This can make sense to do, but it ends up being a lot less cost effective than utility scale solar. A friend of mine lives off grid in Mexico, and he got double duty out of his solar array by making it a big carport and workshop area. So yeah that totally works. But, if you're going to invest $X in solar, it's better to spend it on utility scale stuff than even commercial versions of covering parking lots. This is because the utility scale operation better amortizes the equipment needed to tie into the grid, as well as operationally will keep the panels clean and working at peak efficiency.
