A lot of plants doesn't like and cannot survive the sun at central hours unless you water them like crazy. Basically you are watering to avoid dehydration, but not producing, like drinking in the desert. A lot of plants evolved to thrive near/under trees. 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 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.
