Agrivoltaics: The Environmental Impacts of Combining Food Crop Cultivation and Solar Energy Generation

In this study, a Consequential Life‐Cycle Assessment (CLCA) was conducted to holistically assess the environmental consequences arising from a shift from single‐use agriculture to agrivoltaic systems (AVS) in Germany. The results of the study show that the environmental consequences of the installation of overhead AVS on agricultural land are positive and reduce the impacts in 15 of the 16 analyzed impact categories.

Delayed Grape Ripening by Intermittent Shading to Counter Global Warming Depends on Carryover Effects and Water Deficit Conditions

This two-year study aimed to analyze whether intermittent shading produced by panels placed over grapevines can delay grape ripening to counter the impact of global warning on phenology. Researchers concluded that intermittent shading produced by panels can shift ripening into a cooler period compared to unshaded plants. They also state that shading intensity and duration should be adapted to evaporative and soil water conditions to benefit from the phenological delay caused by panels, without altering production in the long term.

Leveraging Campus Landscapes for Public Health: A Pilot Study to Understand the Psychological Effects of Urban Sheep Grazing on College Campuses

In this project, researchers placed sheep on a college campus in an effort to examine the social benefits of grazing lawnscape management. The project sought to determine if the presence of the sheep decreased stress levels among the student body; if sheep grazing events created opportunities for education about well-being and engagement with the community; and if the sheep grazing contributed to the identity of the college campus. The researchers found that the presence of the sheep provided temporary, in-the-moment stress relief for students, and the events fostered a sense of community and placemaking. Sheep grazing did not appear to have an impact on the overall campus identity.

Agrivoltaics In Illinois: A Regulatory and Policy Guide

The goal of this policy guide is to summarize both state and local regulations with implications for those wishing to establish agrivoltaic operations in the state of Illinois. The first part of this guide briefly gives a history of agricultural and renewable energy development in Illinois, as well as details agrivoltaic research efforts by the University of Illinois. The guide then covers local-level policies that will have bearing on agrivoltaic development. The final portion of the guide discusses state-level policy that may impact agrivoltaic development, especially in the instance of installing solar panels on agriculturally classified land.

Agrivoltaic System: Estimation of Photosynthetic Photon Flux Density Under Solar Panels Based on Solar Irradiation Data Using All-climate Solar Spectrum Model

This study focused on the photosynthetic photon flux density and employed an all-climate solar spectrum model to calculate the photosynthetic photon flux density accurately on farmland partially shaded by solar panels and supporting tubes. This study also described an algorithm for estimating the photosynthetic photon flux density values under solar panels.
