Answer by Douglas L
how can I charge an electric car with solar power?
First you get enough solar panels to cover one or two football fields. You can buy a step-up transformer to get whatever voltage you want but you must have a charger that takes DC power.
The thing about solar is that it takes a huge number of panels to add up to any significant any power.
