This answer depends on latitude. I believe your answer is only
valid at the equator.

Actually it's valid up to the pole.  Even in mid latitudes, the sun rises
north of due east for 1/2 the year.

But as you say, at the pole there is no 'north side' ;-)

Given that the earth and sun are closest in January (as per your previous
annotation), there is a slight advantage to shading the south wall over the
north (if you can only shade one)
