    • Sonnendach makes it easy to assess the solar potential of any building in Switzerland, from single-family homes to industrial facilities. Using geoinformation data, the tool analyzes all roofs and façades for their suitability for solar energy use. By entering an address or navigating the map, users can explore detailed solar potential, including how much electricity or heat a solar system could generate.

      The tool also provides financial insights, showing potential savings from self-produced electricity or profits from selling excess power. By clicking "How much will my photovoltaic system cost?", users can access SwissEnergy's Solar Calculator for a more detailed project analysis.

      Sonnendach.ch serves as a valuable resource for individuals, municipalities, and energy planners, making the solar energy potential of Swiss rooftops and façades visible and actionable.
