Multi-Directional Opposing Bottom and Top Feed Arrays
Collector arrays that face opposing compass directions are not recommended unless
the roof pitch is less than ~15˚.
In this case the temperature sensor should be installed
at an angle that is an average of the two collector array directions. Installations with a
purely south facing facet are still not recommended for southern areas of Australia.
Why?
Depending on the location of the roof sensor the controller could turn the system
on with one bank of collectors in full shade.
