68% is a bit lower than I'm seeing but my panels are adjustable tilt
I'm averaging a bit over 72%
Haze and wispy clouds aren't helping

I'm not saying today is humid
I'm just saying there are fish at the birdfeeder

Odd observation the other day.
Frequent passing clouds would choke off production but when the sky cleared I was seeing about 85% and then slowly taper off

That might be a temperature thing. They cool off in the shade, and when sun hits, the output goes up, but then they get warmer and output drops.

I expect to have below average output as my panels are oriented flat.
I forget what the term is for the boost of energy you get when the sun pokes out from the clouds. It is a well known phenomenon.

I've got 10 panels on my garage roof, and I believe the system is supposed to be 2kw (they've been up there for 14 years and I don't remember the details). I remember getting about 1600w on a good summer day, then turning the hose on them and watching the output go up to 2100w or more as they cooled.

that is cool. maybe i should put water misters around mine!
