Agrivoltaic systems combine solar energy and agriculture, promoting dual land use. Although grazing sheep in these systems is common, research on intentionally designed pastures to increase production is lacking. This study seeks to compare the herbage growth and lamb production in simple, diverse, and legume pastures in an agrivoltaic system over...

In both agroforestry and agrivoltaics, crops are cultivated under the shade of a top story layer of trees and photovoltaic (PV) panels, respectively. However, the quality (i.e. spectral composition) of the transmitted radiation might differ between the two systems. Tree canopies are green and absorb different spectra selectively, while panels are b...

Animal grazing to control understory herbage growth in photovoltaics sites presents a substantial opportunity for animal and energy production within the same site. However, there is a paucity of information on the effect of field preparation method within solar arrays on the establishment and productivity of pastures. Thus, the current study inves...

Habitat for pollinators is declining worldwide, threatening the health of both wild and agricultural ecosystems. Photovoltaic solar energy installation is booming, frequently near agricultural lands, where the land underneath ground-mounted photovoltaic panels is traditionally unused. Some solar developers and agriculturalists in the United States...

Agrivoltaic systems are designed to mutually benefit solar energy and agricultural production in the same location for dual-use of land. This study was conducted to compare lamb growth and pasture production from solar pastures in agrivoltaic systems and traditional open pastures over 2 years in Oregon. Weaned Polypay lambs grew at 120 and 119 g he...

Photovoltaic solar energy installation is booming, frequently near agricultural lands. Traditionally, the land underneath ground-mounted photovoltaic panels is unused, though some are repurposing it as habitat for pollinating insects. However, the impact of the solar panel canopy on the pollinator-plant community understory is unknown. In this stud...
