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 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.

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.

Results of Agrisolar Soybean Pilot Project Revealed by PV Developer 

“French solar developer TSE, in association with Alliance BFC, has unveiled the initial results of a pilot study in France on how solar panels can affect soybean growth. The teams observed solid vegetative growth of the soybeans, with normal flowering, fertilization, and physiological maturation. The six varieties tested presented a diversity of yields: up to 25% difference in yield under the canopy and 19% on the control field.” – PV Magazine 

Oregon Research Studies Use of Vertical PV for Crop Production 

 “There are many different ways to install agrivoltaic arrays. One common method is to raise the array to leave space for farming equipment or livestock to move freely below. Another trending design is to orient the PV arrays vertically, leaving wide open spaces in between the array rows. 

The paper found that an area about the size of Maryland would be needed if agrivoltaics were to meet 20% of U.S. electricity generation. That’s about 13,000 square miles, or 1% of current U.S. farmland. At a global scale, it is estimated that 1% of all farmlands could produce the world’s energy needs if converted to solar PV.” – PV Magazine 

Research Shows Translucent Solar Panels Optimize Crop and Solar Harvest 

“Associate professor Majdi Abou Najm from the Univ. of California, Davis, tested organic solar panels made from translucent material that absorb the blue light to generate electricity, but allow the red light with its longer wavelengths to pass through to the crops below. 

At the UC Davis Agricultural Experiment Station, Abou Najm and his team planted three different plots of processing tomatoes, a common central valley California crop, under a canopy of selective red light, another of selective blue, and a third uncovered plot. 

GNN has reported before on the recent phenomenon of ‘agrivoltaics,’ a practice of growing shade tolerant crops under solar panel arrays. The shade protects the crops from heat stress, while the plants’ transpiration humidifies the air beneath the panels, cooling them down and increasing their electricity output.” – Good News Network 

How current and future research can help us understand the role of pollinator-friendly solar in biodiversity conservation.

In this first episode of the AgriSolar Clearinghouse webinar series, NREL’s Jordan Macknick, James McCall, and Haley Paterson join us to discuss the context and costs of agrivoltaics in the United States.

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.

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 chosen tomato crop.
