Agrivoltaics is the practice of bringing together agricultural activities and photovoltaics (PV)—using the same land to harvest solar energy and reap agricultural benefits, like grazing, crop production, increased pollinator habitat, and soil health.
The Denver Botanic Gardens now boasts a new 1.2-MW, 4.5-acre agrivoltaics facility at its Chatfield Farms location, which is a 700-acre native plant refuge and working farm about 20 miles southwest of downtown Denver, Colorado.
“When you walk into the space under the solar panels, the crossbars are 8 feet high. Everything is very high up and spread out, and it’s green and cool and shady. The space is organized, and it feels like an easy place to grow things,” Hart said. “There are sunflowers, a group of mourning doves lives there, and native flowers grow around the exterior. And there’s sainfoin, a cover crop that blossoms early in the year and attracts bees. It’s also a legume, so it helps restore soil. It’s not a sterile space.”
For over nine years, researchers from NREL’s Innovative Solar Practices Integrated with Rural Economies and Ecosystems (InSPIRE) project have been researching the colocation of solar and agriculture as part of research funded through the U.S. Department of Energy Solar Energy Technologies Office.
At first, the challenge was to introduce the concept of agrivoltaics to solar developers, researchers, farmers, and the public and address the question, “Does this really work?” Over time, the challenge was to prove that there can be mutual benefits of bringing together solar and agriculture by conducting research on over 20 agrivoltaics sites. Now, NREL researchers are aiming to refine and adapt the practices of agrivoltaics to meet the specific and varying needs of diverse communities and farms.
