Even if the power lines are already a given and you're just looking at the operational cost, home solar still uses them a lot to send power back. Peak usage hours are in the evening when the sun is already down.
Also, home solar is still subsidized, even in Arizona where it makes the most natural sense. I doubt it'd be a thing otherwise, even if the only alternative were utility solar. But I understand the argument that pollution is an overdue emergency and any clean energy is better than nothing.
