Maybe this is a dumb question, but how do you charge a car via solar at night?

- sathackr 6y agoMaybe they work nightshift. Or more likely as with most solar systems they are "grid-tie" Your electric meter essentially runs backwards during the day when you are selling excess power from your panels to the utility. Then you "buy" it back at night when you are drawing more power than your solar panels make.
- javchz 6y agoOption A) In a lot of places, you're still connected in the grid. For the sake of argument let's say, you produce 5 Kilowatt-hour in the day, and only used 2 kWh. The other 3 kWh are sold to the grid in a positive balance for you. So at the end of the month, the bill is: What you consumed to the grid in the night - what you added in the day, so depending on the sunlight you got, there could be months where you pay 0 in electricity bills. Option B) A lot of 18650 batteries and a inverter connected to your home, like the tesla powerwall.
- rekoros 6y agoBatteries is certainly an option, but we sell power to the utility (PG&E) during the day at a high price per kWh and use it at night (between 2300 and 0700) to charge our car (and run the washer) at a low price per kWh.
