EDIT: That's 3.27W/cell, which SunPower cells do provide. I counted the cells:
Roof: 114
Hood: 45
Dashboard: 24
Driver Front Door: 33
Driver Rear Door: 21
Driver Rear Panel: 21
Passenger Front Door: 33
Passenger Rear Door: 21
Passenger Rear Panel: 21
??? unknown location: 16
-------------------------
Total: 349
So only, 52% of the cells will ever have the chance of being positioned correctly. Even still, the angle of the roof cells are curved, so half of those will not be in good positions when the hood is angled directly at the sun.
That leaves you with 126 cells that might be positioned correctly, which means a real world capacity of 413 W, which will result in a max range of 23 km (EVs get ~7km/kWh). The 30km range is extremely ideal, and real world is likely closer to 10-20km from 8 hours of solar. That's ~2km per hour of sunlight.
Anyway, parking the panels directly in the sun at the ideal angle for 8 hours will be pretty impossible for most people. However, it might have a niche use case for remote research stations or cabins?
Unfortunately, the marketing on this makes it seem like this would be good for urban users, so the team appears to be heavily misleading backers (e.g. scam). Cities are extremely bad for solar cars (all the tall buildings make a lot of shade).
