I devoted a significant amount of time exploring the information derived 
from the above spreadsheet - including the time needed to read the 
(published) fine print on promising systems.

I ended up with two questions that published data cannot be expected to 
answer; both questions can readily be answered by responses to my 
original request (for observed performance of Canberra installations).

My questions now are:

1. What electricity outputs can be achieved in Canberra, given that the  
outputs are affected (to varying degrees) by the (internal?) temperature 
of the panels; and

2. How good were the quality controls of the manufacturing processes?  
What, if anything, went wrong and when?
Hence I repeat my request for follow-up information from people who have 
plunged into PV.

Since CLUG is not an appropriate forum for such information, I hope that 
Peter Barker's suggestion (to post the information to "Sustainable 
Housing" mailing list) will be taken up.
