This seems... OK? Solar PV panels have come down in price a lot and so the main challenge is installation. You need to manufacture mounts, fit them to a suitable surface and then hook them up so as to deliver the power at a time and place where it can be used. Most cars are outside all day long and electric cars have a big battery sitting there, ready to accept charge. Car manufacturers are the experts at mass-manufacturing so this is probably the cheapest and lowest impact way to install and use some solar electricity generation. If your vision of the future includes solar PV covering every external, manufactured surface then this is the place to start. Of course this doesn't do much for the range of the vehicle in question; building and operating cars is incredibly resource intensive and is only ameliorated by making them hybrid or electric. These panels are a concrete reminder that we need to reduce that usage to soften the damage we're doing to the environment.
