The power delivered by full sunlight is a bit more than 1 kW/m^2 and good solar panels might be 20% efficient. Illuminating 2 square meters of solar panels will add energy at a rate of 400 W at best. It's not nothing, but a typical power draw rolling down the road is ten times that. Put another way, over 8 hours that would work out to 3.2 kWh, which even on my Volt would support maybe 10 miles' driving.
