Compound Angle Tool

Solmetric’s Compound Angle Tool is a free downloadable tool that simplifies calculations of multiple compound angles in solar energy installations. Set azimuth and tilt of the primary plane (eg. roof) and the secondary plane (eg. modules), relative to the primary plane. The compound angle (azimuth and tilt) will be calculated relative to horizontal (true).

The Compound angle tool is a free downloadable tool to help calculate compound angles for solar energy installations. The following information is provided by the user:

  • Roof plane azimuth
  • Roof plane tilt
  • Module tilt relative to roof plane
  • Module tilt anchor edge (top, bottom, left, right)
The resulting true azimuth and tilt are computed and displayed.

The view can be adjusted to be from the South or 180 degrees as normally done for the Northern Hemisphere, or from the North or 0 degrees, as normally done for the Southern Hemisphere.
