Okay downvoters, let's run the numbers. Suppose you have about 1 square meter of solar cells on the roof of your car. From Wikipedia, a typical solar PV installation in the US or Europe gets 1kWh/sqm/day (depending on latitude, of course). How far will 1kWh take you? Let's see, gasoline contains about 37 kWh/gal (US), which at 40mpg is a little over 1 mile/kWh. So if your electricity-to-fuel conversion process is 50% efficient, you'll get about half a mile on a day's charge. |
