The Swiss Federal Office of Energy SFOE, the Federal Office of Meteorology and Climatology MeteoSwiss, and the Federal Office of Topography swisstopo have created together with Meteotest a stunningly interactive and publicly accessible solar potential estimator for whole Switzerland.
Solar Potential Map of Switzerland
Compared to traditional so-called GIS-type “solar cadasters” this one is really usable. By usable I mean:
- loads incredibly fast
- step-by-step increase of complexity
- order-of-magnitude yield and cost of PV and heating system within 10 seconds
- all the options for professional users upon demand
- last but not least: open government data!
One click to the solar yield calculation of your roof!
I’m of course a bit biased since I created and provided the satellite-based solar irradiance data to the project as part of my engagement within MeteoSwiss. But try it out yourself!
