You're right that it could be constructed in a way that would be more than fair, even attractive. And I would think that some kind of app that let you block out times would solve the "don't drain my battery if I might need it" problem (You could schedule it to be unavailable to the grid on a date when you plan on leaving for a vacation after rush hour, and never enabled on Thursday nights when you drive a long distance in the evening) The GP though is probably right that our [insert expletive] utilities would pull the same type of crap they did nerfing net metering and find a way to rip off those participating in the scheme. Power is worth what, 46 cents a kWh now when I'm buying it, but if I had panels and was selling it during peak A/C usage time, suddenly it's worth 6 cents right. Uh huh.
