Azimuth and Elevation angles
The azimuth angle and the elevation angle are the two key angles which are used to orient photovoltaic modules , In any time (day/month/hour/minute) , the azimuth and elevation angle determine by the following equations :

In any time in the year you can determine the sun position according to above equations, the input of this equations :
- the time ( day/month/hour/minute/time zone)
- the geographic Information ( latitude , longitude )
- the time ( day/month/hour/minute/time zone)
- the geographic Information ( latitude , longitude )
Sun Path Chart
This chart demonstrates the path of the sun in the sky for specific geographic position all over the year
as we see the path of the sun is shortest at 21Dec and longest at 21Jun
