Sorry, this may not seem to be directly related with the robotics.
But I thought people on this group who build sun tracker may help me.
Given

NOTE that it is possible to track the sun without knowing explicitly its azimuth an elevation angles. I'm not interested in this. I'm looking for the equations which will return the Sun's azimuth and elevation angles corresponding to given date, time and location.
