This widget belongs to a group giving the position on earth. This is the most classical way to enter data relative to astronomical quantities on earth. User have to set the time (day/month/hour/minute) to calculate for any point on earth the position of the sun throughout a standard year.

The exact Direct solar energy contribution may then come either from a blackbody model or much better from a weather data file in which direct and diffuse solar energy are given every hour. One reminds that the weather data file has to respect a proper format (see documentation) and that its name has to be given in the "File Names" window.

It means of course that the component (generally a building or more generally an object) has to be oriented correctly.
