module_height documentation

[wholmgren]

Here, I don't understand module_height; does it not change with tracker rotation? Maybe axis_height and an internal calculation would produce module_height as an attribute, not an input parameter. In FixedMount, module_height is merely awkward, as the measurement that seems more likely to be at hand is the height of the bottom of the module above ground.

I'm OK merging this as is and improving in later PRs.

aren't panels connected on their mid of face. Which would then say height of module at mid remain constant if any rotation would occur rather than the bottom of it.

I would recommend to close this issue.

Totally noob so correct me if I am wrong. @cwhanse

Closing because 1) the current documentation is clear and unambiguous and 2) lack of comment on the definition of this term since it was added.
