A SOLAR POWERED AUTO

Does anyone have other examples of REAL autos that are solar powered? I have no reliable information about this subject...Some questions I have is how long does this battery (at 3KW) require to really fully charge? Can it charge from a street light or must it have the sun?

California-based Solar Electrical Vehicles (SEV) has created an option for the Toyota Prius electric hybrid.
 
This option consists in a solar-panel made from high efficiency mono-crystalline photovoltaic cells, with modules rated at 200-300 watts. The power obtained is used to charge the 3kW secondary battery that can be used to drive the vehicle up to 20 miles per day on electric power.
With fuel economy improved by around 29%(this depends on the driving style you have) owners could recuperate most of the $2000-$4000 cost of installing the system within 2 to 3 years. Performance will be improved further with the addition of higher-capacity batteries that currently are in development, potentially adding another 10 miles of electric-only drive. http://4wheelsblog.com/prototypes/solar-power-option-for-toyota-prius
