The Cybertruck’s solar tonneau is certainly a key feature for any future buyer, given the fact that it would give the possibility of semi-total independence from the grid and charging stations; obviously depending on the number of miles a day driven. With 15 miles of added solar range, and with the option of adding another 25 miles (totaling 40 miles on 100% solar) by adding extra foldable solar wings, the feature is certainly attractive.
