This article provides a methodology for verifying such phenomena (control function) and mitigating them by maximizing solar power generation (objective function). Through a case study located in central Italy, positioned near an airport, it was possible to investigate the design variables to protect the landing air routes and the airport control tower.
This study introduces a new separation model capable of accurately estimating the diffuse component from the global photosynthetically active radiation and conveniently retrievable meteorological parameters.
Realizing that less effort has been made to reconcile solar development with biodiversity conservation, researchers in this article provide a framework that uses a unique land-sharing approach and is based on five pillars that cover key aspects of solar park planning and maintenance: (1) eco-smart siting in the landscape, which considers ecological interactions with the landscape matrix and trade-offs between multiple small vs. fewer large solar parks; (2) eco-smart park layout to address the ecological aspects of the spatial configuration of solar park infrastructure; (3) creation of diverse, novel grassland ecosystems with high ecosystem service provisioning capacity using a trait-based ecosystem design approach; (4) management of the novel ecosystem throughout the lifespan of the solar parks; and (5) ensuring stakeholder engagement to integrate this in a viable business model with high community acceptance.
In this study, researchers used field measurements and a plant hydraulic model to quantify carbon-water cycling in a semi-arid C3 perennial grassland growing beneath a single-axis tracking solar array in Colorado, USA. Although the agrivoltaic array reduced light availability by 38%, net photosynthesis and aboveground net primary productivity were reduced by only 6–7% while evapotranspiration decreased by 1.3%. The minimal changes in carbon-water cycling occurred largely because plant photosynthetic traits underneath the panels changed to take advantage of the dynamic shading environment. The results indicate that agrivoltaic systems can serve as a scalable way to expand solar energy production while maintaining ecosystem function in managed grasslands, especially in climates where water is more limiting than light.
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 paper shares an overview of both active and passive cooling approaches in solar PV applications with an emphasis on newly developed agrivoltaic natural cooling systems.
In this article, researchers propose 19 directly measurable indicators associated with 16 ecosystem services within three major stocks of natural capital (biodiversity, soil and water) that are most likely to be impacted by the development of solar parks.
This research argues that non-negligeable amounts of water can be saved due to the windbreak effect caused by vertical agrivoltaic systems.
