Tilt
The tilt represents the angle/pitch of the roof. For common pitch values (from 1:12 to 12:12), see the chart below for corresponding tilt values in degrees.
HelioScope assumes a top-down orthogonal view, so the module quantity that can fit a rooftop will change based on the tilt. In the example below, a rooftop at an 18.4º tilt can hold 26 modules, while at a 45º tilt it can hold 32 modules:
