Hello all, hope this is of some interest. I could find very few results of actual installed systems on the forums, so this may be of some help.
Just had (Thursday 13th Oct) a 15 x (could not fit 16, not enough space) Sanyo HIT-N240SE10 panels + Fronius IG-TL 3.6 inverter.
Location, sunny(?) Poole, Dorset, very nearly South facing, 40 degrees pitch. 12 panels on main roof, 3 on a gable end (same orientation). Slight morning shading from neighbour's tree, slight evening from gable onto main roof.
First impressions - the inverter is very quiet, slight buzz above 1.5kW output, fan cuts in at about 1.8kW; perhaps equal to someone talking quietly.
The inverter goes down to 100W or less output before quitting!
The output fluctuates wildly as clouds go over - often 300W to 2kW within a minute - makes planning use of the generated power a challenge!
640V DC off the panels even at a pathetic 220W AC output from inverter.
Peak output observed so far 3.3 kW (Saturday).
Cloudy Friday, 7 kWh output; sunny periods Saturday, 13 kWh ; cloudy Sunday, 7kWh.
An impotant tip: I made a scale cardboard plan of my roof and cut card rectangles for panels. By putting them in different arrangements I managed to get FOUR more panels on than my installer's software was saying (!!). Software output is only as good as the input one puts in.....
Any questions feel free to ask.
