 Efficiency of your inverter.
 
+#### Shading
+In this section you can define the shading on your solar panels.
+For each azimuth angle range, you can specify the minimum elevation of the sun that is necessary for the sun to hit the solar panels.
+For elevations below this value you can set the percentage of shading. For example, a building will reduce radiation by 100%, a tree maybe only by 60%.
