In the summer the sun is more directly overhead so the extra glass on the
south side should not make the house hot.in the winter the sun is lower
on the horizon so it shines in through the glass more.

The rub to this argument is - more HOURS of daylight in the summer.
This fact coupled with higher outside temps, WILL MAKE A HOUSE WITH
SOUTH FACING WINDOWS WARMER IN THE SUMMERTIME THAN A HOUSE WITH NO SOUTH
FACING WINDOWS!!!

Please don't yell. It's completely unnecessary. It's not hard to make the
south facing windows work. You need overhangs, as pointed out, but the
angle of incidence, along with the right kind of glazing makes it entirely
possible to restrict heat gain. In Northern latitudes, what may be much
worse for causing overheating is large glass expanses in West windows.
West windows get little to no heat gain in Winter, but can't be shaded by
overhangs in Summer. I've got lots of south window, but it never gets hot
in the living room until the sun starts to set.
