I'm in the UK. I covered my whole roof with 6.5kW of panels (it's pretty ideal south facing etc.)

I just checked our stats. Average consumption 16kWh/day. Sunny summer day we get 30-40kWh. Sunny winter day 10-20kWh. Cloudy winter day it's 0.5-2kWh.

Also that's without a heat pump... Which you mainly use in the winter.

And without an electric car but I doubt they're as big of an issue because you can charge them from cheap overnight power anyway.
