LB Solar Envelop_mesh (is Flip Mesh required?) > LB Direct Sun Hours_geometry

I am going LB Solar Envelop_mesh to LB Direct Sun Hours_geometry; the Direct Sun Hours output seems off based on sun locations; I flip mesh and results seem better; is this a bug or are we expected to flip mesh? Solar Collector boundary representation

It’s not a bug. It’s just not necessarily a workflow that we designed for. Generally speaking, you’ll want to make sure that any geometry you plug into the Direct Sun Hours component is facing the direction that you intend it to.
