With Hyundai releasing a car a few years back with solar panels on top, I am curious if this is a modification people are doing to their cars that do not have them.
Have you heard of any sort of solar panel kit or some sort of fixture for a car to allow solar energy be it for recharging an EV or other uses such as camping?
You can use something like this for your car:
Though, as he mentions, it would take days to fully charge your car using one of these but it is good to give you a boost. If it is sunny for several days, it could cut your next charging session by 10% or so.
