Good job... where do you live though? That really determines what your options are.
I've got >5,000 square feet, but a climate that is quite moderate/low latitude and currently have 8.3kW of PV. 20kW would give me about 99.5% availability with a 3-day battery. Average daily is 30-35kWh, one EV that does about 150-200 miles a week. (50kWh.) We have mini splits in the bedrooms only, which works fine here. My IT load is ~7kWh/day, and across all the refrigerators and freezers we have another 6kWh. No hot tub or sauna, but that would easily add 15kWh/day.
But, if you use 80-85kWh/day then maybe you should focus on energy efficiency strategies. If that isn't your thing... don't complain about higher energy bills.
