I pass a couple regularly, at/near farms outsite the city. There's grass growing, it gets less sunlight than it would without the solar panels but it gets enough light for the grass. The grass seems to be used for hay or something like that. Many plants don't need direct sunlight, they do well with the diffuse light from the clouds. Of course those won't be happy in your desert climate where the sun is strong, they're more the likely to grow well in my native Norway, where there's little direct sun but a lot of diffuse light.
