Definition
Horizon profile is the azimuthal elevation angle of distant obstructions (mountains, ridgelines, distant buildings) around a solar site. Input to PVsyst's far-shading analysis as opposed to near-shading from immediate obstructions.
Key Takeaways
- Horizon profile = distant obstruction elevation by azimuth.
- Used for far-shading analysis in PVsyst.
- Distinct from near-shading (trees, buildings within site).
- Mountains can shade morning/evening hours seasonally.
- Site survey LIDAR + DEM data typical source.
Frequently Asked Questions
2 commonly searched questions about Horizon Profile.
What is a horizon profile?
Elevation angle of distant obstructions (mountains, far buildings) measured around the azimuth circle. Captures far-shading impacts on solar yield.
How is it measured?
Compass + clinometer at site; LIDAR + DEM data; or sun-path photo analysis. Entered into PVsyst's Horizon dialog.
