What @AbrahamYezioro said. Maybe it will be helpful to review what question each diagram is trying to answer.
Radiation rose is useful when you want to know how much radiation you get on a surface with a fixed tilt from different orientations. For instance before you start the design you want to know what is the difference if a wall is facing east vs south. Then you can use the
radiation rose to get a sense. It’s similar to what
wind-rose is for wind direction and intensity.
Radiation calla dome, on the other hand, is designed to be used when you want to know how much radiation you get on surface with different tilts and from different orientations. It’s useful when you want to figure out what is the best tilt and orientation for PV panels in a location.
We can implement the context input to Radiation calla dome as well. It has just never came up otherwise there is no technical limitations to add a similar input to call dome.
