No way you will get 10% better FE by eliminating the electrical load.
No way you will get the full 100W by placing the panel on your trunk.
The 100W rating assumes the panel is facing directly at the sun, and it's a bright and cloud free day.
If a 100W panel is added to the car, you will want it to switch off with the ignition, otherwise you will fry your battery when the car is parked and not loading the solar panel.
