Welcome
Suntag computes the anticipated hours of sunshine for any Swiss location, factoring in the surrounding topography and the changing path of the sun throughout the year.
Moreover, Suntag offers valuable insights into average temperature, precipitations, noise levels (rail and road), public transportation options, and the accessibility of communication technologies such as coaxial and optical fiber, as well as 4G and 5G networks.
Suntag generates this information for any location in Switzerland in a few steps and puts it in a nice PDF format for you for only CHF 12.00. Simply click the 'Start' button!
Step 1: Location selection
Please enter the name of a location in Switzerland and click the 'Locate' button to view it on the map. Alternatively, you can enter coordinates in decimal degrees of latitude and longitude (for example: 46.798509,8.231783) or in the Swiss coordinate system LV95 (for example: 2660549,1183344). You can also directly click on the desired location on the map.
Mittelpunkt der Schweiz
After choosing the location, adjust the zoom level until you are content with the map's level of detail and click the 'Compute' button to initiate the analysis.
Step 2: Report Preparation
Suntag is presently generating your report. Kindly exercise patience, this process should take no longer than 10 seconds.
