> and the grid is the backup power (for charging the battery with off-peak rates) . That way people can avoid paying fees for net generation, and the net metering rates don't matter. You will end up paying a larger grid connection fee. If you touch any part of the grid you are going to help pay for it's upkeep. The traditional model is changing but the grid itself still has extensive maintenance. Want to ensure that some power generation plant 2 states over doesn't accidentally dump a metric ton of electricity and fry every substation between your house and Kalamazoo? Or what happens when your town has an earthquake, tornado, hurricane, blizzard that disables your solar generation, you'll be forced to rely on the grid getting back online to help assist the people that eventually will assist your solar. People will stop paying for generation but I don't believe people realize what goes into keeping this kind of infrastructure up and running safely.
