You've got a big error in the translation from square feet to square miles. You need to square the 5280 first, before doing the divide. Resulting in 3.75 sq.miles.
Even if it was 19,800 sq.miles, the panels are not flat on the ground. They are raised and angled, allowing light to reach the ground. Grass still grows. Evaporation is reduced, which is often beneficial to grass. Animals can still graze amongst the panels.
