Sure, but we still need heating. For instance the last days (-8℃ to 6℃) from 17:30 to 10:00 in the morning I need from 1 to 1.8kW constant power for main home heat pump and VMC small one. When the Sun shine I do not need heating, large glass surfaces on the south side get enough heat directly from the Sun, but from p.v. I have around 3 hours with enough power for doing useful things, like dishwasher, washing machine, hot water heater etc not more now and Sunny days are still very few compared to cloudy/rainy/snowy ones.

In the coldest part of the winter (-25℃ to -3℃) sometimes I need 3kW just for heating. And even if not much used I also have to recharge my car witch eat around 60-70kWh/week.

If you go northern, for instance when I was in south Sweden the home ALONE, witch was not super-new but still relatively new and well insulated, eat around 60kWh/day...

Sure, from late May to September from the grid I consume VERY little, but as I said I live all the year, being unable to hibernate like bears...
