You charge the car up at night while you're sleeping.

Domestic power isn't enough to recharge the batteries.
Depends how long you want to charge. A simple calculation is that a Tesla battery is 80kilowatt-hours. That means from dead-flat it will take:
80 hours at 1Kw
40 hours at 2kw - standard power point
25 hours at 3.6kw - 15A socket
2 hours from a 40Kw threephase supply (assuming you dont use anything else)
And before anyone tells you it is cheap... at 35c/kwhr the mains electricity will cost you $25 for a full charge. Cheaper than petrol of course but not free or even close. And dont listen to the wankers that say you can just use 'free' solar energy from your $10,000 10Kw solar system because you will need to charge during the day (rather than drive it) and run your house on mains power.
It isnt some magic solution.
Stop talking facts.
These are some figures I worked out some time ago and ran past a sparky:
Assuming 85KWh battery.
Standard 10amp socket gives 2.4kW and will take 36 hours to charge the battery. Charging the Tesla uses the same amount of electricity as 24 x 100W light bulbs.
A 2kW solar setup, assuming a "Peak Sunshine Hour" figure of 5 hours per day (that seems to be an average figure in Australia) will take nearly 9 days to recharge the car. (And your car will need to be home during the day)
That "full tank" will get you up to 500km, and cost you $21 at the 25c tariff 11 (and half that if you only charged at the 13c Tariff 31 rate) Meanwhile, an equivalent family car running at say 10L/100km would cost $65 for the same distance. (A third of the price)
In the real world, a daily 30km round trip to work and back will take around 2 hours of charge to replenish the battery and every 15km driven is the equivalent of running a 100W lightbulb for a day.
The hybrid Camry would cost $40 to travel that distance without aircon running.
