voltaic farms is primarily because of misinformation, conflicts in property rights, land use, financial uncertainties, and cultural values. Cultural worth conflicts are usually rooted in a neighborhood’s identification as rural.
Regardless of the sturdy sentiment of disapproval of solar energy in rural America, credible analysis organizations and farmers are pairing photo voltaic and farming as a win-win. The agriculture business wants modern options like agrivoltaics to make the business extra sustainable by addressing its often-criticized excessive carbon footprint and power consumption.3
Opposition to Photo voltaic Farming
Whereas a lot of the controversy over photo voltaic farms is about land use and easy NIMBY (Not in my again yard) -ism, loads of additionally it is linked to political “tradition wars” the place the opposition is getting their info from oil and fuel proponents who’ve vested pursuits in opposition to renewable power, regardless of how and the place it’s produced.
Rural America doesn’t need to lose its agricultural identification. That is a part of their tradition. Photo voltaic improvement is akin to modernization and industrialization, that are seen by some as basically against a rural way of life. Utilizing the solar as gas nevertheless, is inherent to farming.
Economics
The financial worth of every acre of farmland is straight tied to the price of meals. Photo voltaic can add extra income than “money crops” alone, elevating the worth of the land. Nonetheless, land use for power continues to be only a drop within the bucket, accounting for simply 0.4% of ice-free land globally. And but, nearly 50% of the world’s liveable land is devoted to agriculture.4
Evaluating rising corn for power to photo voltaic manufacturing is not any contest– it takes about 31 hectares of corn ethanol to supply the identical quantity of power generated by one hectare of land coated in photo voltaic panels.5
A number of the opposition just isn’t in opposition to photo voltaic fully, however really feel it needs to be restricted to rooftops and parking tons. Their stance is extra of an “both/or” strategy, as an alternative of “and/together with.” This sentiment highlights a number of the nuances of the general public debate. Agrivoltaics can supply a bridge, offering the perfect of each worlds to farming and clear power.
Propaganda
There may be additionally loads of misinformation being unfold on the market, reminiscent of photo voltaic panels contribute to international warming by reflecting warmth into the ambiance, and photo voltaic panels leach chemical compounds into the bottom under them, each of that are fully unfaithful. A North Carolina city rejected a photo voltaic farm venture out of fears that they ‘suck power from the solar’, and trigger most cancers, each of that are additionally not true.6 Extra doubtless, this concern stems from an total anti-development sentiment. Residents have been additionally involved {that a} close by photo voltaic farm would lower their property values. Usually, the other is true, or builders could make small changes to enhance outcomes. “The parents involved about property worth are usually referring to residence worth, in the event that they stay close by. Research have been constant in exhibiting that close by property values could also be barely elevated or decreased, however it’s a wash. Impacts on the worth of close by farmland is little extra difficult. Adjoining farmland that’s close to interconnection factors, might change into extra useful for additional photo voltaic improvement or for mixed-use agrivoltaics. Its worth for typical farming is prone to stay unchanged, however we’ve heard of instances the place fast photo voltaic improvement can erode conventional rural economies. Group dialog–with out panic–is vital,” in line with Jill Cliburn, who consults with utilities and photo voltaic planners on neighborhood engagement.7
Teasing aside anti-progress from an ”something new” sentiment can rapidly change into political. It’s a troublesome state of affairs as a result of, for instance, it’s straightforward to not desire a information heart in or close to your yard; subsequently not a far stretch to not need the power manufacturing close to you to energy it.
Folks categorical concern of fires, however they don’t appear to be properly knowledgeable about how fires may begin or why they’re, in actual fact, extraordinarily uncommon. The rise in battery power storage programs has created a storm of controversy in some states. That is very true when a hearth does get away in an outdated, substandard battery plant or in a facility used for automobile battery-related manufacture.
Politics
There may be and goes to be a repeatedly increasing want for extra power manufacturing because of the elevated demand for and by information facilities.
Let’s be clear – nobody is being compelled to supply photo voltaic. Nonetheless, there’s concern that laws in lots of states permits energy producers to overrule native zoning choices on main power amenities.
Lots of the voices in these rural areas are voices of opposition. Bedford County (Virginia) Board of Supervisors mentioned, “I’m going to counsel proper now that we make it clear that Bedford County — we have now an important economic system made up of recreation, tourism, and agriculture, and placing photo voltaic panels right here would do nothing however destroy the character of this county. And I’ll inform you proper now, earlier than these sons of b— are available right here and put photo voltaic panels in, I’ll combat to the demise.”8
Others disagreed: “Shift sufficient land away from rising corn (aka cut back provide) and costs will go up.”
Image a farmer who “can’t milk his again 40 for photo voltaic earnings” and subsequently needed to promote his land to a developer who turned it into Walmart. Is that this any higher?
Walmart was introduced up once more in one other submit: “I’ve run into all types of roadblocks in upstate New York. Some individuals simply don’t like seeing them as a result of “we moved up right here to take a look at inexperienced fields and mountains”. They mentioned that whereas the Walmart field retailer was seen down the hill.”
The irony of this conservative viewpoint is that it runs in opposition to a long-held conservative precept: property rights. The issues over authorities energy and its imposition over each how one can and might’t use your land present a nuanced dialogue with many viewpoints which might be typically conflicting. Some counties have imposed caps on how a lot land they’ll enable for photo voltaic improvement or arrange different guidelines that make photo voltaic improvement troublesome.
The objections to photo voltaic fluctuate from place to put, however one objection is constant. Many individuals in rural areas see photo voltaic farms — a time period that’s sadly coming to be considered propaganda — as industrial improvement, incompatible with a rural neighborhood. If individuals needed to look out on an industrial web site, they wouldn’t be dwelling in (fill within the clean with no matter neighborhood is concerned).
Options
Because the Native Individuals taught us, farming is a part of our sustenance, our survival. There’s a connection between the financial and energetic want for farmers to be chargeable for their carbon footprint. Agrivoltaic programs will help farms diversify earnings, present power, and cut back carbon footprint.

Agrivoltaics will help nurse our disturbed lands again to life. In November of 2024, NREL printed the longest-run, most complete evaluation of interactions between photo voltaic, soil, habitat, and pollinators thus far. The analysis discovered that prairie restoration actions can happen beneath photo voltaic panels, with noticed elevated abundance and variety of each vegetation and pollinators.9
“I noticed an indication in a county close to me that mentioned mainly, “You’ll be able to’t feed individuals with photo voltaic farms. Cease power corporations from buying farmland.”
“Because the inhabitants continues to develop, if viable farmland is being purchased and became photo voltaic farms, that could possibly be a problem.”
Studying between the traces: Opposition seems to be to massive photo voltaic farms normally, not essentially agrivoltaic operations which have conventional farming practices.
Professional Photo voltaic Farming Commentary on Reddit:2 “If a landowner needs to place a photo voltaic farm on their land… instantly all people else has an enormous opinion about it. What occurred to respecting property rights?”
“Please inform me how large-scale, intensive hog or poultry farming is LESS disruptive than photo voltaic.”
“That is all floor that we personal, develop crops on, and have been for 50 years so it doesn’t have an effect on anybody however us. I perceive in case you’re shorting another person by signing photo voltaic leases, however that isn’t the case with us.”
“There’s a ‘no photo voltaic on farmland’ signal a couple of quarter mile from a farm area that was bought for 4 McMansions close to Plain Metropolis. Apparently, that’s okay.”
How a lot land is required? By 2050, ground-based photo voltaic might require about 0.5% of the land within the contiguous U.S., in line with the EPA’s Photo voltaic Futures Examine. The examine suggests prioritizing disturbed lands (8% of land) and dual-use land alternatives reminiscent of agriculture.10
Pairing floor mounts with single-axis trackers in addition to bifacial photo voltaic fencing makes use of an excellent smaller footprint.
NREL estimates that the U.S. would meet its renewable power targets if a million acres of farmland have been coated in photo voltaic.11 Agriculture, meals, and associated industries in america whole over $1 trillion, or about 5% of the nation’s GDP. Nearly half (44%) of U.S. land is used for agriculture, and the direct output of America’s farms contributes $134.7 billion, or about 0.6% the the nation’s GDP. Meals and photo voltaic power usually are not at odds; in actual fact, they’re complementary.
I spoke to farmers who voiced their considerations. “What will we do after they don’t work anymore?” By educating that the panels and electronics are changed in 25 years or so, residents will be empowered to be a part of the answer. Others expressed fears of wasted land, not figuring out the key lives of leafy greens, tomatoes and peppers who thrive in partial shade.
Inner champions and advocates are wanted in rural areas in order that the sentiment is one among alternative and fewer of compelled change. Emphasizing the twin use of photo voltaic as an adjunct to farming as an alternative of competitors is central to this dialog.
The extra we will pay attention to one another, the higher we will work collectively to fulfill our power wants sustainably. And as expertise, schooling, and public assist enhance, the higher choices we could have, and the extra agrivoltaics will probably be embraced and deployed on our farmlands to safe
a clear dwelling future.
