ACTUAL data based on condenser air temperatures

Does anyone have an estimate
(hopefully based on some data)
of the loss of efficiency that occurs if you put the condensing unit on the roof in full sun?
can be provided with
a KNOWN manufacturer and model numbers.

MrBillPro made a statement earlier about a system where the condenser was inside the attic with the hot air vented to the outside. I cannot comment on the efficiency claims but can verify this system exist. It is found mostly in commercial applications. It is referred as a "Single Package Horizonal Unit". There is actually duct work for the condenser seperate from the conditioned space ductwork. A description and a picture of this design can be found in the following book:
