Welcome to Suntag

Suntag calculates the theoretical number of hours of sunshine for any location in Switzerland. Suntag takes into account both the relief around the selected point and the seasonality of the sun's path.

The Suntag Analysis is available as a standard and premium version. The standard version contains the PDF report in portrait format (sample) and the horizon profile as a CSV file (sample). For those, such as real estate agents, who want to include part of the analysis in their own documentation, the premium version includes the PDF report in landscape format without our logo (sample), the horizon profile as a CSV file (sample) as well as a ZIP file (sample) with all high resolution charts.

1. Enter the name of a location in Switzerland and press the 'Locate' button to display it on the map. You can also enter the latitude and longitude (e.g. 46.798509,8.231783) or simply drag the orange icon to the desired location. Zoom in until you are satisfied with the level of detail of the map.

3. You can now choose to purchase either the standard Suntag Analysis or the premium version. After payment, you will be automatically redirected to Suntag. The return to Suntag is necessary for the system to register the transaction and automatically send the files by e-mail.

4. After successful payment your files will be sent automatically to your email account. You will also be able to download the files from the website (here) for 48 hours after purchase.
