Confirming installation is workingproperly.

[Garfy117]

Hi all,
apologies in advance; very new to all this so these may be stupid questions!
I had a solar install completed yesterday, consisting of 2 strings of 7 panels. Total installed capacity is 4.7KW.

There are a couple of things that are making me question whether the system is working properly. Firstly, it's generating about 1KW at the moment (11 am, early feb, bright with no clouds and south west facing). There's no shading I can see. Is that a reasonable output given the time of year?

Secondly, the 1st string has a consistently much lower output than the 2nd (generally around a 30:70 ratio). They're in the same location and orientation, one row above the other. PV1 has 2 TIGO's installed, and PV2 has a single one (there's a gas flue that can cast a shadow at certain times).

Am I just being paranoid, or is it possible there's an issue with one or other of the strings?

Thanks,
Gareth

I think its too early to draw conclusions - my 4kw system (at 11.18am) is producing just over 1kw and we have no shading.

Thanks. I'll keep an eye on it for a while before panicing, then!

keep an eye on it and take written records, so if you have to go back to the installer you will have facts on the output

My own system got to a wonderful 800w, but I have shading issues this time of year
