There is one thing that I am curious of:
What are some rule of a thumb, or approximate overall piping lengths in residential solar water heating systems?

I know it may be difficult to answer this question, as it depends on a lot of factors: whether or not a swh system's storage is right next to the collector (ICS, thermosyphon), or located in the basement.
I also understand that it depends on the number of floors, position of a collector (on the roof, on the ground) and some other factors too.

But for example what are some approximate values of piping lengths for ground floor + one/two floor houses with collectors on the roof, and storage tank in the basement or ground floor?
70 feet? 150 feet?

Just to clarify: I am not interested in losses of energy due to piping. I am just interested in the overall piping length.

Thank you for the reply, and I apologize if it is difficult to answer this question.
