FAQ:

Q: What vehicles use solar panels?

A: Some vehicles, such as a high-end version of the Nissan Leaf, have used solar panels on top of the car to power certain functions, such as the computer system.

Q: Why don’t electric cars have solar panels?

A: Most electric cars don’t have solar panels because it’s not worth the compromises. There isn’t enough sunlight falling to power the kind of car that most people want, able to climb hills and accelerate effortlessly away from traffic lights while carrying a load of passengers and luggage.

Q: How much does a solar powered car cost?

A: The nationwide average for the cost of solar equipment is $4/watt. You’ll also need two Tesla Powerwall 7-kWh batteries for charging the car, which cost $3,000 each plus $1,000 for installation. So we’ll multiply each system size by $4,000 and add $7,000. But then there’s incentives, which vary all over the country.

Q: Can solar panels charge an electric car?

A: To efficiently charge an electric vehicle using solar panels, you will also have to install a home charging unit and a PV inverter unit that converts the solar energy into DC current for the vehicle. There are several systems available for purchase already. The costs aren’t small, though.
