I'm trying to calculate the angle of the sun above the horizon on a given
day for shading purposes, any program known here ?

Thanks Richard

This site does great sun charts for any location -- you can read the
solar azimuth and altitude from the chart:

 The max sun elevation is 90-lat+declination, and the declination is 23.5
max on 6/21 and -23.5 min on 12/21 and varies sinusoidally over the year.
