Sun Position Calculator

Hi All,

Does anyone knows an algoritmh to calculate the sun position given the GPS coordinates and date?

The goal is build a solar tracker, the input is GPS (coordinates and date time). From this I can calculate the azimuth and inclination of solar panel. Using a electronic compass and a tilt sensor I can position the solar panel with precison. I have a C source with the algorithm, but since I dont have a lot o time to implement I ask if anyone have / know a pascal source.

Thanks in advance

Hi Avra,
Thanks for your awnser. I did google around. And I did misss this one. This is not quite what I want, because it lacks the coordinates (latitude and logitude), but is a good starting point.

I have just poped up on this code. It can't be simpler then this:

Long/Lat in Delphi instead of C:
