Interesting the house in the picture has a chimney and a highly slanted roof. It looks like it is in the north with lots of snow and relatively little sunlight

It seems like he's just running some calculations. Your upset about this seems pretty misplaced. Firstly, he didn't even say he would be buying Tesla cars - just two electric cars. And secondly, he didn't actually claim he had the resources to do any of this, just that he was calculating the ROI on doing it. Which is a figure that i'm interested in, even though I can't afford to buy a solar roof or two electric cars of any variety.

>If I put that same $40,000 in an index fund that got the stock market's historical 7% average, and waited 30 years, I'd have $308,000. Are you doing the math all in present dollars? Because the return is 7% after inflation but >10% before. So you'd have >500.000 in 2047 dollars. In this case it's important to do that adjustment because you're doing an investment upfront for payoffs over 30 years so the value of mone…
Energy prices, and thus savings, are certain to increase over that 30 years too. Quite likely at a rate exceeding inflation.
Solar leases use the 2% inflation rate too as a way to make them look more attractive (as does the solar roof calculator) but in reality electricity hasn't been getting more expensive at that rate.

Going off grid means you need a lot more batteries, which need materials and energy to make. Switching from gas to electricity for heating is a bad idea if there's still coal power stations in use, if you're not selling your excess power to the grid, they're going to turn on that coal power plant again. Sharing power is a much better idea than trying to store it in batteries, unless those batteries are in a car
> Switching from gas to electricity for heating is a bad idea if there's still coal power stations in use You misunderstand. Our solar installation will be expanded to cover the appliances. We'll be 100% off-grid. > Going off grid means you need a lot more batteries We only need 3 PowerWalls to cover all our needs (~1 for our needs now, 3 for when we have electric appliances and a car). That's not "a lot more". > Sha…
Sharing power via net metering is better (for the environment) because there's no conversion loss from charging a battery.

I'll bite...
No, we are not talking about minimum wage earners as very few can own homes. They are not in the solar roof market. The context is home owners.
In the US the average new car cost is $33,560. A $35,000 electric car is within reason and available on the market.
A roof is a 30 year investment. Cars are owned for much less time and auto transport is likely to transition to electric over the next decade or two. That means that in 10 years, my current gasoline cars will be worn out (I put a lot of miles on them) and I'll need to replace them anyway, and there are many advantages to electric cars.

I don't understand what you're advocating.
So the 1% have a different rational calculus -- you're saying it's simply wrong for them to discuss these things in a public forum, simply because it would make people with less money feel bad?
It's not like people are out here bragging about how much money they earn while screwing the little guy, they're just having a topical discussion about how much this product makes sense (or not).

That's pretty clearly a true statement. Qaq isn't claiming he is in this market. Just deriding the oft-expressed belief by people who are not in a market that said market does not exist.
> "$2000 earned by the cars while not used by owner", palakchokshi (it's clarified elsewhere in the comments that that's $2000 per month)
He's just running calculations? I don't understand what the problem with this is.
See my prior edit wrt the 3rd one.

I don't really see the selling point, or value here. Tesla's calculator estimates $40,500 for a roof that generates half our power needs, and should provide $20,400 worth of energy over 30-years. Add in a PowerWall and federal tax credit, and I'm still losing $15,400 over 30-years. If I put that same $40,000 in an index fund that got the stock market's historical 7% average, and waited 30 years, I'd have $308,000. To…
> Tesla's calculator estimates $40,500 for a roof that generates half our power needs, and should provide $20,400 worth of energy over 30-years. This depends quite strongly on where you are. Your numbers are very close to the ones I get if I use my correct address, which is in the Puget Sound area of Washington State.

Your electricity is probably a lot cheaper in Washington also and I'm assuming they have local rate information to factor in. Electricity is very expensive in California especially if you use PG&E since they use a tiered rate structure that goes from .12 - .50 cents. And very little of your usage is actually in that 12 cent tier for most people. In states like that I would imagine your solar roof could potentially pay for itself.

Seems off. Seattle gets 1/3rd the sunlight of California.
