Did you factor in battery life/degradation for your solar and vehicle capacity/costs over ten years?
Yes. If you want that and other details it's in a post from May at https://freerepublic.com/focus/news/4060059/posts?page=22#22. It's not for everybody. But it's good if you live in the southern half of the U.S., plan to be there 10 years, have a roof that'll last a while (I have a metal roof) so you don't have to move your solar panels when you replace a 10-year shingle roof (if your panels are on your roof).
