Actually, with climate change in the back of the mind, covering fields with solar panels (not 100%, only partially) will reduce heat damage and water usage in the height of summer, and also protect the ground during cold spells of winter. So it is not that stupid after all.
That covering car parks with solar is a good idea is completely independent of this.
Plants need direct light to grow… most need full sun. Personally all the solar farms I’ve seen just “grow” grass and everything is kept trimmed down to not cast shade on the panels. Putting the panels up higher would still cast any plants grown in deep shade. I think putting them in places deep shade is needed/wanted on the ground makes sense and because cities tend to be hotter due to paving using solar panels to cast shade would help lower the temps in cities, lowering power usage on things like AC. I think integrating solar into urban landscapes is the future
They need direct and indirect light, and agro-panels have a coverage of about 50%. Not enough for high-end farming, but more than enough for grass and similar to grow for grazing. Or some herbs that need shadow to grow properly. Those panels are usually placed on land that can’t be used for high-performance farming, anyway.
One can always do this. Quite some of those plants love shadow and half-shadow environments. And, as i stated in my original post, don’t ignore the climate change. Many plants growing in a given location for ages will have difficulties in the future because of the more extreme weather.
You can either change the plants you are growing (like people in the south of my country who replace wineyards with olive orchards), or you can help historically local plants to survive, and solar panels is actually one way to do this.

Except for all the plants that evolved and thrive in the low light beneath tree foliage. Evolution is not so picky as a pretty houseplant.

Plant butterfly bushes and other pollenator attractants / nectar sources.

That’s only true, if the solar panels are not properly adjusted to this use case.
The solution for that is https://en.wikipedia.org/wiki/Agrivoltaics#Spectrally_selective_modules
Crazy thought: put solar panels over A/Cs and tie it into the panel.
