I live offgrid and rely completely on solar power and battery. A 200w portable solar panel charging a high quality (If a little poor in capacity) powerstation provides enough power for most technological luxuries I have found.
The panels and power station I got cost 400$ total. They can be placed anywhere in your yard that gets direct sun no installation required and you jut fold em up when you mow or whatever.
This system provides me enough power to get by in my technological convinences without much interruption. Its definitely possible to run out of power but I can adjust my usage accordingly when power availability becomes limited.
Also my mind has been opened up to the world of DC appliances meant for such systems. USB heating blanket and chair, cigarette plug electric kettles/coffee makers, cigarette plug ovens, portable washer+dryers, portable USBC charged monitor displays. Do they work as good or fast as their AC wall outlet equivalents? No, but they work and won't eat into your limited power nearly as badly. You would be surprised at how much a 10 watt electric blanket can keep you warm when its cold.
Its only when people want heavy appliances and big power hungry TVs/computers that you need stupid huge power demands. I don't need a fridge I just stock up on non-perishables, I don't need a microwave to zap fry my food or water I can fire up the propane stove, let the sun heat it up, or let a energy efficient dc appliance do it slowly. I don't need a big washing machine + dryer when a tubs, clothing scrubbers, and drying racks exist (or the small plastic portable washer+dryers). I don't need running water when I have a hand pump sprayer or battery powered pump or just take a farmers bath. I don't need electric heat or AC when smartly placed propane heater and box fan are a thing.
Guess how much my electric, heating, and water bills are? The only thing I still pay for now is propane which comes to around to 1-2$ per night in heating depending on conditions.
And I still get to enjoy many luxuries and comforts of modern life. Coffee in the morning, YouTube, video games (on a laptop, god I want a steam deck) music, reading, and a comfortable bed.
So many people live just below their means paycheck to paycheck unwilling to give up the tiniest bit of convenience in order to save big $.
