Thanks Grassblade, true, yes its basically a geometric problem.

But, the mirror has some dimensions, and also the "detector object" (the one
that waits for catching reflected sunlight) is not a point, but a larger
volume. All the objects are quite close to each other.
So, I thought, I would have to do a separate calculation at least for each
of the four extreme corner points of the mirror, each of these calculations
variated by a range of points within the detector object. (Or, think
thoroughly about which ones to leave away...)
All of that for all different sun positions.

So, I thought, I let POV do all these variations for me.

Does this make sence that way?

Regards,
Philipp
