For sure I used r.sun several times, I think als JRC is using it [0]

r.sun use raster as input, if you have high resolution raster data it
is not a problem if you computer is able to manage it.
I run r.sun using DEM with 40/30 cm of resolution.
I think that multi-threading could be used launching several r.sun job
in different cpu/core

there are already other addons using r.sun, maybe you can take some
