In this study, researchers sought to characterize crop responses to semi-transparent organic solar cells (ST-OSCs) in greenhouses. Lettuce and tomato crops were grown under three ST-OSCs filters that created different light spectra. Lettuce yield and early tomato development were not negatively affected by the modified light environment. A genomic analysis revealed that lettuce production exhibited beneficial traits involving nutrient content and nitrogen utilization while select ST-OSCs impact regulation of flowering initiation in tomato. These results suggest that ST-OSCs integrated into greenhouses are not only a promising technology for energy-neutral, sustainable and climate-change protected crop production, but can deliver benefits beyond energy considerations.
In this study, researchers examined the impacts of animal agrivoltaics on the thermal comfort and wellbeing experienced by dairy heifers, and the potential benefit of offsetting enteric methane emissions. The shade provided by the solar panels efficiently relieved the heat load on the cattle, cooled off their body surface and skin temperatures, and decreased the costs of thermoregulation. Researchers concluded that 4.1 m2 of solar panels would be necessary to offset the methane emitted by the cows.
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.
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.
This work contributes to agrivoltaic design methodology through a digital replica and genomic optimization framework which simulates light rays in a procedurally generated agrivoltaic system at an hourly timestep for a defined crop, location and growing season to model light absorption by the photovoltaic panels and the crop.
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.
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.
This fact sheet includes information on how current and future research can help us understand the role of pollinator-friendly solar in biodiversity conservation. Without a doubt, considerable amounts of land will be needed to meet future solar energy projections. The current rate of solar energy development has already increased the pressure on land resources for energy generation and other land uses (e.g., agriculture, habitat for biodiversity, etc.). Therefore, sustained development of solar energy will depend on proper siting to avoid ecological conflicts and land-sharing solutions that synergize this form of renewable energy development with other land uses.
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.
This research argues that non-negligeable amounts of water can be saved due to the windbreak effect caused by vertical agrivoltaic systems.
