I think the commenter was implying that rather than putting it on the roof of people's homes, the focus should be on utility-scale solar power stations.
Solar produces 10x as much power per area than energy crops.
And other than with crops, you can have sheep grazing and have a functioning meadow ecosystem develop below the panels.
Also, how are you planning to grow meadows under solar panels without any sunlight?

The sun moves, and therefore the shadows move. And you need some space between the panels anyways, so they don’t shade each other. Also, grass can grow in the shadow!
The cost of installation is not a problem, because the ROI is greater than the interest on a loan. That’s what banks are for!
