Hi Folks,
We had our system installed last February, it went 'live' on the 2nd of March. We have around 11kw of panels situated on the E,S & W elevations of our roof on a square house. No shade from trees etc.
The most I've ever seen being produced is 5.33kw or there abouts. Today, with the sun pretty much directly overhead I'm getting 5.33kw, 3 months on with the sun higher in the sky than way back at the beginning of March.
Something doesn't seem right. Is there some kind of capping going on with the Fox system?
Any advice gratefully received!
Cheers,
Jon
Can you provide a bit more information please,
which inverter do you have, how many strings do you have connected, and how are they connected i.e. E, S, W on 3 strings, or 2 strings with E, S&W etc.. and do you have any optimisers fitted

I’m seeing something similar. I have a 9.6kW system of 20 panels split East and West with 4 strings connected to a 10kW KH inverter. In the past I have seen peak generation hitting 6-7 kW but at the moment I am getting less than 5.5 despite all the sun.
I wondered if it was caused by a degrading of panel efficiency with the heat. But I did upgrade the inverter firmware last so am suspicious of that.

6.16kWp of panels, spent most of yesterday and total around the 4kW mark.
The heat is brutal, but production overall is good as the days are longer.
Spring is higher, but overall production is lower due to shorter days, your annual figures are the best overall measure of system.
