I will look into C libraries. Does anyone here have a suggestion?

Before I go too far with this I want to check to see if the following
package could be used in QGIS.
astropy (https://www.astropy.org/) has a modified BSD-2 license. See
https://github.com/astropy/astropy/blob/master/LICENSE.rst
This would be the library I would pick. It might be an overkill,

GRASS does not seem to have lunar calculations. If it does it has not been
exposed in QGIS.

These seem to be basically what I am looking for, but they are an external
process that saves the results to a file. It would be nice to simply have a
method that returns the result. So now I am not quite sure how to proceed.
GRASS probably has the functionality, but not in the form I would like.
Hi Calvin, Martin,
forgot to say there are also grass functions to do this, namely
r.sunhours
r.sunmask.datetime
r.sunmask.position
see
https://github.com/OSGeo/grass/tree/master/raster/r.sunmask
for reference.
With this you can also get shadow areas from dems.
Best

Thank you for all the comments. To summarize.
1. Having this capability would be useful.
2. Take a look at pvlib.
3. Add it to expression functions and possibly add it as a core C++
function.
4. Take a look at GRASS r.sun and related commands.
5. Take a look at the astral library.
6. Take a look
