Taken a call from a guy who had an install in April 2011. He has had an email from BG asking him to clarify his TIC/DNC, including make and model of panels.
His MCS cert says DNC at 4kw but he has 18 x 220w (he thinks) panels making 3.96kWp, with an SMA 3800 inverter which is limits the output to 3.8kW.
The guy went back to BG to say he had 3.96kW and they have batted back to him that his TIC cannot be greater than his DNC (4kW on the MCS cert) and to go back to his installer to rectify, but they seem to have gone bust.
"You have given TIC 3.96kw but on the MCS certificate it is showing 4kw
so it can not be possible that TIC may be greater than DNC so kindly
rectify it by contacting your installer directly."
They are witholding his FIT payments until resolved and he is looking for some help but I don't really know how to advise him.
If I were doing the MCS/FIT application I would have put both the TIC and DNC as 3.8kw as this is the limit on the inverter and keeps it simple. It does raise the alarm bells that there will be more in the woodwork like this!
I have been looking at some of the past threads on here about the subject and I am still stumped. Some have argued that the TIC is the number of panels x their wattage; but given BG's reply to the guy above, this is wrong.
Any ideas folks?
