Solar is quite poor in Northern winters. Wind + solar + heat would be a better bet, but the battery required to heat your house for more than a day with low winds would be prohibitively expensive unless you added geothermal to the mix like a geothermal heatpump which is also very expensive. Betweem the gear, battery, geothermal, all installed your probably in the 80k$ range or more. A wood stove would be the best bet
Good point, for aome reason i was thinking more off-grid than load balancing economics. The battery would probably help lower power by filling when power is cheap and supplying when the rates spike throughout the day
What about a solar + electric heating?
Well, here (in middle of finland) the sun set at 14:30, so there wasn’t all that much solar energy available.
Also heat pumps are always at least as efficient as straight electric heating.

Finland has about 5.2GW of wind capacity vs 4.3 nuclear. If it’s a windy day the spot price will usually be low.
