You can use Prospect’s horizon editor o customize the horizon profile by following these instructions:
Here is how you can download the horizon profile in Prospect:
See more info on our section Integrations if you want to use it on third-party software.
By default, horizon shading is considered in the Prospect app and there is no need to apply it additionally. You can read about the source of horizon data on our website. Our team has invested a lot of time in fixing errors in publicly available terrain datasets such as SRTM and patching together multiple data sources, to create a global terrain database at 90 m resolution with almost no gaps or errors. The horizon data is then created from this terrain database.
Prospect shading includes PV system self-shading and far shading from the horizon profile. This loss is the difference between the “theoretical” and “site specific” global horizontal irradiation (GHI).
This calculation does not include the effect of shading from nearby objects. However, you can edit the horizon profile using the horizon editor to include the effect of shading by modelling the elevation angle of nearby objects for each direction (azimuth). Please note that this will only result in approximate results, since the effect on electrical generation of partial shading on the modules will not be taken into account.
