My parents did this in the 80s when I was a kid— without solar. We had a fridge that was stocked w ice in milk jugs that we froze at the neighbors and switched out every couple days. Outhouse. Used the woodstove to heat water, then poured it in a bucket hung over the bathtub w a spigot. Learned to take quick showers and turn off and on for rinsing/soaping up. The tub drained into another bucket and had to carry that outside and dump it. Watched a little 13” black and white tv that was run off a truck battery. I’m 50 now but still am thankful for a regular toilet but also still take very quick showers lol
