I haven't checked but our house barely gets any sun. Frost stays around all day. One advantage though is that we rarely get any wind. Nasty when we do but not very often.Long and short of it is; solar is cheap, if you can use the energy it pushes your way. If you can't use it all, scale back the array or, maybe, or maybe not, consider a battery.
Fizzy, you think your house wouldn't be suitable? Have you actually checked what your output would be? I mentioned previously you could check using pvgis. Why not check...?
Perhaps I will check do you have the link again?
