those 2 marked red panels are canadian, I am saying that as soon as installers realized that panels are to big in size because of chimney and boiler pipe they decided to install 2 smaller canadian panels later on and problems started so I think that might be the problem. its south facing garden roof on sun most of the day no trees etc. Installers didn't measur roof properly they came with 18 ja panels, but because of chimney and pipe they realized they are to big, bit unproffesional but I need to solve this issue asap.

Hi guys, I really need help please. Solar Panels: x16 JA Solar 545w; and x2 Canadian Solar 405w Super High Power Mono PERC HiKU. I had this panels installed in may, production was around 6.7kw on sunny day whe 16 JA panels were connected to solis invertor, as soon as 2 canadian panels was connected production will not go over 4.5 kw on sunny day. I am really annoyed by that. Is there any chance that those 2 panels are source of the problem? I hope that inverter doesn't read canadian panels 405w instead JA 545w?I rather have installers back and disconnecting those 2 and have them as decor on roof instead having drop in production. I would really appreciate your advice please. Also what I should get from this system on sunny day as I think there might by something wrong. I am keep on checking on app and inverter when is full sun on them, there is no dirt or shading on them, but I can't go over 4.7kw which is bit shame as it cost me £19000 including 2 pylontech 4.8kw batteries Thank you
