Have you thought of putting solar on your roof with storage to collect the extra energy you produce during the day and then dump it into your car at night? Yea

Have you thought of putting solar on your roof with storage to collect the extra energy you produce during the day and then dump it into your car at night?
Yeah, there are efficiency losses along the way, but two points:
- More and more net metering tariffs are homeowner-buys-at-retail-pricing-grid-purchases-back-at-wholesale-pricing... the homeowner value of solar's excess energy is getting less
- In a lot of cheaper EV purchases, the car company still owns the battery packs. This is for two reasons: 1) They sell you on a new battery pack when your range starts to decline after a few years, and 2) They're going to use the degraded batteries as second-life storage products... maybe not good enough to power your car, but more than plenty to provide a cheap powerwall alternative.
The points you bring up about mass charging is true, but once pricing starts to reflect that, that's going to make home storage far more economical (it already makes economic sense in some markets).
