Can livestock live under solar installations?
There are also studies that show that solar panel above fields can help boost production of both: solar panel get cooled by the plant perspiration and the plant get cooled by the shade of the panel.
Goats climb anything.
Grazing animals probably wouldn't work very well.
Or rather, too much sun for available water. Installing solar panels high enough that goats don't bump into them, and planting shade-tolerant arid plants, can absolutely support grazing.
Some grasses grow with partial light. With the right inter-panel spacing, could it be that a grazing animal might require more space, but not to an unreasonable degree? (I assume there are other considerations for the pasture...ease of finding the animals, moving them around, etc)
