A solar kit can be installed on virtually any type of car, but it is easiest to convert an electric vehicle to run on solar power. If you intend to use solar panels to power a standard gas-powered car, this will be more complicated.
You can't 'run' an EV on solar panels on the roof unless you've got a HUGE roof. There's nowhere near enough room to mount enough panels to move the car
Even the Fisker Karma which came from the factory with an optional $5K 'solar roof' just used the power from the roof to run fans to cool the inside of the car a bit so as to lessen the need for the car's air conditioning system at start-up and that saved a few hundred yards of range
"Put solar panels on the roof" is an idea that surfaces here from time to time, almost always from a newbie who doesn't yet understand the physics involved in what it takes to power an EV. You need 3 or 4Kw per mile. Two 100 watt solar panels on the roof of your car would be doing very well if they could make 750 watt hours per day, so if the car sat in optimal sun for 4 or 5 days, you could then drive it for about a mile . . . . but the added wind resistance of a home made solar installation could 'cost' you about that much energy due to added wind resistance when driving, so likely you'd gain next to nothing
