You wouldn't charge the car directly from the panels. Sell the solar electricity to utility during the day and get a plan for off-peak power (which are often 1/2 or 2/3 of normal rates) to charge your car while you sleep.
(Thats not saying you couldn't charge the car through your solar panels in a pressing case of zombie apocalypse. Inverters for home solar installations output the same AC power as a normal power outlet)

- jacquesm 14y agoThat depends on the inverters. Plenty of inverters can operate in 'island mode' for off-grid applications. You will have to have a lock-out installed that needs to be engaged before island mode will work if you are normally grid-tied. To avoid you hurting people or trying to power the nation in case of a black-out.
