Stupid Question

[wtfg]

I just installed a system but waiting for xcel to install meters .
I have 21 Canadian Solar 325 watt panels with Enphase 7+ micro inverters.
6.825 KW but my actual power is 6090 KW.
Did i use the wrong inverters ? Where is did my loss come from?
Thanks

I wouldn't be concerned about that sort of wattage. Your panels are STC rated at 325W, but that is pretty artificial circumstances. If you look at the specs for your panels you may see NOCT ratings too. That will be much closer to what you can expect to get. There are additional factors such as angle to the sun, mains/grid voltage rise causing the inverter to limit its output if your system is grid tied etc.

That's 89% which is very good.
Did some solar company lead you to expect 100%

This time of year I'm happy with 82% of my nominal rating. I wouldn't complain about 89%. I think they rate them for the Equator on the Summer Solstice. LOL

Oh, and the only stupid question is the one you are too stubborn to ask.

I've acquired 10kW of panels in anticipation of a grid-tie system for the house. This inquisitive idiot is about to embark on a quest.
