Will the sun shine?

As I sit here in the cold grey of a Scottish winter and remember seeing the sun for a total of one minute during the last three days, I'm wondering how practical a session of "solar navigation" would be and whether there is any way to find out how often the sun shines? I once spoke to the met office but they couldn't (or wouldn't) tell me. I've looked at solaration tables for solar panels, but couldn't separate out the "background - cloud" light level from the "sunshine" hours. So, perhaps someone here know? In particular I have the following specific questions (ideally for locations of Glasgow and London, summer/winter but any information, on any location, anytime would be better than none!): 1. Assuming a view of the horizon, how often can one see the sun at the moment of sunrise/sunset. 2. How often can one see the sun at the meridian? 3. Howmany hours of navigable sunshine do we get?
