The issue is the batteries. You need a detailed "load analysis" to accurately determine how much battery storage you will need.
Your load analysis will differ in different geographical locations and the time of year. There is one YouTube channel where a family built a reasonably sized house (2000+ sq ft?) with all of the typical amenities (washer, dryer, dish washer, propane for cooking and hot water). They have 3 HUGE sets of solar panels. Because they live in ID, in winter they some times go 3 or more days with no real sunshine. They have a large propane generator.
