Farmers demonstrate successful agrivoltaics, combining solar energy and crop production.
A new study from Michigan State University reveals that farmers can enhance their income by integrating solar energy with crop production, a practice known as agrivoltaics. Focusing on California farmland, the research indicates that installing solar panels can increase revenue while allowing for continued crop growth. The findings also highlight potential challenges to food production and land use, emphasizing the importance of supportive policies and collaborative efforts in implementing this emerging agricultural trend.
East Lansing, Michigan – A new 25-year study from Michigan State University (M-S-U) reveals that farmers can profitably combine crop production with solar energy through a practice called Agrivoltaics. The research primarily focused on California farmland, suggesting that the simultaneous use of solar panels and crops can increase farmers’ income without compromising food production.
The findings indicate that farmers who installed solar panels on their properties generated more revenue per acre than those who did not. This approach is especially effective when solar technology is deployed on low-yield acres, such as land with poor soil or areas that receive excessive shading. By incorporating solar panels into their agricultural practices, farmers can enhance their income while continuing to produce food.
One of the key systems highlighted in the study is Net Energy Metering (N-E-M), which allows farmers to connect to the power grid. This system enables them to offset their electricity needs and sell any surplus electricity back to the utility at a reduced rate. This dual-source revenue model could be a game-changer for agricultural operations across the state and beyond.
California’s Central Valley, the focal point of the research, significantly contributes to national and global food supplies, particularly for orchard crops. However, the region faces challenges including severe drought and over-allocation of water resources. Despite the potential for solar installations to create additional income streams, a notable concern arises: the loss of agricultural land dedicated to solar energy might worsen food security by reducing land available for crop production.
Researchers estimated that the land currently reserved for solar panels in California could have supported approximately 86,000 people if it continued to be used solely for agriculture. Some farmers have also raised concerns that the shading from solar panels may adversely affect crop growth and yield.
The research team, led by M-S-U graduate student Jake Stid, aims to expand exploration into the synergies between solar arrays and agricultural output. This effort could significantly contribute to the national conversation about sustainable land use. Agrivoltaics is gaining traction in North America as a potential high-profit solution for farmers and ranchers looking to diversify their income sources and improve land use efficiency.
Experts emphasize that effectively implementing agrivoltaic systems will require addressing key areas, including financing, policy frameworks, and educational support for farmers. Projections for the agrivoltaics market indicate it could grow to a value of $9.3 billion by 2031, with a compound annual growth rate of 10.1%.
In response to this emerging agricultural trend, various collaborations and initiatives are underway to develop policies ensuring that agrivoltaics can coexist with traditional farming practices. The U.S. Department of Agriculture (USDA) is engaging in research related to agrivoltaics, including a substantial $10 million grant aimed at investigating its potential at the University of Illinois.
Additionally, some projects have begun integrating grazing livestock, such as sheep, into solar energy installations to help manage vegetation and allow for efficient dual land use. Community reactions to solar energy proposals vary significantly, necessitating comprehensive planning and regulations to address local concerns and ensure the successful integration of solar technology with agricultural production.
As the landscape of farming evolves, studies like the one from M-S-U illustrate the promise of combining solar energy with traditional agricultural practices, potentially leading to a more sustainable and profitable future for farmers in the U.S.
