Agrivoltaics, also known as solar farms that allow agricultural activities to occur underneath solar panels, are gaining popularity among farmers and utility-scale solar developers in the United States. While still a nascent , over 50 agrivoltaic projects have been installed nationwide with increasing adoption in recent years. States with notable agrivoltaic activity include California, Maryland, Massachusetts, North Carolina, and New York.

Benefits For Agriculture

For farmers, agrivoltaics provide multiple benefits compared toleasing land only for solar development. Studies show that properly designed solar installations above crops can potentially increase agricultural yields by mitigating environmental stresses. The shade from solar panels reduces soil evaporation and moderates daytime temperatures, creating a more favorable microclimate for many crops. This is particularly valuable as climate change impacts like increased heat waves threaten agricultural productivity in many regions. By simultaneously producing energy and food on the same land area, agrivoltaics also helps preserve agricultural land facing ...

Optimizing Panel Design And Crop Selection

While initial pilot projects revealed design flaws that impacted some crops negatively, subsequent research and field experiments have provided valuable insights into optimizing agrivoltaic systems. Panel heights, percentage of shade coverage, and spacing between rows must be tailored to the specific crops cultivated. For example, lettuce, berries and grape vines have been successfully grown beneath solar panels spaced high (20-30 feet) enough to allow adequate sunlight transmission. Wide- row crops like corn may require wider spacing or partially shaded configurations. Ongoing monitoring helps further refinement.

Financial And Policy Incentives

As the technology progresses, financial incentives are helping accelerate commercial agrivoltaic adoption. Utilities in several states now offer enhanced compensation rates for agrivoltaic projects through renewable energy credit programs. Federal rural energy incentives apply to on-farm agrivoltaic systems. Crop insurance products are also in development to cover production risks. On the policy front, new interconnection standards streamline the approval process for agrivoltaic projects in some regions. With supportive policies and project economics improving, analysts forecast the United States agrivoltaic capacity could surpass 1 gigawatt by 2030.

Case Study: Strongtown Farm, Maryland

One of the earliest and largest commercial agrivoltaic projects in the United States Agrivoltaics is Strong town Farm's 4.5-megawatt solar installation which has powered the farm since 2018. Situated on former tobacco fields in central Maryland, the project combined an analysis of 15 crops to select highbush blueberries as the primary cultivation under elevated panels placed at different heights and angles. Early results found blueberry and pumpkin yields either increased or saw no impact compared to open-field production. The farm now grosses over $100,000 annually from blueberry sales alone. Power purchase agreements with a utility and participation in multiple renewable energy programs provide revenue streams that enhance the overall operation's finances.

Research Initiatives Advancing The Field

Universities and national labs are conducting extensive R&D to address remaining questions around optimal system configurations and co-locating diverse agricultural operations with solar power generation. One key initiative is the US Department of Energy's "Optimization of Dual Use Solar and Agriculture Systems" program focused on engineering challenges, predictive crop modeling and techno-economic assessments. Researchers are quantifying light transmission qualities needed for different crops and investigating methods to spatially distribute light more evenly beneath panels. Studies compare various row orientations, use of reflected light from ground surfaces and effects on soil microclimates. Other areas of examination involve watering requirements, pest and weed dynamics, and applicability to perennial and livestock operations. The research aims to maximize dual land use potential across a variety of agricultural landscapes and climates.

Standardized Research Framework And Knowledge Sharing

To continue advancing the agrivoltaics , experts emphasize the need for standardized frameworks comparing crop and livestock performance across diverse project sites in the U.S. and globally. Developing consistent metrics, data collection methods and collaborative datasets can help isolate design variables that optimize combinations of solar energy generation and agricultural output. Open information sharing strengthens the evidence base informing farmers, developers and policymakers. Multi-stakeholder engagement encourages input from all sides to shape research agendas. With a growing number of projects emerging from California to New York, the opportunity now exists to build an comprehensive research network fostering innovation and knowledge transfer nationwide.

United States Agrivoltaics represent a promising sustainability solution that synergistically combines solar power production with food and crop cultivation. While still an emerging technology, increasing adoption rates across the United States indicate its viability and potential to concurrently address climate change, land use and energy priorities making it an important sector to watch. Continued innovation and collaborative research efforts hold potential to maximize the outputs of these multifunctional solar farms.
