Teslas take a lot of electricity, if they came home with an empty battery how long would it take to recharge the car? I know mostly people just have to top up for their average daily driving 30 to 50 miles but just wondering if it can fully charge an empty battery.
If you're talking about solar panels charging an EV it's more of matter it's as mentioned – they don't necessarily charge the car directly. Solar panels are almost always tied into the home's electrical system. During sunlight the panels supply all the juice and any not used may go back to the electric company for credit (or cash?). During daylight a Tesla plugged in is charged from the panels. At night it's from the electric company.
If the homeowner opts for a battery bank he can keep the daytime charge and use it at night. I'm guessing at any time the batteries are fully charged and the household load is light that excess current is sold back to the electric company.
Actual charge times depend on the Tesla and the particular battery and the charger. You can charger with the 120VAC outleTesla has a Level 2 wall charger they rate at 11KW/48A. I think they say it can fully charge any Tesla overnight. They rate charge times as miles drive per hours of charge. Huh?? I think that's to ease "range anxiety". You get more miles per hours-of-charge with their wall charger than with a 120V outlet.
I have no idea if a home solar array could charge an an 11KW rate or higher. But with it generating during the day and the car charging off peak at night solar could pay for itself the Tesla charging and then some. After I win a Power Ball lottery an EV will be at the top of the list of Next Buys.
