This task allows you to review the shadows cast by shading obstacles, undulating terrain and rows of modules on the modules in your site layout.
This task is only available (visible) when the currently selected site layout is showing fixed-tilt racks. It is hidden if the currently selected site layout is for single-axis trackers.
Press the 'Run Shading Calculation' button. This may take a while to calculate depending on the size of the site layout.
Once the calculation has completed, switch the map to 3D view to see the results. The controls on the left allow you to change the day of the year and the time of day. The time control shows an indication of sunrise and sunset to help you gauge when the sun is up.
By default it will show direct lighting. Modules in direct sunlight are shaded pure white. Modules in shadow are shaded in dark grey:
You can change to see the diffuse shading on the modules instead:
