There's something that people really fail to grasp with solar, and that's the fact there is bugger all energy in the sun, and you need a huge surface area to get any meaningful energy.
A home solar array often takes up a significant chunk of the roof area, and the amount of surface area a car typically has means that even perfectly efficient solar panels wouldn't collect enough energy to significantly contribute to the vehicle's range.
There's a good reason why vehicle manufacturers don't bother adding them.
Their tech isn't just the solar, they've optimized the car solely for efficiency. They claim their car can get 10 mi/kwh, so with 700W of solar panels they can get up to 40 miles of charge per day with just the solar. By contrast, the solar panels that are available on the new Prius get 4 miles of charge per day.
Now that their production-intent vehicles are just starting to be built up, I'm eagerly awaiting their actual test data that hopefully verifies their claims on efficiency, range, crash safety, etc. but we'll see ๐ค I really hope they succeed.
Yes, the aerodynamics + solar panels is what makes this vehicle enticing, not just the solar panels alone.
