I guess I can't really complain too much here. My production is certainly down, but nothing like the ratios in this thread.
My Enphase system is only 16 x 300 watt panels for just 4.8 KW total. That small system made 15.4 KWHs on 12/01 and 15.3 KWHs on 12/02 So I am doing a bit over 3 sun hours still. It's not quite enough to keep up, but it is getting me well past 9 pm after it goes to the lower overnight rate. So I have been manually kicking it to charge a bit from grid at the cheap rate.
My DC system is not doing as well. I think the shadows are playing havoc with the cheap MPPT controller. My 2,000 watts of panels only made about 5 KWHs each of the last 2 days. That only 2.5 sun hours. The really bad rainy days were much worse, but here, we don't get too many of those. I had a day where my 4.8 KW Enphase system only made 1 KWH, but this year, my worst day in Nov. still pushed 3.8 KWHs.
Tomorrow will be interesting. The forecast shows it being sunny to 10 am, then partly to mostly cloudy the rest of the day. And then cloudy again all day Monday. Then we may see sun again Tues. and Wed.
Dec. 20th is the winter solstice. After that, the days will start getting longer again, and the sun angle will start to come back up and clear the tress more too.
