re: Assuming most new cars will be EV's by 2030...how to future proof a new home's garage?

Depends on how fast you want to charge your cars.
300 miles of range in under 8 hours if I can for at least one garage bay. A 10-12 hour charge time would be okay for the secondary bay. The tertiary bay can be a trickle charge....but ideally I could just run the charger to whatever car needs it between those two spaces.
Hard to imagine needing a combined 900 miles of range in a single night between 3 cars.

Building a new house soon. Was going to give it a shot. I really like the Tesla Model X
If I was building a home I’d put it in during construction. I imagine that while the plug/charger might be different you could at least set the wiring up in the wall/outlet

I guess you can spend a fortune on a solar panel array if you wanted to, but the folks I know with them in Chicago almost never produce enough juice to power the home and have to rely on the electrical grid. Louisiana has slightly longer days, so it may be different.
The sizing of the solar array really depends on a lot of factors, much more than just latitude. A good company can design and simulate a system to give you and idea of what your offset would be. Its too highly dependent on individual characteristics to generalize. Some only offset 50%, others 120%. It depends.

And some neighborhoods don't even allow solar arrays.

The real question is, how long into the gas-less society before there is another "Great Dark Age" where the people have no electricity and noone remembers or understands how fossil fuels worked and have to start all over from scratch?

Has the Tesla Solar Roof worked out?

What is the outlook for lawn and landscape companies? Impossible for me to keep my current customer base if I have to go all electric.

The tech who will install my car charger in 2030 is currently in the 6th grade. I’m ok with it.

Yeah some HOAs get shitty about them. If you really want to fight it, sign up with one of the big boys and they'll send the lawyers in. I have yet to see an HOA not fold when pressed. Not saying its right or wrong, because I agree the panels are ugly AF.

Average day length on an annual basis is the same. Chicago has longer days in the summer and shorter days in the winter than Louisiana. The angle of the sun is different, which may matter.

Short answer is yes from a production point. The data is impressive, the price is not. And there's only HALT testing for reliability and durability because it has such limited deployment.
ETA If I build a house in a couple years I'll put this and a few PW3s on and basically be off grid capable.

just because we are headed in that direction, doesn't mean we will be remotely close to that by 2030. Not even remotely fricking close. And if we are it will be one big lie, because sure your vehicle may not be fossil fuel powered, but guess where the electricity used to charge it will come from? yup, fossil fuels. And the plastics, rubber, byproducts, etc that make up that vehicle....guess what those are produced from? yup, fossil fuels.
The only companies participating and pushing to meet that goal are banking on government subsidies bailing them out when it doesn't happen. And likely a bit of virtue signaling at the same time. but yeah, go ahead and spend that $ on outfitting your garage for something you won't need.

I think the current Tesla charger maxes out at 48 Amps. It’ll work with much less, albeit slower.
So basically just wire the garage for one of those per bay.
Would anything need to be upsized elsewhere in the house to handle up to 3 cars charging at once?

It’s difficult enough to find qualified roofers after hurricanes on the gulf coast. Not sure if people down there should make it even harder by having solar shingles just yet.

I’m not sure why this upsets you so much. These are not insurmountable engineering and infrastructure hurdles.
are you kidding me?
the average home is not setup to have something like this, and will require a couple thousand dollars to get set up.
There are almost 300 million cars registered in the US, more than there are people.
even if you just assumed half of them were regularly in use, that's an extra 2.6 BILLION Kilowatts being used to charge them. Just for some comparison sake on what 2.6B KW of electricity is, NYC uses about 11 million KW of electricity a day, so you're talking about adding the equivalent of 236 New York City's to our electrical infastructure.
So sure, it's not insurmountable.

110v is the standard input for EV chargers

fair point. It'll be interesting to see how they hold up to high winds, hail ,etc. The testing looks good but only time and exposure will tell. Of course, if the roof flies off that won't matter. Posted on 2/5/21 at 12:29 pm to dewster

Unless you’re all driving hundreds of miles per day I don’t think that’ll be necessary. What I expect to happen is that somebody will make some smart power distribution hub that intelligently charges multiple vehicles and has an app interface to customize settings.

How many outlets and how many amps would be required?
You need to consider what your driving habits are and how that will impact charging. I know a few people with multiple EVs and they all have 1 220V charging station. Unless your really driving a lot you won't be charging them every day, or even every other day typically. Plus you can have 110 chargers that you can just plug in to a normal outlet.
Of course you can add more for more flexibility. Hell, you can throw a solar array up with an inverter that has a built in charger so you charge directly off your solar during the day if that would work.
