This would vary so much by species of plant, cultivars within species, local climate, etc. I suspect in your case it wouldn’t make sense, but in some places it’s a common practice to shade crops with raised sheets of cloth for example. In those cases, assuming the shading is done fairly consistently (no need to put panels up and down frequently), using panels could be a great idea. Where I live I need all the sun I can get as well. I have to start tomatoes in mid February and get them into the soil in June, and make sure they’re either in my greenhouse where it’s warm or in the most exposed spots in my garden. If I shaded anything my yields would be garbage.
