Pulled a year of public solar energy data to estimate what a 22KW PV array would be like at my house, assuming daily consumption of 20kWh.

1. Data is per-day because I assume I'll have enough batteries to store 1 day worth of generation
2. It is super noisy, there are days when topping off with grid power is still necessary (about 400 kWh per year)
3. 18,000 kWh/year is wasted, unless I wanted to sell to the grid, and they don't pay much...
4. Though it requires a 192€/year interconnect fee, maintaining a grid connection is still cheaper than topping off with a generator.
5. It's basically infeasible to create an array so large that it will still generate enough in the worst months of the winter.
