If the car has, say, a 300 mile range, and the fixed generation system makes an average of 50 miles of range per day and you drive an average of 50 miles per day, that's going to be pretty much optimal -- even though the batteries are never going below 80% of full charge. > That is why NET metering is the best economics hands down. Fully agreed -- but, of course, only where it's an option. It's the rate plan I'm personally on. However, thanks to intense private lobbying by the Koch Brothers...were my neighbors to install similar systems today, though they'd technically be on a net metering rate plan, they'd actually wind up spending 80% of whatever they do today regardless of how much net they generate. The new plans have insane instantaneous peak / load factor / etc. surcharges that're guaranteed to make rooftop solar a complete waste of money. Utilities are doing this in a _very_ shortsighted attempt to prevent grid defection...but it's too late. Already, my neighbors would have about the same return on investment if they cut the grid connection and went to batteries as they would have a couple decades ago with grid-tie solar. The cost of a grid connection for new construction is so insane that it can't even pretend to compete with battery-backed solar; the grid hookup alone can cost more than the batteries, maybe even more than the total solar+battery installation cost -- and that's before you consider the value of a lifetime of free unmetered energy. So...the grid is going to die, and it's the utilities themselves that are going to kill it. It's a shame...but at least we all get limitless free electricity (after initial capital investment) no matter what happens to the grid.
