Re: Don't want. Don't need
Maybe they live at one of the poles, but also in a valley? So they are currently getting 600W, so in 4 hours time the sun will set for them until next year. A bit niche, perhaps, for a solar panel installation.
FWIW, the place with the lowest amount of sunshine per annum is Jan Mayen, a Norwegian island. A piece of land near Greenland. This is one of the darkest places on the planet that gets only 823 hours of sunshine a year
