Well, that’s 50 miles on a perfect day. On an average British day outside of the 3-4 extremely good weeks we can generally rely on each summer though, I’m unsure how it would translate?
Not knocking the technology, it’s still a good thing and part of the mix, I just wouldn’t personally get my hopes up about a solar-only car (unless as discussed above we’re talking panels all over a house roof with that specific aim in mind).
