The International Landscape of Solar Farms and Agrivoltaics

Rebecca A. Efroymson, Environmental Scientist, Oak Ridge National Laboratory); and Jonathan M. O. Scurlock, Chief Adviser for Renewable Energy & Climate Change, National Farmers’ Union of England and Wales

Solar photovoltaic (PV) power, the most popular form of renewable energy on farms, is being adopted all over the world. Growers and processors of food worldwide have a long history of using the sun’s energy to produce and dry their crops, and solar PV is adding a modern twist to our relationship with the sun. It is no surprise that some of the best locations on Earth for harnessing solar energy are often ideal places for agriculture and horticulture. However, intelligent design for multi-purpose land use can alleviate real or perceived conflicts between energy and food production. Solar modules can shade crops where light intensity is in excess of crop requirements, reducing water evaporation; they can be mounted on agricultural buildings to power farm business energy needs; and they can export low-carbon electricity to meet wider demands for “green” power and the transition to a “net zero” global economy.

We use the term agrivoltaics broadly to describe any combination of agricultural activity and solar electricity production, but outside the USA, the term usually refers more specifically to the intimate juxtaposition of solar modules and agricultural land use. Examples include PV modules mounted at a height of several meters to allow access to land below by farm machinery or large livestock, where they provide shelter from storms or excessive solar radiation, and the integration of solar PV into greenhouses for crop protection.

We caught up with a range of projects across three continents to report upon their objectives and their future prospects.

Around 30% of British farmers have either rooftop or ground-mounted solar energy. The National Farmers Union (NFU) aspires to the goal that every farmer and grower have the opportunity to become a net exporter of low-carbon energy. The falling capital cost of both solar and battery electricity storage has resulted in a growing pipeline of solar installations across a range of sizes, including large 100-hectare (ha) and 1,000-ha solar farm projects, largely independent of government policy support. The NFU advises farmers that solar PV can be deployed across entire fields, as small, ground-mounted installations around field margins or adjacent to farmyards, on farm buildings, and on domestic rooftops. Developers of solar farms are encouraged by the NFU to follow best practice guidelines for multi-purpose land use, combining energy production, continued agricultural management such as grazing, and creation of wildlife habitat. NFU’s strong preference is for large-scale solar farm development to be located on lower-quality agricultural land, avoiding as much as possible the most productive and versatile soils. Roof-mounted solar systems in Britain continue to offer a sound investment, making between 10% and 25% simple return on capital annually at current electricity prices, depending on how much of the generated power is used on-site. At of the end of 2021, about 70% of the United Kingdom’s 14 gigawatts of solar power generation capacity was located in the agricultural sector.

In the Netherlands, the Symbizon project at Almere, near Amsterdam, has brought together a Swedish energy company with Dutch researchers and a private organic farm to construct a 700-kilowatt solar park with alternating strips of PV modules and rows of crops. Starting in spring 2023, the production of herbs will be investigated, and potatoes, beans, beetroot, broccoli, and grains may be included in this pilot study. Pivoting double-sided (bifacial) solar modules will catch the reflected light from soil and crops.

Nearby in Germany, Goldbeck Solar is an innovator in solar agrivoltaic structures. The company has developed a system of solar PV arches that slide on side rails, allowing farmers to shelter or expose various crops. Typically oriented east to west for maximum solar energy yield, the arches span up to 9 meters, at a height of 2.5 to 3 meters, allowing a degree of control over temperature, humidity, and light. These agrivoltaic modules can also provide shelter for livestock from extreme weather, such as high temperatures and hail. The modules are currently undergoing trials in the four-year Sunbiose project in the Netherlands, which had already succeeded in growing raspberries under the partial shelter of solar PV modules. 

Agrivoltaics are being tested in East Africa, where their shade can reduce heat stress and water loss, and farmer incomes in disadvantaged rural communities may be improved. An experimental facility opened in 2022 in Insinya, Kenya, through partnership with Universities of Sheffield, York and Teesside in the United Kingdom, the Stockholm Environment Institute, World Agroforestry, the Centre for Research in Energy and Energy Conservation, and the African Centre for Technology Studies. Some 180 PV modules, each 345 watts, have been installed about 3 meters above the ground, allowing a variety of crops to be grown under the shade from the strong equatorial sun. Geoffrey Kamadi of The Guardian reports that benefits include improved yields of cabbage, eggplant, and lettuce; a reduction in water loss; and a reduction in high daytime temperatures and UV damage.

Small-scale agrivoltaic development (less than 0.1 ha) has progressed rapidly in Japan, producing 0.8% of the total solar power generated in the country in 2019. Japan has perhaps the greatest number of agrivoltaic farms to date, with more than 120 plant species being cultivated on agrivoltaic farms. The Solarsharing Network provides a catalog of 27 agricultural crops (Solar Sharing for FUN | SOLAR SHARING NETWORK| Solar Sharing Association of Japan (solar-sharing.org) and their light needs. Innovative crop systems include tea, according to Makoto Tajima and Tetsunari Lida of the Institute for Sustainable Energy Policies.

One pilot agrivoltaic project in New Zealand is seeking low-growing flowering plants like alyssum to attract bees and reflect light up to rows of bifacial PV modules. The high energy demand of irrigation systems can benefit from on-farm solar energy. In New Zealand, as in the U.S., UK, and Australia, sheep and other small livestock graze under solar modules, avoiding the need for mowing. As New Zealand reporter Delwyn Dickey notes, the success of such large-scale agrivoltaic systems (i.e., solar farms) may be determined by an insistence upon dual land use during the consenting process and the willingness of solar energy development companies to adopt dual land use.

Clearly, from small-scale intimate mingling of solar PV with agricultural production to multi-purpose land use in the largest of solar farms, the merits of harvesting the sun’s energy twice are appreciated the world over. The outlook for agrivoltaics is bright indeed.

Luminescent Enhancement for Combined Solar and Commercial Agriculture

This project developed a new racking/mounting system combined with a new specialized solar panel for low-cost implementation in a hybrid high tunnel greenhouse. The project successfully demonstrated that high value crops can successfully be combined with solar electricity production, even resulting in improvements to yields for certain crops.

Rainwater Management in Agrivoltaic Systems – Research & Development Potential

Agrivoltaics is a concept in which a piece of land is simultaneously used for both energy and food production by mounting photovoltaic modules at a certain height above (or in between strips of) agricultural land. A local and system-level incorporation of water management is imperative to the sustainable implementation of agrivoltaics. Water raining on the module can be gathered and used for distinct purposes: groundwater recharge, crop irrigation, and cleaning and cooling of the PV modules. This research provides an initial overview of positive and negative impacts for each water use concept and outlines issues that should be taken into consideration and the potential for research and development. Various Managed Aquifer Recharge (MAR) technologies are a way to clean and store the water periodically in an underlying aquifer. Irrigation increases yield within the plant level and therefore increases the system’s output. Thanks to the power supply generated by the PV modules, high-tech irrigation systems can be implemented in agrivoltaic systems; the special adaption of irrigation systems to agrivoltaics poses significant potential for research and development. Meanwhile, the necessity, i.e., profitability of cleaning and/ or cooling PV modules depends on local environment and economic factors. Several cleaning techniques have been developed to mitigate soiling, ranging from manual cleaning to fully automatic cleaning systems. In agrivoltaics systems, the soiling risk can increase. Semi-automatic systems seem to have the greatest potential for agrivoltaics, because they can be used with farming equipment. Multiple cooling techniques have been developed to decrease cell temperature to increase power output, with some of them involving water. Water flowing over the module surface is a promising a promising cooling technique for agrivoltaic applications. Attaching a perforated tube to the upper edge, the entire module can be covered in a thin film of water which cools very effectively (while also cleaning the surface). A closed-circuit system could be created involving the technical components used for rainwater harvesting. The economic feasibility of cooling panels in agrivoltaic systems needs to be investigated. In certain locations, rainwater-harvesting could also be relevant for ground-mounted PV systems.

AgriSolar News Roundup: Agrivoltaic Research in Australia, Solar and Farmland Compatibility, Agrisolar Development in Oregon

Australian Researchers Develop Solar Panels Optimized for Agrisolar  

“University of New South Wales researchers have teamed up with Tindo Solar to develop a line of semi-transparent modules, specialized for agrivoltaic cropping, which will use nanoparticles tuned to capture different parts of the light spectrum. ‘There is evidence you don’t need the full spectrum and some plants will work even better if you provide them with only part of the spectrum,’ project lead and UNSW Associate Professor Ziv Hameiri tells PV Magazine Australia. Crucially, he says, the project will also open a line between farmers, solar researchers and industry, creating the potential for mutual benefits.”  – PV Magazine 

Agrisolar Operations Show That Solar Does Not Compete with Farmland 

“In short, Agrivoltaics is a rapidly growing branch of the energy transition. It is being applied to all manner of crops across the world. All kinds of benefits are emerging, with China even using it to reverse desertification. Not only is it expanding clean energy production, it is providing a vital second income stream for farmers. Banning it would cut off a really important opportunity for Britain’s farmers, at a time when rural poverty is a real issue.” – Green Peace 

Oregon State Develops 5-Acre Agrisolar Project 

“Oregon State University has started construction on a $1.5 million research project to optimize dual-use, co-developed land hosting solar photovoltaic arrays and agriculture. The five-acre Solar Harvest project is located at Oregon State’s North Willamette Research and Extension Center in Aurora, Oregon, 20 miles south of Portland. The 326-kW project is the result of a partnership between Oregon State and the Oregon Clean Power Cooperative, which developed the solar array and financed the construction of the solar array.” – Solar Power World 

AgriSolar News Roundup: Solar and Taxes in NC, Dutch Agrisolar Research, Agrivoltaics in Maine  

Solar Projects Increase Tax Revenue in North Carolina 

“Proposed large-scale solar facilities continue to draw opposition in North Carolina from critics who argue that swaths of panels are blights on the landscape and threaten farms in a state where agriculture is the leading industry. But those facilities have become a financial boon to local communities, particularly in rural areas with limited sources of tax revenue, a newly released study from the N.C. Sustainable Energy Association found.” – Greensboro 

Dutch Research Studies Agrisolar  

“During a four-year pilot project, Dutch independent research organization TNO, in collaboration with Vattenfall and Aeres University of Applied Sciences (UAS), is developing a sun-tracking algorithm that monitors various factors, such as crop yield, energy yield and the effects of herb strips, weather forecast, energy price and soil condition.” – Vattenfall 

Small Farms in Maine are Good Candidate for Agrivoltaics 

“Maine’s prevalence of small farms with low-lying, hand-harvested crops makes the state a good candidate for blending solar energy and food production on the same land, but farmers may not take the risk without funding for pilot projects. 

Maine may be uniquely positioned for this emerging field, known as agrivoltaics or dual-use solar. Nationally, most successful projects so far have involved extras like solar grazing or pollinator habitat alongside panels at small farms with low-lying, hand-harvested crops — precisely the type of farms that dominate much of Maine’s agricultural sector.” – Energy News 

AgriSolar News Roundup: Agrisolar Refrigeration, Pennsylvania Agrisolar, New Zealand Agrisolar Development  

African Company Provides Agrisolar Refrigeration 

“A company called AkoFresh is providing solar-powered refrigerated storage that it says extends the shelf life of perishable crops from about 5 days to 21 days. This will boost seasonal income for farmers by more than $10 million, as well as reduce greenhouse gas emissions by 15%. Farmers can rent a space in the cold store for a daily fee of $0.30 per 20-kilogram crate of produce or take up a weekly subscription. They can also pay for the cold storage with crops instead of cash.” – World Economic Forum 

Research Being Conducted at Pennsylvania Agrisolar Site 

“In recent years, the environmental management of solar farms has become an exciting area of academic research, to assess how different practices affect the productivity of solar and agricultural enterprises and the land on which they operate. Two studies seeking to answer research questions around these topics are currently underway at Lightsource bp’s Nittany 1, 2 and 3 solar projects in Pennsylvania.   

All three sites were designed and are being actively managed to boost biodiversity and support pollinator populations, in addition to generating clean energy for Penn State and their students. Lightsource bp seeded the sites with a mix specifically formulated by the American Solar Grazing Association (ASGA), in partnership with Ernst Conservation Seeds and Pollinator Service. The seed mix, aptly named ‘Fuzz and Buzz,’ was designed to support pollinator species at solar sites, in addition to flocks of sheep. At Nittany 1, more than 700 sheep are managing vegetation through rotational grazing, an example of agrivoltaics, or co-located solar and agriculture.” – Lightsourcebp 

 New Zealand Solar Farm Will Host Sheep 

“Harmony Energy New Zealand has been granted approval to develop a solar farm in the Waikato which will generate electricity to power 30,000 homes as sheep graze underneath. The Environmental Protection Authority (EPA) has approved Harmony’s proposal for approximately 330,000 solar panels to be installed on 182 hectares of a 260-hectare site at Te Aroha West. The land will remain in the ownership of Tauhei Farms Limited, with livestock grazing continuing with sheep, rather than the current dairy herd.” –https://www.stuff.co.nz/business/300693453/hauraki-solar-farm-that-could-power-30000-homes-gets-green-light Power Technology 

Solar and The Future of Farmland

By David Murray

In the 1940s, my great-grandfather purchased a small farm in the Hudson Valley of New York. He raised chickens and grew tomatoes, strawberries, and other crops until he passed away. My extended family treasures this farm, but with every passing year, maintaining it becomes less economic. The temptation to sell the property gets stronger.

Thousands of small farmers across America share my family’s story. The agriculture industry is increasingly consolidated, moving to a large, corporate business model. Farming technology has advanced rapidly, leading to crop prices are driven low. Small, independent farmers are often pushed out of the market. Meanwhile, real estate development in rural areas and suburban sprawl creates a pull: from 2001 to 2016, the U.S. converted 11 million acres of farmland to non-agricultural uses, with low density residential land use as the primary driver.

On one hand, the trend is unsurprising: as we become more efficient at growing food, we require less land – and fewer people – – to farm. On the other hand, small farmers play an important role in our food system, and families like mine should be able to pass a successful operation down to the next generation. For many families, solar energy provides that opportunity.

Leasing land to a solar developer provides stable, consistent income, helping some farmers avoid having to sell the land, which often gets converted to housing, commercial real estate, or other uses. In this manner, solar energy protects against what conservation organizations fear the most: low-density, suburban sprawl.

Solar energy development can also preserve the land: after approximately 30 years, the next generation can convert the property back to agricultural use. Finally, many farmers are already accustomed to supporting America’s energy needs: over 30 million acres of farmland are used to grow corn for ethanol.

Of course, farmers need to think long term: what are the impacts to the land from solar development? One benefit is nutrient runoff: solar facilities require less fertilizer than most crops; thus, nutrient runoff from solar facilities is typically less than the pre-existing agricultural use. Native grasses and legumes also mitigate erosion and improve water quality by intercepting sediment and nutrients. Solar development also cuts down on pesticide and insecticide use. Herbicide may be used during the site preparation process, but more sparingly once the facility is in operation. For arid regions, solar reduces water use – leaving an increasingly valuable resource to neighboring farming operations.

However, for families like mine that want continue using our farm to grow food and feed, agrivoltaics provides an exciting opportunity. This is why the American Clean Power Association is happy to work with the National Center for Appropriate Technology’s AgriSolar Clearinghouse to make agrivoltaics an increasingly financially feasible option for farmers.

Solar grazing is a bright spot. While letting sheep into an active power plant comes with a unique set of challenges, in certain cases it can be cheaper than a traditional landscaping crew. Data from the American Solar Grazing Association shows smaller projects are more likely to use solar grazing, but the association recently noted that a 200-megawatt (MW) solar project is slated to incorporate sheep into its vegetative management plan. For sites where solar grazing works, it can be an excellent win-win-win.

In the meantime, the industry is working to bring down costs of other forms of agrivoltaics, such as crop production underneath panels. A key challenge is raising the height of solar panels to accommodate farming. Unfortunately, raising solar panels significantly increases costs, as the piles need to be taller and driven further into the ground. Expensive machinery – such as a scissor lift – is needed to install piles deep enough to ensure they are secured properly to resist heavy winds. These lifts are not designed for use on solar sites. Furthermore, this process requires more labor to successfully deploy the equipment. This is an example of a major challenge that ACP is excited to work with NCAT on to make agrivoltaics more widespread.

We are aiming for a future where many types of agrivoltaics can scale, while ensuring that solar energy remains one of the cheapest forms of new energy generation. Thus, ACP will continue engaging with NCAT to identify ways to bring down the costs of agrivoltaic projects and continue to foster partnerships between the solar industry and agriculture sector.

AgriSolar News Roundup: Vermont Agrisolar Study, Agrisolar Research in Maine, Wisconsin Dairy Farm Goes Agrisolar 

Vermont Agrisolar Study Shows that Saffron Grows Well Under Solar Panels 

“A study released earlier this year summarized the results of a three-year experiment conducted by the University of Vermont. The research concluded that, given the right soil conditions, saffron grows well in the aisles and at the edges of a solar array, which could boost bottom lines for farmers by allowing them to draw dual revenue streams from a single section of land. 

‘We could see diversified vegetable growers growing lots of spinach and kale, but they weren’t making any money at it because everybody was growing the same thing. We felt saffron offered an opportunity for these growers to add a high-value crop,’ said Margaret Skinner, a researcher at the University of Vermont.  

According to the study, “when soil conditions are suitable, saffron can be grown successfully within a conventional tilted solar array, generating between $7,500 – 130,000 per acre.” – Energy News Network 

University of Maine Studies Agrisolar Blueberry Yield  

“A farmer in Maine has teamed up with a solar developer and university researchers to find out how his (blue)berries fare when partially shaded by solar panels. The University of Maine is studying this example of dual-use agrivoltaics.  

The solar installation was developed by the Boston-based solar developer BlueWave, and it is owned by the company Navisun, which makes lease payments to the landowner. Sweetland tends, harvests, and sells the blueberries, and shares profits with the landowner. 

The university (Maine) received grant funding to continue the study for three more years from the Northeast Sustainable Agriculture Research Education program, which is supported by the U.S. Department of Agriculture’s National Institute of Food and Agriculture. The research team will compare the blueberry yield among the plants fully shaded by panels, plants partially shaded by panels and plants with full sun. The panels are 8 feet tall in rows spaced 8 feet apart.” – Canary Media 

 Wisconsin Dairy Farmer Finds Financial Safety in Agrisolar  

“Brent Sinkula, president of the Manitowoc County Farm Bureau, understands the challenges Wisconsin dairies are facing. The changing dairy market has made it more difficult for small and mid-sized farms to continue. Without plans to expand the dairy, Sinkula was looking for another way to maintain the family farm. In 2018, an energy company approached him interested in renting 500 acres, about a third of his land, to install solar energy panels.  

For Sinkula, hosting solar panels on his land provides a financial safety net for the farm. He’s not the only farmer to make similar arrangements. Farmers have what solar energy companies need: land. Across the state, partnerships between dairy farms and energy companies are increasing, changing the landscape and providing farmers extra revenue in a sometimes unpredictable market.” – WPR 

AgriSolar News Roundup: Solar Sheep, Five C’s of Agrivoltaics, Illinois Team Developing AgriSolar Game  

The Solar Industry’s Mower of Choice: Sheep 

“The panels blanket nearly 1,500 acres of a solar farm in Deport, a town near the Oklahoma border. Ely Valdez, the boss, makes sure prairie grasses don’t block sunshine from the panels. His sheep do most of the work. Sheep, the surprise workhorse of renewable energy, are generating several million dollars in annual revenue tidying up solar farms nationwide. 

‘It’s changing all of our lives,’ said Mr. Valdez. He expects the flocks he oversees to soon generate several hundred thousand dollars in annual revenue. The number of acres of solar fields employing sheep in the U.S. has grown to tens of thousands from 5,000 in 2018, according to estimates by people in the business. Flock owners charge as much as $500 an acre a year. 

The solar industry auditioned several methods for the job, but requirements weeded out expected contenders. Power mowers, which can’t maneuver easily enough under panels to avoid the risk of damaging equipment, are of limited use. “Sheep truly are the appropriate technology for this,” said Michael Baute, vice president of regenerative energy and carbon removal at solar developer Silicon Ranch Corp., based in Nashville, Tenn.” – The Wall Street Journal 

The “Five C’s” of Agrivoltaics 

“These are among the most important findings of an ongoing agrivoltaics research project called Innovative Solar Practices Integrated with Rural Economies and Ecosystems (InSPIRE). Led by the National Renewable Energy Laboratory (NREL) and funded by the U.S. Department of Energy’s Solar Energy Technologies Office, InSPIRE has just completed its second, three-year phase of research into the synergies between solar energy and agriculture.  

In its first phase, InSPIRE tried to quantify the benefits of agrivoltaics and record some early best practices in the emerging field. The project adopts a big-tent approach to agrivoltaics, welcoming any dual use of solar-occupied land that provides ecological or agricultural benefits. That could mean grazing cattle or sheep, growing crops, cultivating pollinator-friendly native plants, or providing ecosystem services and restoring degraded soil.  

The InSPIRE project found five central elements that lead to agrivoltaics success, summarized as ‘the five C’s’: 

  • Climate, Soil, and Environmental Conditions — The ambient conditions of a location must be appropriate for both solar generation and the desired crops or ground cover.  
  • Configurations, Solar Technologies, and Designs — The choice of solar technology, the site layout, and other infrastructure can affect everything from how much light reaches the solar panels to whether a tractor, if needed, can drive under the panels. “This infrastructure will be in the ground for the next 25 years, so you need to get it right for your planned use. It will determine whether the project succeeds,” said James McCall, an NREL researcher working on InSPIRE.  
  • Crop Selection and Cultivation Methods, Seed and Vegetation Designs, and Management Approaches— Agrivoltaic projects should select crops or ground covers that will thrive under panels in their local climate and that are profitable in local markets.  
  • Compatibility and Flexibility — Agrivoltaics should be designed to accommodate the competing needs of solar owners, solar operators, and farmers or landowners to allow for efficient agricultural activities.  
  • Collaboration and Partnerships — For any project to succeed, communication and understanding between groups is crucial.” –  NREL 
  •  

Illinois University Team Developing Interactive Agrisolar Game  

“A team led by University of Illinois, Urbana-Champaign researchers is developing an educational game it hopes can inspire future farmers to think differently about solar power. The app aims to teach kids the emerging concept of agrivoltaics, in which agricultural production is combined with solar photovoltaics. The game will be backed by science from the growing niche of research looking into how solar panel placement affects the growth of various crops.  

‘Dual-use land is really a great idea, intuitively, so why not build an app that lets kids explore these really interesting ideas while they’re playing a game?’ said H. Chad Lane, associate chair for educational psychology at the University of Illinois, Urbana-Champaign. 

Think Farmville, but instead of gamifying every aspect of running a farm, it will focus on the interaction between crops and solar panels. Researchers are discovering that several plant types can perform better when partially shaded by panels; for others, the reduced production can be offset by extra revenue from selling solar power to the electric grid.” – Energy News Network 

Community AgriSolar: Merging Agrisolar and Community Solar 

Merging community solar and agrisolar could aid the Department of Energy’s (DOE) goal of saving $1 billion in energy costs through community solar by 2025. Not only would merging community solar and agrisolar help DOE reach that goal, but would also provide other opportunities and benefits such as the regeneration of soil on solar sites, reducing fuel-operated maintenance demands, and increasing the likelihood of future solar development(s). 

What is community solar? 

Community solar could be an ideal method for low-income households who might be looking to use solar energy and use Low-Income Home Energy Assistance Program (LIHEAP) assistance to pay for their energy bills. LIHEAP funds cannot be used for things like up-front installation costs of typical solar participation methods (non-community solar) or the household ultimately owning the solar equipment. Community solar participation eliminates these issues due to the solar farm and panels not being developed, owned or operated by the LIHEAP recipient.  

LIHEAP Participants Would Lead to More Energy Savings 

Community solar often includes what is known as subscription-based community solar programs (SBCSPs), where a household “rents” solar panels and uses solar energy without the associated conditions and costs of installing solar panels, operating them, or owning them. These conditions of using solar energy typically would not qualify a low-income household to use LIHEAP funds for solar fuel. However, SBCSPs could provide a way for low-income households to be able to use LIHEAP benefit payments for solar fuel through subscription-based community solar programs because the household would not ultimately own the equipment or have to pay for its installation or maintenance costs. 

If LIHEAP participants are eligible for SBCSPs, then more people can participate in saving energy by using community agrisolar, which ultimately assists in the identified goal of the Department of Energy (DOE) in reaching $1 billion in energy savings through community solar by 2025. 

Why merge agrisolar with community solar? 

Community solar has been identified by DOE as a method of reaching energy savings goals by 2025, which includes saving $1 billion in energy costs. Merging agrisolar with community solar developments would not only aid in significant energy savings but would also make future solar developments more likely to be approved—expanding energy savings even further. 

Agrisolar operations like the Cabriejo Ranch in Missouri has shown that agrisolar provides a variety of energy saving methods as well as regenerating the land used by solar farms. The ranch uses Dorper sheep to manage the vegetation on solar operations, which drastically reduces the use of fuel-operated maintenance equipment typically used to manage vegetation. The sheep not only reduce these energy costs, but dramatically increase the health of the soil .  

The likelihood of a solar farm being approved for development is higher when Agrisolar is incorporated into the operations. This was seen in the Garnet Mesa project that was denied due to concerns about losing valuable farmland to the solar-farm development. The project was approved after changes were made to include 1,000 grazing sheep on the solar farm. 

The Possibilities of Merging Agrisolar and Community Solar   

 More participants saving more energy would be a win-win for reaching energy-and-cost savings goals.  

Not only do energy savings goals have a higher likelihood of being achieved through merging community solar and agrisolar, but other benefits of using agrisolar would also be made possible, such as regenerating soil health through grazing practices and supporting  job creations in local communities such as grazing management and farm operations jobs created in Missouri. These benefits of using agrisolar in solar development increases the likelihood of future solar developments by proving the land can be effectively utilized while occupied by solar equipment and operations.
