Seems roughly right. I'm assuming you mean an 8.16 kW system. A very rough estimate on production is take the peak number and multiply by 4 or 5 to get an estimate of the *average* daily production, so 32 to 40 kWh/day. So you're probably going to up around 22 kWh for the today. But it is winter so production will be below average. The shape of the graph makes me think it's mostly a clear day. Lots and lots rounding and assuming but I believe roughly right.
For reference, I was testing my 23 panel 7.9 kWp AC system today for the first time in NorCal, and it generated 21.21 kWh according to Enphase's tracking tools and 19.8 kWh according to Tesla's software. But 2 of my panels aren't working.
All panels facing 135 azimuth with about 30 degree tilt.
Plus we had a lot of cloud-cover in the afternoon so my production fell off a cliff after about 1pm Pacific.
@mnsweeps, same solar system size as you. 3PWs, not sure your PW count, but we’re in SF Bay area. Yesterday started out nicely but clouds moved in. Here’s my comparison charts for then.
Today’s been foggy in the morning and overcast conditions predicted for rest of day, so not much sun getting through. Won’t replenish PWs today. Rest of week from Dark Skies says sunny. Expect to top off PWs by noon tomorrow and start charging my car then. PWs at 74% now.
November (pretty sunny month) was our first full month of using solar. For anyone looking to compare our system/area to yours, here’s our charts for November and so far for December.
I’m assuming the small percentage “To Grid” each day is a normal thing?
