Same here- the US is 'power mad' when it comes to many things- 'utes' with 4 times the horsepower of my 8 tonne tilt-tray truck (and fuel consumption to match), HUGE electrical demand (some US fridges use more than my entire 3 bedroom house with three people living in it- including a 'gadget mad' older guy (guess who that was lol) and a teenager who never learned what an off switch was...)
Our daily consumption was around 7-10kwh a day- in total... running off an 80A 240v mains supply and 6kw of gridtie solar, the electricity bill was usually- zero...
(in fact we often got a few bucks back from them...)
Seriously lol
(they direct deposited the 'bill' amount on the due day straight into our bank account if it was a 'negative bill')

Many offgrid houses here in Australia comfortably run multiple A/Cs, cook on electric and have a lifestyle that it is hard to tell you are actually running purely from solar...
Of course solar here seems to be a lot cheaper than the US as well which helps- people quoting multiple tens of thousands for systems is crazy high price wise (gridties here cost about $3500Au or about $2300US- thats fully installed, no more to pay,and will give you about 35kwh a day in generation, where a 10kw system (requires 3 phase on at the house) is about $6500Au ($4200US) again fully installed, no more to pay, and will generate about 52kwh a day...
My own offgrid system cost me under $2000Au for ex gridtie panels (secondhand, from an installer doing upgrades/repairs) 72x 250W panels totaling 18kw of panels, the most expensive thing was the battery bank ($11800Au) for 20kwh of LYP batteries (better than LFP for either high or low temp applications) 16x400Ah cells- the total system cost $17500Au in total for everything... ($11400US)- sufficent to run a workshop with a mill and metal lathe, welders, air compressors etc, and a 3 bedroom house with A/C- in total that 18kw of solar will be getting up to 90kwh a day...
And I plan to buy an EV this year to boot lol (looking at the BYD Atto3)
all offgrid...
