    True, but my understanding is the amount of solar energy that hits an area the size of a car multiplies by the max possible solar energy conversion is still far below what’s needed to power a car. Sure, you can continue to charge it while parked, which is cool. However, you could also put cheaper non-custom panels on a building and then plug your non-solar electric car into it to charge while parked, and the building panels will have significantly better solar exposure and be cheaper per panel.

    If your goal is making something effective that reduces carbon output, an EV and solar on a building is much better. If you’re creating junk to get VC funding, this is what it looks like. If this comes to market at all, it’s not going to make any waves, except maybe for how impractical it is.

      Oh, I agree with you there (well, not in the tech itself, why not both, have panels on buildings and on some cars – plenty of people drive only a few thousands of kilometres/miles per year & still need a car).

      I’m just saying that as engineer I would start testing them separately, in lab conditions first to get the basics & correct obvious initial faults, then separately outside.
      As management I however would insist that engineer has to find a way to glue whatever solar panels they can find to the prototype if there is gonna be a press release.

      I didn’t read much what they are doing/going for tho, so can’t say much about that.

        Why not both is because most people don’t have unlimited money. It’s about opportunity cost. It’d be better to buy a cheaper EV and better rooftop solar than and expensive EV that has mediocre solar charging.

        For sure they should test them separately if they’re doing this though, or at least not use custom ones for the prototype. You can buy small panels for a reasonably good price, and they could just stick those on the car for a proof of concept. The problem with this is it’d prove that the amount of power required is way more than is going to be generated. If they can talk about concepts then then people can still wonder “what if…” If they actually implement it then it makes it obvious there’s no reasonable path to a good market and they lose FC funding.

      I could see a market for a small electric camper van (Like actual small van sized like the old VW vans) with a solar roof. For regular camping you would always have electric to charge your phone and if you wanted to tour around a bit you could probably stay at each location for 2/3 days and gain enough charge to make it to the next one (at least in summer)

        You can get teardrops with solar panels, but I haven’t looked into electric RVs.

        For sure. I’ve always lived an idea like that. You can buy portable solar panels you can throw up on your roof when parked though, or place them elsewhere, so I don’t know if it’s required. It’s a concept I could see actually working though. Not this.
