How to set multiple pipe components as input for Sunlight-Hours-Analysis-Component

Hello!

I wonder how to plug in several pipe components as input for 'geometry' and 'context' of  the Sunlight-Hours-Analysis-Component (without baking the geometry to rhino as I want to alter it with octopus) and hope somebody can help.

As I'm quite new to grasshopper. I guess it's something basic I missed here. I tried to collect all the pipes in a sinbgle brep or a surface component to further transfer the information to the sunlight hours component. But  as it seems, I don't know how to do that.

A screenshot and the grasshopper definition is attached.

Thank you very much!!
