You're about an order of magnitude off. 2.4 kWh/mi is a total range of 40 mi for a 100kWh battery. Very good panels are 24%. A reasonable capacity factor for something car shaped is 10% So about 20 miles/day in an open parking spot. More realistically there's probably a lot of spaces you couldn't fit a panel on, so maybe 10-15mi/day reliably in most places. Enough to significantly reduce charging for a moderate commute and errand runner or eliminate it during summer. I'd be a bit sceptical of their claims of reaching similar with polymer cells with such a boxy car though.
