OK, so the Tesla energy solar wall solar panel stuff on the call today, how does that impact the ability of hopes to use car as back up power or to power the grid? My guess is it is not part of the plan. Anyone have thoughts on this?
You would need to hang your charge unit off your PowerWall not off your existing circuit breaker... seems quite doable if the PowerWall has/will have supporting hardware built in. I guess the question is whether they care to go that way. If everyone who gets solar gets a PowerWall, then V2G only helps if an outage exceeds the capacity of your PowerWall(s) plus whatever solar generated during the outage. Plus, depending on lifetime available charge cycles, it's not clear you want to use your Nickel vehicular battery over your Iron PowerWall battery.
The window of advantage seems to get smaller and smaller for V2G... unless it turns out to be more profitable to timeshift the energy with autobidder and a VPP -- and that adding the car's battery lets you take more advantage of that without meaningfully impacting the remaining range as charge cycles accumulate.
