Insolation

Calculation of insolation and shadows based on relief

For areas, slopes and areas where understanding the direct sun window is important: A-102 builds a relief horizon around a point and shows when the DEM relief covers the sun.

Open insolation calculation Calculation Limitations
Relief horizon Shadows by DEM 3D animation of the day Solar panels
1 point for solar analysis
DEM 30 m if there is coverage
3D animation for Premium

What you can check

  • Sun altitude, azimuth and periods of direct sun for the selected date.
  • The relief horizon around a point and the influence of slopes, hills and elevation changes.
  • Preliminary efficiency of solar panels taking into account shading by terrain.

How does the calculation work?

  • The user selects a point on the map, date, installation height and analysis radius.
  • The service builds DEM profiles in directions around a point and compares them with the position of the sun.
  • For Premium, saving the scenario and daily 3D animation of the sun, moon, shadows and relief are available.
Questions

Frequently asked questions

Does the calculation take buildings and trees into account?

By default, the calculation shows the influence of DEM terrain. Buildings, vegetation, temporary objects and weather are not taken into account unless the interface explicitly states otherwise.

Is it possible to evaluate solar panels?

Yes. On the Insolation page, you can set panel area, efficiency, azimuth, tilt, and system losses to get a preliminary estimate of clear-sky daily output.

Can the result be used as an engineering project?

No. This is an information and analytical assessment based on DEM relief. Meaningful decisions require independent verification, actual measurements and equipment design data.
