I know next to nothing about electricity, panels, circuits, and etc. I have taken pics of the panels I have in my house. The main panel is too far away from the driveway (where I want to install a wall charger or an outlet that I can use with a nema 14-50 adaptor.) the sun panel (I think that’s what it’s called) is near my kitchen which will be less than 10 ft from my driveway where I want to install the charger (it will be on the outside of my house since I have no garage). Here are pics of the main panel and sub panel. What costs can I expect to upgrade the sub panel? Do I need to upgrade the main panel as well? First pic is sub panel near kitchen. Other 3 are main
