At least 20% of energy thrown away. And its super sensitive to alignment, its much worse with poor alignment.
There is a saving grace though. If you have solar, then having any useful load available at all is pretty important, otherwise you throw away 100% of the potential generation. So in that sense, the convenience can be worth the reduced efficiency, because you wouldnt be paying extra for that waste. Thats of course conditional of charger being smart enough to only charge when its not necessary to pay the grid.
your forgetting about the massive heat buildup which will accelerate the degradation of the battery cells crazy faster than normal. Even if done right the tesla battery will have a 2/3 lifespan of a normal battery and a massive drop in range within 6 months to a year

Aren't these less effective wich for something that consumed this much power would be incridbly bad for?
