I have some north facing panels in my config. Pretty shallow pitch on the roof, so almost flat, probably 15 degrees.
Anyway, they are there to capture summer sun, mid day. Obviously they don't produce much half of the year.
But an interesting thing I have seen is that on cloudy, overcast days, where there is no direct light, those panels out perform the south facing panels I have. Anyone smarter than me know why?
