At this point it is all hypothetical. From what I've read this idea of charging a delivery fee to home solar arrays is just an idea submitted by one entity. It is no where near a reality as of yet. The way it sits right now in Maine is : If it ever gets to a point that over 1% of power is produced by home solar or wind, then they will revisit the "trade 100% even" program.
Yes, a smart meter can tell when and how much power is sent to the grid.
If you produce 90% of the power you use, logically some of it would go to & from the grid. What's the chances that you would use all 90% during the day, during the sunny part of the day? I'd think very slim. Certainly some of it is going to go out to the grid, for trade or sale, whatever the deal is with your power company.
