Fostering Social Acceptance of Solar Through Agrivoltaic Solutions

By Alexis Pascaris

What if we shifted our perspective to view Not in My Backyard (NIMBY) syndrome as an occasion for innovation? What if we strategically integrated local community interests into a solar project, rather than grappling to override them? Luckily, embodying these ideals may not be as lofty as it seems.

Combining agriculture and solar energy production in an agrivoltaic system shows promise as a sensible method to reduce siting conflict, generate rural economic opportunity, and ultimately increase social acceptance of solar. The majority of the solar professionals interviewed in a recent study on industry perspectives about agrivoltaics discussed the great potential to leverage these systems strategically to retain local agricultural interests in project development and consequently gain receptivity in a community. Minimizing threat to existing community interests by pursuing a dual-use project provides a distinct advantage over traditional ground-mounted solar projects, which are often challenged on the basis of land conservation and farm preservation values.

But do solar energy deployment and farmland preservation have to be mutually exclusive pursuits? Can the agrivoltaic solution properly reconcile these competing interests in a way that benefits all stakeholders?

Let’s consider for a moment that we are at a delicate yet opportune inflection point in large-scale solar deployment. Previous case studies exemplify how the community relation component of project development has rippling consequences (both positive and negative) on our ability to sustain the build-out rate of solar. Poorly developed projects perpetuate lack of trust in developers, resistance from rural communities and ag-interest groups, as well as restrictive land use policy. Research concerned with New England’s energy transition evaluated the factors that contribute to energy project outcomes, finding that stakeholder relations is instrumental, and that social conflict is a key contributor to project failure. Collaboratively designed projects that generate co-benefits leave a legacy of community pride and positive perception about solar. The Long Island Solar Roadmap Project demonstrates how the solar development process can be enhanced through stakeholder engagement, which includes incorporating community preferences in project siting and design.

Based on precedence, the path of least resistance is clear – to meet our ambitious renewable energy targets, we must develop innovative, inclusive practices to minimize siting conflict and harmonize solar deployment goals with existing community interests. By upholding community values and agricultural interests in a solar project, agrivoltaics provide a means to enhance development practice remarkably well.

You may say I’m a dreamer, but I’m not the only one. Last spring, we surveyed two U.S. counties to investigate whether public support for solar increases when a project incorporates agricultural production. Survey respondents indicated that they would be more likely to support solar development in their community if it combined energy and agriculture. The study further investigated the importance of a range of planning and development factors – land type, distribution of project benefits, and impacts on local interests were determined to be of highest priority to community members when considering their support for a solar project. These findings imply the importance of community engagement in the planning process and suggest that a solar project designed to maintain the agricultural function of land is likely to experience receptivity rather than resistance – a valuable co-benefit of the agrivoltaic approach.

Thinking long-term about our commitments to sustain the deployment rate of solar not only includes optimizing economic and technical efficiency but fostering social acceptance as well. “Social acceptance” can either be our mighty ally, or a formidable opponent to our solar development pursuits. The agrivoltaic solution illuminates a pathway to alleviate siting conflict, generate localized benefits, and contribute to a legacy of solar projects everyone is proud of.

What if all future solar systems served a greater purpose than electricity generation? Would you be more likely to support them in your backyard?

Examining Existing Policy to Inform a Comprehensive Legal Framework for Agrivoltaics in the U.S.

This study applies Legal Framework Analysis to identify barriers and opportunities for a comprehensive legal infrastructure to enable agrivoltaics in the U.S. e State of Massachusetts is used as a case study to understand what elements of their regulatory regime contribute to their novel agrivoltaic policy program, while also considering the surrounding federal and local government dynamics in which this state program is embedded.

The case study shows that a comprehensive legal framework for agrivoltaics should arguably include a combination of federal and state energy financing mechanisms coupled with favorable state and local land use policies. Specifically, a state-level feed-in tariff and local government allowances for mixed land use between solar and agriculture will be the key features of an enabling legal framework.

The Agricultural, Economic and Environmental Potential of Co-Locating Utility Scale Solar with Grazing Sheep

The study revealed that grazing sheep on solar sites is a cost-effective method to control on-site vegetation and prevent panel shading. At no time in the growing season did vegetation shade the panels. Maintenance was less labor-intensive than traditional landscaping services and, thus, less expensive. The grazing trial at the Musgrave solar site was a full success for the site owners and operators, as well as the sheep farmer.

The aim of this study was to compare economic and agricultural benefits and challenges of traditional land management strategies (mowing, string trimming) with rotationally grazed sheep on solar sites. Sheep were grazed between May and November 2018 to obtain agronomic and economic data, as well as to gather knowledge of the feasibility of grazing sheep on solar sites.

Land Use Conflicts Between Biomass and Power Production – Citizens’ Participation in the Technology Development of Agrophotovoltaics

This paper addresses the concern that despite the technical feasibility of renewable energy technologies and their contribution to climate-friendly power production, public opposition can be a hurdle for new installations of renewable energy installations, including agrivoltaic operations. This study assesses citizens’ perceptions of the Agrophotovoltaics (APV) technology by applying the Responsible Research and Innovation (RRI) concept.

In the workshop conducted in this paper, citizens’ perception on APV before building the first pilot plant was investigated to analyze relevant aspects for the innovation process and its framework at an early stage of the technology development process. This paper describes the impact of APV on landscape, biodiversity, economy, and on the requirements for regulatory framework.

Stakeholder Interactions Around Solarsiting on Agricultural Lands: Toward Socio-Agrivoltaic Interventions

This study includes discussion on key benefits, tensions, and paradigms influencing farmers and farming communities’ decisions to host utility-scale solar generation. The first goal of this study is to develop a conceptual map of stakeholder interaction(s) around utility-scale solar deployment on agricultural lands. The second goal includes the critique of agrivoltaic solutions that fail to consider stakeholder priorities as technological fixes.

Scientists and engineers have recommended agrivoltaics to solve conflicts between land use for energy versus agriculture. The study discusses and focuses on stakeholder perceptions and paradigms about using agricultural land, particularly prime farmland. The study covers the question of how does the existing context of energy and agricultural systems affect solar siting, and how are stakeholders interacting to coproduce decisions?

The results of this study provide a conceptual map of stakeholder interaction on solar development on agricultural lands and argues that agrivoltaics are currently treated as a “technological fix.”

Disney World Set to Use 40 Percent Solar Energy in 2023 

Walt Disney World recently announced its plan to achieve net-zero greenhouse emissions by 2030 by installing two 75-megawatt solar arrays, according to a news release by One Green Planet. These arrays will result in roughly 40% of Disney World’s electricity being powered by solar energy.  

“Our commitment to the environment goes beyond imagining a brighter, more sustainable future by putting possibility into practice to ensure a happier, healthier planet for all,” said Jeff Vahle, president of Walt Disney World Resort, according to the news release. 

The project will include installing roughly 500,000 solar panels, which will produce more than 375,000-megawatt-hours of carbon-free solar energy within a year of operation. Other Disney locations, including Disneyland Paris, are developing solar installations such as solar parking-lot canopies, which reduce greenhouse emissions by 750 tons of carbon dioxide annually, according to One Green Planet.  

Conservation Blueprint, a company that works within the renewable energy industry to design, establish, and manage the final vegetative cover on solar energy projects, has partnered with the team at Walt Disney World to design seed mixtures to be used with the solar energy installations. Peter Berthelsen, a stakeholder with the AgriSolar Clearinghouse and president of Conservation Blueprint, stated, “Creating and managing renewable energy projects with pollinator benefits in mind is a great way to [achieve] environmental sustainability results.” 

The solar arrays will begin operations in 2023. The installation will make Disney the largest commercial consumer of solar energy in the state of Florida. 

Follow the Sun Tour: Learning from Arizona’s Biosphere 2 and Manzo Elementary Agrivoltaics  

By Dr. Stacie Peterson

The interdisciplinary research at Biosphere 2 and Manzo Elementary School in Tucson, Arizona is foundational for agrivoltaics in the United States.  My first introduction to agrivoltaics came from research at these sites, in the article Agrivoltaics Provide Mutual Benefits Across the Food-Energy-Water Nexus in Drylands. The opportunity to tour these sites, meet the researchers, and provide the AgriSolar Clearinghouse network with a way to connect was exciting indeed.

The tour started at the Biosphere 2 site, where Dr. Greg Barron-Gafford and graduate students Kai Lepley, Alyssa Salazar, Nesrine Rouini, and Caleb Ortega described their research, findings, and future projects. Greg provided a background of Biosphere 2, research conducted at the site, its application to agrivoltaics throughout the country, and its correlation to work at the Manzo Agrivoltaic site.    

Kai Lepley and Nesrine Rousini then described their work employing classic plant physiological instruments and novel ground-based remote sensing tools for tracking plant phenology and growth.  Alyssa Salazar described her studies on agrivoltaics impacts to the phenology and growing season patterns of different crops across our growing seasons and how this research can help determine how this approach might extend the growing seasons of certain crops.  Caleb Ortega described his planting approach as well as efficient and creative ways of collecting data.  They then asked the tour to help plant seeds for next years’ agrivoltaic experiments.

After a tour of the Biosphere 2 complex, the group travelled to Manzo Elementary Agrivoltaic site, where Mariah Rogers, Mira Kaibara, Stacy Evans, and Dr. Andrea Gerlak led a lunch-and-learn about the food science, social science, citizen science, student activities, and agrivoltaic food programs.  Mariah’s research involves blind taste tests of agrivoltaic and traditionally grown crops to determine if there are detectable differences in preference.

Stanford University Develops New Solar Cells 

Stanford University engineers have announced that they have developed a new type of solar cell capable of generating electricity not just during the day but also at night, according to a recent report by National Public Radio.  

The new technology includes a device that incorporates a thermoelectric generator, pulling electricity from “the small difference in temperature between the ambient air and the solar cell itself,” according to the report.  

A recent study published by the journal Applied Physics Letters states that the new solar device serves as “continuous renewable power source for both day- and nighttime, and the approach can provide nighttime standby lighting and power in off-grid and mini-grid applications, where solar-cell installations are gaining popularity.”
