Notes:

This tool is provided for estimation purposes only, no responsibility is taken for the accuracy of these calculations.

The longitude and latitude can be found on pvgis.

Times of sun rise and sun set do not take account of atmospheric refraction and relative elevation. Times shown are simply when the sun's altitude is 0°. In reality, the sun is only hidden when it is about 0.84° below the geometric horizon. This is due to the atmospheric refraction and the apparent radius of the sun which is 0.27°.

Sun path

Understanding the motion of the Sun is essential for proper solar systems design and the choice of proper location for solar collectors or modules. The solar path is described with the Sun path diagram. The Sun path diagram is a very useful tool in the early photovoltaic system design phase for shadowing determining.
