Based on the numbers quoted on the site, 30 km of range is equivalent to what you'd get if all of the solar cells got 4 hours of direct illumination. On the one hand, they can't all be in direct sunlight at the same time, given the car's geometry. On the other hand, many locations get more than 4 sun-hours per day on a horizontal surface[1], especially in summer. So it doesn't seem too implausible. And if your commute is 30km per day, then even if you don't get enough sunlight to reliably charge the battery every day, you still have more than a week of buffer in your battery.
