It’s still not earning you money to spend electricity because you still have to pay the transfer fee which is around 6 cents / kWh but it’s pretty damn cheap nevertheless, mostly because of the excess in wind energy.
Last winter because of a mistake it dropped down to negative 50 cents / kWh for few hours, averaging negative 20 cents for the entire day. People were literally earning money by spending electricity. Some were running electric heaters outside in the middle of the winter.
No, you can’t. You can’t get the same of solar energy in Nordic countries as in Sahara desert. It’s simple, you can’t. Totally different ratio of solar energy per square meter by ranges making it in north Scandinavia virtually unusable
You see, “Other countries” includes the rest of the world. You build whatever fits the country, be it wind or solar or hydro. I don’t understand what you’re saying.
If you don’t know what energy output per meter is, total output and total cost of solar panel ownership, how it varies across geography in relation to equator, the fact there is no cheap way to store it (or you have to use it somehow in that very moment), it means it’s pointless to talk any further. Simple physics. It doesn’t matter though whether if it is solar, wind or water
This post is about Finland. If fucking Finland has too much energy, then Sahara has too much energy for sure
You missed the point entirely. Finland has little to none solar energy. They have only wind and water energy. Same with most Nordic, Baltic and northern Poland. There is not enough solar energy provided by sun to make it affordable ( whole life cycle including utilization costs )

Typical per capita electricity consumption in developed economies is 6–12 megawatt-hours (MWh) per person [4]. This may double to around 20 MWh per capita [5] to accommodate electrification of most energy functions.
-
The power and area of solar panels required to supply 20 MWh of electricity per capita per annum are 14 kilowatts (kW) and 70 m2, respectively, assuming an average capacity factor of 16% [7] and an array solar conversion efficiency of 20%.

For ten billion people, this amounts to 140 TW and 0.7 million km2, respectively. This can be compared with the global land surface area of 150 million km2 and the area devoted to agriculture of 50 million km2 [8].

The simple calculation above shows that the world has sufficient land area to provide energy from solar PV for ten billion affluent people.

TL; DR; full solar electrification with current technology for 10 billion affluent people is possible if we dedicated less than 2% of the real estate currently in use by global agriculture to electricity production
I live in Finland. Can confirm we have solar energy. It’s extremely useful considering that in the summer we have near 24 hours of sunlight.
