An observation about solar orientation: it's 9:45am in Tucson. The south wall is in sun, but the angle of the sun is very steep - a 2" overhang is casting a 3' shadow. The north wall is completely in shadow right now. I need to check again at noon. This is not what my naive understanding of solar angles would suggest - hardly shocking, but something I need to think about.
