I'm not sure about that. Home solar will offload unused power to the grid. And the utility will often only give you kWh credits which don't roll over forever. Homeowners are paying for the utility's infrastructure expansion on their own dime and giving them some proportion of free power. The utility goes from being the primary generator of power to being primarily an interconnection system. That means poor people are getting subsidized power from rich people. Throw in the strong incentive for homeowners to perform power arbitrage and the whole system gets more stable.
