Today is the shortest day of the year... how was your production?

[BrettS]

So today is the winter solstice, which is the day with the shortest amount of daylight. How was your production today?

My 15.12kW system produced 37.3kWh, which I don’t think is too bad, considering the fact that there was some cloud cover today. Friday was a nearly cloudless day and I produced 44.8kWh.

My 14.5K system only produced 23kwh. 1/3 of my panels face west and have my house block so very poor. But, since not a lot of rain yet, much higher than it will be once the rain starts.

5.2kwp south facing on 3.8kw inverter generated 21kwh today

 

[Laketime]

6KWH but the snow didn't fall off 2/3rds of my system until noon and the other 1/3 mostly cleared around 2:30 lol.

It was a nice sunny day here. Production 27.5 kWh (I get max of 65-70 kWh in summer).
(9.2 kW system)

Yesterday, 4.08kw system in Southern CA.

Winter is still OK for those with south facing panels. Mine are east and west for 11.8 kW system.
I'll produce about 19.3 kWh today

Has anyone ever seen the energy generated in a day jump afterwards? Mine said 21.7 when I checked at sunset then when I checked it a while later it went down to 20.4.

Don’t be jealous
5.1kWh system. Indiana and it rained all day

21 kWh, from my 8.7kW system. This is consistent with previous years around this time. My max production in june is mid june is about 50-54kWh and around this time its 19-22 kWh

Boston

1.6 kWh from 10.16 kW array - 50% still covered by snow after last week storm + foggy day today.

Just got a system two weeks ago, so personal best is 17.8 kWh.

That is my issue, with 15 of my 47 panels facing west, and getting shading from my tall garage next to them. I get over 80 in the summer when the south and west panels all work

 

[mnsweeps]

Los Angeles area.. 8.16 kW system and got 22.8 kwh.

 

[Laketime]

Damn I sure am jealous of you Cali people and your endless sun...

8 kw (DC) system here, but 2 of my panels (worth 9% of the total) aren't working... so this is more like a 7.3 kw (DC) system.

The Tesla app says I generated 27.1 kWh
The Enphase app says I generated 26.0 kWh

Tesla's data consistently over-states the Enphase data by 4%. I can't tell if this is standard error; but it is sus that the Tesla data is always higher than the Envoy data by 4%. The Envoy sits between the panels and the Gateway 2.

so with 47 panels you get 80 in summer so I guess I will get around 40 plus in summer in L.A area?

Yup. 29.2 kWh from 11.7 kWp west facing panels for sunny shortest day...

 

[sorka]

Two days of fog with NO sun at all. My 8.16KW system made 3.2kWh today from ambient light. Yesterday was 7.2. Two days ago it was foggy in the morning but it cleared by 10 am and I made 31.1. The last completely clear day for me was 12/14 and I made 35.7 kWh.

 

[Zaxxon]

This is my 2nd system, and faces north and east. Also still has some snow on it from last week. 4.9 kW:

The 4.2 kW system on my better two roof faces (non-Tesla) made 10 kWh today.
