Earth axial tilt is 23.5°. For 11°N the solar altitude at noon of the equinoxes will be 90-11=79°; 90-11-23.5=55.5° at winter solstice and - it would be 90-11+23.5=102.5° at the summer solstice, but we normalize it to angle between nearest horizon and the Sun, so for values >90 we take 180-(value): 180-102.5=77.5° at the summer solstice.

The actual solar window though will be the range between minimum and maximum altitude: 55.5°-90° as the Sun passes through Zenith sometime in the late spring and early summer.
