At first i thought it a good idea to get lots of skylights pointing south
but on further investigation some say that they can get too hot in summer
and some say its best to have them in the north facing roof.

If you see a factory with a "sawtooth" roof, you will always see the
glass panels facing north - in fact that's what they are called - "North
lights"
