Research led by the US Department of Energy's National Renewable Energy Laboratory (NREL) has gathered data on interactions between habitat, pollinators, soil and solar energy production at three utility-scale solar projects in Minnesota.
NREL’s Innovative Solar Practices Integrated with Rural Economies and Ecosystems (InSPIRE) team has conducted research at the three sites for the last six years, in what the laboratory says is the longest-ran, most comprehensive assessment of interactions between solar, soil, habitat and pollinators to date.
The findings are presented across three studies, “Environmental Co-Benefits of Maintaining Native VegetationWith Solar Photovoltaic Infrastructure,” available in Earth’s Future, “If you build it, will they come? Insect community responses to habitat establishment at solar energy facilities in Minnesota, USA,” available in Environmental Research Letters and “Little prairie under the panel: testing native pollinator habitat seed mix establishment at three utility-scale solar sites in Minnesota,” available in Environmental Research Communications.
The three solar facilities studied in the papers are the Chisago, Atwater and Eastwood solar sites, which form part of the Aurora solar project, owned by Enel Green Power and located in and around the Minneapolis area. NREL says these solar-pollinator sites are the first commercial, utility-scale solar projects in the US to feature comprehensive research on ecovoltaics.
The research found that prairie restoration activities can occur underneath solar panels. Once prairie vegetation was established, pollinators were observed using the site as much as dedicated conservation land, with evidence pointing towards increased abundance and diversity of both vegetation and pollinators under the solar panels.
