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.
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
You're making zero sense. What is your argument I don't even get it.
