Iowa to study if crops and solar panels can coexist
Iowa State University researchers are launching a new agrivoltaics study — or ag production that's under or between solar panels.
Why it matters: The research could help increase support for large-scale renewable energy farms by showing how ag and solar can coexist on the same land.
Details: The $1.8 million, four-year grant from the U.S. Department of Energy (DOE) will take place on a 10-acre Alliant Energy solar farm being built this year between Ames and Des Moines.
- Horticulture research begins in full in spring 2024 with vegetables, fruits and bees being raised among the panels.
- Economists will then calculate whether the crops can be profitable.
State of play: There's little data out there on what plants may thrive in solar fields, Ajay Nair, an associate professor of horticulture, recently told ISU's news service.
- Five agrivoltaics projects in other states have also been awarded grants.
The big picture: The U.S. will need to quadruple the amount of solar energy installed per year by 2030 to achieve long-term environmental goals, the DOE estimates.
- Solar at those levels will require less than .1% of the land in the contiguous U.S., but might create local land-use competitions with agriculture.
