Batteries exist. Solar panels add weight and design constraints. Why is this a thing? What am I missing?
To the 95% of people without the inclination or knowledge to check the figures, this looks great! It's a car with zero fuel costs, it's EV charging for people who don't have off-street parking, it's a fix for EVs sitting in workplace car parks at times of peak solar output, and it's most of the benefits of covering car parks in solar panels.
That's over-optimistic and you will probably only get that in a small handful of places in the world like the southwestern US or the Middle East and even then only for part of the year.
The hot, sunny, never-cloudy parts of the world also tend to be the ones where driving long distances is most necessary.
Also temperature doesn’t matter too much. You just need sun. I bet it’s enough for most of California year round with minor exceptions that you need to use infrastructure charging.
10 miles/kWh is also insanely efficient, unbelievably so (well over 2x your average EV), and I don’t see where they back that claim up.
That’s one reason electric cars are a bit of a luxury item right now.
I don’t know if it’s theoretically possible to do what they want to do at some point - I don’t know if enough energy is present in the sunlight that falls on the space available on a normal car to power something that meets what the average person would consider their mobility needs - but I just can’t see it with the current state of the art, unless I’ve missed some big shifts in the last few years.
I’d love to be wrong, I prefer to be an optimist, but my inner engineer is just sadly shaking his head no.
It's possible to make a sedan sized car that can be power positive at highway speeds in summer; even with modern safety and features. It's the rest of the year...
The economics of that are interesting. Launch just makes cars. They don't take the market risk of having to sell them to consumers.
As for Aptera, "We are committed to commencing production and delivery as soon as possible. However, the exact timing remains uncertain and is dependent on several key factors..." So it's a Kickstarter for cars. At this point you have to ask whether the product is the car or the next financing round.
Also, it may have too much China content to be sold in the US. They may have to pay off Trump to get past that.
This really doesn’t answer any questions. $44 million (and worthless paper stock warrants) is also immensely low for new vehicle tooling as a whole.
(I'll point out that an article about Slate's frugality[1] still shows some massive costs involved here. They scored a $200 million assembly line component originally from GM for $12 million. Uh, if that kind of seven/eight-figure investment is required for a single component of an assembly line, how far does this $44 million go for Aptera?)

An old neighbor of mine had a Prius with a factory-installed small solar panel, definitely 50W or less, that IIRC was connected to the 12V battery. So one of the benefits would be in counteracting draw from various always-on computers in modern vehicles.
I guess it’s a nice option to have in the market but if what you’re going for is minimal carbon emissions impact it would be best to put those solar panels on house roof I think.
To make it work when you live in a place where you park on the street and can't run wires to the car?
And as a bonus it will help with the obesity problem plaguing this planet which kills thousands yearly.
I use an ebike as primary transportation 365 days a year in Vermont, and you'd be surprised how infrequently you have a day that is actually miserable to be out on a bike, even in a place with very cold winters and a lot of rain. By dressing properly (gloves/scarf when it's cold, rain jacket if the weather is not cooperating), you can eliminate 95% of the annoyances. Something I've learned as a year round cyclist is that most of the rain you experience from inside a car is actually not that heavy when you're out in it. There are maybe 10 days a year where I just have to suck it up (below 0F, heavy rain), and then I usually just skip a trip, take the bus if I can, or deal with it. I get stuck biking in real rain maybe 3x a year, and tbh I think it's probably good for people to encounter occasional friction like that.
And so taking on all of the disadvantages of depreciation, insurance, traffic, inspections, parking, gas prices, parking bans, worrying if that car alarm in the middle of the night is mine, is actually a much worse deal to me than putting up with a few uncomfortable trips per year.
Relatively cheap, can be charged with a regular 230V socket, tops out at 45kmph. Not as compact as a bike for obvious reasons, but still a substantially smaller footprint than any modern car - and comes with proper weather protection.
And now they won't to power the entire car with energy from solar cells on the car? I have my doubts.
Also, enough energy for some range ≠ enough power to drive constantly.
This finally answers questions that have hounded the company for years about their plan for scaling and fulfilling the thousands of reservations.
