Hence by

orientation the tank was still full of hot water.

Nothing wrong with the orientation. Anything from SW to SE will give
good results compared to the ideal direct southerly orientation. What
was wrong was the installation, in particular the setting of controls. A
good installer will return to check that everything is working well.

Indeed so. However IME when dealing with the far simpler requirement of
setting up a conventional heating system the combination of user
misunderstanding, incompetent installation and inadeqaute design and
broken controls is a large proportion of /all systems/.

The situation that AJH describes is absolutely typical of type of error
that users bring on themselves. With a solar assisted HW system the
possibility for errors are greater still.
