There are places, in Italy and Norway I think, that have villages tucked away behind mountains that get no sunlight at all for a good part of the year (AKA Lancashire) and to get around it, they have mirrors which focus the sun on to town squares and such. Makes me wonder if, seeing how much reflected light we get from the moon, if we could sprinkle the whole surface with fine glass then we could turn the moon into sun and save £b's on lighting here! Mind you, our government would probably go and sprinkle the wrong side.
