Why aren't solar cars everywhere?

Electric vehicles are here to stay, but charging times and range are still major turnoffs for many buyers. So why not just slap solar panels on the car and drive indefinitely with zero fuel cost? A handful of solar cars are available for pre-order now, but how realistic is the tech? Can solar power provide enough power to extend range and cut charging time?

[@MRBlack-Ravn]

@@DWPlanetA Solar powered cars are great for many reasons! First of all, they are environmentally friendly because they do not emit harmful gases. They therefore help reduce air pollution and chemicals. In addition, they are also cost-saving, because you do not have to buy fuel. And of course it is also a great way to use sustainable energy sources. 🌞✨

The California net metering 3 doesn't make sense (especially for small installs). Aptera bypasses permits / electricians and works for those that are renters or in condos. That said I'd happily buy an Aptera without solar because I'm in bc and our power is cheap and reliable (hydro).

[@KarpKomet]

Agree overall but i came around to solar on cars despite that as a concept a couple of years ago. Trickle charging while moving/stuck in traffic/away from charging cables is a cool trick, and charging infrastructure is expensive. If everyone could plug in at work with level 2 charging great, but we aren't even close to that or will be in the near future. So on a City or Country scale, having in theory every second car or so top up some EV range would for sure take a load off your charging infrastructure. Things like 15 minute quick charging only partially help with that, solar could still be one part of the solution taking some of the burden off $$$$ expensive things like public level 2-3 chargers.

[@fulconandroadcone9488]

@@KarpKomet how much range do you get with 3kW charging? 8h at work + 8h at home during sleep, that is 16h * 3, that is 48kWh just a regular power outlet for each car and do you really need close to 50kWh for your regular commute? I would imagine not really, you need fast charging when you don't want to sit and wait for it to charge, you really don't want it when you are sitting around not needing your car for the next 8 or so hours.

Your video was doing fine, but then mis-reported the info on Aptera. That one incident occurred when Aptera demoed the prototype/show EV without hooking up the onboard cooling to the motors. It was a mistake, and you should really do a follow-up video with Aptera to be fair. Aptera is currently in the process of building a handful of production intent models, with all systems working as they will on the production model in 2024.

[@aussieideasman8498]

They didn't misreport. The stop actually happened, and they didn't say why. It could be you who misreports because there is no evidence that lame excuse you gave was true. They lie at AM. Here are some more details, but before I do, don't forget it overheated and stopped for Nikki at TE, and the excuse was sillier than the first: Gamma was built almost a year ago and within a couple of weeks was whisked away to Italy. It was seven months later that it returned and had that incident. Steve Fambro took the fall by saying he had forgotten to put the hoses on when it was made. That's a long time to be forgetful, and then there are the engineers who forgot and never gave it a second thought for so long. There were videos that showed that the hoses were likely there, and just prior to returning from Italy they did a con job of a wind tunnel test that showed they weren't there. One astute observer claimed they removed them to cheat on the test (along with taping up the windshield gap and lowering the suspension) and forgot to put them back for just a couple of weeks, but even that is almost as much of a stretch in plausablility. Regardless - the huge weight difference of Aptera; the less area of cells; the biigger tyre footprint; and the cost of solar technology being way beyond what Aptera has raised should be enough to convince you that Aptera has no chance. Better ask for your money back while you still can.

NBC drove the prototype that didn't have the cooling system connected to the motors. Though a misstep on their part, the company made it clear after what the issue was. Also several other KZbinr's and others have driven their different prototypes. I see you like to use the car in all the b-roll shots, but then fail to do almost any research on the company that's the most open and honest about their development.

A car that removes the need for gas stations, and you can charge on a regular outlet at home?!? Keep dismissing them, and you'll be wishing you hadn't later on.

True, I think big car manufacturers should just continue offering as an option. A bit of added range will still help even just added 4-8 kms per day. That still worth like going to shops or work that aren't close at home. That's free energy. For buses, trailers and boats. I think this will shine better due to bigger surface area and far more efficient due to theu can carry more load for a single vehicle. Trains? Well they help but really uncessary. Electric trains already run by the external power source which is more efficient, and solar panels can be simply installed on each station and depot. Trains already most efficient mode of transport that somehow many in North America region seems to forget. Solar can improve it for sure though.

Charging an Aptera is accomplished by 1) a Tesla charging station, 2) standard household plugin, and 3) solar panels. I live in a cloud-dominant part of the country and even though I'm ordering the full solar panel setup, I am not depending on it. I'm getting the 600 mile version and most likely plug into my apartment's outside receptacle. I imagine I'll charge at Tesla stations only on long summer trips and hope the solar offers some assistance. In short, I don't consider Aptera to be a solar vehicle. People who live in a sunny climate and use the vehicle for commuting could consider it a solar vehicle. They'll need to discover the ideal parking positions. If they don't live up to the hype then they will need to revert to the plugin options. If you don't like or want an EV, then don't get one. EVs aren't going to save the planet, but they aren't going to ruin it either. I can't stop the burning of coal for example but I can stop driving a vehicle that emits toxic particles into air that my friends and family inhale. I don't follow/read many automotive publications but I would wager few, if any, point out that ICE vehicles emit poison and offer solutions to stop it. That's because they don't have solutions.

In comparison to that the upfront costs for building an integrated solar car are enourmous and as we have seen time and time again, investors aren't willing to pay these prices.

If all external parking spots had a canopy with solar panels and charger allowing only to get the energy from the panels, not from the grid, this might be worth. But carrying the panels with you on the car is not the best thing ever. Any scratch and your production goes down substantially.

The 4 km/ day stat for solar self charging is not too bad considering how many two car families there are out there with one or both sitting parked all the time. If they could get that to 8-10 km/day on solar that would be really good. I am car free, but there are many (including my ex) whose commute is relatively short (say 7 km each way in her case) and the car is driven because the public transit connections just don’t work competitively (say 8 minute drive vs 55 by bus). In my case, I switch to transit from bike commute during the winter and I’m living in a great, central area, close to work, but can walk in almost same time as my transit commute.

[@jonevansauthor]

That's a fundamental misunderstanding about solar cars that they didn't clear up when talking to the solar car engineers who are working on cutting edge competition and R&D. The idea is NOT to power your entire possible driving range with the solar panel on your car. What this does for you is give you enough range to get to a charger, if you don't have home charging. It probably gives you enough to get to work, park, and charge up enough to get home. If it does not, you live too far from work. No-one at Sonos or Aptera or Lightyear was expecting people to wait for their car to reach 100%, drive it for 200 miles, then leave it for ten days to recharge fully. Now, don't get me wrong, there's all sorts of reasons it's pretty niche as an idea but it is only intended to give you enough per day to be useful. Bearing in mind most cars are only driven tiny ranges, that's an achievable future. Still doesn't mean it's more practical than other options (e.g. portable battery you pull from the vehicle, which is widely available and could carry the same 'range' even on larger vehicles).

[@GamerplayerWT]

“The roof is wasted space.” Not really. The roof is part of the structural integrity of the car. Adding solar panels adds weight which partially eliminates their potential. What we need is a radical new innovation in solar technology. Something like spray on paint that can harness solar power.

[@tHebUm18]

Neat in theory, but outside special cases like topping the back of a semi trailer with panels or an RV roof I don't think it'll ever add up to have solar panels on vehicles. Certainly not at current solar costs even far cheaper than they used to be, maybe ever--the energy gained is just so trivially small. Sounds like the mentioned studies didn't even account for the car getting dirty when parked outside to soak up that solar energy--might be a net negative environmentally just in your increased need to get carwashes, never mind the negative harmful effects to paint and general exposure parking outside vs in a garage and the fact that almost no one can park somewhere that'd be in direct sun all day every day (well, during daylight hours). I think the hypothetical projections are vastly better than anyone could ever achieve real world.

As much as I love the idea, it doesn't take a lot of engineering to understand that even if solar panels were 100% efficient, it's currently impossible to have a mass production vehicle running purely on solar given the surface area vs weight and marketable (comfortable, AC, 80mph minimum, etc etc)

Starting a new car company is hard. And it might be too soon for mostly solar powered mainstream cars. But in general solar on cars will indeed be a thing in the not too distant future. Legacy automakers are already offering or planning solar on the roofs of some vehicles. Range anxiety, charging wait times during rush hour, things like perovskite PV and solar glass on the way, ever stricter emission laws. I could see 3-5 km a day from the sun(when its out) becoming worth the hassle real quick. Interesting about the inverter controller cost issues but If you don't go crazy trying to squeeze every watt or slap a solar panel on every square inch and stick to a rear bed or roof, the cost and durability issues can be overcome.

[@fulconandroadcone9488]

And how much range would you get if you put the same amount of money to put panels on your roof? This system adds complexity, cost for a 5km range a day at best? If you put them on your roof you will have far better sun angle and it will be constant. Then plug your car at the destination and pay utility company for ship electricity from you home to your work place, or store, or where ever to charge your car away from home. And when you really thing about 5km added range with about 25% efficient panels, lets even say it is 20%, in that case you are looking at about 25km added range a day if we ever hit 100%. That is worthless for long trips, 25km on 600km trip is a couple of minutes of charging at best these days. But I'm very much in favor of solar powered vehicles, and we do have them, and they today have, what you call it infinite range. Electric trains utilize the power of national, or in some cases continent wide grids.

This will allow to recharge my EV almost exclusively from the sun 6 months per year. 50k eur seems a lot, but it's actually about 10 years of fuel for an ICE car. So, it's paid off between 10 to 15 years. I am doing this investment for another reason : avoid company taxes on profit and see my company money disappear in taxes.

Any true experienced engineer of any field can agree! Any amazing project will never start perfectly. Great steps forward guys!

I think the only way is if they made extendable solar panel cells

This is the future of vehicles.

Guys, here's a better idea - make replacement panels and system integration kits for curret HEVs and EVs. Start with a prius or a leaf(zoe).

Because the established companies want them to get out of the competiton.

Love DW but seriously, you guys kinda did Aptera dirty on this one. You should cover them properly and you'll see just how close we are to the everyday solar car being on the roads everywhere.
