That Ladybug Radiation component is only designed to give cumulative radiation and it’s not going to give you hourly radiation unless you want to look at a specific hour, in which case you can plug an HOY into the sky matrix component.
If you want radiation for every hour of the year falling on an unobstructed surface, you can use the LB Directional Solar Irradiance component and that should be relatively fast and straighforward. Otherwise, if you need to account for context shade, you’ll have to run a more advanced study with Honeybee using the Annual Irradiance recipe.
