Problem with getting monthly irradiation results from multiple surfaces


I’m trying to plot a monthly irradiation for multiple surfaces in order to integrate with solar panels. And I came across with this issue while I am working with extracting a total monthly irradiation results from several surfaces.

As you can see from the screenshot below, it has a total of four surfaces, and each of them has 60 sensor points. Now I got the monthly data from each of these sensor points in each branches. And I was trying to get the each surface’s monthly irradiation result. But I haven’t find any nice way to solve this other than exploding the tree and do it one by one. So, it would be very great if there is component in HB-Radiance can handle this.

I guess there might be other way to play around? Any suggestions and insights will be much appreciated! (17.1 KB)
