Too close to the equator and/or lack of regular rainfall and you get problems with dust accumulation on the panels. Also, heat does not really help PV efficiency. The latitudes in Germany may not be perfect for PV, but they seem to be much less bad than one would initially expect. (I do find PV-covered landscapes visually less appealing than wind farms though, but of course PV must be much less annoying to live close nearby, haven't tried either. PV is competing with agriculture in a way that wind does not, so maybe we shouldn't overdo PV buildup on arable land..)
