Solar brushless RC car

[Maciolus]

I am preparing for solar rc car build. My aim is to build light and efficient setup.

General idea is to use 10 3.35x3.35 inch 1.1W solar panels, Mamba Micro Pro ESC and tiny outrunner (9/16 inch diameter). Frame will be made of laser cut balsa wood. Its gonna have only 3 wheels. Estimated top speed will be about 16mph.

The third wheel will be outrunner itself with rubber o-rings working as a tire. Moreover outruner will be attached directly to a micro servo for steering.

I wonder how big capacitor do I need for such a project?

Thanks for any help :)
