Of course. Annual radiation studies that model radiation at every hour of the year is one of the main reasons HB+ was created.
Try looking at the 05_annual_radiation_gridbased.gh example file here:
If you update your components to sync with the github, you will see that you can also run radiation studies with ASHRAE Clear Skies, which are particularly important for radiation studies related to HVAC sizing.
Note that, while you can use the file above to get cumulative radiation, actual studies using cumulative skies are not yet implemented in HB+. All of this is to say that these HB+ examples might be a bit overkill if all that you need is just the total radiation falling on a surface over the year. If that is all that you need, you might be better off using cumulative skies in legacy HB for now.
