The 'somewhere else' is a big issue though. In order to deal with Northern Europe winter power demands you probably want those solar panels to be on the Tropic of Capricorn in the southern hemisphere.
That's along ways away. It'll take a lot of costly electrical infrastructure to move that power.
Even worse, if you want to work during the night, you also want the solar panels about 45 degrees west. So like in South America. Tough luck for those places where that sweet spot is in the middle of a large ocean.
