Hi Guys
Need your expert opinions and advice here - I have a solar array installed comprising the 15 panels connected to a Fronius 3.0 IG TL. I just checked the voltage being registered from the array (given it is cloudy and rainy conditions at the moment) and total voltage from the array was 530V.
Now, the N235s are rated at 43.0V per panel. I have them connected in a series on one string of 15 so I was expecting a voltage of
15 x 43.0 = 645V
However, I don't know if conditions affect the voltage (or just affect the current, hence reducing the power output). For information, power output was low at around 200W (so current was 0.35A ish).
I am concerned that maybe not all the panels are connected/functioning - I have been comparing my outputs with another owner with a similar array (but 17 N235s and different Inverter) and, even after allowing for the smaller size of my array, my outputs especially on sunny clear days are significantly smaller than his. I will now monitor what voltage I get on sunny clear days (if we have any more this side of Christmas!) but I haven't done so up to now.
Your thoughts would be appreciated.
Many thanks
Richard
