Let me start here, if you look at my posts in this thread I often say that EV's are a good choice for some people, and from your description it seems like the Model Y is a good choice for your wife.
What ecoshit box does 10L/100km?
You may have noticed my name, all of my cars are Twin Turbos, one of which was manufactured in 1990 and that's the car I have owned for the longest. I also currently have an E92 BMW M3 Competition which does a comfortable 9L/100km out of town, even modified, not exactly an ecoshitbox.
More to the point you mentioned the Model Y replaced an SQ5 which most commonly has a turbo diesel 3 litre V6 and based on my experience does a comfortable 8L/100km out of town which by your km's I correctly assumed was most of the distances travelled. Of course it could have been a turbo 3 Litre V6 petrol which does a decent 9L/100km. I was conservative for both and used 10L/100km in the comparison of SQ5 to Model Y.
Raptor is around 15L on Premium and our SQ5 was around the same also on 98, so you can cut the figure in 1/3 again and re run those numbers for any luxury car.
You didn't mention a Raptor as being the vehicle replaced by the Model Y however if you had I would have used it.
We don't have a long range so Tesla recommend charging to 100% (new battery tech) compared to the long range.
An interesting choice considering the distances travelled. Almost all would choose a Long Range for the reduced range anxiety. We should discuss LFP versus NMC batteries later.
My partner works from home full time, she does the vast majority of her driving dropping kids off and picking them up in the morning and afternoon or visiting the office when she has to before coming home.
These trips are 1 hr trips each time so 2.5 hours of driving a day just for the kids not allowing anything else, we also run an Airbnb 2 hours away that is a 4 hour round trip we attend twice a week, the car charges in peak solar times 99% of the time it falls on charging while she works, we have a 30kWh home system (it was $20,000 not $40,000) this generates more than enough that our home bill is also $0 per quarter and covers any night .
This situation is most unusual, someone who does that many hours of driving and still has time at home to recharge is far from common. Most commute the distance, work 8 hours then commute and often arrive home too late for solar charging. Hence the need for home batteries. This rather unique profile would obviously change the calculations as you correctly point out.
missing anything instead of just asking how this was possible you've come up with a bizzare scenario in your head to suit yourself where I require $90,000 up front cost to charge this car for free when all that happens is I charge it from the solar that was already installed pre car purchase so a sunk $0 cost.
If you examine my calculations you will find they are not at all bizarre and I did explain exactly how I came to each number.
I love ice cars, you're talking to someone who owns a VL Calais, Honda NSX, HQ panelvan & Jaguar XJ12 as weekend toys.
I do the same, I have had 2 x XJ12's and I built a supercharged NSX in the 1990's. More than happy to discuss performance cars at any time.
a mode of low cost transportation you cannot beat an EV, it's the future and if it doesn't suit you because you cross the Simpsons desert every weekend that's fine for now but people are already road tripping the entirety of Australia in teslas.
EV's are easily beaten if you have no off street parking like 30% of the Australian population and have to pay for decent rate charging which costs much the same as refuelling an ICEV per km travelled. EV's become marginal when commuting daily and only have night time access to home recharging. EV's are less suitable when it comes to carrying passengers, luggage and even more unsuitable when towing, I have wasted far too much time recharging an EV on what would be a non stop trip in an ICEV (eg; to Jindabyne and return with the family and luggage on board towing the jet skis behind a Mercedes EQB.)
As I posted above, EV's are good for some people's situations but they are equally bad for other people, making the educated choice is the only way to choose and it seems that you have done exactly that.
buy your solar panels and inverters from reputable companies also, our panels are 30 years and our inverter 20) a battery doesn't make much sense while we still have 7 cent feed in tariff making up for night usage.
More than happy to talk to the "reputable company" that supplied your solar system. The issue I find often is that people confuse a Panel Performance Warranty of 25 years (which is the industry standard) with the Panel Product Warranty which is 10 years. The difference being that the Performance Warranty simply requires that the panel produce some electricity for 25 years, anything at all will do. Whereas the Product Warranty specifies by how much the performance has to drop in order to invoke the warranty within the 10 years. If I may quote a CSIRO Engineer "Many solar industry insiders consider the performance warranty practically worthless, little more than a marketing exercise."
In regards to 20 year Inverter Warranty, I can't say that I have ever seen an inverter warranted over 10 years. Even then they have such restrictive clauses that not much of the inverter is actually covered by warranty after 5 years. Again more than happy to talk to the "reputable company" and look at what brand of inverter and its warranty that they utilise.
On good days were hitting close to 250kWh generated.
What about on a bad day? I get up to a 90% reduction in power generation and that's in the Shire which isn't exactly climate unfriendly.
