In most (sane) numbering systems, you can use a k in place of thousands, m in the place of millions, etc. Becuse all the numbers around the scale of energy use involving the entire monthly power consumption use of a heat pump in a cold climate as well as solar production and storage needed are in thousands, you will note I wrote all the relevant numbers with the abbreviation k, so 5,475 kwh is equivalent to 5.4k kwh.
Admittedly 5.4 mwh would have been more clear, but because megawatt hours is less commonly used and would involved useing two diffrent units next to each other I used thousands of the same unit for consistency. Please go back and re-read all of my comments with this new knowledge in mind.
Yes, many heat pumps are installed in warmer climates, though that is changing, but blowing through the entire yearly national average in three weeks and then doing it again is lot of power for a climate contentious and thusly presumably well insulated off grid modern house to use. (Also, if we go back to what this conversation is about, the original commenter gave no indication that they were in a very cold climate with thousand dollar a month heating costs in the first place.)
We are literally talking about whether it is practically possible for a major renovation to a lifelong dream home. If they are in love with an old poorly built and insulated home in a very cold area then yes, in a few decades when this do this they will have to have it insulated to at least modern standards and of doing so it’s likely worth it to go to far better, but that is a very long way from your position that no one could even think about it being feasible for anyone in a few decades.
Can I be sure what will happen decades from now? No, but I can say for sure that at the moment, if you want to add insulation to an existing older structure, and not do a complete rebuild, you end up with a structure which isn’t anywhere near as well insulated as a newly-built structure designed for efficiency.

For a modern well-insulated structure, sure. But a lot of US housing was built without insulation. And people live in it and would prefer to retrofit.

Again, where are you getting the idea that the original commenter has to be talking about being set on a old, poorly insulated home?
That’s pretty much what most retrofits in the US look like.
