Can you create a solar kit which feeds power to the traction battery? Even 300watt hours worth of panels would be quite useful.

What are watt hours of panels?

Some people might just call it 300 watts.

Which would be the correct units when talking about solar system sizes or power output.

Typical day might yield 5x rated watts as watt hours. So maybe you add 4 miles per day in ideal conditions. Not going to be worth it as the aerodynamics would probably kill more than the gain unless the panels were custom contoured to the vehicle.

Exactly, it needs to be built into the roof and hood. Guessing you could fashion 5-600 watts into the 2 surface with inexpensive panels. 10 miles a day would be very helpful.

I started https://mynissanleaf.com/viewtopic.php?t=6316 long ago to talk about solar panels on the roof of a car.

I already tested it.
Unless some one can come up with a way to very efficiently boost 10 to say 48v up to 383ish volts and activate the obc there isn't much point.
Boosting the 12v system with external power does almost nothing. It would be a lot of work to get maybe a 1% boost in range.
In park, no external lights, no heat or AC, pumping 14.6v into the battery at 12 amps it would reduce traction battery draw less than a half amp.
A grille block, brake pad drag reduction clips, reversed mud flaps even if your car didn't have mud flaps and bought them from a dealer to butcher, pizza pan style hub caps, would be cheaper and more effective.

The only way boosting the 12v system could be noticed is if you drove the car a lot during the day, city driving and could cover most of your 12v heatpump blower and condenser fan load with solar.
