Whatever scenario you use, driving 30 miles a day or 300, the battery you charge from needs to be bigger than the battery you discharge to if you want to only use what you captured. And the solar system needs to be scaled to supply more than that much source charge.
You want to be able to put 300 miles into your EV? your power wall needs to have more than 300 mils of charge stored in it. Only need 30 miles of charge? get a small battery with 30+ miles storage and a smaller solar plant, and know you can never charge more than 30 miles a day from it. Want to go on a 300 mile trip? no problem! just don't drive for 10 days and you'll be all charged up.
Unless you are counting on the grid to make up the difference.
