I expect you are aware that comparing results between two probably wildly
different calculation tools is difficult, in general.

Welcome! And good start.

Basically, you can extract a lot of data for every individual surface.
Depending on the platform you are using, I would suggest using bash scripts
to drive res for extracting the results.

There are two variables available, "solar entering zone" and "solar
absorbed". The first includes fraction reflected outside. The second is
likely what you are looking for.

I do not quite understand what you mean here. You may want to slightly
elaborate.
