Loss due to shading

Each solar panel's losses due to shading are obtained based on its shading profile, which is formed by the shadows cast by the architectural elements of the linked model, the solar panels themselves, nearby buildings and other obstacles in the environment.

Using the “Loss due to shading” option in the editing window of each panel, an associated shading profile can be consulted or edited:

  • Shading polygons
    At the top of the panel, users can consult or manually enter the polygons forming the shading diagram using the following tables:
    • Superior (Solar azimuth 1 (º), Elevation 1(º), Solar azimuth 2 (º), Elevation 2 (º)
      Enters shading diagrams starting from the vertical line (90° elevation).
    • Inferior (Solar azimuth 1 (º), Elevation 1(º), Solar azimuth 2 (º), Elevation 2 (º)
      Enters shading diagrams starting from the horizontal line (0° elevation).
      • Creating a polygon using the simplified option
        This option opens an assistant that allows users to generate a shading polygon by entering only the element's orientation (south, east, northeast, northwest, southeast or southwest) and the distance and height data of the obstacle's mid and end points (d, d1, d2 and h). The points of the resulting shading polygon are shown at the bottom.
  • Shading diagram
    This area displays the cylindrical solar chart, which indicates the position of the sun for each date and time of the year by solar azimuth and elevation, together with the defined or calculated shading diagram.
  • Keep the shading diagram during the analysis (optional)
    If the obstacles are not entered and the shading diagram is entered manually, this next option must be checked so that the shading diagram entered is preserved and not calculated.
Note:
Using the options available in the “Update results” tool in the ”Calculation” group, users can carry out an analysis with a simplified shading diagram with a smaller number of sun positions to reduce the analysis time.

The worst shading factor of all panels in each branch can also be considered for all panels.
