Why don't electric car manufacurers put solar panels on the car roofs? - eviltoast

Honestly it seems like a no-brainer to me to put a solar panel on the roof of electric cars to increase their action radius, so I figured there’s probably one or more good reasons why they don’t.

Also, I acknowledge that a quick google could answer the question, but with the current state of google I don’t want to read AI bullshit. I want an actual answer, and I bet there will be some engineers eager to explain the issues.

    The Fisker Ocean has solar panels on its roof. It can add 4 or 5 miles a day if fully exposed to the sun.

    Not enough to matter. It’s a gimmick.

    If you don’t have an EV, you may think that EV owners are worried about range, and they’d welcome any increase. I have not found this to be true.

    It’s more like having a car that starts every day with a full tank. You’re never going to burn through that in a single day. Pretty soon you don’t care about range, efficiency, or pay much attention to the battery meter. It only matters if you’re on a road trip, which for me is a couple times a year.

    I would not want to give up a nice full-roof sunroof for a few extra miles a day.

      The newest revision of the prius has an option for rooftop solar. The break even point is relatively long, in the 5-8 year time frame iirc. The energy generation isn’t massive; at 185w it won’t substantially extend the range something like 5 miles per day.

      For an extra miles a day… if you park in the full sun all day every day. Garage? 0. Driveway? Probably shadow half a day.

        if i park in the shade, and therefore don’t have to turn on the ac as soon as I get in, I think that would be about the same, savings wise.

      Right. Unless you live in US and have relatives you regularly visit in a different city in the same state only 400km away.

      I mean I still don’t care about solar panels on my roof and I’m much happier with a moon roof on my PHEV. Nearly 80km of electric range means I’m driving an electric car 99% of the time and have convenience of 5 minute fill ups when I go further.
