Location
The location sets the position of the Sun at each hour of the year, the climate that is downloaded and the time zone. Without a location you cannot simulate.
How to enter it
- Search for an address. Type the address and press Search; OpenStreetMap (Nominatim) is queried and you choose one of the results. The altitude is filled in automatically with the Open-Meteo elevation service.
- Click on the map. Click on the site.
- Type the coordinates. Latitude and longitude in decimal degrees (north latitude and east longitude positive, for example
42,7896and-1,6496) and altitude in metres.
If the address service does not respond, the application tells you and you can carry on with the coordinates by hand.
