Charging an EV using your own rooftop solar can be relatively easy, but it depends on several factors, the most obvious being the size of your solar system, the time of day, and the weather. If you want to charge an EV quickly using solar only, then you'll need a large enough solar system and some help using a smart charger which we will describe in more detail later.
How easy it is to charge an EV using solar depends on the following factors:
Type of charger used - Charger speeds can range from 2kW to 22kW
Your solar system size - Typical rooftop solar systems range from 5kW to 15kW or more.
