I know the range extension would be negligible, but since most people will have an electric car sitting in daylight for a huge number of hours every week, and is has inbuilt batteries and charging regulators, wouldn't it just make sense to have PV cells built into the bodywork? They would add almost no weight if done properly, and would reduce the burden on the grid. Of course they would have to be done both tastefully and with the ability to recycle.

If you live just a few km from work and park outside there all day, it could even be a significant percentage. And those who live close to work would likely be the first adopters of electric vehicles.
