Hi,
Wouldn’t knowing the incident radiation on the surfaces be better?
To achieve this, you can use the LB Incident Radiation
component, if you are using LBT 1.1. That way you can get an overview of the incoming solar radiation in kWh/m2, not just the hours.
This thread could be helpful:
For the legacy plugins I think it is the Ladybug_Radiation_Analysis
that would be helpful.

To cull the mesh, you need to create a pattern with a conditional statement with GH componenets, alternatively you can try the Mesh_Threshold_Selector
.
