This could be the start of the biggest game changer to extend EV range

If this new technology truly works, as promised, this could be part of the solution to range anxiety.

Having this coating on your rig could help somewhat with battery charging and range.

But to really work well enough for overlanding it would have to be greatly improved in output or coupled with something else like flexible solar panels on the roof of your rig.

Still, the concept holds promised and is something to keep an eye on.


“Electric vehicle charging and infrastructure are two major obstacles to EV adoption on a mass scale, but Mercedes-Benz may have a solution in the form of solar paint. In an effort to increase efficiency, the German automaker has created a new solar coating that could cover future electric models. Mercedes-Benz’s solar coating could revolutionize EV charging, making it more convenient to own an EV or PHEV.”

Mercedes-Benz’s solar coating can cover the entire body of the car as opposed to just the roof or sides. The coating weighs in at just 50 grams per square meter and measures just five micrometers thick. It can also be applied to any surface, including panel creases and curved fenders.

According to Mercedes engineers, the solar paint currently operates at 20% efficiency, the same efficiency as the solar cells that are currently used on vehicles. In addition to being more flexible than solar panels, solar paint is always active and can charge an EV battery at all times, provided there’s sunlight.

Currently, it could generate enough energy to add 34 miles to an EV per day in sunny areas.”

🤔 maybe with the larger surface area of a big sprinter van, you could perhaps double or triple the increase in this additional range. That extra mileage might be enough to make you feel safe that when you hit the point where you need to turn around because the batteries are going low, that extra charge that’s been added. Will be enough to get you back home.

If the manufacturer does not include thorough testing protocol and data, then I figure this is Pop Sci level BS (ie marketing).

Solar cells on cars have been a thing for a long time, and they are mostly a gimmick... due to the amount of energy gained not amounting to much. This paint might be a cheaper gimmick, which could be nice. But not a game changer. Even the Aptera which is a light and hyper efficient design, doesn't get much from it's solar cells.

A Mercedes electric minivan consumes ~500Wh/mile. Say, 1,000 for a loaded Sprinter? Even if you had ideal conditions, full sun, nothing on your rig blocking the sun... maybe you'd collect 10kWh per day? Which would allow you to go 10 miles. And this is assuming that you don't need any of that electrical energy to run all the other systems on your rig.

I’d see it as able to run the other things and recharge a bit if I was on a three or 5 day hike away from the van plus a recharge if it sat in the AZ sun for the weeks between trips? Just an added boost not base power.

^If you are parked in the sun for long periods, then yes... it could be significant. I think the primary benefit would be a cheap and simple way to get a lot of solar energy for running appliances. That would be quite nice for non-EV vehicles as well. Provided that it actually is cheap and durable, etc.

I've thought about getting a EV moto (or ebike) and making a small single wheel pop up trailer that I could sleep in. This would be for long term traveling, living, exploring. The top of the trailer would have solar, but I'd need to carry light solar panels and park for days to recharge... or if on actual roads, I may be able to plug in. If I was younger I think it would be a fun way to live.

This might be really cool as house/roof paint for those who live in sunny, equatorial zones....if it's affordable.
