I’m glad I searched the forum first and found this.
An additional capacity of 1000W of solar is great and I look forward to the spec on how many additional amps/volts the solar charge controller can handle and the configurations that can be used (series/parrallel panels).
The practicality of this for road tripping is not ideal. You would need to lug (4)- 250w std polychrystaline panels (typically 65″x40″) to get that capacity. Monochrystaline flexible is an option, but those produce less power, requiring more panels and they are more expensive.
Maybe this is a boon for those with solar at home, with the assumpion that direct DC charging from solar will be more efficient? You could dedicate a section of the array for the vehicle for direct DC charging. Unless it’s much mor efficienct to DC charge via solar directly (and that will depend directly on the charge controller Aptera decides to use), most will plug in to an AC outlet and chug…

Tesla will not release a “Model 2”, or whatever they decide to call it, for at least another 3-5 years.
I know their mission is to accelerate to sustainable energy, but their goal is to accelerate production right now and that is with the model Y and 3 in two new Giga Factories (Berlin and Austin).
In 5 years Tesla will have completely ramped out manufactoring of it’s own battery cells (4680) in all of their factories allowing for production of the low cost alternative.
Adding another vehicle to a lineup that already isn’t producing the much hyped Cyber Truck and the Tesla Semi (Both of which were supposed to be in production FY 2021) would steal battery resources from 3 and Y in their ramp up in the new factories.

I opted for the 400 mile range battery for the following reasons:
– This will be a daily commuter, with an average round trip of 60 miles. (60mi x 5 = 300 mi).
– I live in “The Sunshine State” Florida. I expect at min 10-20 mi of solar charging daily to suppement range (Full Solar Package Option).
– The pack is smaller, less wieght, so my thoughts are best power to wieght ratio (tri motor configuration for me).
All said…we really don’t know what the final product will achieve, but if they can get close to their stated goals of efficiency and price point, then all is well.

My configuration is $40k.
I honestly DO NOT expect that this price is set in stone. I do expect it to be close within a margin of 10% however, because if not, something isn’t jiving with their fundamentals.

No. I expect android auto.

Personally, I don’t care for any credit, let alone a lopsided credit that favors a particular manufacturer or product because of how or who put it together.
That said, you use your funds as you see fit. There are always options to be had, if you see value in a product you buy it. If you don’t, you leave it on the shelf. Apple I-phones are very expensive, but apparently they sell like crazy because they are very good…whereas Google phones are not as good, so they don’t. People will pay for services and functionality even if it means paying more.

Here’s the deal.
Early adopters need to be patient. A wise man said, “Prototyping is easy, production is hell.” Aptera will undoubtably have issues with production, everyone does. Getting production to scale, is a whole different story. I would guess that if they produce 200 vehicles in thier first year (hopefully mid to late 2022), that would be a major victory.
They need to crawl first, then walk before they can start running.

Ok, so the video is cool…
…However, nothing really new here. Another ‘test drive’ with a few more details on their design processes of the Beta. It’s October, I would have thought maybe they would be on to Gamma and crash testing.
The comment related to the flexible solar cells as something “you can’t get off the shelf” is a little disingenuine. You can, check this: https://ebay.us/T9ajKP I did a little math and it would take aproximately 210 of these cells to get the 700 Watts of charging. It appears from the image below, that is about correct (I didn’t really get into counting them). Monocrystalyne cells are more efficient than Polycrystalyne, In the case of these Ebay cells, 22% +/- efficient.
Still excited…still have tons of questions…still want to actually see one on the road.

That motor whine…
I know, I know, it’s still an alpha….
MemberAugust 31, 2021 at 5:12 am
Nope. Not a good idea. Weight is always a key factor for sure, but range and charging are always at the top of the list. Range doesn’t seem to be an issue ( per their specs ) but charging is fueling and fueling allows you to range further.
Add to the concept that if they want to use the Super Charging Network, it would be best to get closer to the maximum level of that network.
C’mon guys. This isn’t even a question for a daily commuter. It’s a negative.

Steven, I really appreciate your enthusiasm about Aptera…honestly and truly do…
However, do you know when you will get your vehicle? You’d be paying for the promise of something that hasn’t been made yet or before? Heck, it’s not even approved for use on the road yet.
Slow your roll brother. It’s coming, I have no doubt, but I doubt Aptera can ethically start taking payments for something that isn’t there yet.
MemberMay 19, 2022 at 9:01 am
Well said Ray, I said something very similar. The charge controller will determine the solar array configuration to get that extra 1000 watts in addition to the proposed 750ish watts. Not sure how practical it is to lug panels around, but if the charger is high efficiency then direct DC charging at home might make some sense vs. 1800w standard plug (120v @ 15 amps).

David Maddon, not true. At most you will get 10% of the purchase price. For my configuration as it stands, that about $4k….

Optimistic is what all entrepenuers are sir…that said, being realistic doesn’t sell snow cones to eskimos.

Joshua, your summation related to NDA and patents reminds me of Sandy Munro and his podcast. He has been asked many a question related to Aptera and other companies that he is working with and he quickly will say something to the effect, “ummm, yeah can’t talk about that one…NDA…lets move on”.
MemberSeptember 22, 2021 at 4:44 am
Carl, dry, moist (love that word) heat, doesn’t matter. The fact also that we will be placing our vehicles in direct sunlight with solar thermal gain to gather miles adds to the question. Typically I search for a shaded spot here in NE Florida now to keep the radiant energy from making the cabin unbearable.
I’m very excited about the vehicle. I see it’s potential for my use case, daily commuter.
I think Joshua has a great idea. They should do a focused presentation on the tech they propose with some ‘potential real life use cases’ to address this question. I know I am not the only one.
MemberSeptember 21, 2021 at 2:13 pm
I agree. I do understand that this is IP territory, but it is a huge concern for my location in NE Florida. AC is king here…????
MemberSeptember 21, 2021 at 2:12 pm
LOL…I am not saying that this is the case at all!
MemberSeptember 21, 2021 at 12:38 pm
John, I have no doubt that the engineers have researched this and have a solution. Can we get some information related to this though?
I am not saying it won’t work, I’m not saying they haven’t worked it out, nor am I saying they are dolts. I am saying laminar flow is not ideal for heat gain/dissipation. Turbulent flow is better at this.
I as an early adopter with a low reservation number have questions. I have watched all of the provided information from Aptera, and I like their presentations. It’s getting close to ‘nut’ time though. Rather than a ‘hey they got this’ response, is there someone with actual information related to the systems and how they will perform?
MemberSeptember 21, 2021 at 12:07 pm
Climate, cooling, etc.
If you look at other EVs, there is a multi-junction valve (Tesla octovalve for instance) that diverts cooling and heating respectively to batteries and climate system.
John, I’m not saying that they do not have a plan, have engineered a solution, but it’s a new technology in regards to being applied to the automotive space. As someone who want’s to be an initial adopter, with a low allocation number, I have questions about the systems of the vehicle.
This isn’t confrontational, it’s not saying the engineers are dolts, it’s not saying it won’t work.
I have seen most of the information presented and understand the approach using the skin as a radiator, but I have also researched the viability of laminar flow in relation to heat/cooling transfer and what’s good for aero is not necessarily good for heat/cooling transfer.
MemberSeptember 21, 2021 at 8:02 am
Peter, at 30,000 feet the skin of the aircraft is subjected to -48 deg F (avg), I think that’s fantastic for aviation and you can reject as much heat as you literally want.
At sea level, with 80-90% humidity and 95 deg F surface temps, I am more curious how effective this will be.
MemberSeptember 1, 2021 at 8:17 am
“my understanding of their intent…”
That’s very vague. I’ll give it a pass for the moment until we see Beta and Gamma. I’m sure that this idea is not lost on the design team, as they want to place cameras for the side mirrors if they can get approval.
