Hi
Following the Shamim question above I would like to know if I have already some PV plants installed, on ground and on water, with some temperature records, on the panels and the ambient, how can I calculate an average of the resulted Uc along the years?
is there any equation I can use for checking during the previous years, according to the Ambient/Panel temperature ratio, what was the real Uc factor to be used?
many thanks
David.
