or you get a battery. Is just great. I have 3.5kw solar power witha 9kwh battery. Very very seldom it switches to power line. And this is in south Germany, maybe a bit sunnier than north but still - it rains a lot/cloudy, sun is sparse.

It seems like that works for daily cycles, but isn't that very expensive storage for one cycle a year, which is what you need to save energy for winter?

Depends how close to the poles you are. A lot of the world can do this fine by sizing the PV for winter; too close to the poles and there's not going to work — you either need to diversify power generation by kind (wind, wave, hydro, geothermal all work too, but again geographically constrained) or by distance (the maths says we can build an adequate and literally global power grid for an affordable quantity of aluminium, shame about the politics).
