Where, for how long and when? Certainly not when you need to regularly use a wood stove for heating, at least not around here in northern Europe. :)

I'm not sure where I read 1000W but it is for a square meter perpendicular to the sun's angle. Here in North East USA, solar installation folks say we get "3 hours" of direct sunlight per day in winter and 6 hours in the summer. I think that accounts for shorter days and weather.
