The objective of this thesis work is to evaluate the introduction of agrivoltaics in Italy through the study of the effect of the presence of photovoltaic panels on the final yield of potatoes in Ferrara, Italy. The findings of this preliminary study indicate that agrivoltaic systems should be designed while taking into account the need to ensure a minimum level of incident radiation at least in the first two months of cultivation, to avoid an inter-row production drop. Furthermore, photovoltaic panels are not responsible for the absolute low yield in years with unfavorable weather conditions, such as cold years; on the contrary, they may mitigate the damages to the crop by creating an underneath microclimate and the resulting higher temperature, which however is a hypothesis to be verified in more detail in future studies.
In this study, researchers monitored the microclimate, soil moisture, panel temperature, electricity generation and soil properties at a utility-scale solar facility in a continental climate with different site management practices. The vegetated solar areas had significantly higher soil moisture, carbon, and other nutrients compared to bare solar areas. However, the benefits of vegetation cooling effects on electricity generation are rather site-specific and depend on the background climate and soil properties.
This article uses the food–energy–water (FEW) nexus framework to delineate three different perspectives of solar energy development on farmland. The first two perspectives fit into the FEW nexus language of “trade-offs” and “synergies” respectively, arguing that solar energy development either conflicts with agricultural land use and food security or, alternatively, that the two land uses can be co-located appropriately to create agrivoltaic systems. The third perspective is a compromise, arguing that solar energy preserves farmland for future agricultural use.
The aim of this research is to establish how relevant agrivoltaics can be in terms of energy production at regional scale. For this purpose, a methodology is developed to: (i) identify greenhouses using cartographic information systems, (ii) estimate how much of these areas could be covered by solar photovoltaic panels without decreasing the crops production, thus, estimating the optimal photovoltaic cover ratio for different type of crops under different solar conditions by developing a novel set of equations and (iii) evaluate the corresponding photovoltaic power and production.
In this paper, researchers quantify floating photovoltaic impacts on lake water temperature, energy budget and thermal stratification of a lake through measurements of near-surface lateral wind flow, irradiance, air and water temperatures at one of the largest commercial German facilities, situated on a 70 m deep dredging lake in the Upper Rhine Valley, South-West Germany.
This paper looks at the use of photovoltaic thermal air collectors (PV-T) and integrated greenhouse drying systems. It offers insights and data to aid scientists and researchers in the creation and improvement of thermal models for combined solar systems, and presents a detailed analysis of the current state of knowledge in the field of combined solar systems. It also identifies gaps in the existing research and suggests potential avenues for future investigation.
In this article, the authors conducted a qualitative study revolving around three methodological approaches: a press analysis, a review of scientific literature, and fieldwork in the Pyrénées-Atlantiques district in France. Their analysis highlights four main results: (i) agrivoltaism is an innovation conceptualized in techno-scientific arenas which seek to define its agricultural viability; (ii) at the national level, the remote control by the State does not provide a framework for governance capable of involving the various actors in the fields of agriculture and energy; (iii) the deployment of agrivoltaism systems across regions engenders conflict while placing key local actors in a situation of uncertainty with regard to how best to manage this innovation; (iv) while individuals are subjected to territorialization, this paradoxically favors structural policy innovations which outline the contours of territorial governance.
This guide serves to help landowners navigate the complex and challenging decision process of whether to enter a solar lease. It presents key issues to consider and information to gather prior to making a decision, offers communication skills to help guide conversations with others connected to the land, and provides tips and tools for negotiating with the solar company on the terms of a solar lease.

The Agrisolar Policy Guide was designed to facilitate policy learning and innovation in the United States. By collating existing initiatives and key provisions, this guide serves as a resource for regulators, land use planners, decision makers, and others who are interested in state-of-the-art agrisolar policy. The AgriSolar Clearinghouse is impartial towards policy; the intention of this guide is not to advocate for certain initiatives, but to provide a central platform for education and engagement. The goal of this guide is to support policy innovation for better co-location.
