Fridges take a LOT of solar to run. Lights (especially LEDs) and tech gadgets are easy to keep running, but heat, A/C and fridges are power hungry. Also, I had a shallow hand pump well installed in my back yard. 35’ down to cool fresh water, no electricity required, cost a thousand bucks installed. Don’t forget that if grid power goes down, most public water systems will fail shortly after. Even electric well pumps that run on grid power will fail. You can’t live without water, period.
Well, a fridge generally goes through 1 kwh or so per day. If you can end up using a 1 kw system (and, assuming, you have the equivalent of 8 hours of sun a day to run it), you should have plenty of juice for the fridge plus a reasonable number of lights and your FR machine. But not for a/c or electric heat.
Won't water the landscape sprinklers, but can shower, shave, cook and poop.
