Solar attached to homes is not really a scalable solution on its own. For one thing, it's a massive liability for the utility. Power is produced on an as needed just in time fashion. Putting extra power onto the grid just means that the load is less predictable, and if the utility doesn't have storage, this extra power could be excess, and there isn't a convenient and safe way to dump persistent excess power on a grid level, and they can't phone you up to ask you to shut down your solar arrays either.
This is why you see negative energy prices from time to time. Oversupply is a problem and it can wreck equipment.
