I wonder how many km of travel the panels waste from each charge.

This hoax has been tried before and the panels add more weight and air
resistance to the inefficiency than ever recovered from the PV charge in the
parking lot on a normal drive to work and back. You may notice than no other
electric or hybrid vehicles, from major manufacturers, have PV panels on
them. Some day the efficiencies may break the 14%  barrier and it may be
possible.

As to efficiency, normal c-Si panels in the market now are beyond 14.5%,
and the highest is Sunpower's 20% series.

Much depends on the 19 y.o.

 Even if these panels can actually generate 20% efficiency they can never
produce enough energy to warrant the drag added to a vehicle.

Universities around the world have been competing with solar vehicles for
decades and even with huge wings and wheel covers covered in PV panels, with
their 18" high low resistance models, the success is not good enough for
actual usage in the commercial market.

Without doing some hypothetical calculations I still suspect a few days
charge wouldn't get you more than a few km as published by major electric
car manufacturers, in the past.
