    There’s something that people really fail to grasp with solar, and that’s the fact there is bugger all energy in the sun, and you need a huge surface area to get any meaningful energy.

    A home solar array often takes up a significant chunk of the roof area, and the amount of surface area a car typically has means that even perfectly efficient solar panels wouldn’t collect enough energy to significantly contribute to the vehicle’s range.

    There’s a good reason why vehicle manufacturers don’t bother adding them.

      There is good amount of energy in the sunshine. The output of solar arrays struggle to make big power out of small surface areas because we haven’t figured out how to get more than 20% of the power that hits the panel. If they do get 20% or more, it’s been with very expensive and fragile panels.

      Yes, but with a light and efficient vehicle, along with enough area covered in solar, it should be able to get you about 15 miles of free travel when left out on a sunny day. It has a battery. It isn’t just running on sunshine and lollipops.

        15 miles a day under ideal conditions isn’t really a significant amount, most EVs could run for multiple weeks without being charged under those conditions.

          I currently have an ICE car, and with how much I use it, 15 miles a day getting added to the battery on average would probably cover most of my usage. And you can still plug it in for longer trips. You’re not forced to rely on solar alone.

      Solar panels are also added weight, which reduces range. Any way you look at it, it makes more sense to have the solar panels at a base location you go back to.

      I guess an RV, or a camp trailer, makes sense to have panels on it, but that’s about it

        There’s also things like Sentinel mode on Teslas that use power.

        My main gripe is people think a solar car will never need to be charged, or only on trips, and that’s just not the case.
