My first iteration of the array (when I was living in the tent) was 800w, so on a bad winters day, I would recover 1.8 kwh of power. 1.8kwh was more than my well has ever used in a single day (sure, it's a 1500 watt pump, but it runs for minutes per day), and would run the few LED lights I was using at the time for days (an LED bulb making the same kind of lumens as a 60w incandescent only consumes 8 watts or so, which means that on my worst case days, I get enough electricity to run one for over 200 hours). Similarly, my microwave internet would pull around 150w at peak use, so 1800wh will more than supply me with my daily internet fix. It did mean that I would refrain from charging power tool batteries or running any 120v tools on the inverter. Theoretically, if I was getting that kind of solar performance in the summer, the refrigerator I had would be a problem
(the chest freezer is efficient enough that it would be fine), but I only ever see solar days that bad in the early winter, and I would unplug the fridge and set it out in the cold when I was living in the tent with that version of the solar array, and only bring it inside if it was going to be below 0 degrees F.
On a sunny winter solstice day, I'd get more like 80% of the rated efficiency of the panels, so I'd get 4800wh if it was the shortest day of the year. This was enough at the time that I didn't really need to conserve electricity for normal living and just didn't want to do any construction projects.
The solar array that I have now (and that I had by the time I paid for the grid connection) is 8000w instead of 800w, so I only had to worry about the jet pump on the wood fired spa, the welder, the mill, etc.
