Only 11.9 kWh today due to clouds, but my near-perfect day in the past week is 16.7, compared to a max of 42.8 (and might be able to get slightly higher since that was pre-PTO.) This on an 8.19 kW solar roof split evenly north/south.

Just glad the numbers should start trending up again.

3.8kW system, 16 kWh, cool weather, sunny all day, not a cloud. Bell curve like SMAlset.:)

While production has been very good this month here, rainfall is practically nil. 1" since 1 Oct. 5.+ seasonal norm and last year was 7" at this time.

Late to the party. 17.5kW PV with 14.4kW inverters. Partly-cloudy day yesterday, so about 3/4 of my non-cloudy winter generation (~44) and about 3/10 of my peak (~110) since PTO in early June. Joy of being in the north

25.1 kWh from my 13.32 kWp Solar Roof on a clear day in San Jose yesterday. Within about a month of the winter solstice a tree in my neighbor's yard provides some afternoon shade, the shelf at the end is a brief period where the sun dips below the leaves before it goes below the neighbor's roof.

The Tesla app reports 25.4 kWh, but that includes ~20W continuous solar production reported even when the sun is down, so I deduct that from my official number for what I upload to PVOutput.

Looking forward to those longer days of higher sun again, though I guess at some point it'll start to rain again here. :p

I'm trying to understand my production (new system just installed and got PTO). My numbers seem no where near what others with similar charts as mine (16.32KW system). We had a little cloud cover until 10am and then mostly sunny with a few high clouds later in the day. I looked and from 10:05am - 1:10pm I was producing over 5KW at all times with it reaching as high as 9KW but mostly staying in the 7's to 8's. By 1pm it said I generated a total of 12.2KWH which seems low since for 3 hours I never went below 5. Total for the day 15.3KWH.
