I still say there is nothing at all economical about several thousand dollars of solar cells sitting on a car that *are-only -used* for the 5% of the day it is actually propelling the car under good solar illumination.
So the goal of solar is still a 95% issue of charging, not a 5% issue of direct propulsion. To think otherwise and try to force the solar panels to only have value during 5% of the day it is propulsing in full sun does not make much economical sense. But maybe we are in violent agreement... and I am just misunderstanding your approach.

Bob Said:The practical application of solar panels on a car are not for propulsionbut for charging while parked. The typical car sits at work under the sun for 8 hours a day. With just 500W worth of solar panels during an 8 hour day, replenishes possibly 10 miles of range. Usually plenty enough to get back home for the small EV and commuting. This is true for the typical conversion or OEM EV. However as you lower the weight and raise the quantity of panels you will find the solar vehicle more useful. In other words you are thinking in an old engineering way. We need to think lighter. Like an RV that is 22 feet long 8 feet wide. About as light as a Nissan Leaf. You say this is impossible uuuh... They made them in the 60's and 70's. Called the Ultravan they were ahead of their time. Getting 18mpg with a Corvair motor. They were constructed like an airplane fuselage out of aluminum. Many are still on the road. A few used ones go up for sale from time to time. A Leaf drive train in one would be very useful. I am sure you could get close to 4kw of solar panels on one.
