This[1] is one version of agrovoltaics. The solar panels act like window blinds. They can be configured to follow the sun but also can be configured to “provide optimal shade/cooling throughout the day”.
Erm, I can see a greenhouse. I think they are made to increase temperature for the plants and not to protect from extra sun. Strawberries like sun and would not benefit from shade, unless we are talking about very intense sunlight and not much water.
Most plants usually want as much sun as they can get, so long as the temperature stays in their desired range and enough water is avaiable. So in dry places with lots of sun, acrovoltaics can make some sense, or for plants that like indeed shade, like tomatoes. But it is really not a magic bullet for growing corn and harvesting electricity at the same time.
Sheeps grazing under solar panels seems like a working solution that does not need too much effort around it.
Greenhouses can tame the sunlight, and usually they are painted in white in regions of too much sun (https://m.youtube.com/watch?v=Rl6tMOU84tk). Also, greenhouses are hot but very humid, so the plants doesn't dehydrate as fast.
I could imagine an scheme that instead of watering (costs money) you shade the crops with panels (earns money) during the worst of the day.
What’s in OPs image is a greenhouse. The sides can be closed if low temperatures are coming in at night.
