Piggyback leafy green patches with solar panels

I notice that leafy produce requires ponderous amounts of water to grow. I wonder, is there any way to reduce this high water usage? Perhaps if we install solar panels over the growing patches of leafy greens as a shade to reduce water evaporation, we could decrease overall water use.

If successful, we probably could extend our experiment to different vegetable/fruit farms. Perhaps the farmers could even make a little extra cash by generating electricity!
