Charging at home with solar is absolutely amazing. We used to wake up to an empty tank and drive on fumes and prayers to the overpriced Shell down the street. Now we wake up to a full tank, every time!
Maybe this is a dumb question, but how do you charge a car via solar at night?
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.
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.
(For power-limited off-grid applications, a smart charger makes a lot of sense. That’s a niche use case.)
