But "Tesla" didn't produce ? Tesla only stored in your system?

PV panels are not from Tesla, are they?

In the end it doesn't say much. If I put a whole acre of panels in Winnipeg I might produce more than you...
I remember you had a LOT of panels. And you're far south, so higher sun angles. So total production (an extensive property...) is not a useful measure.

Not Tesla panels. 10kw array. First full year it met is design spec.
It is interesting that 25% of my production was “stored”. On track for a 9 year ROI

I've been meeting my design spec ever since the first full year 2019. Though I may be 100 kWh below (well, I don't know how it rounds, it may read 6.1 MWh this year rather than 6.2 (design spec) or 6.3).

Curious how your system will behave re:degradation. Sun exposure is higher there, so possibly more harm done w/ heat than here. (Though newer panels, possibly better, and different brand, so hard to compare.)

I don't know whether the weather has become more sunny here, but 7 years in I'm not seeing any of the expected few %-level decline in production.
Maybe the decline will accelerate a bit so that I reach the 92% at 20 years (or was it 25? I forgot)?

Yesterday it was a really nice day, sunny and almost hit 40*. even with the sun and warm temps, some panels on the E & W sides are still covered or partially covered (S side is clear). Gotta love that one on the east side that gave 11wh - LOL But, the array made 1/2 of what I used yesterday, so that is a huge improvement over the previous 16 days

All snow on the roof will be taken care of by the warm temps and rain later today. Just in time for a flash freeze then more snow tonight/tomorrow

. Snow pack on the ground isn't going anywhere and the paths still show evidence of the light snows I've gotten since the storm on 12/2 (when the paths were snow blown). Even my asphalt driveway still has snow/ice coverage. The ground is just too cold to support melting.

My lifetime production (since late November 2022), with a net export of around 40% of that.

2025 stats.

Produced 12.5 Mwh
Used 15.6 Mwh Of that the car charged 3Mwh
Exported. 5.2 Mwh
Imported. 8.3 Mwh
Battery 3.1 Mwh discharged.

I wish I had report that gave me the $ amount I was paid since my net metering is reset each bill cycle. I’d have go bill by bill. Quick estimate shows I lost $100 versus an unlimited duration net metering l. I’m OK with that. Add 6 months to the ROI break even time. In reality electricity rates will change by more than that in the next few years and will have probably more effect on ROI.

 

[stoveliker]

Yes price increases have been very impactful for ROI calcs here - because they compound.

Yesterday was my first 30kwh + day since November 11th! Not a could in the sky.

I still have way too much snow on my panels to make any production even though it was actually sunny yesterday. Not supposed to be warm enough for any melting before the next storm on Sunday, so probably stuck at 76kwh for the month of January. Assuming that is the case, this would be my 2nd lowest all time month - all 3 lowest months, have been the last 12 months (starting Feb 2025), and all have been under 90kwh.

I've only had 3 days this month where my panels were totally clear of snow/ice AND having at least some sun.

 

[EatenByLimestone]

I noticed my neighbor’s panels were wholly covered yesterday too.

 

[stoveliker]

Almost there....
Yesterday's production. Sunny day.

Forecast is calling for 3-6” of snow here but it could be twice that. I think we’re going to get snow! Now second year in a row and I need think if it it slides off panels will it hit the heat pump unit…..

 

[stoveliker]

Lol, standard install knowledge here. Compressors only at the gable ends...

They say another 9 inches here. Don't know where to shovel that with piles already 6 ft above the driveway... (3?5 ft piles on 2.5 ft higher ground). Going to be hard to throw it over that so it doesn't roll back down onto the driveway...

Edit: yay, forecast says 3-4" now.
But 45 mph winds and a real feel high of -1...
