No, growing plants out in the sun is much more efficient than capturing the light with a solar panel and then growing the plants elsewhere.

Installing solar panel above fields to boost the production of both is a thing.

But growing plants in arid sunny regions requires a lot of irrigation, which might offset the benefits of maximizing solar efficiency.
The question was about places you would raise livestock.
Believe it or not, one of the problems deserts have for growing plants is too much sun.

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.

Could there be a balance?

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)

And while I'm thinking about it (and I'm way out of my depth here), but sunlight is a lot more powerful than growlights, is it not? Could power be siphoned to an extent, to supplement growth?
I'm realizing that the loss in the system means this wouldn't make sense. Better to use existing light.
