I'd like to use r.sun.hourly and r.sun.daily from within QGIS but it doesn't seem to be present in GRASS tools. I tried to install it using g.extension in the GRASS shell, but it says I have to run it with sudo, and sudo g.extension gives command not found.

I have QGIS 3.26, GRASS 7.8.2 Ubuntu 20.04.

Nota: r.sun is not even present in my installation...

EDIT I tried to open the GRASS shell and use the g.extension command like this :

$ g.extension r.sun

I get :

GRASS_ADDON_BASE is not defined

so I tried to define it :

and

How can I fix this?

  • Note that GRASS GIS commands like g.extension need to be run in a GRASS GIS session. You can either define environmental variables or simply use the --exec method, see https://grass.osgeo.org/grass-stable/manuals/grass.html#batch-jobs-with-the-exec-interface. This will set all needed paths as well. – markusN Dec 17 '23 at 21:15
